Description

  The present invention relates to a project schedule creation system and is devised so that a project schedule can be automatically created by inputting and setting a minimum amount of data (necessary work items and dates).

In order to carry out the project, a number of different tasks must be performed.
in this case,
(1) Each work has an appropriate number of days according to the work,
(2) It is necessary to complete some other work in advance (on the previous day in time) in order to perform one predetermined work, or conversely, after one predetermined work has been completed (At a later date in time) you will need to do another work,
(3) Specific work in each work must be completed at a predetermined date and time,
(4) All work needs to be completed by the date of project completion.

Therefore, in order to carry out the project efficiently and reliably by the project completion date, a schedule for carrying out the project is created before each work of the project is carried out, and each work is carried out according to this schedule. It is necessary to execute.
In this schedule, it is necessary to determine the number of work days required for each work and on what day and how each work is performed.

For example, in a project where a large plant is installed in a specific location, the date when the plant drawing is submitted to the customer (plant contractor), the date when the main machine is shipped, the plant operation training period, the trial operation period, It is necessary to create a schedule that determines the date for regular meetings, the date for collection, and the date for the final delivery of the plant to the customer.
In this case, it is necessary to set the number of days required to perform each work.
Further, for example, the date when the plant is finally delivered to the customer, the date when the main machine is shipped, and the like need to be executed on a predetermined date.
Also, you must decide the order of each work. For example, the “plant operation training period” must be set in advance (the day before in time) before the “trial operation”.

  In this way, in a project for installing a large plant at a specific location, in addition to the operations shown in the specific examples described above, many operations must be performed, and each operation is related to each other in a complicated manner. .

  In the case of a relatively small-scale project such as a “large winter bargain” in a store (department store, etc.) In addition, a schedule is created in order to efficiently and reliably carry out a series of various tasks related to each other.

In the past, a schedule for executing a project as described above has been created by a veteran experienced person who has previously been in charge of many similar projects.
In order to carry out a project, a large number of various work items are required, and each work item is related to each other in a complex manner. This is because a person who can understand the whole cannot create a schedule that allows each work to proceed smoothly.
Moreover, even for similar projects, different veteran personnel have manually created a schedule for each project from the blank state for each project.

JP 2003-44634 A JP-A-7-296056

As described above, a schedule for carrying out a project could not be created unless it is an experienced person.
In addition, every time a new project is generated, the schedule was manually created from a blank state, so the effort for creating the schedule was extremely large, and it took a lot of time to create the schedule.
Moreover, since similar schedules were created separately for similar projects, there was a problem that the effort for creating schedules was duplicated when viewed as a whole.

  In view of the above-described prior art, the present invention is a project schedule creation system that can easily and quickly create a schedule that can efficiently and reliably execute each work of a project, even if it is not a veteran. The purpose is to provide.

  According to the present invention, even if you are not an experienced person, you can automatically create a project schedule just by entering the required work items and key date dates. It is possible to reduce the number of schedules and prevent a schedule creation error.

Embodiments of the present invention will be described below in detail with reference to the drawings.
The present invention was developed for the purpose of creating a schedule for an extremely large-scale project, such as a project for installing a large plant at a specific location. However, the present invention is not limited to such a large-scale project. It can also be applied to the creation of a small-scale project schedule.

In the following examples, in order to facilitate understanding of the technical contents of the present invention, a relatively small-scale project that is a relatively small-scale project, such as a store (department store, etc.) and a large winter bargain, is described. A case of creating a schedule will be described.
Of course, the present invention can also be applied when creating a schedule for a large-scale project.

FIG. 1 is an example of a schedule created by the schedule creation system according to the first embodiment of the present invention. This schedule is a schedule for carrying out a relatively small-scale project of “big winter bargain” at a store (a department store or the like).
The schedule shown in FIG. 1 is a system configuration and a variety of data that will be described later, which are output in an organically linked manner.
First, the contents of the schedule that is the output result will be described.

In FIG. 1, “plan” and “sale” are major items.
"Planning", "Product arrangement", "Clean up" and "Sale" are work items.
“Current status analysis”, “immediate meeting”, “regular meeting”, “product check”, “product arrival”, “product order”, “product inventory”, “clearing”, “cleaning up”, “sale”, and “others” are detailed work items.

And the high-level items of the detailed work items of “current analysis”, “immediate meeting” and “regular meeting” are work items of “planning review”
The upper items of the detailed work items “product check”, “product arrival”, “product order”, “product inventory” are work items called “product arrangement”,
The high-level items of the detailed work items "clearing" and "cleaning up" are work items called "clean up"
A high-order item of detailed work items “sale” and “others” is a work item “sale”.

Furthermore, the top items of the work items of “planning study” and “product arrangement” are the large items of “planning”
The upper items of the work items “clean up” and “sale” are large items “sale”.

In FIG. 1, the period and date indicated by a white bar beside each detailed work item are the period and date for executing each detailed work item. In this example, the period from June to December of 2006 is arranged in the horizontal direction.
For example, the detailed operation “current state analysis” indicates that the operation starts on June 8, 2006 and ends on September 8. Further, for example, the last meeting is held on December 9, 2006, and the regular meeting is held on August 15, September 15, and October 15.

Further, “planning / consideration start date”, “planning / consideration end date”, “sale preparation completion date”, and “sale start date” are also displayed as key date information.
The key date information is information that the schedule creator inputs / sets key date information necessary for the system, and the input / set information is displayed in the schedule. The date of each key date is displayed as a day indicated by a white vertical down arrow.
In this example, “date of planning / consideration” which is key date information is August 15, 2006, and “date of planning / consideration” is October 15, 2006. The “completion date” is December 1, 2006, and the “sale start date” is December 10, 2006.

  Although detailed calculation processing procedures will be described later, the schedule of the detailed work items related to (linked to) the key date information among the detailed work items is determined based on the date set in the key date information. Based on the detailed work item for which the schedule has been determined, the detailed work items related to (linked to) the detailed work item for which the schedule has been determined are sequentially determined.

  Next, the system configuration of the schedule creation system of this embodiment will be described with reference to FIGS.

  FIG. 2 shows the physical configuration of the schedule creation system of this embodiment. In the present embodiment, various personal computers 300 are connected to the server 100 via a communication line (wireless or wired communication line) 200.

  A user (schedule creator) 400 operates an arbitrary personal computer 300 to input necessary information (such as work items and dates). The input information is transmitted to the server 100 through the communication line 200, and the server 100 performs arithmetic processing to automatically create a schedule. The automatically created schedule is transmitted to the personal computer 300 through the communication line 200 and displayed on the display screen of the personal computer 300, and the schedule is printed out as necessary.

  FIG. 3 shows a logical configuration of the schedule creation system of this embodiment. In the present embodiment, the server 100 includes a data list 110 and a function list 120.

  The data of the data list 110 includes project information 111, key date information 112, large item information 113, work item information 114, detailed work item information 115, template key date information 116, template large item information 117, template work item information 118. Template detailed work item information 119 exists.

  The function list 120 includes a template key date information editing function 121, a template large item information editing function 122, a template work information editing function 123, a template detailed work information editing function 124, a project information registration / editing function 131, a key date information registration / Editing function 132, work information registration / editing function 133, detailed work information registration / editing function 134, detailed work information scheduled start / end scheduled date determination function 135, project information input screen creation function 141, key date information input screen creation There are a function 142, a work information input screen creation function 143, a template information editing screen creation function 144, and a process table (schedule) screen creation function 145.

  The personal computer 300 includes a project information input screen 301, a key date information screen 302, a work information input screen 303, a template information editing screen 304, and a process table (schedule) screen 305.

  A user (creator) 400 performs project information input 401, key date information input 402, work information input 403, template information editing 404, and process table (schedule) confirmation 405.

As the template key date information 116, template large item information 117, template work item information 118, and template detailed work item information 119 of the server 100, for example, template information as shown in FIG. 4 is stored in advance.
The contents of the template information 116 to 119 can be changed / corrected (edited) by the template editing functions 121 to 124 and also by the “template information editing 404” operation by the user 400. Can do.

As template information shown in FIG.
(1) Key date information includes “planning / consideration start date”, “planning / consideration end date”, “sale preparation completion date”, and “sale start date”.
(2) Major items include “plan” and “sale”.
(3) Work items include “planning review”, “product arrangement”, “cleanup” and “sale”.
The high-level items “planning” are the upper items of “planning study” and “product arrangement” as work items. In addition, the high-order item “sale” is the higher-level item of “clean up” and “sale” of work items.
(4-1) Detailed work items that are subordinate items of “planning review” of work items include “current situation analysis”, “immediate meeting”, and “regular meeting”.
(4-2) Detailed work items that are subordinate items of “Product Arrangement” in the work items include “Product Check”, “Product Arrival”, “Product Order”, and “Product Inventory”.
(4-3) Detailed work items that are subordinate items of “clean up” of work items include “clearing” and “cleaning up”.
(4-4) The detailed work items that are subordinate items of the “sale” work item include “sale” and “others”.

For each detailed work such as “Analysis of Current Status”, [Work Days], [Detailed Tasks to be Linked] or [Key Dates to be Linked], [Interval with Linked Targets], [Relationship with Linked Targets] The calculation condition is set.
In addition, the “regular meeting” includes operations such as [work days], [regular schedule], [key date to be linked to the start of the regular schedule] [key date to be linked to the end of the regular schedule] The condition is set.

Explaining the calculation conditions of “current analysis”, the “working days” is 3 months, which means that the required number of days (period) required for performing “current analysis” is 3 months. .
[Detailed work to be linked] is “Product order” of the detailed work item, which means that the schedule of “Current status analysis” must be determined in relation to “Product order” in time. Yes.
The “interval with the link target” is one month, indicating that the interval between the “current state analysis” and the “product order” is one month.
[Relationship with linked target] is in advance, because the schedule of “current analysis” must be set before (prior) in time before “product order” that is linked It means not to be.

The calculation conditions for “product check” will be described. [Working days] is 10 days, which means that the required number of days (period) required for performing “product check” is 10 days. .
The [date key to be linked] is “sale start date” in the key date information. The “product check” schedule must be determined in relation to the “sale start date” in time. Represents.
The [interval with the target to be linked] is 15 days indicates that the interval between the “product check” and the “sale start date” is 15 days.
[Relationship with linking target] is in advance because the "Product Check" schedule must be set in advance (in advance) before the "Sale Start Date" that is the linking target. It means that it is necessary.

The calculation condition of “clearing” will be described as [working days] being 3 days means that the required number of days (period) required for performing “clearing” is 3 days.
The [date key to be linked] is “sale start date” in the key date information, indicating that the “settlement” schedule must be determined in relation to the “sale start date” in time. ing.
The “interval with the link target” is 0 days, indicating that the interval between “clearing” and “sale start date” is 0 days.
[Relationship with the target of linking] is posterior because the “settlement” schedule must be set later (after the fact) than the “sale start date” that is the target of linking. It means not to be.
In this example, [interval with tying target] is 0 day and [relation with tying target] is posterior, so “clearing” is the same day as “sale start date”. It represents what happens after the sale starts.

The calculation condition of “regular meeting” will be described. [Working days] is one day, which means that the required number of days (period) necessary for “regular meeting” is one day.
[Regular schedule] is 15th of every month indicates that a regular meeting is held on the 15th of every month.
[Target key date linked to the start of a regular schedule] is the planning / consideration start date of key date information. This means that it must be determined. Specifically, this means that the first “regular meeting” is decided after the planning / consideration start date.
[Target key date linked to the end of a regular schedule] is the planning / consideration end date of key date information. This means that it must be determined. Specifically, this indicates that the last “regular meeting” is determined in advance of the planning / consideration end date.

  The calculation conditions for other detailed work items are also set to represent the same as described above.

  The template information shown in FIG. 4 is constructed to create a schedule for performing a “bargain” project at a store. If a date or the like is input using this template information, a calculation process described later can be performed to create a “bargain” schedule.

  Therefore, a user 400 in Tokyo can create a schedule for “Winter Bargains” in a store in Tokyo, for example, by accessing the server 100 using the personal computer 300 installed in Tokyo and performing arithmetic processing. In addition, for example, another user 400 in Osaka can use the personal computer 300 installed in Osaka to access the server 100 and perform calculation processing, thereby creating a schedule for “summer bargains” in stores in Osaka. .

  Next, a method of creating a schedule in the server 100 when one user 400 inputs a work item or a date using the personal computer 300 of the terminal will be described.

  As shown in FIG. 3, the user 400 performs a project information input 401, a key date information input 402, and a work information input 403. FIG. 5 schematically shows these inputs.

  3 and FIG. 5, the user 400 inputs the project information 401 using the personal computer 300 and inputs “Winter Great Bargain” as the project name. This project name “Great Winter Bargain” is stored as the project information 111 of the server 100.

The user 400 performs key date information input 402 using the personal computer 300 and inputs key date information.
Specifically, enter August 15, 2006 as the start date for planning / examination, enter October 15, 2006 as the end date for planning / examination, and enter December 1, 2006 as the date for completing the sale preparation. Then, enter December 10, 2006 as the sale start date. Such key date information is stored as the key date information 112 of the server 100.
That is, when the user 400 inputs key date information, the name of the key date information such as “plan / consideration start date” is obtained from the template key date information 116, and the date of the key date information such as August 15, 2006 is The data are transferred from the personal computer 300 used by the user 400 and stored together as key date information 112.

The user 400 performs work information input 403 using the personal computer 300. That is, it is selected whether or not each piece of work information displayed on the personal computer 300 such as “planning study”, “product arrangement”, “cleanup”, and “sale” is necessary. In this example, it is selected that all the pieces of work information “planning examination”, “product arrangement”, “cleaning up”, and “sale” are necessary, and the necessary work information is input.
The selected (input) work information “planning examination”, “product arrangement”, “cleanup”, and “sale” is stored as work item information 114 of the server 100.
That is, when the user 400 selects specific work information as necessary, the name of the work information such as “planning review” is obtained from the template work item information 118, and information indicating that the work information is necessary is displayed by the user 400. Each is transferred from the personal computer 300 to be used, and is collectively stored as work item information 114.

When the user 400 selects each piece of work information as “planning review”, “product arrangement”, “cleaning up”, and “sale” as necessary work information, the server 100 displays the upper items of “planning examination” and “product arrangement”. A large item “plan” and a large item “sale” which is a higher item of “clean up” and “sale” are transferred from the template large item information 117 to the large item information 113.
At the same time, subordinate items of “Planning Review” are “Current Status Analysis”, “Previous Meeting”, “Regular Meeting”, and “Product Arrangement” are subordinate items “Product Check”, “Product Arrival”, “Product Order”, “Product Inventory” ”,“ Clearing ”,“ Clearing ”, which are subordinate items of“ After Cleaning ”, and“ Sale ”,“ Other ”, subordinate items of“ Sale ”, are transferred from the template detailed work item information 119 to the detailed work item information 115. Is done.

  In other words, necessary information among the template information 116 to 119 is transferred (copied) as the information 112 to 115 by data input by the user 400. In this example, all key date information, large item information, work item information, and detailed work information are transferred.

  However, for example, when the user 400 determines that the work item “clean up” is unnecessary and does not input the work item “clean up”, the work item “clean up”, and The subordinate items “clearing” and “cleaning up” are not transferred from the template information 118 and 119 as the information 114 and 115.

Transfer (copy) from the template information 116 to 119 to the information 112 to 115 is performed by the registration function of the registration / editing functions 132 to 134.
The storage in the project information 111 is performed by the registration function of the project information registration / editing function 131.

  When the information 111 to 115 is stored (registered) as described above, the server 100 is set to each detailed work item by the scheduled start date / scheduled end date function (calculation function) 135 of the detailed work information. Calculation processing is performed based on the calculation conditions, and the scheduled start date and scheduled end date of each detailed work item are sequentially determined. This calculation processing method will be described later.

  In order to determine the scheduled start date and the scheduled end date of each detailed work item, arithmetic processing described later is performed for each detailed work item, and the detailed work item is sequentially determined for each detailed work item. At this time, if it is not possible to determine the scheduled start date and the scheduled end date for the detailed work item even after the computation process, the determination of the scheduled start date and the scheduled end date for the detailed work item remains undecided, and the next detailed work The process proceeds to calculation processing for determining the scheduled start date and the scheduled end date of the item.

  The order of the detailed work items for which the scheduled date is determined (calculated) may be random or may be a predetermined order. In any case, calculation processing for determining the scheduled start date and the scheduled end date is performed for all detailed work items (although the calculation date may not be determined even if calculation processing is performed, the calculation processing itself is performed). . In this manner, performing the calculation process for determining the scheduled start date and the scheduled end date for all the detailed work items is referred to as “schedule determination process” herein.

When the first “schedule determination process” is completed, the second, third, fourth,...
When performing multiple "schedule determination processes", the scheduled start and end dates of each work item determined in this "schedule determination process" and each of the items determined in the previous "schedule determination process" When the scheduled start date and the scheduled end date of the work item match, the calculation process ends.
Then, the scheduled start date and the scheduled end date of each work item obtained by this “schedule determination process” are determined as the dates of the detailed work items in the schedule.
An example of such a determined schedule is shown in FIG.

Next, based on the template information shown in FIG. 4, the scheduled date determination table shown in FIG. 6, and the scheduled date determination conceptual diagrams shown in FIGS. A calculation processing method to be determined, a schedule determination process, and a method for determining final scheduled start dates and scheduled end dates will be described.
The calculation for determining the scheduled start date and the scheduled end date is performed by the function for determining the scheduled start date / scheduled end date 135 of the detailed work information shown in FIG.

  As shown in FIG. 6, details of “current analysis”, “immediate meeting”, “regular meeting”, “product arrival”, “product order”, “product check”, “product inventory”, “clearing”, “cleaning up”, “sale”, and “others”. The scheduled start / end dates of the work items are sequentially determined according to the order in which the detailed work items are arranged (in FIG. 6, from the left detailed work item to the right detailed work item).

  The first “schedule determination process” will be described.

  As shown in FIG. 4, the calculation condition of “current state analysis” is linked to “product order”, and is a calculation condition that is in advance of the linked “product order”. However, since the date of “product order” has not been determined, the date of “current state analysis” is not yet determined.

As shown in FIG. 4, the calculation condition of “immediate meeting” is linked to “sale start date”, and the schedule is one day ahead of this linked “sale start date”. The number of days is one day.
Therefore, by searching for the “sale start date” to be linked and taking this “sale start date” December 10, 2006 into the calculation condition, Month 9 is set as the scheduled end date of the “immediate meeting”, and the number of working days per day is added to the scheduled end date, and December 9, 2006 is determined as the scheduled start date of the “immediate meeting”.

As shown in FIG. 4, the calculation condition of “regular meeting” has a start date linked to “plan / examination start date”, an end date linked to “plan / examination end date”, and On the 15th of every month.
Therefore, the “planning / examination start date” and the “planning / examination end date” to be linked are searched, and the “planning / examination start date” and the “planning / examination end date” are August 15, 2006.

  The scheduled start date and scheduled end date of each work item determined in the third “schedule determination process” and the scheduled start date and scheduled end date of each work item determined in the fourth “schedule determination process” Since they match, the calculation process is terminated.

  Then, the scheduled start date and the scheduled end date of each detailed work item obtained by the fourth “schedule determination process” are determined as the final date of each detailed work item in the schedule.

  The server 100 transmits the data of the scheduled start date and the scheduled end date of each detailed work item determined in this way to the personal computer 300 via the transmission circuit 200. The schedule shown in FIG. 1 shows the scheduled start date and the scheduled end date of each detailed work item transmitted as described above as a calendar-type schedule.

FIG. 12 is a flowchart showing a series of arithmetic processing.
The project information, key date information, and work information are input in steps S1 to S3, the project information, key date information, and work information are registered in steps S4 to S6, and the detailed work information associated with the detailed work information in step S7. Make a copy.
In steps S8 to S12, a plurality of schedule determination processes are performed.
When the scheduled start date and the scheduled end date of each detailed work item are finally determined, they are registered in step S13 and output in step S14.

  In addition, after the final scheduled start date and the scheduled end date of each detailed work item are determined, if it is desired to add a new work item to the schedule, the details included in the new work are included in the determined detailed work. By adding the work and performing a calculation process similar to that shown in FIG. 6 for the new work, the scheduled start date and the scheduled end date of the new detailed work item included in the new work item are determined.

In the first embodiment, when the scheduled start date and the scheduled end date of a certain detailed work item are determined by the specific number of schedule determination processes, the scheduled start date of the detailed work item is also determined in the subsequent schedule determination process. The scheduled end date was not changed.
For example, as shown in FIG. 6, “Product Check” has its scheduled start date (November 16, 2006) and scheduled end date (November 25, 2006) determined by the first schedule determination process. In the subsequent second to fourth schedule determination processes, the scheduled date is not changed.
However, when a plurality of key dates are linked to a specific detailed work item, even if the scheduled start date and end date of the specific detailed work item are once determined, the schedule of the number of subsequent times Due to the determination process, the scheduled start date and the scheduled end date of the specific detailed work item may be changed.
In the second embodiment, it is described that the scheduled start date and the scheduled end date of a specific detailed work item may be changed when the schedule determination process is performed a plurality of times.

In addition,
(1) A calculation method for determining the scheduled start date and scheduled end date of each detailed work item,
(2) Perform multiple times of “schedule decision processing”, and the scheduled start and end dates of each detailed work item decided in this “schedule decision processing” and each detail decided in the previous “schedule decision processing” When the scheduled start date and scheduled end date of the work item match, the computation process ends, and the scheduled start date and scheduled end date of each detailed work item obtained by this "schedule determination process" The method for determining the date of a detailed work item is
The same applies to the second embodiment.
In the second embodiment, when a plurality of dates are input in the associated key date information, a determination condition for determining which date is used as the date of the key date information is set.
The “determination condition” is, for example, a condition that is determined according to the priority order registered in the template information in advance when the detailed work item extends over a plurality of work items, and the detailed work item is the same. In the case of a work item, the condition is determined from the detailed work item associated with the work item.

  Accordingly, here, referring to FIG. 13 to FIG. 15, when the schedule determination process is performed a plurality of times, the scheduled start date and the scheduled end date of a specific detailed work item may be changed. I will explain.

The preconditions for the occurrence of a state that “when the schedule determination process is performed a plurality of times, the scheduled start date and the scheduled end date of a specific detailed work item may be changed” are as follows.
(1) Multiple key dates can be set. For example, a case where a plurality of “sale start dates” are set. A plurality of work items that are higher-level items of detailed work items associated with a plurality of set key dates can be set.
(2) If the detailed work associated with the detailed work is in the same work item, the priority order of the detailed work is always determined in the same work item.
When the detailed work associated with the detailed work extends over different work items, the priority order (late date or early date) registered in the template information in advance is followed.
(3) When a plurality of key dates are set, the determination date may be changed for the same detailed operation in the detailed operation date determination process.

FIG. 13 shows an example of template information, with X and Y as template key dates, A and B as work items, and α, β, and γ as detailed work items included in work item A as work items B. As detailed work items included, δ, ε, and ζ are set.

  It should be noted in FIG. 13 that the detailed work γ included in the work item A is linked to the detailed work item ε included in the work item B. ζ is linked to the detailed work item γ included in the work item A. That is, it should be noted that the detailed work associated with the detailed work may straddle different work items.

FIG. 14 shows input data, in which two key dates X1 and X2 are input as key date X, and two key dates Y1 and Y2 are input and set as key date Y. According to Y2, work items A1, A2, B1, and B2 are input.
The work item A1 includes detailed operations α1, β1, and γ1, and the work item A2 includes detailed operations α2, β2, and γ2.
The work item B1 includes detailed operations δ1, ε1, and ζ1, and the work item B2 includes detailed operations δ2, ε2, and ζ2.
After all, it is necessary to determine the scheduled start date and the scheduled end date for each of the detailed operations α1, β1, γ1, detailed operations α2, β2, γ2, detailed operations δ1, ε1, ζ1, and detailed operations δ2, ε2, ζ2. .

FIG. 15 is a determination table for scheduled start / end dates, and corresponds to FIG. 6 in the first embodiment.
In FIG. 15, the second line from the top indicates each detailed work for which the start date and the end date should be determined, and the first line from the top is associated with each detailed work item described in the second line from the top. Template data is shown.
In FIG. 15, the third to sixth lines from the top indicate the first to fourth schedule determination processes.

Each detailed work item described in the second line from the top in FIG. 15 is associated with the template information described in the first line from the top.
Specifically, the following calculation processing is set for each of the target detailed operations for the linked target.
The detailed work α1, which is the target detailed work, is linked to the key date X1.
The detailed work β1, which is the target detailed work, is linked to the detailed work α1.
The detailed work γ1, which is the target detailed work, is linked to the earlier one of the detailed work ε1 and ε2 across different work items (in this example, ε1), but the schedule of the detailed work ε1 has not yet been determined. However, if the detailed work ε2 is determined first, it is temporarily linked to ε2, and in the subsequent schedule determination process, if the schedule of the detailed work ε1, ε2 is determined, the earlier one of ε1, ε2 (this In the example, it is linked to ε1).

However, if the detailed work γ2 is determined first, it is temporarily linked to γ2, and in the subsequent schedule determination process, if the schedule of the detailed work γ1, γ2 is determined, the earlier one of γ1, γ2 (this In the example, it is linked to γ1).

The detailed work α2 that is the target detailed work is linked to the key date X2.
The detailed operation β2, which is the target detailed operation, is linked to the detailed operation α2.
The detailed work γ2 that is the target detailed work is linked to the later one of the detailed work ε1 and ε2 across different work items (ε2 in this example), but the schedule of the detailed work ε2 is undecided However, if the detailed work ε1 is determined first, it is temporarily linked to ε1, and in the subsequent schedule determination process, if the schedule of the detailed operations ε1, ε2 is determined, the later one of ε1, ε2 (this In the example, it is linked to ε2).
The detailed work δ2 that is the target work is linked to the key date Y2.
The detailed work ε2, which is the target detailed work, is linked to the detailed work δ2.
The detailed work ζ2, which is the target detailed work, is linked to the earlier of the detailed work γ1, γ2 across different work items (in this example, γ1), but the schedule of the detailed work γ1 has not yet been determined However, if the detailed work γ2 is determined first, it is temporarily linked to γ2, and in the subsequent schedule determination process, if the schedule of the detailed work γ1, γ2 is determined, the earlier one of γ1, γ2 (this In the example, it is linked to γ1).

The first schedule determination process will be described.
The schedule of the detailed work α1 (scheduled start date and scheduled end date) is taken in the date of the key date X1 linked to this, and the calculation conditions (the number of work days of α1 and the linked target are set in the detailed work α1) The date (scheduled start date and scheduled end date) of the detailed work α1 is determined based on an interval with a certain X1 and a relationship (preliminary and subsequent) with the target X1 to be linked.

  The schedule of the detailed work β1 (scheduled start date and scheduled end date) is taken in the date of the detailed work α1 linked to this, and the calculation conditions (the number of work days of β1 and the linked target are set in the detailed work β1) The date (scheduled start date and scheduled end date) of the detailed operation β1 is determined based on an interval with a certain α1 and a relationship (preliminary and subsequent) with α1 that is a linking target.

  The schedule of the detailed operation γ1 (scheduled start date, scheduled end date) cannot be determined because the detailed operations ε1 and ε2 associated therewith have not been determined.

  The schedule of the detailed work δ1 (scheduled start date and scheduled end date) is taken in the date of the key date Y1 linked to this, and the calculation conditions (the number of work days of δ1 and the linked target are set in the detailed work δ1) The date (scheduled start date and scheduled end date) of the detailed operation δ1 is determined based on an interval with a certain Y1 and a relationship (preliminary and subsequent) with Y1 that is a linking target.

  The schedule of the detailed work ε1 (scheduled start date and scheduled end date) is taken in the date of the detailed work δ1 linked to this, and the calculation conditions (the number of work days of ε1 and the linked target are set in the detailed work ε1) The date (scheduled start date and scheduled end date) of the detailed operation ε1 is determined based on an interval with a certain δ1 and a relationship (preliminary and subsequent) with δ1 that is a linking target.

  The schedule of the detailed work ζ1 (scheduled start date, scheduled end date) cannot be determined because the detailed tasks γ1 and γ2 associated therewith have not been determined.

  For the schedule of the detailed work α2 (scheduled start date and scheduled end date), the date of the key date X2 linked to this is taken, and the calculation conditions (the work days of α2 and the linked target are set in the detailed work α2) The date (scheduled start date and scheduled end date) of the detailed work α2 is determined based on the interval with a certain X2 and the relationship (preliminary and subsequent) with the target X2 to be linked.

  The schedule of the detailed work β2 (scheduled start date and scheduled end date) is taken in the date of the detailed work α2 linked to this, and the calculation conditions (the number of work days of β2 and the linked target are set in the detailed work β2) The date (scheduled start date and scheduled end date) of the detailed work β2 is determined based on an interval with a certain α2 and a relationship (preliminary and subsequent) with α2 that is a linking target.

  The schedule of the detailed work γ2 (scheduled start date and scheduled end date) is linked to the later detailed work ε2 of the detailed work ε1, ε2, but the detailed work ε2 has not yet been determined. Since the schedule of ε1 has been determined, the schedule of the detailed work ε1 is taken in, and the calculation conditions set in the detailed work γ2 (the work days of γ2, the interval with ε1 that is the provisional link target, the provisional The date (scheduled start date and scheduled end date) of the detailed work γ2 is determined based on the relationship (preliminary and subsequent) with ε1 that is the object to be linked.

  The schedule (scheduled start date, scheduled end date) of the detailed work δ2 is taken in the date of the key date Y2 linked to this, and the calculation conditions set in the detailed work δ2 (the number of work days of δ2 and the linked target) The date (scheduled start date and scheduled end date) of the detailed work γ2 is determined based on the interval with a certain Y2 and the relationship (preliminary and subsequent) with Y2 that is the object to be linked.

  For the schedule of the detailed work ε2 (scheduled start date, scheduled end date), the date of the detailed work δ2 associated with this is taken in, and the calculation conditions set in the detailed work ε2 (the number of work days of ε2, the target of linking) The date (scheduled start date and scheduled end date) of the detailed operation ε2 is determined based on an interval with a certain δ2 and a relationship (preliminary and subsequent) with δ2 that is a linking target.

  The schedule of the detailed work ζ2 (scheduled start date, scheduled end date) is linked to the earlier detailed work γ1 of the detailed work γ1 and γ2, but the detailed work γ1 has not yet been determined. Since the schedule of γ2 is determined, the schedule of the detailed work γ2 is taken in, and the calculation conditions set in the detailed work ζ2 (the work days of ζ2, the interval with γ2, which is the provisional association target, the provisional The date (scheduled start date and scheduled end date) of the detailed work ζ2 is determined based on the relationship (preliminary, subsequent) with γ2 that is the object to be linked.

The second schedule determination process will be described.
The schedule of the detailed work α1 (scheduled start date and scheduled end date) and the schedule of the detailed work β1 (scheduled start date and scheduled end date) are performed in the same manner as the first schedule determination process.

  The schedule (scheduled start date and scheduled end date) of the detailed work γ1 is linked to the earlier detailed work ε1 of the detailed work ε1 and ε2, so the schedule of the detailed work ε1 is taken in and set to the detailed work γ1. The date of the detailed work γ1 (scheduled start date and scheduled end date) based on the calculation conditions (number of work days for γ1, interval with ε1 to be linked, relationship with ε1 to be linked (prior and subsequent)) ).

  The schedule of the detailed work δ1 (scheduled start date and scheduled end date) and the schedule of the detailed work ε1 (scheduled start date and scheduled end date) are performed in the same manner as in the first schedule determination process.

  The schedule of the detailed work ζ1 (scheduled start date and scheduled end date) is linked to the earlier detailed work γ1 of the detailed work γ1 and γ2, so the schedule of the detailed work γ1 is taken in and set to the detailed work ζ1. The date (start) of detailed work ζ1 based on the calculation conditions (work days of ζ1, interval with γ1 which is a provisional association target, relationship with γ1 which is a provisional association target (preliminary and subsequent)) (Scheduled date and scheduled end date).

  The schedule of the detailed work α2 (scheduled start date and scheduled end date) and the schedule of the detailed work β2 (scheduled start date and scheduled end date) are performed in the same manner as the first schedule determination process.

The schedule of the detailed work γ2 (scheduled start date, scheduled end date) is set to the detailed work γ2 by fetching the schedule of the detailed work ε2 in order to link the detailed work ε1, ε2 to the later detailed work ε2. Based on the calculation conditions (number of work days for γ2, interval with ε2 to be linked, relationship with ε2 to be linked (previous, subsequent), date of detailed work γ2 (scheduled start date and scheduled end date) ).
For this reason, the schedule for the detailed operation γ2 differs from the schedule determined in the second setting process with respect to the schedule determined in the first setting process.

  The schedule of the detailed work δ2 (scheduled start date and scheduled end date) and the schedule of the detailed work ε2 (scheduled start date and scheduled end date) are performed in the same manner as in the first schedule determination process.

The schedule of the detailed work ζ2 (scheduled start date and scheduled end date) is linked to the earlier detailed work γ1 of the detailed work γ1 and γ2, so the schedule of the detailed work γ1 is taken in and set to the detailed work ζ2. The date of the detailed work ζ2 (scheduled start date and scheduled end date) based on the calculation conditions (number of work days for ζ2, interval with γ1 being linked, relationship with γ1 being linked (preliminary and subsequent)) ).
For this reason, the schedule of the detailed work ζ2 differs from the schedule determined in the first setting process with respect to the schedule determined in the second setting process.

  The schedule of each detailed work of the third schedule determination process is performed in the same manner as the second schedule determination process.

  Since the schedules of the detailed operations calculated by the second and third schedule determination processes coincide, the calculation process ends. And the schedule of each detailed work calculated | required by the 3rd schedule determination process is determined as a schedule in a schedule.

Eventually, in Example 2, the scheduled start date and the scheduled end date of the detailed operation γ2 are changed in the second setting process from the date determined in the first setting process.
As the scheduled start date and the scheduled end date of the detailed work ζ2, the date determined in the first setting process is changed in the second setting process.
Thus, in the middle of the schedule determination process, the scheduled start date and the scheduled end date of some detailed work may be changed, but finally each detail obtained by the third schedule determination process The work schedule is determined as a schedule in the schedule.

  The present invention creates not only a relatively small-scale project schedule for bargaining in a store (department store, etc.) but also a large-scale project schedule for installing a large plant at a specific location. It can also be applied to.
