ｉ画台数ｎとしてディスクユニット４に出力している。(Prior Art) It is well known that production management is performed using computers. As a method of this kind, there is a production control method carried out by a configuration as shown in FIG. 3, a part of which is a production control system. According to this production control method, for example, in order to obtain the daily planned number n of cars produced every day from the number N of 4 production units such as automobiles, the total planned production number N is read from the 70xB disk 1 into the production control system. In the next step, the start date Ts and the end date Te, which are the production period for the total production #number of units N, will be set as follows:
, search the calendar pre-stored on disk 22, and set the specified production period Ts.
Enter the number of operating days between -Te0 into the total production system 7, divide the planned number of 1gg production units N by the number of operating days, round the remainder to the first decimal place, and calculate the value per day, t
It is output to the disk unit 4 as the number of i-screens n.

容となっている。(4 points for the invention to solve) However, according to the above-mentioned biomass management method, for example, the total planned production number N = 100 units, the number of operating days 1 <= 7 days, and the daily planned number of units. n is n=N/to=1 year old 2
86, so n=14 units. However, n==1
If production continues for 7 days based on the number of units in 4, nv
k = 98 units, which is 2 units less than the total planned production number. Also, when N = 100 units and k = 6 days, N
/ = 14667, and rounding off results in n = 17 units. If production is continued for 6 days based on the number n=17, n-==102, which is an increase of 2, and an error will occur with respect to the total planned production number. Therefore, the production schedule sheet output to the disk unit or printer is always corrected by the production manager.

利な生産管理方法を提供することを目的とする。Therefore, in order to allocate the total production plan number planned within a predetermined period, the total production plan number is evenly allocated within a predetermined period, and then the predetermined period is divided by the remaining number based on the remaining number. Then, by calculating the correction date to correct the equal quota number equally allocated to each divided section and determining the daily production number, the total planned production number and the total quota number after allocation will be equal. By doing this, after executing this total 1, there will be no error between the number of strokes and the actual number, and when determining the number of allocations, it is possible to calculate the correction date to correct the number of allocations. The purpose is to provide a convenient production control method when creating a production planning sheet.

Calculated by k. This mouth allocation board aN is a set number that is evenly allocated to the TeO threshold from the management target period Ts. Next, the remaining revision d is obtained by subtracting the 4 allocated number i from the total planned production number N, that is, calculated by a=N-d. Note that the remaining positions B and d are equal to the total section a, which will be described later. Then, by subtracting the number of operating days k by the number of remaining employees d, we find the allocation date aJ per remaining employee d, that is, '''

奴が最終的な日当り生産台数ｎ“となる。Here, the median date of each section in is determined. In addition, the section is the number of days from I'e from the U-burying period Ts to the above-mentioned scar section i.For example, if the number of days is 10 days and the number of sections is 2, 10 days is the number of two sections. It is divided into sections, 1st to 5th and 6th to 10th9.The central day of each section is the 5th for the 1st to 5th, and the 8th for the 6th to 10th. . If the number of days is 7 and the number of sections is 2, each ward) will have 1st to 3rd days, 4th to 7th days, or 1st to 3rd days.
Similarly, if the number of days between 1st and 4th and 5th and 7th is 10th, and the median day is 10th, the same formula is used: Ta÷l1nl・1−(a/2 ) is calculated as follows. Then, it is determined whether the remaining number d is positive or negative, and the samurai whose d is positive is already an equal number ζ
Adding 1 to the allocated evenly allocated units anf becomes the final daily production number n''.

ることを特徴とする生産管理方法。(1) A production plan input section, a control period input section, a production allocation processing section, and a production plan output section are built into the computer as a production control system, and the total production plan quantity set in advance is The control period input section reads in the predetermined period for which production is to be controlled, and then the production allocation processing section calculates the daily production plan number from the total production plan number and the predetermined period. The value obtained by rounding up the decimal point of the daily production plan number to the nearest whole number is the number of equal allocations within the predetermined period, and the absolute value of the difference between the total number of uniform allocations and the total production plan number is the number of equal allocations within the predetermined period. Divide the predetermined period into a number of intervals equal to the magnitude of the absolute value of the difference, set the center date of each interval as the correction date, and if the difference is a positive number, all the correction days in each interval are equally allocated. A production control method characterized in that the daily production quantity is determined by decreasing 1 and increasing 1 by 1 if the difference is a negative number, and outputting the daily production quantity by the production plan output section.
