Description

  The present invention relates to a technique for supporting analysis and inspection of substances contained in parts.

  Currently restricting the use of certain chemicals such as the European Union's RoHS directive (Restriction of the use of Hazardous Substances) and the ELV directive (End of Life Vehicles Directive) Laws and regulations are being enacted and enforced in each country. These recent trends in strengthening environmental regulations include the systematization of chemical substance regulations found in the REACH (Registration, Evaluation, Authorization of Chemicals) regulations, and regulations other than chemical substances (such as the obligation to disclose environmental impact information on products). This suggests the possibility of spreading to the addition of.

  Therefore, the assembly manufacturer extracts a part of the parts delivered by the supplier as a sample and analyzes it using a fluorescent X-ray analyzer, an inductively coupled plasma analyzer, etc., so that the chemical substances contained in the parts can be analyzed. The content is checked. At this time, in order to realize more efficient parts analysis, the assembly manufacturer specifies and specifies the constituent materials that are likely to contain the regulated substances in advance using reference information such as Non-Patent Document 1. By extracting the parts in which the component material is used as a sample and checking the content of chemical substances, inspection omissions are prevented.

A determination process is performed (S12). This process will be described in detail with reference to FIG.

  FIG. 10 is a flowchart showing the certification failure risk calculation process in FIG.

  First, the risk quantifying unit 121 extracts one part ID that has not been processed in step S23 from the part ID field 111e of the part attribute table 111a, and records corresponding to the part ID extracted in the part attribute table 111a. Is identified (S20).

  Next, the risk quantifying unit 121 extracts one constituent material included in the part identified by the part ID extracted in step S20, which has not been subjected to the processing in step S23, from the constituent material field 111l. Then, a record storing the same constituent material as the constituent material extracted in the part attribute table 111a is specified (S21).

  Next, the risk quantifying unit 121 extracts one chemical substance contained in the constituent material extracted in step S20, which has not been subjected to the process in step S23, from the chemical substance field 111n, and the component attribute table. A record in which the same chemical substance as the chemical substance extracted in 111a is stored is identified (S22).

  Next, the risk quantifying unit 121 specifies the content rate of the chemical substance in the record specified in step S22 from the content rate field 111o, and specifies an abnormal change in the content rate (S23).

  Regarding the abnormal change of the content rate, two forms of “cliff” and “peak” of the content rate are assumed here, and the risk quantifying unit 121 extracts “cliff” and “peak” of the content rate.

  First, the “cliff” extraction method by the risk quantification unit 121 will be described.

  FIG. 11 is a time series graph of the chemical substance content rate in the record specified in step S22, using the date stored in the registration date field 111k.

  As shown in FIG. 11, “cliffs” are observed at the “change” portion across the average content rate. Such a behavior can be detected by, for example, a method of determining the presence or absence of series correlation using “Durbin-Watson ratio”.

  Specifically, the risk quantification unit 121 assigns a number L (L = 1,...) That is a natural number sequentially from 1 to each lot stored in the lot field 111i of the record specified in step S22. , N (N is the total number of lots stored in the record specified in step S22)).

The risk quantifying section 121, a content C _L of chemicals lot corresponds to the number L of the record specified in step S22, the content of chemicals in all lots of the identified record in step S22 The difference between the average value C _mean and the average value C _mean is calculated as c _L (= C _L −C _mean ).

Next, the risk quantification unit 121 determines the difference c _L between the chemical substance content rate C _L-1 of the lot corresponding to the number L-1 immediately before the number L and the average value C _mean of the content rate. _-1 is specified, and the Durbin-Watson ratio DW is calculated by the following equation (1).

  That is, the content ratio of the chemical substance of the lot corresponding to the number L, the content ratio of the chemical substance of the lot corresponding to the preceding number L-1, and the average value of the chemical substance contents of all the lots And squared the difference between the sum of squares of the differences obtained by subtracting and the difference between the chemical content of the lot corresponding to the number L and the average value of the chemical content of all the lots. The ratio of the added value to the added value is the Durbin-Watson ratio DW.

  Then, the risk quantifying unit 121 determines that there is a positive series correlation when the DW calculated in this way is equal to or less than a threshold value corresponding to a predetermined reliability, that is, a time-series change in content rate. It is determined that there is a high possibility that there was an abnormal behavior.

Next, the risk quantification unit 121 corresponds to the number L as shown in FIG. 11 in the content ratio of the chemical substance determined that there is a high possibility that the time series change of the content ratio has an abnormal behavior. content and C _L lot of chemicals, between the content of C _L-1 chemicals lot corresponding to the previous number L-1, so that the average value C _mean the content is present case, i.e., the change between the content of C _L of chemicals lot corresponding to the numbers L, the content of C _L-1 chemicals lot corresponding to the previous number L-1 When there is a change that crosses the average value C _mean of the content rate, such a change in content rate is specified as an abnormal change in content rate.

Then, the risk quantification unit 121 records either one before or after the abnormal change (in this embodiment, the content ratio C _L after the abnormal change) in order to identify the abnormal content change. The “NG” flag is attached to the abnormal field 111d corresponding to

Here, was calculated "cliff" of content using the Durbin-Watson ratio DW, not limited to such embodiments, for example, the content C _L of chemicals lot corresponds to the number L , if the content of C _L-1 chemicals lot corresponding to the previous number L-1, the difference value between greater than a predetermined value, it is determined that "cliff" May be.

  Next, the “peak” extraction method by the risk quantification unit 121 will be described.

  FIG. 12 shows the chemical substance content rate in the record specified in step S22 as a time series graph using the date stored in the registration date field 111k, and a distribution graph (histogram) for each content rate. ).

  As shown in FIG. 12, when a content rate histogram is created from the content rate time-series graph, a lot with a content rate outside a specific confidence interval has an abnormal change as a “peak” in the histogram. it is conceivable that.

  Specifically, the risk quantification unit 121 calculates a probability density function expressed by equation (2). Here, it is assumed that the probability density function of the content rate estimated from the histogram as shown in FIG. 12 follows a beta distribution having an average and a variance obtained from a sample. Here, it is considered that the probability density function of the content rate follows other distributions such as a normal distribution, but since the content rate is always 0 ppm or more and 100 wt% or less, it is reasonable that the probability density function also has a finite range. It is desirable to apply the beta distribution in view of the fact that the risk can be quantified relatively easily by using the beta distribution.

Note that the coefficients α and β of the beta distribution B (α, β) at this time are expressed as in equation (3), where C _{mean is} the average content rate obtained from the sample and C _var is the variance of the content rate. Is done.

  In this way, the risk quantifying unit 121 can determine the upper limit and the lower limit of the content rate distribution by specifying the beta distribution and setting a specific confidence interval (for example, 99%), and outside the confidence interval. A certain content rate can be specified as having an abnormal change.

  Then, the risk quantifying unit 121 attaches an “NG” flag to the abnormal field 111d of the record corresponding to the content rate having the abnormal change specified in this way.

  In addition, although the peak was specified using the probability density function here, it is not limited to such an aspect, for example, a specific content rate is larger than the predetermined value rather than the average value of a content rate. Or when it is small, you may determine with a peak.

  As described above, the risk quantifying unit 121 performs the abnormality specifying process shown in step S23 (S23).

  Next, the risk quantifying unit 121 determines whether or not the chemical substance identified in step S22 is a predetermined substance (S24). If the chemical substance is a predetermined substance (in S24). Yes) Proceed to step S25, and if it is not a predetermined substance (No in S24), proceed to step S26.

  In step S24, for example, are the chemical substances regulated by the RoHS Directive 6 types (lead, mercury, cadmium 3 elements, hexavalent chromium, polybromobiphenyl (PBB), polybromodiphenyl ether (PBDE))? Determine whether or not. In particular, when the information stored in the component configuration information field 111c of the component attribute table 111a is the output result of the fluorescent X-ray analyzer, only the content rate in element units is output, so three elements of lead, mercury, and cadmium are included. It is normal to be subject to evaluation.

  In step S25, the risk quantification unit 121 performs a management value excess probability calculation process.

  Here, the risk quantification part 121 calculates | requires the probability density function of a content rate using (2) Formula and (3) Formula similarly to step S24. From the distribution B (α, β) at this time, a management value excess probability, which is a probability that the content rate exceeds the management value defined by the RoHS command, is obtained.

  For example, when the chemical substance to be processed in S25 is lead, the management value of lead is 1000 ppm according to the RoHS directive, and therefore the frequency of content exceeding 1000 ppm in the distribution B (α, β) is increased. Then, by dividing by all the frequencies of the distribution B (α, β), the probability of exceeding the management value is calculated.

  Then, the risk quantifying unit 121 stores the management value excess probability thus obtained in the step S management value excess probability field 115d of the management value excess table 115a.

  The risk quantifying unit 121 deletes the lot field 111i, the registration date field 111k, the chemical substance field 111n, the content rate field 111o, and the abnormal field 111d from the manufacturing table 111a shown in FIG. In addition, the management value excess table 115 a is generated in advance by adding the management value excess probability field 115 d and stored in the management value excess information storage area 115.

  In step S26, the processes from step S22 to S25 are repeated for all chemical substances contained in the constituent material specified in step S21.

  Next, the risk quantification unit 121 measures the abnormal behavior occurrence frequency (S27).

  For example, the abnormal change in the content rate specified in step S23 includes a behavior (hereinafter referred to as “irrelevant behavior”) that is not related to the change in the content rate of the component itself, such as poor adjustment of the measuring instrument. It seems to be. Therefore, among the records in which the character string “NG” is stored in the abnormal field 111d of the part attribute table 111a, the records having the same date stored in the registration date field 111k are the third of the whole. If there is one or more, a correction is made to delete the character string “NG” stored in the abnormal field 111d of the record of the date. The record to be corrected at this time is not limited to the record of the component ID and component material that is currently evaluated, but is applied to all data stored in the component attribute table 111a.

  Next, the risk quantification unit 121 quantifies the certification failure risk of the constituent material specified in step S21 (S28).

  First, the risk quantification unit 121 calculates a certification failure risk due to an abnormal change in content rate.

  Specifically, the risk quantifying unit 121 identifies a record in which the character string “NG” is stored in the abnormality field 111d from the component attribute information table 111a, and identifies the component classification field 111f and the supplier field 111g of the identified record. The information that matches the information stored in the manufacturer field 111h, the manufacturing location field 111j, and the component material field 111l is caused by an abnormality from the abnormality cause risk field 114g of the record stored in the corresponding field of the certification failure table 114a. Get risk.

And since the certification failure risk (probability) of the constituent material is considered to be the product of the probability that an abnormal change will occur and the probability of reaching certification failure at that time, the risk quantification unit 121 uses the equation (4). Then, a certification failure risk R ′ _{component material} caused by an abnormal change in the content rate for each _{component material} is calculated.

  Here, i is an identification number in which a serial number is assigned sequentially from 1 for each lot stored in the lot field 111i of the record in which the character string “NG” is stored in the abnormality field 111d from the component attribute information table 111a. (That is, the same part ID, the same part classification, the same supplier, and the same lot of the same manufacturer are assigned one identification number).

  N is the total number of lots stored in the lot field 111i of the part attribute information table 111a, and n is the lot of the record in which the character string “NG” is stored in the abnormal field 111d of the part attribute information table 111a. This is the total number of lots stored in the field 111i.

R _i ′ is information that matches the information stored in the parts classification field 111f, supplier field 111g, manufacturer field 111h, manufacturing place field 111j, and component material field 111l of the record corresponding to the lot with the identification number i. The anomaly-caused risk acquired from the anomaly-caused risk field 114g of the record stored in the corresponding field of the causal risk table 114a.

  Next, the risk quantification unit 121 calculates a certification failure risk due to the management value excess probability.

First, the risk quantifying unit 121 identifies the record in which the constituent material identified in step S21 is stored in the constituent material field 115j of the management value excess table 115a, and stores it in the chemical substance field of the identified record. Each chemical substance is assigned an identification number j as a natural number in order from 1, and a management value excess probability R _j ′ corresponding to the identification number j is obtained.

Then, the risk quantification unit 121 calculates a certification failure risk R ″ _{constituent material} due to the probability of exceeding the management value for each constituent material by the equation (5).

  Note that m is the total number of chemical substances stored in the chemical substance field 115l of the management value excess table 115a corresponding to the constituent material specified in step S21.

  And the risk quantification part 121 calculates the certification failure risk for every lot by (6) Formula from the two types of certification failure risk computed as mentioned above.

  Then, the risk quantification unit 121 creates a new record in the evaluation result table 116a, the component ID identified in step S20 in the component ID field 116b, the component material identified in step S21 in the component material field 116c, ( 6) The certification failure risk for each lot calculated by the equation (6) is stored in the certification failure risk field 116d.

  Next, the risk quantification unit 121 repeats the processes from Steps S21 to S28 for all the constituent materials included in the part ID identified in Step S20 (S29).

  Then, the risk quantifying unit 121 repeatedly performs the processing from step S20 to S29 for the parts corresponding to all the part IDs stored in the part ID field 111e of the part attribute table 111a (S30).

  FIG. 13 is a flowchart of the analysis prioritizing process in step S11 in FIG.

  First, the analysis priority determination unit 122 receives an input of a component ID list having a plurality of component IDs for specifying components to be analyzed and an analysis condition via the input unit 130 (S40).

  For example, the analysis priority order determination unit 122 outputs an input screen 160 as shown in FIG. 14 (schematic diagram of the input screen 160) to the output unit 140 and receives input of necessary information via the input unit 130.

  The input screen 160 includes a part ID list input area 160a, a reference instruction input area 160b, an analysis capability input area 160c, a minimum inspection frequency unit input area 160d, a minimum inspection frequency input area 160e, and an evaluation start instruction input area 160f. And a cancel instruction input area 160g.

  The component ID list input area 160a accepts input of information specifying a component ID list that specifies component IDs for ranking analysis.

  In this embodiment, a component ID list file in which a list of component IDs is registered in a predetermined format is stored in the storage unit 110 in advance, and an execution instruction specifying the reference instruction input area 160b via the input unit 130 is performed. By specifying the component ID list file stored in the storage unit 110, a list of component IDs is input.

  It is also possible to directly input information for specifying a component ID in the component ID list input area 160a.

  The analysis capability input area 160c receives input of information for specifying the analysis capability of a device that performs analysis, for example, an X-ray fluorescence analyzer or an inductively coupled plasma analyzer. Here, in the present embodiment, input of information specifying an analysis possible portion (number of times) per unit time (here, one day) of the analyzer is accepted.

  The minimum inspection frequency unit input area 160d accepts input of information specifying the unit of the number of inspections input to the later-described minimum inspection frequency input area 160e for the analysis target portion (component material).

  Here, in this embodiment, the period (here, one month) or the number of lots (here, 10 lots) can be selected.

  The minimum inspection frequency input area 160e stores information for specifying the minimum number of times that inspection must be performed in the unit specified in the minimum inspection frequency unit input area 160d.

  When an input of necessary information is received in the input area described above and an execution instruction specifying the evaluation start instruction input area 160f is input via the input unit 130, the analysis priority order determination unit 122 will be described later. The process of step S41 is performed.

  On the other hand, when an execution instruction specifying the cancel instruction input area 160g is input via the input unit 130, the information input to the input area described above is canceled (deleted).

  In step S41, the analysis priority order determination unit 122 extracts one component ID that has not been processed in step S41 and thereafter from the component ID list input in step S40.

  Next, the analysis priority order determination unit 122 identifies the record in which the component ID extracted in step S41 is stored in the component ID field 116b from the evaluation result table 116, and enters the certification failure risk field 116d of the identified record. The stored certification failure risk is acquired (S42).

  Next, the analysis priority determination part 122 calculates the certification failure risk per unit period (S43).

  Specifically, the analysis priority determining unit 122 identifies the record in which the component ID extracted in step S41 is stored in the component ID field 116b from the manufacturing table 112a, and refers to the delivery date field 112g of the identified record. By doing this, the number of lots (number of records) in a predetermined unit period (for example, the period from the processing date in which step S43 is processed in the analysis priority determining unit 122 to one month ago) is determined for each constituent material. The certification failure risk for each constituent material in the unit period is calculated by calculating and multiplying the certification failure risk acquired in step S42 by the calculated number of lots for each constituent material.

  Note that the analysis priority order determination unit 122 corresponds to the certification failure risk for each constituent material in the unit period calculated as described above to the part ID extracted in step S41 of the evaluation result table 116a and the calculated constituent material. Stored in the risk field 116e per unit time of the record.

  Then, the analysis priority order determination unit 122 repeats the processing of steps S41 to S43 for all the component IDs included in the component ID list received in step S40 (S44).

  Next, the analysis priority order determination unit 122 identifies the record corresponding to the component ID included in the component ID list received in step S40 from the evaluation result table 116a, and the risk per unit time of the identified record. The certification failure risk in the unit period stored in the field 116e is extracted, and the combination of the component ID and the constituent material is ranked so that the risk is ranked in descending order (from the highest value) ( S45).

  Next, the analysis priority order determination unit 122 assigns the analysis frequency so that the certification failure risk for all parts is minimized (S46).

  Specifically, the analysis priority determining unit 122 calculates the analysis ability (analysable location) in the unit period for which the certification failure risk is calculated in step 43 from the value specified in the analysis ability input area 160c (here, , Input value x number of days in unit period).

  Then, the analysis priority order determination unit 122 sequentially satisfies the minimum inspection frequency per place received as an analysis condition in step S40 in descending order of the combination of the component ID and the constituent material in step S45. Allocate analytical capabilities in unit periods.

  Specifically, when the analysis capability in the unit period is “600”, first, the analysis capability (number of times) satisfying the minimum inspection frequency is assigned to the combination of the part ID and the constituent material that is ranked highest in step S45. . For example, when “one month” is input in the minimum inspection frequency unit input area 160d and “20” is input in the minimum inspection frequency input area 160e, the unit period in step S43 is also “one month”. Since all of the minimum inspection frequency “20” can be allocated from the analysis capability “600”, all of these are allocated, and the remaining analysis capability is “600−20 = 580”.

  Then, the remaining analysis ability is applied to the combination of the part ID and the constituent material of the next order, and the process of performing the allocation is repeated until the analysis ability is exhausted or the combination of the part ID and the constituent material to be assigned is eliminated. Do.

  When the period input in the minimum inspection frequency unit input area 160d is different from the unit period in step S43, the unit period in step S43 is divided by the period input in the minimum inspection frequency unit input area 160d. A value obtained by multiplying the value input in the minimum inspection frequency input area 160e is assigned to the combination of the component ID and the constituent material as the minimum inspection frequency.

  Further, when the number of lots is input in the minimum inspection frequency unit input area 160d, a value obtained by multiplying the number of lots for each component specified in step S43 by the number of lots specified in the minimum inspection frequency unit input area 160d is obtained. A value obtained by multiplying the value input in the minimum inspection frequency input area 160e is assigned to the combination of the component ID and the constituent material as the minimum inspection frequency.

  As described above, even if the analysis ability is assigned to all combinations of the part ID and the constituent material, if there is still a remaining part, the step is performed in descending order of the combination of the part ID and the constituent material in step S45. The process of allocating a value obtained by subtracting the minimum inspection frequency allocated to the combination of the part ID and the constituent material from the number of lots specified for each part in S43, from the analysis ability, until the analysis ability in the unit period disappears, or Repeat until there are no more combinations of component IDs and constituent materials to be allocated.

  Then, as described above, the analysis priority order determination unit 122 stores the analysis capability allocated to the combination of the part ID and the constituent material in the corresponding recommended inspection number field 116f of the evaluation result table 116a.

  Next, the analysis priority order determination unit 122 sets the priority given in step S45 and the analysis capability assigned to the combination of the part ID and the constituent material performed in step S46 to a predetermined output screen 161, and outputs the output unit The process of outputting to 140 is performed (S47).

  FIG. 15 is a schematic diagram of the output screen 161.

  As shown in the figure, the output screen 161 has a ranking field 161a, a component ID field 161b, a constituent material field 161c, a risk field 161d, and a recommended number of inspections field 161e.

  The rank field 161a stores information for specifying the analysis priority calculated in step S45. Here, in this embodiment, it arrange | positions so that it may be located in the upper direction of the output screen 161 in an order from a high analysis priority, However, It is not necessarily limited to such an aspect.

  The component ID field 161b stores information for identifying a component ID corresponding to the rank specified in the rank field 161a.

  The component material field 161c stores information for identifying the component material corresponding to the rank specified in the rank field 161a.

  The risk field 161d stores information stored in the risk field 116e per unit period of the evaluation result table 116a corresponding to the component ID specified in the component ID field 161b and the component material specified in the component material field 161c. Is done.

  In the recommended inspection frequency field 161e, information stored in the recommended inspection frequency field 116f of the evaluation result table 116a corresponding to the component ID specified in the component ID field 161b and the component material specified in the component material field 161c is stored. Stored.

  FIG. 16 is a flowchart showing the analysis necessity determination process in step S12 of FIG.

  First, the analysis necessity determination unit 123 receives an input of a component ID via the input unit 130 (S50).

  Next, the analysis necessity determination unit 123 acquires the recommended number of inspections for the component ID received in step S50 from the recommended number of inspections field 116f of the evaluation result table 116a (S51). In addition, when there are a plurality of constituent materials in the component ID, the recommended number of inspections is acquired.

  Next, the analysis necessity determination unit 123 determines the lot number (number of records) in the unit period of the component ID (in the present embodiment, the past one month) received in step S50 as the lot in the component attribute table 111a. It is calculated from the field 111i (S52).

  That is, since the record stored in the component attribute table 111a has been analyzed by, for example, a fluorescent X-ray analyzer or an inductively coupled plasma analyzer, the processing in step S52 is performed by the component ID in the unit period. This indicates the number of analysis (inspection) of the specified part.

  Then, the analysis necessity determination unit 123 determines whether it is necessary to analyze the component specified by the component ID input in step S50 (S53).

  Specifically, the analysis necessity determination unit 123 compares the recommended number of inspections acquired in step S51 with the number of analysis lots calculated in step S52, and the recommended number of inspections is larger than the number of analysis lots. If it is determined that inspection is necessary, the process proceeds to step S54. On the other hand, if the recommended number of inspections is equal to or smaller than the number of analysis lots, it is determined that inspection is not necessary, and the process proceeds to step S55. When the recommended number of inspections for each of the plurality of constituent materials is acquired in step S51, if there is at least one recommended number of inspections compared to the number of analysis lots, it is determined that inspection is necessary. Proceed to S54.

  In step S54, the analysis necessity determination unit 123 acquires the component classification corresponding to the component ID acquired in step S50 from the component classification field 111f of the component attribute table 111a, and corresponds to the component classification acquired from the analysis know-how table 113a. The record to be identified is specified, and the part, remark, and photograph stored in the part field 113c, the remarks field 113d, and the photograph field 113e of the specified record are acquired (S54).

  Next, the analysis necessity determination unit 123 generates an output screen 162 and outputs it to the output unit 140 (S55).

  FIG. 17 is a schematic diagram of the output screen 162.

  As illustrated, the output screen 162 includes a part ID display area 162a, an analysis recommended site presence / absence display area 162b, an analysis-required constituent material display area 162c, an analysis-unnecessary constituent material display area 162d, and an analysis know-how information display area 162e. And comprising.

  In the component ID display area 162a, information for identifying the component ID received in step S50 is displayed.

  In the analysis recommended part presence / absence display area 162b, if it is determined in step S53 that the analysis is necessary, a message indicating that there is an analysis recommended part is displayed, for example, a character string “with analysis recommended part” is displayed. If it is determined in S53 that analysis is not necessary, a message indicating that there is no analysis recommended site, for example, a character string “no analysis recommended site” is displayed.

  In the analysis-required constituent material display area 162c, information for specifying the constituent material determined to be analyzed in step S53 is displayed. If there is no constituent material determined to be analyzed in step S53, this display area is not displayed.

  In the analysis unnecessary constituent material display area 162d, information for specifying the constituent material determined to be unnecessary in step S53 is displayed. Note that this display area is not displayed when there is no constituent material determined to be unnecessary in step S53.

  In the analysis know-how information display area 162e, information specifying the part, remarks, and photograph acquired in step S54 is displayed. If there is no such information, this display area is not displayed.

  In the embodiment described above, the part attribute table 111a, the manufacturing table 112a, and the analysis know-how table 113a have been described on the premise that they are stored in the storage unit 110 of the analysis inspection support apparatus 100. For example, as in the communication system shown in FIG. 18 (schematic diagram of the communication system), a storage apparatus 170 capable of transmitting and receiving information via the network 171 and the analysis test support apparatus 100 is provided. In addition, information stored in the component attribute table 111a, the manufacturing table 112a, and the analysis know-how table 113a is accumulated in the storage device 170 in a timely manner, and is necessary when performing abnormally explained processing in the analysis inspection support device 100. Information is acquired from the storage device 170 and the component attribute table 11a, it may be performed and the processing is stored in the prepared tables 112a and analysis knowhow table 113a.

  In the embodiment described above, the process of calculating the certification failure risk for the combination of the component ID and the constituent material has been described in the flowchart shown in FIG. It is also possible to calculate the certification failure risk for each component specified by the component ID.

In this case, the processing of step S27 and step S28 may be performed after step S29 of FIG. At this time, the total number of lots of the component ID for calculating the certification failure risk is N, the number of abnormal parts determined is n, and each abnormality-caused risk is represented by R _i ′ (i = 1,..., N). Then, the certification failure risk per lot due to the lot determined to be abnormal in the component ID is obtained by the equation (7).

Further, the probability of exceeding the control value in the constituent material k (k = 1,..., L) and the chemical substance j (j = 1,..., L) included in the component ID is R ″ _{k, j} . At this time, the probability of exceeding the management value of the component specified by the component ID is obtained by the equation (8).

  Then, regarding the part specified by this part ID, the certification failure risk of the next lot is obtained by equation (9).

  However, the risk of failing certification is usually significantly different depending on the constituent materials. In addition, since analysis devices used for normal environmental quality assurance operations such as fluorescent X-ray analyzers can perform non-destructive analysis, high-risk component materials and low-risk component materials are identified even for parts identified by the same part ID. It is possible to operate by classifying the former and analyzing only the former. Therefore, the present invention recommends a method of calculating the certification failure risk for each constituent material in order to realize an efficient quality assurance operation.

  Moreover, in embodiment described above, although the risk regarding components was quantified, it is not limited to such an aspect, For example, this invention is also applicable to foodstuffs.

  In this case, instead of the part attribute table 111a, the food having the parts management information field as a food management information field storing food management information and the parts configuration information field as a food composition information field storing food configuration information is used. An attribute table may be used.

  Further, in food products, the information to be inspected may be information other than the concentration of chemical substances such as temperature and humidity. However, there is no difference between the evaluation method and the first embodiment.

  Furthermore, in food products, not only the upper limit value but also the lower limit value may be set as the inspection object information, such as allergen concentration and nutrient concentration, as in the case of heavy metals. Therefore, the risk quantification unit 121 described above mainly calculates the risk exceeding the upper limit value, but here, the risk deviating from a certain section is calculated. However, the evaluation method can be calculated with the same logic as in the above-described embodiment, both in the case of risk calculation exceeding the upper limit value and in the case of risk calculation exceeding the lower limit value.
