Description

  The present invention relates to an environmental information aggregation method and an environmental information aggregation device for evaluating environmental information of products, and in particular, environmental information obtained from a supplier of procurement items such as parts and materials (hereinafter referred to as a supplier) in units of products. It is related to the technology to count.

  In recent years, mainly in Europe, environmental regulations for products have been strengthened. For example, regulations concerning substances contained in products include the RoHS Directive and REACH regulations. The former is a regulation that prohibits the content of a specific substance in a product from exceeding a certain level, and the latter is the transmission of information about a substance when the substance contained in a product sold in Europe exceeds a certain amount. And regulations that require registration.

  In order to comply with such environmental regulations, it is necessary to grasp the environmental information of the product at the design stage and take measures to satisfy the requirements of the regulations. For example, in the RoHS directive, it is necessary to grasp the type and amount of a substance contained in a part constituting a product, and to replace the part when the regulation value is not satisfied. Further, according to the REACH rule, it is necessary to determine whether or not a substance of very high concern (SVHC: Substance of Very High Concern) exceeds a certain amount with respect to the product weight.

  In order to make such a determination, it is necessary to develop the product into parts and materials to grasp environmental information. However, since electrical and electronic products and machine products are composed of many parts and materials, it is difficult for manufacturers to measure environmental information for all parts and materials themselves.

  For this reason, many manufacturers obtain environmental information on purchased items such as parts and materials from suppliers, and tabulate them for each product.

  As a method for counting environmental information, Japanese Patent No. 3931689 (Patent Document 1) includes a method for totaling environmental information of products by matching environmental information obtained from a supplier with a parts list of products. It is shown. By using this system, manufacturers can automatically collect hundreds to thousands of environmental information, and can easily check the status of compliance with regulations.

  However, in such a method of obtaining environmental information from a supplier, there is a problem in that environmental information cannot be obtained by a later supplier if information transmission is delayed in the middle of a product supply chain by a plurality of suppliers.

  For this reason, it is difficult for manufacturers at the end of the supply chain to obtain environmental information on all procured products at the initial stage of design. For this reason, measures such as in-house measurement are taken, but if it is found that the product does not comply with the regulations in the latter half of the design, there is a problem that rework occurs and the design period is prolonged.

  Therefore, conventionally, there has been a method for analogizing environmental information that cannot be obtained from a supplier, as described in JP-A-2006-277426 (Patent Document 2), by statistically processing environmental information of similar parts. .

Japanese Patent No. 3931689 JP 2006-277426 A

  As described above, electrical and electronic products, mechanical products, and the like are products positioned at the end of the supply chain, and the supply chain of procured products is diverse. For example, semiconductor integrated circuits and electronic components are manufactured by processing materials, so the supply chain is relatively short. Conversely, a unit product such as a power supply board made by assembling these components has a relatively long supply chain.

  Here, procurement items with a long supply chain, such as unit products, have a problem in that it is difficult to obtain environmental information because the number of times environmental information is transmitted between manufacturers compared to procurement items with a short supply chain. .

  The one described in Patent Document 2 is effective for procured products with environmental information on similar parts, but as described above, it is necessary for statistical processing for procured products with a long supply chain or parts with a small procurement amount. It may not be applicable because there is not enough data.

  In addition, when the estimated value is included in the environmental information tabulation result of the product, it was necessary to grasp the probability (risk) of deviating from the regulation value due to the estimation error in order to determine the necessity of countermeasures. .

  Accordingly, an object of the present invention is to provide an environmental information tabulation method and a tabulation apparatus capable of accurately estimating environmental information of similar parts or parts with a small amount of procurement and evaluating the risk that the environmental information of a product deviates from the regulation value. It is to provide.

  The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

  Of the inventions disclosed in the present application, the outline of typical ones will be briefly described as follows.

  In other words, if there is no environmental information of the procurement item, the outline of the representative thing is to grasp the component parts of the procurement item using a virtual parts table that describes the parent-child relationship of the parts in advance by the parts category, The environmental information of the component parts is estimated by using the environmental information of the similar parts, and the environmental information of the procured products is totaled by counting the analogy results according to a virtual parts table.

  The effects obtained by typical ones of the inventions disclosed in the present application will be briefly described as follows.

  In other words, the effects obtained by representative products are similar to those of components and materials that are difficult to obtain environmental information, even for parts and materials that make up the procurement items, even for parts that are not procured. By estimating the environmental information using the parts and estimating the environmental information of the procured product as the sum of the environmental information of the component parts and constituent materials, the environmental information of the procured product can be estimated with high probability.

  As a result, it is possible to estimate environmental information of more procured products at an early stage of design, and it is possible to prevent design delay due to rework.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted.

  In the present embodiment, the content of chemical substances is taken as an example of environmental information, but other environmental information such as the amount of carbon dioxide generated can also be aggregated in the same manner.

  With reference to FIG. 1, the configuration of an environment information totaling apparatus according to an embodiment of the present invention will be described. FIG. 1 is a configuration diagram showing a configuration of an environment information totaling apparatus according to an embodiment of the present invention.

  In FIG. 1, an environment information totaling device includes an input device 101 that inputs a command to the control device, a display device 102 that displays a totaling result of environmental information, and a data storage device 103 that stores input data necessary for totaling environmental information. The control unit 104 receives commands from the input device 101, collects data from the data storage device 103, and totals environmental information of products.

  Here, the input device 101 is a keyboard or mouse used as an input device in a normal personal computer or the like, and the display device 102 is a CRT (Cathode Ray Tube), an LCD (Liquid Crystal Display), or the like. Further, the data storage device 103 is a data receiving device via a disk drive device such as a magnetic recording device connected to the control device 104 or a network such as a LAN (Local Area Network), and includes regulation information 1051 and product components. A table 1052, a parts list 106 of procurement items, which is a virtual parts table, environment information 107 of procurement items, and survey information 108 are recorded. These pieces of information may be recorded on one recording device or may be distributed and recorded on a plurality of recording devices.

  The control device 104 includes an arithmetic processing unit and a memory (not shown). The arithmetic device and the memory are integrated, and the environment information search unit 109 for the procured product and the parts table search unit 110 for the procured product are combined. , Terminal part environment information estimation unit 111, procurement product environment information estimation unit 112, survey information search unit 113, product environment information totaling unit 114, and risk evaluation unit 115. More specifically, each processing unit indicated by 109 to 115 in FIG. 1 is a program stored in the memory of the control device 104 and executed by the arithmetic processing device.

  Here, referring to FIG. 2, an environmental information totaling method using a parts table as a basis of the environmental information totaling apparatus according to the embodiment of the present invention will be described. FIG. 2 is a conceptual diagram of an environmental information totaling method using a parts table as a basis of the environmental information totaling apparatus according to an embodiment of the present invention.

  In FIG. 2, the parts list of the product shows the procurement items constituting the product. FIG. 2 shows an example in which a server is taken up as a product, and shows that the server includes a casing, a hard disk, a motherboard, and a covered electric wire.

  The environmental information 107 of the procurement item is a database in which environmental information of the procurement item is recorded. Here, SVHC (Substances of Very High Concern) is a general term for chemical substances specified by the REACH rule, but in this embodiment, it is used as a notation indicating a chemical substance.

  The example shown in FIG. 2 indicates that SVHC is contained in the housing, the hard disk, the motherboard, and the covered electric wire, respectively, at 0 mg, 7.5 mg, 7.7 mg, and 1 mg.

  The environmental information of a product is obtained by matching these two pieces of information for each part and totaling the entire product. In the example shown in FIG. 2, the SVHC included in the server is 16.2 mg (0 + 7.5 + 7.7 + 1).

  In the present embodiment, as shown in FIG. 2, not only when all the procured products are grasped, but also when the information on the procured products cannot be obtained from the supplier, the product bill of materials is prepared in advance. By providing a bill of materials 106 for virtually procured items, environmental information can be aggregated.

  Next, referring to FIG. 3 to FIG. 9, an intermediate file for recording a specific example of each data stored in the data storage device of the environmental information totaling device according to one embodiment of the present invention and a result during the environmental information totaling A specific example will be described. 3 is a diagram showing a specific example of regulatory information, FIG. 4 and FIG. 5 are diagrams showing a specific example of a parts bill of products, FIG. 6 is a diagram showing a concrete example of a parts bill of procured products, and FIG. FIG. 8 is a diagram showing a concrete example, FIG. 8 is a diagram showing a concrete example of survey information, and FIG. 9 is a diagram showing a concrete example of an intermediate file that records the results during the compilation of environmental information.

  In FIG. 3, the restriction information 1051 records the information type and restriction value necessary for determining conformity to the restriction for each restriction name. In the example shown in FIG. 3, SVHC information is required for the REACH rule, and the regulation value is 0.1% with respect to the product weight.

  4 and 5, the product parts table 1052 includes two files, a file 301 indicating a parent-child relationship of parts and a file 401 indicating attributes of each part.

  In the file 301 showing the parent-child relationship of parts shown in FIG. 4, “part number” indicates a number uniquely assigned to the procured product, such as a drawing number corresponding to the procured product or a product model number set by the supplier. . One line in FIG. 4 indicates the parent-child relationship of the parts, and “number” indicates the number of child parts included in the parent part.

  That is, FIG. 4 shows that the product P00001 is composed of four types of parts A00001 to A00004, and each part is used one by one.

  In the file 401 showing the component attribute information shown in FIG. 5, the component attribute information is information indicating the procurement source and specifications of the component, and is recorded for each component number. The example which showed only the category of is shown.

  That is, FIG. 5 shows that each of the parts numbers A00001 to A00004 is a casing, a hard disk, a motherboard, and a covered electric wire.

  In FIG. 6, a parts list 106 of the procured goods is virtual information for estimating the environmental information of the procured goods from the environmental information of the components and materials. Although it is desirable to obtain the bill of materials 106 from the supplier, it is not possible to obtain all the procurement items. For this reason, alternatives are necessary for procurement items that are not available.

  Therefore, in the present embodiment, it is assumed that the same type of procured product has similar components and materials, and a parts table created for each type of procured product (hereinafter referred to as a substitute parts table) is used. The parts list for replacement is created by, for example, investigating a plurality of parts configurations of the same type of procured product, for example, by disassembling the procured product or the parts table obtained from the supplier, and summing them up.

  In addition, the part list for replacement cannot be limited to the part (parent part) that is the citation source in the actual part list, and the part number cannot be specified because the child part is not an in-house part. Describe using the component category, not the component number.

  For example, in the example shown in FIG. 6, the “motherboard” is composed of “printed circuit boards” and “electronic components”, and the number of each component is one “printed circuit board” as a result of examining a plurality of “motherboards”. It shows that the number of “electronic components” can be ten.

  Here, it is necessary to set the number of component parts and the number of parts in consideration of risks in the aggregation of environmental information of products. For example, in order to avoid the risk that the content of chemical substances is underestimated, a method of setting the maximum value obtained from the survey results can be considered.

  In FIG. 7, the environmental information 107 of the procured product is information obtained from the supplier of the procured product, and records the component category, the contained substance, the content, the weight of the component, etc. for each “part number”.

  In the example illustrated in FIG. 7, the procured product having the part number A00001 has the part category “housing”, does not include SVHC (0 ppm), and indicates that the part weight is 1.0 kg.

  The procured product with the part number A00002 is “hard disk”, but “hard disk” includes other parts with part numbers A00011 and A00012. For these parts, SVHC information is provided by the supplier, which is 10 ppm and 20 ppm, respectively. Similarly, there are a plurality of components for the component categories “printed circuit board” and “electronic component”, and SVCH information is provided from the supplier.

  The symbol (-) shown in the "substance" and "content" sections of the procured products with part numbers A00002 to A00004 indicates that such chemical substance information is not available from the supplier.

  In FIG. 8, survey information 108 is information used to set environmental information 107 of a procurement item for which environmental information cannot be obtained from the supplier and the parts list 106 of the procurement item does not exist, and is included in the procurement item. Record the results of in-house measurement of substances and general information shown in literature.

  The survey information 108 describes at least the name of the contained substance and the content or content rate for each part category. In the example shown in FIG. 8, it is shown that SVHC is contained in the covered electric wire, the adhesive, and the lubricant at 10 ppm, 1 ppm, and 5 ppm.

  In the present embodiment, an estimated value is used for a procured product that has no environmental information obtained from a supplier, and an intermediate file 801 that records a result during the aggregation of environmental information using the estimated value is generated.

  The intermediate file 801 may be stored in the data storage device 103 or may be held as the intermediate file 801 in the control device 104 when the environmental information is aggregated.

  In FIG. 9, the intermediate file 801 records information such as the content as an estimation result in addition to the estimation method and the contained substance name for each part number. In the example illustrated in FIG. 9, a part whose “estimation method” is “determined” indicates that there is environmental information obtained from the supplier.

  “Estimation (parts)” is an analogy from similar parts, “Estimation (units)” is an estimation using the parts table 106 of the procured product, and “Estimation (survey)” is environmental information using the investigation information 108. Indicates that is set.

  Here, when the environmental information is estimated from similar parts or is estimated using the parts list 106 of the procured product, the result of the average value and the standard deviation is recorded as the environmental information of the procured product. If the environmental information can be obtained from the supplier, the environmental information can be uniquely identified, and the result is recorded in the average value column.

  Next, with reference to FIG. 10, the environmental information totaling process of the environmental information totaling apparatus according to an embodiment of the present invention will be described. FIG. 10 is a flowchart showing environmental information totaling processing of the environmental information totaling apparatus according to the embodiment of the present invention. Regulation information 1051, product parts table 1052, procurement parts table 106, and procurement environment information 107 shows a process of collecting environmental information using the survey information 108.

  When the environmental information totalizing apparatus inputs a product name and a regulation name via the input device 101 and receives an evaluation execution command, it performs the following processing.

  First, the input product name and restriction name are read (S900), and the specified product name configuration information file 301 and the part attribute file 401 are read from the product parts table 1052 of the data storage device 103 (S901).

  Next, the lowest layer part is searched in the configuration information file 301 of the product, and the part number of the procured product used for the product is specified. The environment information 107 is searched using the part number acquired in this way, and the environment information of the procured product is acquired (S902). This processing is performed by the environment information retrieval unit 109 of the procured product.

  In this processing step S902, when the data corresponding to the procured product exists in the environmental information 107 of the procured product, the substance name and content are acquired, the environmental information of the component is determined, and recorded in the intermediate file 801. (S910). At this time, the estimation method of the environmental information is “confirmed”. In the products shown in FIGS. 4 and 5, the “casing” having the part number A00001 corresponds to this processing flow.

  On the other hand, when there is no data corresponding to the environmental information 107 in the processing step S902, an estimated value is used for the environmental information of the procured product.

  There are three types of environmental information estimation methods used in the present embodiment: a method of inferring from environmental information of similar parts, a method of estimating using a parts list 106 of procurement items, and a method of setting using survey information 108. There are, however, applied in order from the method with the highest accuracy. In this embodiment, an example applied in the above order will be described.

  The analogy process (S903) using the environmental information of similar parts is performed by the following process.

  First, the category of the component is acquired from the component attribute file 401, and data matching the acquired category is searched from the environment information 107 of the procured product. When a plurality of corresponding data is retrieved from the environmental information 107 of the procured product, the chemical substance and content data of all retrieved parts are acquired, and the average value and standard deviation are obtained (S906), and an intermediate file is obtained. It records in 801 (S908).

  At this time, the estimation method of the environment information is “estimation (part)”. In the products shown in FIG. 4 and FIG. 5, the “hard disk” having the part number A00002 corresponds to this processing flow. This process is performed by the environmental information estimation unit 111 of the end part.

  Next, in processing step S903, when data of the same part category as the procured product cannot be retrieved from the environmental information 107 of the procured product, estimation using the parts table 106 of the procured product is performed (S904).

  Hereinafter, the processing content of the environmental information estimation using the parts list 106 of the procurement item will be described.

  First, the component category of the procured product is acquired from the component attribute file 401, and data with the same category is searched from “parent component” in the component table 106 of the procured product. If a matching category is found here, the component table 106 of the procured product is referred to, and the category of the child component is acquired. This process is performed by the parts list search unit 110 of the procured product.

  After the procured product is developed into parts and materials by the above processing, environmental information of the parts and the materials is estimated.

  The estimation of the environmental information is performed by the same process as in process step S903 (S905). In other words, a procurement item having the same category as the part or the material is searched from the environmental information 107, and the chemical substance and content data are acquired for all the searched parts.

  Next, an average value and a standard deviation are obtained using the acquired chemical substance data (S906), and the calculation result is recorded in the intermediate file 801 (S909).

  At this time, the environment information estimation method is “estimation (unit)”. In the products shown in FIGS. 4 and 5, the “motherboard” having a part number A00003 corresponds to this processing flow. This process is performed by the environment information estimation unit 112 of the procured product.

  Finally, in processing step S904, the survey information 108 is searched for the procured product for which the parts list 106 of the procured product could not be searched. The search of the survey information 108 is performed by acquiring the component category of the component from the component attribute file 401 and determining that it matches the category of the survey information 108 (S907).

  When the survey information 108 is retrieved, the substance name and content of the corresponding part are acquired and recorded in the intermediate file 801 (S911).

  At this time, the environment information estimation method is “survey information”. In the products shown in FIGS. 4 and 5, “covered electric wire” having a part number A00004 corresponds to this processing flow. This process is performed by the survey information search unit 113.

  Next, referring to the intermediate file 801 created by the processing of S901 to S911, the environmental information of the product is totaled (S912).

Here, the environmental information of the product is calculated taking into account that the environmental information of each purchased product is obtained in the form of a statistical distribution. When the environmental information of the product follows a normal distribution, the average and variance as parameters are obtained by the following (Equation 1) and (Equation 2).
(Formula 1)
Average value = Σ {[Confirmed value] + [Average value of estimation (part)] + [Average value of estimation (unit)] + [Average value of estimation (survey)]}
(Formula 2)
Variance = [Standard deviation of estimation (component)] ² + [Standard deviation of estimation (unit)] ²
Next, the restriction value corresponding to the restriction name designated in step S900 is read from restriction information 1051, and the environmental information of the product calculated in step S912 is compared to make a restriction determination (S913). For example, when the result of (Equation 1) is less than or equal to the regulation value, the regulation judgment is “regulatory conformance”, and conversely, when the result is greater than or equal to the regulation value, “regulation nonconformity”. This process is performed by the product environmental information totaling unit 114.

  Further, the probability (risk) that the environmental information of the product exceeds the regulation value is calculated by comparing the environmental information of the product obtained in step S912 with the regulation value (S914). This process is performed by the risk evaluation unit 115.

  Next, the risk evaluation process in process step S914 in FIG. 10 will be described with reference to FIGS. FIG. 11 is a flowchart showing the risk evaluation process in step S914 of FIG. 10, and FIG. 12 is an explanatory diagram for explaining the risk evaluation process of the environmental information totaling apparatus according to the embodiment of the present invention.

  First, the risk evaluation unit 115 reads the regulation value of the legal regulation specified in the processing step S900 of FIG. 10 from the regulation information 1051 (S9141), and based on the parameters obtained in the processing step S912 of FIG. The statistical distribution of the environmental information is estimated (S9142).

Next, the control value is compared with the distribution, and the probability that the environmental information satisfies the following (Equation 3) is calculated (S9143).
(Formula 3)
Environmental Information> Regulated Value The distribution in processing step S9142 is a distribution as shown in FIG. 12, the horizontal axis of FIG. 12 is the environmental information, and in this embodiment is the SVHC content. The distribution in FIG. 12 is the environmental information of the product obtained in step S912. The probability of satisfying the above (Equation 3) can be obtained as the area of the region illustrated as the risk in FIG.

  Then, the calculation result in S9143 is displayed as a risk on the display device 102 (S9144).

  In FIG. 13, the total result 1102 of the environmental information includes, in addition to the total result 1104 of the chemical substances for the entire product, which is the result of the processing step S912 in FIG. Display the summary results.

  In the example shown in FIG. 13, the total value 1105 for the fixed amount, the total value 1106 by analogy using similar parts, the total value 1107 by estimation using the parts list of the procured items, and the estimated value 1108 using survey information are individually obtained. The displayed example is shown.

  Further, the legal compliance determination result 1103 is obtained by dividing the total SVHC content recorded in the SVHC content intermediate file 801 necessary for compliance determination by the product weight, and is displayed in step S913. Displays the result of compliance with the laws and regulations determined by.

  In the example shown in FIG. 13, the SVHC content in the product is 8.5 ppm (0.00085%), which is below the REACH regulation value (0.1%), indicating that it conforms to the regulation. ing.

  Further, the risk evaluation result 1109 is displayed as a result of the processing step S914 in FIG. By displaying the risk in this way, the user of the environmental information totaling apparatus can determine the necessity of countermeasures in consideration of the estimated risk.
