[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the content of chemical substances contained in products in laws and regulations concerning customers' chemical substances at the time of production, use and disposal of products.
Regarding how to verify compliance.

[0002]

2. Description of the Related Art Environmental problems have become serious year by year, and regulations on chemical substances have been strengthened by the nation, and it has become essential for manufacturers as well to fulfill their social responsibility to prevent environmental pollution. However, with regard to parts that make up products other than those that are produced in-house, especially the parts that are procured from other companies of the manufacturer that is the supplier, and the substances contained in the material, the purchasing company grasps the detailed chemical composition It was difficult to do so due to the trade secret wall of the supplier. However, if the legal regulations are not observed, the product itself cannot be sold to consumers, and the manufacturer of parts, which is the supplier, discloses the chemical substances contained in parts.

Even so, the number of parts of a product is enormous, and it is practically difficult for a certain design department or individual designer to collect and manage the data and comply with the regulations.

[0004]

[Problems to be Solved by the Invention] On a daily basis, the design department or the designer individually collects and manages regulatory information such as laws and regulations and information on chemical substances contained in parts, compares them, and compares them to determine the amount of chemical substances. Understanding and designing a product is difficult in terms of processing man-hours. Moreover, there is a risk that the prohibited substances will be mistakenly used in the product. The present invention facilitates the work difficult for the design department or the designer by utilizing the data prepared on the computer and the matching processing function, and complies with the social responsibility as the manufacturer. It is to be able to do it. It is also to provide a means for responding to inquiries from the user regarding the harmfulness of the chemical substances in the contents during use or disposal of the product.

[0005]

According to the present invention, a component data storage unit that stores all contents of components used in a product, a supplier of a component stored in the component data storage unit, and which product is the supplier are the products. It is specified in the parts supplier data storage section that stores uniquely identified management numbers, etc., the part hazardous substance data storage section that stores the contents of chemical substances contained in parts, the legal regulations and the safety standards specified by customers. There is a database that can store four types of data in the regulated substance data storage unit that stores the chemical substances to be searched, and one control code is set for each chemical substance to identify the chemical substance. The specified control code is used in common for both the hazardous substance data storage part for parts and the regulated substance data storage part for laws and regulations so that both chemical substances can be uniquely specified, and the data for parts is stored from the part data storage part. Collect and collect the parts manufacturer and product from the parts delivery maker data storage part using the collected parts data, and use the collected parts maker and product data from the parts toxic substance data storage part The management code indicating the existing chemical substance is collected and stored, the search target substance is selected from the regulated substance data storage section of the law, etc., and the management code is collected and accumulated. By the process of extracting the code, it is possible to calculate the type and amount of the chemical substance included in the product and which is the target of the search.

By using the calculated chemical substance type and amount data, it is possible to display the means for presenting the law or the like regulating the calculated chemical substance and whether it complies with the contents of the standard, or the regulation. Depending on the type of the product and the degree of regulation, the aggregated results are re-edited and displayed for each distinction, or it is included in which parts of the parts data storage unit are limited to specific chemical substances. It is now possible to display only the parts that are in use, or to search and aggregate by focusing on the substances that cause harmful substances when incinerating and cause water pollution, which is a problem when discarding.

As a result, when designing a product, it becomes possible to select components so as to comply with laws and safety standards.
Also, it becomes possible to select a safe disposal method at the time of disposal.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described. FIG. 1 is a block diagram showing the configuration of an embodiment of a product-containing chemical substance management system of the present invention. Parts data storage unit 1 that stores all the contents of the parts used in the product, parts supplier that stores the parts supplier stored in the parts data storage unit, and management number that can uniquely identify which product of the supplier Supplier data storage unit 2 and parts harmful substance data storage unit 3 that stores the contents of chemical substances contained in parts and laws that store chemical substances to be searched specified in laws and regulations or safety standards specified by customers It has four data storage units, such as the regulated substance data storage unit 4. The structure of this storage unit will be described. In the description of this embodiment, a database schema will be described. Of course, in practice, the same applies to file format data rather than a database.

In the parts data storage unit 1, all handled parts to which the design and the present invention are applied are the item master 21 and the parts table 24.
Accumulated in. Item code 22 in item master 21
A management code in which each part is uniquely determined and a name of the part is stored in the item name 23 field. In the parts table 24, the relationships among the parts constituting the product to be searched are described as parent-child relationships. The parent item code 25 is a higher-order assembly part than the part of the child item code 26. The number of members 27 is a number indicating how many parts of the child item code 26 are used. The item code of the item master 21 and the item code of the parts table 24 are commonly used with the same management code managed according to the same rule. All the parts used for one product can be grasped by grasping the relationship between a plurality of records. That is, the component data storage unit 1 has information on components that make up a certain product. In the BOM, it is a general method to have a component structure in a tree structure having a parent-child relationship, but a simple list without a tree structure may be used.

The parts delivery maker data storage unit 2 is the manufacturer of the manufacturer who is the supply source of a certain specific part written with the management code in the item code 22 column of the item master 21 of the parts data storage unit 1. Data related to what kind of product is accumulated. This data is used when purchasing parts. Therefore, the item code 31 of the parts delivery maker data 30 of the parts delivery maker data storage unit 2 is commonly used with the same management code as the item code 22 column of the item master 21 of the parts data storage unit 1. Therefore, the data of the parts delivery manufacturer data storage unit 2 is associated with the data of the parts data storage unit 1. However, if the same management code as the item code 31 of the parts delivery maker data 30 and the item code 22 column of the item master 21 of the parts data storage unit 1 is not commonly used, data of some other association will be provided separately. Alternatively, a method of associating may be used. The supplier company code 32 contains a company code, which is a management code that can uniquely determine the supplier of the supplier of the parts. The company code indicates here the product number 34 that can uniquely identify the part that is the product of the part manufacturer that is the supplier of the part, the product name 33, the product mass 35 attached to it, and the mass that defines the physical unit of mass. Unit code 3
6. There is a data column of the product explanation document 37 for making it easy for the user to understand the contents. In the case of self-production, the management code indicating the company may be entered in the supplier company code 32. The product content explanation document 37 describes an outline of the product. By referring to this, the user can easily understand the content of the product.

Further, the item code 2 of the parts data storage unit 1
The item code 31 of the parts delivery maker data 30 of the parts delivery maker data storage unit 2 for one management number 2
And supplier company code 32, product number 34, product name 33,
That is, there may be a plurality of purchased parts. If there are multiple suppliers, it indicates that there are multiple suppliers of the part. This means that the user can select a part that suits the purpose more from the plurality of parts regarding the contained substance.

The component harmful substance data storage unit 3 stores the contents of chemical substances contained in the components in the component delivery manufacturer data storage unit 2. Therefore, the supplier company code 32, product number 34, and product name 33 of the parts supplier data storage unit 2 and the supplier company code 41, product number 42, and product name 43 of the component harmful substance data storage unit 3 should be the same. Be seen. As the chemical substance management code 44, an individual code that can uniquely identify the substance is entered. Here, it is assumed that a globally common CAS number is used. Substance name 45 is CA
Enter the substance name specified by the S number. Content / rate 46
Enter the value such as how much mass is contained in the part, or what percentage of the mass is the mass. The unit code 47 contains a code that defines in what physical unit the numerical value of the content / rate 46 is written. If there are multiple substances contained in the parts, the supplier company code 41, product number 42, and product name 43 are the same data, and the chemical substance management code 44, substance name 45, content / rate 4
6. A plurality of records having different unit code 47 contents are described. When there are multiple data, it means that the parts contain multiple substances. With a combination of a specific company code and product number,
If the data in the component harmful substance data storage unit 3 cannot be searched by searching, the “contained chemical substances” to be managed are not included. If the "contained chemical substance" to be managed is unknown, the data of the chemical substance management code 44 is nu.
ll. This distinguishes the "not" and "unknown" states.

The regulated substance data storage unit 4 stores the chemical substances to be searched, which are designated according to the regulation by the law or the safety standard designated by the customer according to the law and the safety standard. The structure of the legally regulated substance data 50, which is the content of the legally regulated substance data storage unit 4, will be described with reference to FIG. Regulations worldwide country code 51 that indicates whether the of anywhere in the nation to be done, describing the company / law distinction between the distinction of whether the legal regulations in is whether a particular company, the safety standards of the organization 52 Enter the name of the company / law 53 that describes the name of the law or safety standard, for example, “Dioxin Special Measures Law” or the like. An explanation document 54, in which a document explaining the contents in an easy-to-understand manner is entered, which is the text of the law applied as an example, “(Method of calculating the discharge amount of Class I Designated Chemical Substances) Article 2 The method for calculating the emission of Class I Designated Chemical Substances in Paragraph 1 of Article 5 shall be as follows: In this case, the amount of Class I Designated Chemical Substances released shall be the specified Class I Designated Chemical Substances. (Excluding dioxins) In the case of specified Class I designated chemical substances, in the case of dioxins, the Enforcement Regulations of the Act on Special Measures Against Dioxins (1999 Prime Minister's Ordinance No. 67) Article 3 The amount converted by the method stipulated in 1. shall be calculated based on the amount of Class I designated chemical substances for Class I designated chemical substances other than the designated Class I designated chemical substances. " This description means that the user can understand the purpose of the regulation and the contents of the regulation. If a special calculation or evaluation method is specified, the calculation processing method 56 that describes the method, the management level of chemical substances, that is, whether inclusion is prohibited, whether the amount is regulated, or whether it is used is understood. A company / legal management level 57 that describes the management level such as whether it is a chemical substance group that collects classifications or specific homogeneity properties for management such as regulation by certain laws for convenience and safety standards specified by customers. The company / law management code 58 for managing as a group by the company, the name of the company / law management code 58 uniquely defined by the company / law, and commonly used aliases for easy understanding. Company to enter name / Name of legally controlled chemical substance 5
9. Chemical substance management code 60, chemical substance management code that specifies the chemical substance management code defined by the CAS number, etc. or the chemical substance management code uniquely defined by the company / law or the CAS number, etc. When the management code written in the management code 60 is a specific chemical substance defined by a CAS number or the like, the official name 61 of the chemical substance is entered to enter the formal name of the chemical substance.
If the laws and regulations or the safety standards specified by the customer refer to or comply with the regulations by other laws or the safety standards specified by the customer, the regulations by the applicable laws or the safety standards specified by the customer In order to be able to refer to each other recursively, it is constituted by nest data 62 indicating a place to be referred to such as a legal regulation or a safety standard designated by a customer.
Company / Law management code 58 Company / Law management code 58 to manage collectively as a group of chemical substances, etc. that have classifications for management of laws and regulations, safety standards specified by customers, etc. Is described as a classification for management or a chemical substance group that collects specific homogeneous properties, country code 51, company / law distinction 52, company / law name 5
3. There are a plurality of records having the same company / legal management code 58, company / legal management chemical substance name 59 but different chemical substance management code 60 and chemical substance name 61, and all the chemical substances of the plurality of records are the above. It indicates the contents of the classification for management and the chemical substance group that collects specific homogeneous properties. The existence of this company / legal management code 58 can define the classification of substances, can treat substances as a set according to their characteristics, and can grasp the presence or absence and the amount of substances having specific similar properties for a certain purpose according to the definition. means. Further, the company / legal management level 57 can define the management level of how to manage the substance for each customer company. That is, it is possible to describe the management level such as whether to prohibit inclusion, to regulate the amount, or to grasp that it is being used. Company / Law management code 5
8 indicates a group of substances, whereas company / legal management level 5
7 is the difference in how to handle the substance. A specific example will be described with reference to FIGS. 9 and 10. Details of FIGS. 9 and 10 will be described later. The company / legal management level 57 is a level that should not be used, "prohibition", "reduction" that should not be used, and there is no restriction but "usage" should be understood. Each level is defined. FIG. 9 shows an example of the display of the designation method of the search substance distinguished at the company / legal management level 57. After the search in Figure 10,
The results aggregated by substance group are displayed. The highest level of prohibition is shown in red, the level of reduction is shown in yellow, and the level of management is shown in green to make it easy for users to understand. "Prohibition" and "Reduction" of this company / legal management level 57
The terms and meanings such as “management” may be independently set for each purpose such as regulation by law or safety standard specified by the customer.

The same management code is used for the chemical substance management code 44 of the component harmful substance data storage unit 3 and the chemical substance management code 60 of the legally regulated substance data storage unit 4. If the control code is the same, it means the same substance. If this is different, it may have a conversion method that allows data combination for some comparison and matching.

Conventionally, there is a database etc. that indicates which law a certain chemical substance is involved with, but a mechanism has been created so that data can be processed because it can be referenced and used from other systems. There is a drawback that the delivery regulation condition, which does not exist, or the customer's own voluntary regulation for environmental regulation, is not described in this. In the present invention, the structure of the legally regulated substance data storage unit 4 shown in FIG. 5 makes it possible to combine the laws and regulations and the delivery regulation conditions of the client company into a single data structure to enable search, tabulation and calculation processing. .

For the sake of simplicity, in the present invention, the above-mentioned four data storage units, that is, the component data storage unit 1, the component delivery manufacturer data storage unit 2, the component harmful substance data storage unit 3, and the legally regulated substance data storage unit 4 are used. Although it is explained that it exists in one computer, it may actually exist in the database management system of a specific server,
It may be published on the Internet homepage of the selling company or the homepage of the service company.
If it exists in the database management system of a specific server, if it is published on the Internet by a database inquiry, it is a file in the XML format or a specified record format when requested by the user. Data can be collected at any time in the computer system used by the user in the format shown in FIGS. 2, 3, 4, and 5 by the FTP or other file transfer function.

The contents of the processing function of the processing block 5 of the present invention will be described with reference to FIG.

First, the function of the component structure grasping section 6 will be described. Item master 21 and parts table 2 of parts data storage unit 1
It is assumed that there is a data file according to the schema structure of No. 4. This can be translated into the component configuration tree of FIG. 6 as intermediate data inside the computer. That is, the item code of the first parent item code 25 is registered as the node in FIG. 6, and the item code that corresponds to the child item code 26 is linked to the node. The item of the child item code 26 having this item code as the parent item code 25 is linked to the node of. If this procedure is performed for all the records in the parts table 24, internal data having a tree structure as shown in FIG. 6 defining the relationship of parts of a product can be generated.

Next, the generated tree is sequentially visited from the top to the left, and the items in the parts delivery maker data 30 of the parts delivery maker data storage unit 2 are used with the item code of the item code 22 of each node as a key. A part having the same management number as the code 31 is searched. Supplier company code 32, product number 3 of the parts with the same control number extracted
Using the data of No. 4 as a key, next, management of a plurality of chemical substances with the chemical substance management code 44 having the same management number as the supplier company code 41 and the product number 42 of the component harmful substance data storage unit 3 Extract the code. The extracted chemical substance management code is entered in the contained chemical substance list 65 of the part. If the same supplier company code 41 and product number 42 do not exist, it is interpreted that the content of the chemical substance contained in the part has not been investigated yet and unknown is entered. If the chemical substance management code is null, describe null as the chemical substance of the part does not exist. Then, when the node which does not have the child item code 26 corresponding to the terminal is reached, the contained chemical substance of the part of the node is investigated, and the above operation is performed on the contained chemical substance list 65 for the node at that node to perform the contained chemical substance. Create a substance list. Next, since that node is a terminal, there are no subordinate nodes, so go back to the item code of the parent item code 25 and add all the contained chemical substance lists of the subordinate nodes to the contained chemical substance list in the tree below for that part. create. That is, if this procedure is exhausted, the contained chemical substance list 64 of the component 1 is created.

At the time of the above operation, in the contained chemical substance list, the accurate mass of the component is calculated from the physical unit of the mass unit code 36 which defines the numerical value of the product mass 35 of the component delivery manufacturer data storage unit 2 and the physical unit of the mass. Then, the amount of the relevant chemical substance contained in the mass is calculated from the numerical value of the content / rate 46 of the component harmful substance data storage unit 3 and the content of the unit code 47, and is entered in the contained chemical substance lists 64 and 65.

As a result, a list in which the contained chemical substance list and the amount thereof are entered is generated in the contained chemical substance lists of all the nodes and parts of the component structure tree 63. This is the contained chemical substance calculation list 7 in FIG. The above processing procedure is an explanation of the method to search for all contained chemical substances of all parts, and as an application of this, it can be calculated from the middle of the parts composition tree, or only specific substances can be calculated, The range of can be limited. Further, FIG. 14 shows an example of the contained chemical substance list 7. The contained chemical substance list in FIG. 14 is made up of a chemical substance management code, the amount of the corresponding chemical substance, and data indicating a pointer to the parts configuration tree 60 for convenience.

Next, the processing function of the retrieval target substance extraction unit 10 will be described. The search target substance extraction unit 10 creates a search target chemical substance list 71 based on the contents of the legally regulated substance data storage unit 4 from the contents of which the user specifies the search conditions on the search condition setting screen shown in FIG. To do. The search condition setting screen shown in FIG. 9 is the country code 51 of the regulated substance data 50 of the law regulated substance data storage unit 4, the company / law distinction 52, the company / law code 53 and the company / law management level 5.
It is organized and displayed in a tree shape using the data entered in 7. The prohibition, reduction, and management of customer-specific conditions in FIG. 9 are displayed in an easy-to-understand manner by the user by using the contents of the company / law management level 57 of the regulated substance data storage unit 4 of laws and the like. This allows the user to specify the search substance in a form according to the definition of the company / legal management level 57. Those with a check mark in a square represent that the user has selected this time as a control target that serves as a search criterion. In this screen, a square separated by + -indicates that + is a plurality of contents that can be divided and displayed, and a square-indicates that it is in a state of being expanded and displayed.
By thus expanding and batching the search conditions, it is possible to specify the search conditions collectively or finely.

The search target substance extraction unit 10 meets the designated condition of the regulated substance data storage unit 4 according to the designation of the search condition setting screen of FIG. 9, that is, the country code 5
1. All the chemical substance management codes that match the data of 1, company / law distinction 52, company / law code 53 and company / law management level 57 are extracted. The extracted chemical substance management code is entered in the search target chemical substance list 71 of FIG. The search target chemical substance list 71 of FIG. 7 is the search target chemical substance list 9 of FIG.

5 Country code 51, company / legal distinction 5
2. Company / law code 53 and company / law management level 57
In addition, the company / law management code 58 in the regulated substance data 50 such as laws is set to handle substances having certain special properties and similar characteristics as one set. If the same control symbol is entered here, it can be treated as a group or a set of one control unit. That is, the country code 51, the company / law distinction 52, and the company / law code 53 and the company / law management code 58 that match each other are configured to be regarded as one group or set. On the contrary, all the chemical substance control codes of the matched records may have the company / law control chemical substance name 54 added to the group indicated by the company / law control code 58. For example, the company / law management code 58 is "A
-1 ”, the company / legal control chemical substance name 54 has“ Dioxins ”, and the chemical substance control code is“ 1746-01-
6 ”and the chemical substance name 61 is“ polychlorinated dibenzo-para-dioxin ”. Other "dioxins" include "polychlorinated dibenzofurans" and "coplanar polychlorinated biphenyls", and are collectively referred to as "dioxins" socially. The data structure of the legally regulated substance data 50 in FIG. 5 is configured so that such classification is possible. If the management code of the company / law management code 58 is entered in the chemical substance management code 44 of the parts hazardous material data 30 of FIG. 4 in the parts hazardous material data storage unit 3, it may be treated as the above group or set. It is possible. As described above, it is a condition that the chemical substance management codes of the component harmful substance data 30 and the legally regulated substance data 50 are entered in the same system.

By using the above-mentioned structure of the company / law management code 58, it becomes possible for the user to perform an individual condition-based search. That is, "harmful substances when burned,""harmful substances that dissolve in water,""volatile and harmful substances," etc. are individually classified and the classification code is described in the company / law management code 58, and the substances regulated by law, etc. By setting the number of the substance groups in the chemical substance management code of the data 50, it becomes possible to easily investigate whether or not a dangerous substance of a certain property exists in the parts of the product. The effect of this is when the product is used or discarded, in the environment, for example, when considering such as "is it safe to incinerate when the product is discarded" or when inquiring from consumers. If they match, it is possible to immediately confirm the possibility by creating a group that says "hazardous when burned" and investigating the chemical substances of the product using the present invention.
If the product contains "harmful substances that dissolve in water", it is possible to extract products and parts that may cause water pollution by discarding them as they are at the final landfill site. If some parts are found to be dangerous under a certain condition and only some of them are removed and processed separately, the processing man-hours and costs can be reduced. FIG. 13 shows an example displayed by its nature. The results of totaling chemical substances in products shown in FIG. 13 are shown in FIG. 11 and FIG.
As will be described later with reference to 2, it is displayed together with the display of the counting result.

Nested data 62 is contained in the regulated substance data 50 such as laws shown in FIG. 5 so that one law or safety standard can refer to and comply with another law or safety standard. The nest data 62 can describe contents such as a country code 51, a company / law distinction 52, a company / law code 53, and a company / law management level 57 as necessary. However, depending on the contents, laws and safety standards may recursively conform to each other, and it is necessary to configure the search logic so that records once used, that is, laws and safety standards, are not used twice.

As shown in FIG. 7, the list 9 of chemical substances to be searched is the country code 51 of the regulated substance data 50 of the law, etc., the company / legal distinction 52, the company / The law code 53 and the company / law management level 57 are linked and recorded. Therefore, when the search target chemical substance list 9 is created, it is possible to judge which of the regulated substance data 50 such as laws and safety standards are extracted according to the laws and safety standards of each chemical substance management code listed therein.

Next, the chemical substance matching process 8 of FIG. 1 will be described. In the chemical substance matching process 8, it is assumed that the contained chemical substance calculation list 7 and the search target chemical substance list 9 are completed. When the contained chemical substance calculation list 7 and the search target chemical substance list 9 are matched with each other and the chemical substance management codes are coincident with each other, it is achieved by adding a coincidence mark to the contained chemical substance calculation list 7. This is the search target hit chemical substance list 81 shown in FIG. The contained chemical substance lists 64 and 65 which are the contained chemical substance calculation list 7 are shown in FIG.
The hit target chemical substance list 81 is also present in each node of the component configuration tree 63 of FIG. If necessary, the parts can be created from the middle of the parts configuration tree 63, or can be limited to a specific node, that is, a part.

A method of calculating the search target hit chemical substance amount 82 in FIG. 8 will be described. Chemical substances need to use completely different calculation methods when the environmental assumptions under which the laws and safety standards must be complied with differ. That is, the harmfulness of the substance often differs depending on whether it is an individual, a powder, or a liquid. Therefore, the amount in the contained chemical substance calculation list 7 according to the calculation method 56 of the legally regulated substance data 50, which is the content of the legally regulated substance data storage unit 4, becomes the amount for evaluation according to a certain standard for evaluation. Convert. The calculation processing method 56 is normally null, and
If, no conversion is necessary. In that case, the amount in the contained chemical substance calculation list 7 is directly the search target hit chemical substance amount 82. The amount of hit chemical substance to be searched 82 is the one in which the amount converted into the amount for evaluation is described.

The role of the calculation processing method 56 for the regulated substance data 50 such as laws will be described. For example, "(Emission standard) Article 8 (Omitted in the middle)" of the Act on Special Measures against Dioxins
(I) The amount of dioxins contained in the exhaust gas (The amount of dioxins measured by the method specified by the Ordinance of the Ministry of the Environment is converted to the toxicity of 2,3,7,8,8-tetrachlorodibenzo-para-dioxin in accordance with the Ordinance of the Ministry of the Environment. "The allowable limit (hereinafter omitted)" specified in the "Ministry of the Environment Ordinance""Appendix 3
There is a conversion table for the toxicity of 2,3,7,8-dibenzo-para-dioxin tetrachloride (Article 3 relations). For example, "2,3,3,7,8-8-dibenzofuran dibenzofuran" is described as "0.5". In other words, the conversion factor is specified and each substance is converted into the toxicity of polychlorinated dibenzofuran. Therefore, for example, “* 0.5” representing the multiplication of the coefficient of the calculation processing method 56 is described, and the multiplication is performed if the coefficient is multiplied. It is used to replace the toxicity of a chemical substance similar to the standard toxicity in this way.

A display example of search results by the display / operation screen 11 of FIG. 1 will be described. The result of totaling chemical substances contained in FIG. 10 conforms to the structure of the legally regulated substance data 50, which is the content of the legally regulated substance data storage unit 4, and after the search, based on the configuration of the search condition, the company / legal management level It is a screen displaying search results in a tree shape for each level. In FIG. 10, “prohibition”, which is a level that should not be used for the company / legal management level 57, “reduction” that should not be used, and there is no restriction, but it is necessary to grasp the usage amount. For each level of "management", the result of totaling the substance groups defined by the company / company / law management code 58 independently defined by the company / law is displayed. The highest level of ban is red, the level of reduction is yellow, the level of management is green,
It is displayed so that the user can easily understand it. In this way, it has a function of highlighting and displaying parts that have violated or are likely to violate the specific laws and the delivery regulation conditions of the client company. Further, when the displayed substance group is clicked, the search target chemical substance list 9 is, as shown in FIG. 7, the country code 51 of the legal regulated substance data 50 and the company applied during the process of creating the search target chemical substance list 9 described above. / Law distinction 52,
