System, method and program for evaluating environmental load

A method of evaluating an environmental load of a product by use of an information processing unit including a parts construction database which stores a parts number determined for specification of each parts constituting said product, type number information determined for each parts constituting said product and information of a master-slave relation between a master parts and slave parts constituting said master parts, in association with one another;

• an environmental load information database which stores environmental load information of said parts constituting said product for each of said type number information;
• and an evaluation rule storage unit which stores an evaluation rule of an environmental load;
• said method comprising the steps of:
• extracting from said environmental load information database environmental load information relating to one or a plurality of type number information associated with one parts number on the basis of association of a parts number and type number information in said parts construction database, applying the environmental load information extracted to the evaluation rule of said evaluation rule storage unit and judging whether or not corresponding type number information can be an evaluation object type number of the environmental load as a representative of the parts number;
• extracting the environmental load information of said evaluation object type number from said environmental load information database, totalizing the environmental load information for each of said evaluation object type numbers for each master parts or for each product on the basis of said parts construction database and generating total information of the environmental load information;
• and
• outputting the total information of said environmental load information to an output interface.

A computer program product, residing on a computer readable medium, which executes the step of evaluating an environmental load of a product by use of an information processing unit including a parts construction database which stores a parts number determined for specification of each parts constituting said product, type number information determined for each parts constituting said product and information of a master-slave relation between a master parts and slave parts constituting said master parts, in association with one another;

• an environmental load information database which stores environmental load information of said parts constituting said product for each of said type number information;
• and an evaluation rule storage portion which stores an evaluation rule of an environmental load;
• said program comprising the steps of:
• extracting from said environmental load information database environmental load information relating to one or a plurality of type number information associated with one parts number on the basis of association of a parts number and type number information in said parts construction database, applying the environmental load information so extracted to the evaluation rule of said evaluation rule storage unit and judging whether or not corresponding type number information can be an evaluation object type number of the environmental load as a representative of the parts number extracting the environmental load information of said evaluation object type number from said environmental load information database, totalizing the environmental load information for each of said evaluation object type numbers for each master parts or for each product on the basis of said parts construction database and generating total information of the environmental load information;
• and outputting the total information of said environmental load information to an output interface.
