Patent ID: 7003437

Claim:
A system which evaluates an environmental load of a product, comprising: 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; an evaluation rule storage unit which stores an evaluation rule of an environmental load; an evaluation processing unit which extracts 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; a parts totalization processing unit which extracts 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 generates total information of the environmental load information; and an output processing unit which outputs the total information of said environmental load information to an output interface.
