METHOD FOR EVALUATING LIFE CYCLE ENVIRONMENTAL EFFECT AND EVALUATION SYSTEM THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a life cycle environmental effect evaluation (LCA) system for a product comprising a complicated material and/or complicated parts, shortening a calculation processing time without setting part data as a tree structure and reflecting the recycling data of the material of a combination origin to the LCA calculation of the whole of a product even if new part data is formed by a combination of parts and a process, and accurately calculating LCA more actually and faithfully through respective stages of production, recycling and disposal.;SOLUTION: In the life cycle environmental effect evaluation (LCA) system, recycling quantity distribution data wherein the weights of parts are divided proportionally as a material unit and a recycling method unit is included in part data. The recycling quantity distribution data of a plurality of part data are divided proportionally and totalized as the material unit and the recycling method unit to form the new recycling quantity distribution data of the part data.;COPYRIGHT: (C)2003,JPO
