METHOD FOR CALCULATING EXCESS AND DEFICIENT AMOUNT OF BASE MATERIAL AND SYSTEM FOR CALCULATING EXCESS AND DEFICIENT AMOUNT OF BASE MATERIAL

摘要

PPROBLEM TO BE SOLVED: To facilitate the totalization of the excess and deficient amount of base materials including the stocks of parts and steel products. PSOLUTION: A method for calculating the excess and deficient amount of the base materials comprises: providing the base materials with base material group numbers classified into classes containing physical specifications and commercial distribution information on the base materials; collecting the stock amount of the parts, that of the steel products, and that of the base materials in a manufacturing system for every base material group number; converting the collected stock amount of the parts into the weight of the first base material by a parts-base material unit conversion table containing the weight obtained when the parts are converted into the base materials; converting the collected stock amount of the steel products into the weight of the second base material by a steel product-base material conversion table containing the weight obtained when the steel products are converted into the base materials; converting the collected stock amount of the base materials into the weight of the base materials; adding the converted weight of the first base material to that of the second base material to totalize the converted total stock amount of the base materials converted into the base materials in the manufacturing system. The excess and deficient amount of the base materials is calculated by comparing the converted total stock amount of the base materials with base material conversion use scheduled amount obtained by converting a parts use scheduled amount for every base material group number of a user by a parts-base material unit conversion table.
