Passing multiple conveying paths from entrance vessel preparation of plan

摘要

PROBLEM TO BE SOLVED: To optimize an tank filling schedule for a raw material storage tank and raw material physical distribution control in a raw material facility while preventing stock of the raw material storage tank from becoming depleted and enhancing operability of a conveying facility.;SOLUTION: In the tank filling schedule preparation method to the raw material tank, a function S203 for extracting the raw material storage tank in which a replenishment level is cut by the present physical distribution state and information and extracting a conveying route allotting pattern to the raw material storage tank; a function S204 for establishing all allotting pattern from the conveying route; a function S205 for additionally extracting the raw material storage tank capable of performing tank filling by the conveying facility not extracted in every established combination; a function S206 for establishing linear type and integer restriction type mathematical models relative to all conveying route allotting pattern based on the present physical distribution state and restriction of physical distribution respectively; a function S207 for optimizing the respective mathematical models based on the target function; and a function S209 for extracting the combination indicating the best evaluation value in the optimization result to make it as the final result are provided.;COPYRIGHT: (C)2006,JPO&NCIPI
