砂型铸造企业熔炼批量计划与调度模型及求解方法
Lot Sizing and Scheduling Model and Solution Method for Melting in Sand Casting Enterprise
摘要
Abstract
To solve the problem of inefficiency, difficult allocation of resources, and low utilization of production capacity caused by the artificial lot sizing and scheduling for melting in foundries, an integer programming model was constructed by taking casting delivery date, utilization rate of smelting furnace and conversion of furnace alloys into consideration. According to the characteristics of the model, a heuristic strategy was proposed to decompose the problem into two related sub-problems: (1) lot sizing division of castings pouring with molten metal in the same furnace; (2) the furnace scheduling of melting alloys, which are carried out by dynamic programming and genetic algorithm, respectively. Finally, the effectiveness and superiority of the model and solution method were verified based on the simulation data and real data of a sand casting enterprise, respectively.关键词
