基于MTO的多目标优化排产模型

A Multi-Objective Optimization Model in MTO Scheduling

针对多订单情况下多产品生产计划安排研究存在不足,提出了一种新的基于订单的计划排期多目标优化模型,目标包括利润最大化与均衡生产,通过各计划期之间产量安排对各资源消耗的偏差最小化来实现均衡生产。模型存在非线性多目标,实现时采用了遗传算法,通过Sheffield GATBX利用MATLAB编程实现。

For multi-order and multi-product manufacturing invimment, a new multi-objective optimization model in MTO scheduling is proposed. The two objectives of profit maximization and production leveling are achieved by minimizing the bias of the resource consumption between two successive schedule periods. The model is solved by a genetic algorithm. It is implemented with MATLAB and Sheffield GATBX.
