多目标的供应链集成优化及数值仿真

MULTI-OBJECTIVE OPTIMIZATION AND SIMULATION OF SUPPLY CHAIN

针对供应链设计中的供应链优化这个关键问题,建立了一个多目标的供应链集成优化模型。该模型将供应链三个层次的优化内容集成在一起进行优化,采用成本、柔性、客户服务水平以及向用户承诺的产品交付时间四个度量指标。针对多目标优化模型,提出了一种改进的多群体遗传算法。最后,利用一个具体实例进行了数值仿真。

The optimization of supply chain is studied. A multi-objective model is constructed, which simultaneously optimizing collaborative enterprises, strategic and operational planning. Moreover, in the model, multi-objective analysis is adopted to allow use of a performance measurement system that includes cost, flexibility, customer service levels and delivery time of products. Furthermore, a improved multi-population pareto genetic algorithm is designed for the model. Finally, the model is illustrated by an example and the simulation result is obtained.
