基于SPN模型的物流采购决策

Logistics Purchasing Decision-making Based on SPN Model

在电子商务物流管理系统(ELMS)中,针对采购决策存在的供应商选择和订单选择问题,根据ELMS采购流程和多属性决策方法得到供应商选择调度算法,利用基于随机Petri网的多服务器多队列模型实现订单选择策略。性能分析结果表明,该方法能有效减少ELMS系统的响应时间,并提高其吞吐率。

Aiming at purchasing decision-making existing problems of supplier and order selection in E-business Logistics Management System（ELMS）, this paper gets supplier selection scheduling algorithm according to ELMS purchase process and multi-attribute decision-making method. It realizes order selection strategy using multiple servers multi-queue model based on Stochastic Petri Net（SPN）. Performance analysis results show that this method can effectively enhance throughput and reduce rate response time of ELMS.
