电子物流系统采购策略中的QoS模型研究

Research of Purchasing Decisions QoS Model Based on E-logistics System

电子商务是互联网快速发展的产物,电子物流系统是其中一个重要环节和研究热点.本文主要通过分析物流系统中的采购决策问题,对于采购决策中存在的供应商选择和订单选择问题分别提出了相应的调度算法和选择策略.然后,以电子商务系统中的物流系统为例,在随机Petri网模型建模的基础上,对物流系统采购决策中的订单处理流程进行了QoS模型建模,并且在此模型基础上应用本文提出的选择策略及调度算法,给出模型相对应QoS性能结果分析.

E-commerce is a product of the rapid development of Internet,and e-logistics system is an important part and hot research of E-commerce.In this paper,through the analysis of the logistics system′s procurement decision-making problem,in order to solve the problems of the supplier selection and order selection of purchasing decisions,corresponding scheduling algorithm and selection strategy are proposed.Then,taking the logistics system of e-commerce systems as an example,on the base of Stochastic Petri Net modeling,the paper models the QoS model of the order process of the logistics system′s procurement decision-making,and with the application of the scheduling algorithm and selection strategy proposed in this paper,gives the QoS performance evaluation and analysis.
