基于时间可靠性分析的农产品轴辐式物流网络节点选址

Nodes location of the shaft radial logistics network of agricultural products based on the analysis of time reliability

针对农产品轴辐式物流网络的特点及农产品物流时效性要求,将系统可靠性应用于农产品物流网络节点选址研究中。在满足用户规定的时间可靠度要求的前提下,建立了以运输总成本最小为目标的农产品物流网络节点选址模型,并设计基于全局协同搜索的混合蛙跳算法(SFLA)对模型进行求解。最后通过算例分析,验证了模型的合理性和有效性。研究结果表明,将时间可靠性分析应用于农产品物流网络节点选址研究,能够满足用户对运输时效性的要求,降低了物流运输成本,提高了农产品物流的时间可靠度。

According to the characteristics of the agricultural products shaft radial distribu- tion network and timeliness requirements, this paper has researched the location of agricul- tural products logistics network nodes,under the premise of combining system reliability a- nalysis. To satisfy the requirement of the reliability specified, this paper has established the minimum transportation cost as the total target of agricultural products logistics network nodes location model, and has solved it with shuffled frog leaping algorithm（SFLA） based on global search, to verify the validity and rationality of the model through the case analy- sis. The results show that the time reliability analysis for agricultural products logistics network nodes location analysis can satisfy the requirements of the users of transportation timeliness, im- prove the time reliability of the agricultural products logistics and reduce logistics cost.
