物流云服务下动态设施选址问题研究

基于云计算的物流云服务平台利用云中的资源,可以实现供应链上资源的优化组合,进而改变了供应链节点间的服务映射关系,真正实现节点间的＂多对多＂映射,从而一定程度上改变动态设施选址的模式。在物流云服务环境下研究动态选址问题,结合云服务环境下＂多对多＂映射关系的特性,以动态P中值选址为例,提出了一种新的基于云服务的动态选址模型,并结合具体算例,运用Cplex求解,证明在物流云服务环境下,可以明显降低选址总成本,同时增加供应链的服务柔性。

Study on dynamic facilities location problems of logistics in cloud services

The cloud computing based logistics cloud services platform can realize optimization of resources in supply chain, thus changing the service mapping relationship between nodes in the supply chain, and realizing the ＂many to many＂ service mapping relationship, which changes the model of dynamic facilities location problem. By giving an example of dynamic P-medi- an problems in logistics cloud services environment where the characteristics of ＂many to many＂ service mapping relationship is combined, this paper proposes a new dynamic facilities location model based on cloud services. By combining with an instance and by use of Cplex to solve problems, the model can significantly reduce the total location cost while increasing flexible service in supply chain.
