摘要
通过顾客服务需求效用期望的函数描述,分析了顾客流量分配规律随机性特征,界定了服务节点设施期望截获的顾客流量分布;考虑节点设施的生存约束条件,构建了具有流量需求下限约束的服务设施截流选址模型。实证研究表明,通过估计和优化一定节点服务设施的顾客流量下限约束及其满足概率,服务节点截流选址模型可有效地帮助投资主体寻求回报率最大的服务节点组合,并对新建服务节点决策提供数据支持。
Often it requires a lower demand bound to build a service node. Based on this requirement, this paper discusses the interception flow location problem with lower demand bound constraint considered. By presenting a utility function of customer demands, the stochastic distribution characteristics of customer flows is analyzed and the intercepted distribution of the customers of each service node is given. Then, a flow interception location model with lower demand bound constraint is presented by analyzing the operation constraints of the node facility. A case study is given to verify the application of the proposed model. Re- sult shows that, by the estimation and optimization of the lower demand bound and its satisfied probability for each service node, the proposed model can help the stakeholders to solve the location problem and obtain the largest return.
