动态竞争环境下的物流配送中心双层规划模型

考虑服务水平、产品价格、沟通便利性和距离对客户效用的影响以及服务水平和产品价格之间的关系,建立动态竞争环境下,以企业为领导者、以竞争者为跟随者的物流配送中心双层规划模型,以带精英策略的快速非支配排序等遗传算法设计迭代求解算法并进行仿真分析.仿真结果表明,企业总利润和总销量所占比例分别为49.19%和55.66%,不仅有效平衡了产品价格和服务水平,而且以满意的利润获得了市场份额上更大的优势.

Bi-level programming of logistics distribution center in dynamic competitive environment

A bi-level programming model is established to optimizing the logistics distribution center in the dynamic competitive environment, which considers the influence of service level, price, communicating convenience and distance on customer’s utility, and takes the relationship between service level and price into account as well. In the model, the enterprise acts as the leader, and the competitor acts as the follower. Furthermore, an iterative algorithm is designed based on the elitist and fast non-dominated sorting genetic algorithm, and a simulation example is studied. Analysis results show that the proportions of enterprise’s total profits and total sales are 49.19% and 55.66% respectively. The enterprise not only strikes an effective balance between the price and the service level, but also gains greater advantages on the market share with satisfactory profits.
