物流配送中心多目标优化选址的仿真设计

Simulation Design of Logistics Distribution Center Multi-Objective Optimization Location

物流配送中心的选址对物流服务能力具有决定性影响,在进行物流配送中心选址时必须综合考虑物流成本和物流服务能力,并以物流成本最小化和物流服务能力最大化为目标,构建了一个多目标优化选址模型。根据模型特点,采用博弈理论的纳什均衡博弈方法对模型进行求解,将模型中的两个目标函数看成博弈方,所有可行的选址方案作为博弈策略集,建立博弈分析的技术路线和计算步骤。最后通过实例仿真,得到满意的设施选址方案。结果证明,选址模型的正确性和有效性,同时表明纳什均衡博弈方法有效地解决选址的多目标优化问题,具有一定的应用前景。

The location of logistics distribution center has great influence on logistics service ability, therefore, the logistics cost and logistics service ability must be considered when the logistics distribution center located. So, a multi-objective optimization location model was established taking into account the logistics cost minimization and lo- gistics service ability maximization. According to the characteristics of the model, the Nash equilibrium game theory was used to solve the mode. With each objective function as game party, all feasible solution as game strategy set, the game analysis technical route and calculation steps were built. Through the simulation of example, the satisfactory facility location scheme was acquired. The result shows that the model is correct and effective, and Nash equilibrium game theory can effectively solve the multi-objective location problem, and will have a preferable application future.
