基于遗传算法的多军事物流配送中心选址决策

Study on Decision-making Concerning Location Allocation of Multiple Military Logistics Distribution Centers Based on Genetic Algorithm

军事物流配送中心是军队物资保障的核心元素,而选址作为军事物流配送中心建设的一项重要工作,对后勤保障效率的提高具有重要意义。结合军事物流配送中心的配送流程,以满足部队物资需求量为基本约束条件,以配送中心建设的固定费用与配送成本之和为目标函数,建立了多军事物流配送中心选址决策模型。采用遗传算法对全局变量进行系统搜索比较,得到模型的最优解,解决了多军事物流配送中心的选址和服务需求分配问题。以军队某片区物流配送中心的选址为例,建立多军事物流配送中心选址决策模型。算例结果表明,该模型可为下一步军事物流配送中心建设选址提供参考。

In this paper, in connection with the operation process of the military logistics distribution centers and with the satisfaction of the material demand of the army as the basic constraining condition, we established the multiple military logistics distribution center location decision-making model which aimed at minimizing the sum of the fixed construction cost and the operation cost of the logistics distribution centers, then used the genetic algorithm to obtain the optimal solution of the model to solve the problems in the location allocation and service demand allotment of the distribution centers, and at the end, applied the model to an empirical case.
