基于Multi-Agent的应急物资储存点布局优化研究

Research on the Optimal Layout of Emergency Material Storages based on Multi-Agent System

针对应急物资储存点布局优化问题,综合考虑到应急物资保障Agent和应急物资需求Agent的独立性以及指挥Agent的协同作用,基于Multi-Agent方法建立考虑多种因素共同影响的应急物资储存点布局优化模型,并结合优序数法和改进的遗传算法对不同量纲的多目标优化问题进行求解,从而确定应急物资储存点布局最优组合以及每个储存点的物资储备量。仿真结果表明,基于Multi-Agent的应急物资储存点布局优化模型可以协同各部门的意见,从成本、安全和时间多个角度为应急物资保障提供更加合理的布局决策。

Considering the independence of emergency material Supply Agent and Demand Agent and the synergistic action of Command Agent,the optimal layout model of emergency material storages was built based on the perspective of Multi-Agent system in the case of multiple influence factors.The genetic algorithm was improved by the optimal ordinal number method to solve the multi-objective optimization problem.Then the optimal layout of emergency material supply storages and the emergency material reserves were determined.Simulation results show that the model proposed based on Multi-Agent system can coordinate opinions coming from different departments,and provide more reasonable decisions for the guarantee of emergency material in terms of cost,safety and time.
