突发事件情景下串联式需求系统应急物资协同调度研究

针对突发事件情景下串联式需求系统遭受破坏问题,分析了突发事件情景下串联式需求系统应急物资协同调度的特征。在对系统提供应急物资进行修复的基础上,以串联式需求系统修复的时间最短及成本最小为目标,分别构建了纵向配送的应急物资调度模型和纵向配送与横向转运相结合的应急物资协同调度模型,并设计一种遗传算法对两种模型进行求解。最后通过算例分析,求解得到两种模式下串联式需求系统应急物资调度的最优配送方案,比较解的结果,得出纵向配送与横向转运相结合的应急物资协同调度模式优于一般的应急物资纵向配送模式的结论,验证了该应急物资协同调度模式的有效性和可行性。

Research on the Cooperative Scheduling of Emergency Material in Series Demand System Under the Situation of Emergency

In view of the serial demand system under the situation of emergency, this paper analyzed the characteristics of the collaborative scheduling of the emergency material in the series demand system under the situation of the emergency. To repair the serial demand system we need to provide emergency material, with the target of the shortest time and the minimum cost of repairing the series demand system, the emergency material vertical dispatch model and the emergency material dispatch model combined with the vertical distribution and horizontal transportation are constructed respectively. A genetic algorithm is designed to solve those kinds of models. Finally, through a numerical example, the optimal distribution scheme of emergency material dispatch in series demand system is solved, comparing the results, we get that the combination of vertical distribution and horizontal transportation of emergency supplies cooperative scheduling model is better than the general emergency material vertical dispatch model. Thus, the validity and feasibility of the emergency material cooperative scheduling model are verified.
