摘要:

突发自然灾害及其次生灾害易导致受灾点信息传递滞后、模糊,进而造成受灾点应急物资供应不足,为解决这一问题,在受灾点间引入横向转运方式进行应急物资协同调度。基于加权秩和比(WRSR)综合评价法,计算物资不足的受灾点物资紧迫程度,作为受灾点物资调度顺序的依据;考虑灾后道路损坏对调度时间和成本的影响,引入随机道路通行率系数,以时间最短和成本最低为目标,构建考虑横向转运的应急物资二次调度模型;采用遗传算法求解模型,并与无横向转运调度结果进行对比。结果表明:引入受灾点间横向转运,能有效减少调度时间,降低调度成本,缩短各受灾点应急物资“空窗期”,提升应急物流效率和应急物资配送网络韧性。

Abstract:

In view of the abruptness of natural disasters and their secondary disasters, which make the information transmission at the disaster-affected points lag and fuzzy, resulting in the shortage of emergency supplies at the disaster-affected points, horizontal transportation had been introduced for coordinated scheduling of emergency materials between disaster sites in this paper. The WRSR comprehensive evaluation method was used to calculate the urgency of material as a basis for material scheduling orders in disaster-affected points that were insufficient. The random road traffic rate coefficient was introduced to address the impact of post-disaster road damage on scheduling time and cost. With the goal of minimizing time and cost, a quadratic scheduling model for emergency materials considering lateral transportation was constructed. The genetic algorithm was used to solve the model, and the results were compared with those of no horizontal transfer scheduling. The results show that the introduction of horizontal transfer between disaster-affected points effectively reduces the scheduling time and cost, shortens the "empty window period" of emergency materials at disaster-affected points, and improves the efficiency of emergency logistics and the resilience of the emergency materials distribution network.
