In the emergency management relevant to chemical contingency spills, efficiency emergency rescue can be deeply influenced by a reasonable assignment of the available emergency materials to the related risk sources. In this study, an emergency material scheduling model (EMSM) with time-effective and cost-effective objectives is developed to coordinate both allocation and scheduling of the emergency materials. Meanwhile, an improved genetic algorithm (IGA) which includes a revision operation for EMSM is proposed to identify the emergency material scheduling schemes. Then, scenario analysis is used to evaluate optimal emergency rescue scheme under different emergency pollution conditions associated with different threat degrees based on analytic hierarchy process (AHP) method. The whole framework is then applied to a computational experiment based on south-to-north water transfer project in China. The results demonstrate that the developed method not only could guarantee the implementation of the emergency rescue to satisfy the requirements of chemical contingency spills but also help decision makers identify appropriate emergency material scheduling schemes in a balance between time-effective and cost-effective objectives.
在与化学突发事件溢出相关的应急管理中,合理地将可用应急物资分配给相关风险源,可以深刻影响到高效的应急救援。在本研究中,开发了一个具有时效性和经济性目标的应急物资调度模型(EMSM),以协调应急物资的分配和调度。同时,提出了一种改进的遗传算法(IGA),其中包括对 EMSM 的修订操作,以确定应急物资调度方案。然后,基于层次分析法(AHP)方法,通过情景分析评估在不同威胁程度下不同应急污染条件下的最优应急救援方案。最后,将整个框架应用于中国南水北调工程的计算实验。结果表明,所开发的方法不仅可以保证应急救援的实施,以满足化学突发事件溢出的要求,还可以帮助决策者在时效性和经济性目标之间找到平衡,确定合适的应急物资调度方案。
