为了解决多受灾点应急资源配置过程中出现的分配不均和资源竞争问题,本文建立一种以双层决策方法为基础的多受灾点应急资源配置模型,使应急资源配置过程兼顾及时性与公平性,从而确保各受灾点均能尽早开展应急工作。但采用遍历搜索策略对双层规划模型求解存在时间复杂度高的问题,本文依据应急出救的就近原则,提出一种多受灾点一多出救点应急资源配置动态优选策略,能够快速求取双层应急资源配置模型的全局最优解。最后,通过详细的算例分析证实算法的有效性。
In order to solve the unfairness and competition problem of emergency resources distribution among multiple disaster places, an emergency resource allocation model based on bi-level decision method is established. It can make rescue activities timely and fair, and ensure rescue starting time in each disaster place as early as possible. But obtaining the optimal solution of bi-level programming model with simple enumeration strategy needs too much time to satisfy the time requirement of emergency. To overcome this difficulty, a dynamic optimizing strategy is proposed in terms of the near supplier first rescue principle, which could obtain the global optimal solution of bi-level emergency resource allocation model fast. Finally, a case study is made to verify the algorithm validity.
