重大突发事件应急设施多重覆盖选址模型及算法
A Multi-Covering Model and Its Algorithm for Facility Location Response for Large-Scale Emergencies
摘要
Abstract
In order to satisfy the multi-requirements for emergency facilities in response for large-scale emergencies, this paper mainly focuses on the covering location problem. Considering the special characteristics of large-scale emergency response, two concepts are introduced in this paper, that is, the minimum critical covering distance and the maximum critical covering distance for demand point. A multi-covering location model for facility response for large-scale emergencies is proposed based on the multi-quantity and quality service for demand. The objective of this model is to maximize the population covered by facilities as much as possible, addressing the demand uncertainty and multi-time coverage at the same time. The improved genetic algorithm is designed for solving the problem and a computational experiment illustrates how the proposed model works1 on this problem, the results show the effects of the proposed model and the algorithm. So, this proposed model can give some advise for the facility location decision response for large-scale emergencies.关键词
