突发事件应急设施选址问题的模型及优化算法

A Model of Emergency Rescue Facility Location Problem for Emergency Incidents and Its Optimal Solution Algorithm

综合考虑应急设施选址的公平性、效率性、设立成本等多方面的因素,建立了一个可适应重大突发事件救援设施不同部署策略的多目标规划决策模型.利用模拟植物生长算法的通用模型,提出了基于模拟植物生长思路的目标问题求解方法.通过对实例的计算,结果验证了多目标决策模型的可行性与合理性,模型的求解算法可获得最优解,具有良好的性能.

Considering the fairness, efficiency, constructing cost and some other factors of emergency rescue facility location, a multi-objective decision model which can apply to different deployment decisions for large-scale emergency incident facility locations. According to the general model of plant growth simulation algorithm, a solution method of target function based on plant growth simulation is proposed. By calculating on the real instances, the result shows the feasibility and rationality of multi-objective decision model, the model is optimized with the proposed solution algorithm, the proposed method has a better performance.
