ALLOCATION OF CHINESE NATIONAL EMERGENCY MATERIAL DEPOSITORY BASED ON FACILITY LOCATION THEORY
针对传统设施选址忽视需求点满意度差异的问题，构建了以总满意度最大化为目标的整数规划模型，并用蚁群算法求解中国国家应急物资储备库的分配方案。
The traditional facility location problems think little of the satisfaction difference between demand sites in the covering radius of facility.Also,there are few documents analyzing the allocation of national emergency material depository of China with quantitative methods.In the light of this situation,we present a maximal covering location problem considering the demand satisfaction difference between demand sites in the domain of facility covering radius and formulate a maximal covering model as an integer programming under the goal of maximizing the total satisfaction of demand sites.After investigating the characteristics of the model formulated,we introduce ant colony optimization(ACO) algorithm to solve the considered problems.Then,we get the allocation result of national emergency material depository of China.The computational result have shown that the model we proposed generate facility location solutions in a more effective manner.Finally,we also propose extensions to our research.
