Emergency Medical Service Station Robust Location Model and Algorithm Under Demand Uncertainty
摘要
Abstract
After large-scale emergent incidents,it is particularly urgent to start emergency relief network quickly and locate the emergency medical service stations.We incorporate demand uncertainty,introduce three uncertain level parameters,construct four types of demand uncertainty sets,and propose robust EMSS location models respectively.Then,we derive their tractable robust counterparts,and employ branch-cut algorithm to solve the problems..Finally,we present computational results,and perform sensitivity analysis.Numerical results show that,among four robust location models,robust EMSS location model with ellipsoid uncertainty set opens fewer EMSSs,and the total cost is smaller.According to the uncertainty of risk preference,decision-makers usually choose optimal budget uncertainty and demand disturbance proportion,so as to minimize the total cost.关键词
