Configuration Model for Post-disaster Emergency Medical Service Stations Considering Deprivation Cost
摘要
Abstract
China has a vast territory with a wide variety of natural disasters,and is one of the countries in the world that often suffer from natural disasters.The huge impact range of large-scale disasters,the adverse impact on the affected population,and the low probability of disaster occurrence pose new challenges for decision-makers on how to reasonably allocate emergency facilities and effectively allocate emergency rescue materials to ensure people’s lives and protect their safety.The medical rescue for disasters in China mainly adopts the"on-site treatment"mode,and the location and material allocation of emergency medical mobile hospitals directly affect the rescue efficiency.Protecting the life safety and physical health of the affected population,and maintaining social stability are the starting point and foothold of emergency rescue.Therefore,the psychological pain caused by the lack of rescue materials among the affected population during the post disaster emergency rescue process cannot be ignored.This article uses the cost of deprivation to measure the psychological feelings of the people in disaster areas,considering economic costs and deprivation costs as the decision-making objectives of the medical service station configuration model,medical service station configuration,and material allocation model.It models emergency rescue operations after disasters,providing a reference basis for decision-makers in emergency medical service station configuration and material allocation. In the"on-site treatment"mode in disaster medical rescue,the location of an emergency medical mobile hospital directly affects rescue efficiency.Based on the deprivation cost,a multi-objective two-level medical service station configuration model is constructed to optimize rescue efficiency and psychological trauma equity of the affected people.Relative deprivation cost is used to describe the fairness of relief and absolute deprivation cost is used to describe the pertinence of relief.Taking the Lushan earthquake emergency rescue in Sichuan province as an example,the feasibility of the model and solution method is verified.The experimental results show that a slight increase in an economic cost can alleviate people’s panic caused by the shortage of medical supplies,reduce the difference in psychological trauma of the affected people,and improve the response speed of emergency rescue. The research results of this article enrich the site selection decision-making problem of emergency medical service stations and provide new decision-making methods for the development of emergency disaster relief work.This article does not consider the issue of horizontal transportation of emergency supplies at the same level of medical service stations.Therefore,the horizontal transportation of supplies at the same level of site selection points is the next research focus of the author.关键词
