Abstract
The location and allocation of emergency supplies are an important part of emergency rescue work. The existing emergency location and allocation process is inefficient, costly, and neglects the psychology of victims. To improve the emergency relief work and solve the current problems, this paper introduces the victims’ pain perception cost into the model, takes the lowest cost of the whole emergency rescue system as the goal, constructs a government–enterprise joint emergency material location–allocation model, and uses the simulated annealing algorithm to solve the model. This paper takes the 2008 Wenchuan earthquake in Sichuan Province as the background and verifies the validity and rationality of the model through a comparative analysis of case simulations. The results show that the model and algorithm can effectively solve the emergency supplies location–allocation problem considering the victims’ pain perception, reflecting the idea of human-centered sustainable development and providing support for building a sustainable emergency relief system.
Highlights
The location and allocation of emergency supplies are an important part of emergency rescue work
Factor along with the “material” factor, quantifies the victims’ suffering perception function, considers its impact on the location–allocation process, and uses the suffering perception cost to reflect the delay of supplies, which is more in line with the actual situation
The location–allocation model of emergency supplies built in this paper mainly considers the transportation of various types of supplies between two types of warehouses, and vehicles depart from each warehouse site and transport the supplies to the disaster site according to the demand
Summary
The location and allocation of emergency supplies are an important part of emergency rescue work. To improve the emergency relief work and solve the current problems, this paper introduces the victims’ pain perception cost into the model, takes the lowest cost of the whole emergency rescue system as the goal, constructs a government–enterprise joint emergency material location–allocation model, and uses the simulated annealing algorithm to solve the model. The results show that the model and algorithm can effectively solve the emergency supplies location–allocation problem considering the victims’ pain perception, reflecting the idea of human-centered sustainable development and providing support for building a sustainable emergency relief system. Existing research usually treats the government as the entity responsible for the entire emergency logistics rescue system, which brings a huge financial burden and causes a massive waste of resources [6].
