Optimization Scheduling Of Emergency Bottle-neck Resource With A Perspective Of Stakeholders

The frequent outbreak of public emergencies presents tremendous threatens to the safety and health of people around the world,which also causes severe damage to the sustainable development of society and economy,the need for effective disaster operations management measures or scheduling schemes to deal with public emergencies is pressing.As the direct stakeholders of disaster operations management,the gains and losses of the victims in public emergencies can reflect the effectiveness of the measures or schemes.Their gains and loss affected by the disasters are influenced by the subject behavior of emergency rescue organizations and the emergency bottleneck resource suppliers,as well as by the system efficiency of emergency bottleneck resources.Therefore,disaster operations management with the consideration of the game behavior regarding tripartite stakeholders and optimal allocation of emergency bottleneck resources based on stakeholders' perspective has high practical value and important theoretical significance for improving its actual benefits.Response phase as the focus of this paper is subdivided into golden rescue,buffer rescue,and emergency recovery stage.The victims are also divided into the seriously injured,the lightly injured and the uninjured stranded.Firstly,psychological risk perception function of different victims in different emergency response stages is constructed based on prospect theory,it also quantifies the loss of psychological risk perception in disaster operations management.Next,based on evolutionary game theory,the gain and loss of emergency rescue organization,the emergency bottleneck resource suppliers and the victims in the disaster operations management are discussed,the stability of the strategy point and the asymptotic stability of the strategy equilibrium point concerning the tripartite game behavior are analyzed.Then,a 0-1 nonlinear multi-objective integer programming model is established to minimize the system efficiency of the emergency bottleneck resources and the loss of the victims' psychological risk perception.And genetic algorithm is designed to solve the problem.Finally,practical case is presented to verify the feasibility and effectiveness of the proposed model,as well as computational results are portrayed by Pareto and sensitivity analysis.Based on the above,a reasonable disaster operation management scheme and an optimal emergency bottleneck resource allocation method are proposed.This paper synthesizes prospect theory and evolutionary game theory to solve the following problems.(1)The loss of psychological risk perception in disaster operations management is quantified based on prospect theory.(2)A tripartite stakeholder game model of emergency rescue organization,the emergency bottleneck resource suppliers and the victims in disaster operations management in response phase is established based on evolutionary game theory.(3)A 0-1 nonlinear multi-objective integer programming model is established to minimize the system efficiency of emergency bottleneck resources and the loss of psychological risk perception.Based on discussion and analysis,the proposal of managerial insights for disaster operations management are presented in three aspects as follows.(1)while the strategy combination of emergency rescue organization,the emergency bottleneck resource suppliers and the victims is {cooperation,charitable donation,positive response},the game strategy of tripartite stakeholders reaches an evolutionary stable state in the emergency response phase.(2)while the needs of victims are satisfied by emergency rescue organizations and emergency bottleneck resource suppliers within 250 to 270 hours before the outbreak of public emergencies,the loss of psychological risk perception concerning victims presents the most obvious decline;(3)While the ratio between the scale of emergency bottleneck resources and that of victims is higher than 3:275,the victims' loss of psychological risk perception is low.When that ratio is less than 3:160,the higher loss of psychological risk perception regarding victims can be avoided,the system efficiency of emergency bottleneck resources is also low.
