Modeling and Simulation of Emergency Resource Allocation Process Based on Generalized Stochastic Petri Net

Abstract

The outbreak of emergencies usually triggers the phenomenon of a lack of emergency resources, and the lack of resources may lead to untimely rescue affecting the social life order. How to guarantee a smooth and efficient emergency resource allocation process and improve the efficiency of emergency relief disposal is the key to ensuring the successful completion of disaster relief tasks. To this end, this paper focuses on the emergency resource allocation process and considers the recycling of emergency resources after disaster relief with the background of emergencies. An emergency resource allocation process model is constructed based on the generalized stochastic Petri net, and the activity, reachability, boundedness, and security of the model are analyzed. The homogeneous Markov chain is utilized for simulation, and the performance analysis is carried out by calculating the steady-state probability and transition utilization rate of each state using examples. Simulation results show that the database and the recovery process should be the key steps to optimizing the emergency resource allocation process. Therefore, improving the effectiveness of these critical links' emergency disposal will further improve the effectiveness of emergency resource allocation.
