An Approach Based on Coloured Petri Net and NSGA-II to Improve the Emergency Department

Abstract

Health care sector faces major challenges in light of the emergence of new diseases. The emergency department (ED) is an important area in the hospital, where it plays a major role in the presence of these challenges. The ‘ED’ is a complex system due to the random flow of patients and the complex nature of its resources. In this paper, the authors model and simulate the ‘ED’ by means of coloured Petri nets, and to determine the appropriate amount of resources, the NSGA-II algorithm is developed. After determining the appropriate amount of resources through the NSGA-II algorithm, the simulation model of the current system is modified with the amount of new resources obtained through the NSGA-II algorithm. The results are compared between the current system and the obtained system. This study was conducted in Hassani Abdelkader Hospital, located in the city of Sidi Bel Abbes, in western Algeria.
