Volunteer dispatch considering fatigue effect and satisfaction in emergency situation

Abstract Rescue organization scheduling is a hot issue in the field of emergency management, in which the participation of volunteer rescue organizations, a social force, is of great significance to improve the efficiency of emergency rescue. In the case of known rescue services required by the affected place and the information of rescue services provided by volunteer rescue organizations, the goal is to maximize the satisfaction of the victims and minimize the fatigue of the volunteer rescue organizations. The volunteer rescue organization scheduling problem is an NP-hard problem. To solve the studied problem model, two multi-objective optimization algorithms are applied in this article. With the goal of improving the overall rescue efficiency of volunteer rescue organizations implementing rescue at the disaster site during a single emergency, this study analyzes the practical problems related to emergency rescue, taking into account the effects of the time sensitivity of the disaster victims, the preference of the rescue services, the fatigue accumulation rate of the volunteer rescue organizations, and the matching of the rescue skills. Finally, this article distills some scheduling strategies applicable to emergency volunteer rescue organizations, hoping to provide theoretical basis and practical guidance for the Emergency Management Center and related emergency management departments to better configure and optimize emergency human resource scheduling problems.
