Abstract
China is located in the intersection area of two seismic zones. Due to this special geographical location, earthquake disasters occur frequently in China. Earthquake emergency rescue work is one of the key construction works of disaster prevention and mitigation in China. This paper mainly studies the earthquake disaster rescue model based on the complex adaptive system theory and establishes the earthquake disaster rescue model by analyzing the complex adaptive system theory and combining the earthquake rescue process. In this paper, through the task allocation mechanism task, the disaster rescue task is divided into simple task and complex task, and the executive task subject is divided into single task subject and multitask subject. On the basis of considering the shortest emergency rescue time goal and the goal of maximizing the deployment utility of rescue team, the reasonable deployment of a rescue team is realized through a complex adaptive system, that is, the deployment utility of the rescue team is maximized. In this paper, the simulation experiment and comparison of the earthquake disaster rescue model based on the complex adaptive system theory are carried out. The experimental results show that the model used in this paper is better than the other two models in terms of algorithm convergence, rescue number, and overall score; in different scenarios, the relative survival probability of the model in this paper is 58.92%, 67.85%, and 77.46%, and the proportion of the wounded rescued is 66.31%, 76.45%, and 83.06%, which were higher than those of the other two models. The earthquake disaster rescue model based on the complex adaptive system theory proposed in this paper provides an effective theoretical basis and method system for postdisaster emergency rescue decision making and enhances and improves the emergency response ability to deal with large-scale geological disaster events.
Highlights
Large-scale earthquake disaster has become the focus and difficulty of research because of its wide influence range, huge population, serious economic loss, high uncertainty, derivation, and evolution
It can be seen that major geological disasters have a large influence range, a large number of affected population, and serious economic losses, which can have a serious impact on people’s lives and even cause devastating consequences
It is necessary to strengthen the work of emergency rescue and response to major earthquake disasters
Summary
Large-scale earthquake disaster has become the focus and difficulty of research because of its wide influence range, huge population, serious economic loss, high uncertainty, derivation, and evolution. The occurrence of major earthquake disasters is more frequent, resulting in serious losses and difficult rescue, which is the focus and difficulty of emergency management research. In order to better describe the force of individual pedestrian evacuation, the model established three indicators including self-driving force, surrounding pedestrian influence, and surrounding obstacle influence Their conclusion is not supported by specific experimental data [3]. By analyzing the task allocation mechanism and team deployment model, this paper studies the optimization method of emergency deployment decision making of a rescue team, which can effectively save the wounded and minimize the loss caused by the disaster, so as to realize the improvement of the emergency rescue effect in a real sense and provide a reliable basis for disaster relief and disaster reduction work.
