A public emergency evacuation route optimization method under nuclear accident

Abstract

The invention relates to information processing technology and provides a method for optimizing public emergency evacuation routes under nuclear accidents. The method includes: determining the scope of the emergency planning area, gridding the emergency planning area, determining the environmental release source item of the nuclear accident, and obtaining the wind field data in the emergency planning area; The activity concentration of each radionuclide in the grid is used to evaluate the radiation dose rate in the emergency planning area; the road nodes of the public emergency evacuation path are determined according to the road network of the emergency planning area, and the connection relationship and attribute information between the nodes are determined to form an evacuation plan. Network; according to the grid of the starting point and end point of the evacuation path, based on the improved chaotic ant colony algorithm, the set of all evacuation paths with a relatively low radiation dose rate to the public is obtained; according to the evacuation time and radiation of each path in the set of all evacuation paths The multi-objective decision-making optimization is carried out to determine the optimal path. The invention provides important basis for formulating nuclear emergency plan.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method for optimizing public emergency evacuation route information under nuclear accidents by using a computer. Background technique [0002] The urgency of energy transformation is increasing day by day, and nuclear energy is a safe, economical, efficient and clean energy, and an important energy choice for addressing climate change. In the process of developing nuclear power, due to the influence of human, equipment, production management or environmental factors, uncontrolled release of radionuclides occurs from time to time, which brings huge losses to people. The positioning statement in nuclear power-related planning is "safely and securely advancing nuclear power construction", so emergency planning procedures are critical to protecting the population and the environment, and mass evacuation or shelter-in-place has been used as a means to protect people f...

Problems solved by technology

[0004] In order to overcome the defects in the current public emergency evacuation route planning process under nuclear accidents, the present invention uses computer information processing technology to provide an optimization method for public emergency evacuation routes under nuclear accidents. Based on the ant colony algorithm, the traditional evacuation To solve the problem that the path planning method is too conservative, a new evacuation path planning method is proposed, which can quickly reflect the path with less radiation and improve the search efficiency of the algorithm
