Chemical accident multi-target two-stage emergency rescue material scheduling method

Abstract

The invention provides a chemical accident multi-target two-stage emergency rescue material scheduling method. In the first stage, on the basis of a traditional vehicle path planning method, a rescuevehicle path planning model based on road risks is constructed by fully considering the risk influence of initial accidents and domino effects of a chemical industrial park on the park and surroundingroads, and a relatively safe rescue vehicle driving path is planned. Aiming at path characteristics, a genetic algorithm of an improved mutation operator is designed to solve the model; in the secondstage, aiming at different decision preferences of decision makers, an emergency rescue material scheduling multi-target model is constructed by taking the earliest emergency rescue development time,the minimum number of rescue participation points and the minimum number of rescue material requirements which are not met as targets, and a multi-target genetic algorithm NSGA-II is used for solving. The method has the characteristics of openness, flexibility, low calculation complexity and the like.

Description

technical field [0001] The invention belongs to the field of auxiliary decision-making for emergency rescue and relates to automation technology, in particular to a multi-objective two-stage emergency rescue material scheduling method for chemical accidents. Background technique [0002] Because chemical production, storage and transportation are mostly involved in hazardous chemicals, and chemical parks are mostly located in sensitive areas with developed economies and dense populations, chemical parks are in a high-risk state. In recent years, many major dangerous accidents in chemical industry parks have occurred, which have brought huge damage to people's lives and property. When faced with dangerous accidents in chemical industry parks, how to safely plan the driving path of rescue vehicles and rationally dispatch emergency rescue materials is of great significance to the timely development of rescue work. [0003] Many traditional dispatching methods for emergency res...

AI Technical Summary

Problems solved by technology

[0003] Many traditional dispatching methods for emergency rescue supplies only consider the path length factor in the path planning of rescue vehicles, and do not take into account the risk impact of the industrial park accident and the domino effect caused by the initial accident on the park and surrounding roads, which easily leads to planning errors. Rescue vehicle paths are at greater risk

In addition, because emergency rescue work is a systematic and complex scientific problem in practical problems, traditional emergency rescue material dispatching methods mostly use a single target as the rescue dispatching goal, such as the shortest rescue time and the fewest participating rescue points, so it is difficult to fully consider practical problems , may cause rescue work to be affected

Therefore, it is very difficult to dispatch emergency relief supplies
