doi:10.3969/j.issn.1007-7375.2020.05.014

Abstract

Abstract: Emergency material dispatching is the key content of emergency rescue work for hazardous chemicals accidents. The accident of dangerous chemicals will cause environmental pollution to the surrounding areas, so the problem of emergency material dispatching should consider multiple objectives. Aiming at the characteristics of emergency material dispatching in hazardous chemicals accidents, a multi-objective model of continuous consumption emergency material dispatching is established. The objective of the model is to minimize the shortage loss, the shortest dispatch time and the minimum total environmental risk, considering the constraints of material quantity limitation and rescue time limitation at rescue point. NSGA II genetic algorithm is used to solve the model. For the solution results, the ranking method approaching the ideal solution is used to select. The calculation results show that the multi-objective model optimization scheme has more advantages than the single-objective model optimization scheme, and the algorithm is reasonable and feasible.
