Abstract
With the acceleration of industrialization in China, the output and transportation volume of hazardous chemical have increased dramatically. On the one hand, chemical has injected new vitality into the social and economic development. On the other hand, the safety of hazardous chemical has also been highlighted. According to statistics, hazardous chemical accidents in transportation links accounted for 35% of hazardous chemical accidents. Hazardous chemical transportation accident belongs to the low probability and serious consequence event. Once hazardous chemical accident occurs, it will cause great losses to people's lives, property and ecological environment. The hazardous chemical road transportation security question becomes the question which the people pay close attention to. In order to reduce hazardous chemical transportation accidents, we study the hazardous chemical transportation route optimization. In this paper, we propose an improved ant colony algorithm. The improved ant colony algorithm not only considers the transportation time and transportation risk, but also improves its algorithm settings. The improved algorithm is more suitable for optimizing the path of hazardous chemical. The experiments in this paper also verify the effectiveness and reliability of the improved algorithm.
