Abstract
Hazardous chemical has the characteristics of easy explosion, toxicity, corrosiveness etc. These characteristics make dangerous chemical not only causing harm to the human body, but also polluting the environment. With the development of the global economy, the application of hazardous chemical is more and more widely. Compared with the traditional supply chain, the hazardous chemical supply chain has more potential factors and faces more risks. These potential risks threaten life and property safety. This is also a great challenge to the management of hazardous chemical, especially the management of the hazardous chemical supply chain. In order to assess the risk of hazardous chemical supply chain, we propose an improved AHP algorithm in this paper. This algorithm combines the PSO algorithm with AHP to improve the traditional AHP algorithm. After that, we apply the improved AHP algorithm to assess the risk of the hazardous chemical supply chain and get good results.
