The transit and storage of hazardous chemicals are harmful. A distributed decision model for hazardous chemicals is developed in this study, with the time window established, to improve the efficiency of transportation and storage. The route, mode, time, and volume of each demand can be determined by this model. The model minimizes the total transportation risk and cost. The model is divided into two parts, and the corresponding ant colony algorithm is designed and achieved. The feasibility and efficiency of the model are illustrated through a numerical example with eight transfer nodes, six origin–destination (OD) demands, and multiple transportation mode alternatives. The developed model provides an effective approach for hazardous chemical substance transportation.
