Proposing a Multi-objective Model for Ground Transportation of Hazardous Materials in the Hub Network (Case Study: National Iranian Oil Products Distribution Company)

The purpose of this study is to provide a multi-objective model for ground transportation of hazardous materials in the hub network that tries to minimize the costs of transportation and construction of the hubs and the links, considering the existing risk in the hazardous materials transportation. The problem with the proposed Hub Location model will be solved using the real data of National Iranian Oil Products Distribution Company and applying the Global Criterion Method. Then the sensitivity analysis of the model's results on some parameters is performed. Considering the results of the model for 10 hubs, Chaharmahal and Bakhtiari was chosen as the new hub location. The supply of oil products to each of the areas was also provided. Hazardous materials as raw materials or strategic products in different industries play an important role in the industrial development of the country. Transportation of hazardous materials is very important due to their perilous nature and consequences. On the other hand, the proper design of a transportation network and optimal distribution of the products from production sources to consumers can reduce the costs of production and result in the optimum consumption of energy.
