Item MULTIMODAL TRANSPORTATION OPTIMIZATION OF MULTI-COMMODITY HAZARDOUS MATERIALS WITH A LEXICOGRAPHIC GOAL PROGRAMMING MODEL(2022-06-22) GÜZEY, Refika Ruzin; BAÇ, UğurThere are many hazardous materials defined in different classes with their chemical and physical properties, and they are used as raw materials in many products produced in the production sector. Those who use and transport these substances should aim at the minimum risk that ensures the implementation of legal rules, in addition to the objectives such as the minimum cost and time stipulated in their businesses. Highway is widely used for hazardous materials in our country. In the literature, the efficiency of different types of multimodal transport has been mentioned. There are multi objective studies, mainly with minimum cost and minimum risk, in which multi-modal transportation is used for the transportation of hazardous materials. These studies mostly focused on the fuel group, which is one of the hazardous materials. In this study, minimizing the cost, risk and ultimately the transportation time in transportation between the hazardous materials producers and the needy people in different cities are discussed. In addition, it has been evaluated that air transportation, which does not have a priority of use, is an option for the multi-modal transportation of hazardous materials that are outside the fuel group and can be transported by plane. Goal programming model is used to solve the problem. The effectiveness of the proposed model was evaluated by coding in the CPLEX solver with a case study.
