Mathematical Modeling Using Dempster-Shafer Theory to Integrate Optimization of Location, Inventory and Routing in Design of Multilevel and Multi-product Three-Level Supply Chain Design

Transportation goods seems a very simple matter. The wider the supply and distribution network, the different the number of customers and suppliers, and the more restrictions on material flows, information and finance, the more specialized the science of movement becomes and the need for intermediaries to facilitate the flow of materials and information is felt. Organizations around the world are looking for tactics and techniques to survive in today's turbulent competitive environment. One of these approaches is outsourcing supply chain logistics operations in the form of third party logistics companies. Third party logistics services companies or 3PL are companies that outsource their production or service organizations or all of their logistical affairs. The main purpose of the researchThe present is the development of a mathematical model for the problem of selecting and evaluating 3PL companies based on a competitive approach in uncertain conditions in the automotive industry in order to minimize costs. Current research is tailored to the survey descriptive method in terms of the applied purpose of the present study and the research method has been adjusted based on its stages. The uncertainty in the real business environment, supply and demand parameters in the research modelThe triangular fuzzy numbers were considered in the model and after de-fuzzy, the model was solved using Lingo software and the results were analyzed. The results show that with the production of 4000,000 pieces of products in Pars Khodro Company, the maximum use of recycled scrap is 1714,000 pieces and the minimum use of first-hand scrap will be 2286,000 pieces.
