Optimization of Sustainable Forward and Reverse Food Supply Chain Network: A Case Study (TABAROK Food Products Factory)

Effective management of the food supply chain with a waste plan in mind will play a vital role in the company's success and bring numerous competitive advantages to the stakeholders. Perishability of food products affects economic, environmental and social aspects of food supply chains. Perishable goods impose additional costs on the inventory system due to the spoilage of the goods, so it becomes necessary to use a closed-loop supply chain. According to the literature, the consideration of inspection in food supply chain networks has not been investigated. The use of inspection in the production and distribution center can contribute significantly to the three dimensions of sustainability. Examining this issue as a forward and reverse food supply chain is a challenging issue. In this research, a sustainable forward and reverse supply chain network for food is presented, taking into account inspection in the production and distribution center to prevent the transfer of spoiled products to the next layer. To solve the model, the enhanced epsilon constraint method was used, which is able to provide Pareto solutions suitable for all the objectives of the decision makers, and it was investigated to show the efficiency of the model in the real world of TABAROK food products factory.
