Sustainable Processed Food Supply Chain Considering Price-Dependent Demand: A Case Study

In this paper, we considered a multi-objective multi-period model for a sustainable processed food supply chain. The model's objectives include economic objectives with profit maximization according to an economic index; social objectives calculated by social indexes that assesses the number of jobs created and regional development; and, environmental objectives, estimated through the measurement of carbon dioxide emissions and waste water treatment in the manufacturing sector. In addition, the proposed model attempted to determine the optimal location of production and distribution facilities and the flow rate among these facilities considering the type of delivery of perishable products, either directly from plant or indirectly from distribution centers with mechanized transportation systems. In this study, the demand for final products in the indirect shipment was estimated as price-dependent and in the direct shipment, it was fixed and predetermined. The proposed model is of the mixed-integer nonlinear programming type, so the model is linearized. Finally, the model is implemented in a processed food industry as a case study in Iran and is solved via the augmented e-constraint method.
