Abstract
In today's competitive world, companies need to effectively manage their supply chains in changing market conditions, and they are also obliged to compensate for their environmental damages. In this research, a two-echelon multi-product multi-period supply chain network with production and distribution centers has been modeled with three objectives: minimizing logistic costs, delivery time, and CO2 emission costs. Customer demand parameters, available levels of human and machinery resources are uncertain and considered as fuzzy numbers. Additionally, the possibility of using subcontracting services for production and transportation operations at a higher cost exists. The main innovation of this research is modeling the possibility of using different transportation systems and considering their pollution, and using a novel fuzzy multi-criteria goal programming method (proposed in 2018) for solving the problem. Real data from "Daya Technology" company has also been used for case study and model evaluation.
