Designing a logistic network is a strategic and critical problem that provides an optimal platform for the effective and efficient supply chain management. In this research, we address the application of fuzzy sets to design a multi-product, multi-period, closed-loop supply chain network. The presented supply chain includes three objective functions: maximization of profit, minimization of deli...

The importance of considering forward and backward flows simultaneously in supply chain networks spurs an interest to develop closed-loop (CLSCN). Due the expanded scope chain, designing CLSCN often faces significant uncertainties. This paper proposes a fuzzy multi-objective mixed-integer linear programming model deal with uncertain parameters CLSCN. two objective functions are minimization ove...

In a global economy, an efficient supply chain as a main core competency empowers enterprises to provide products or services at the right time in the right quantity, at a low cost. This paper is to plan a single product, multi-echelon, multi-period closed loop supply chain for high-tech products (which have continuous price decrease). Ultimately, considering components rated to procurement, pr...

Today, sustainable development is one of the important issues in regard to the economy of a country. This issue magnifies the necessity for increased scrutiny towards issues such as environmental considerations and product recovery in closed-loop supply chains (CLSCs). The most important motivational factors influencing research on these topics can be considered in two general groups: environme...

recovery of used products is receiving much attention recently due to growing environmental concerns.in this paper, we address the carbon footprint basedon problem arising in closed-loop supply chain where returned products are collected from customers. these returned products can either be disposed or be remanufactured to be sold as new ones again. here, we formulate a comprehensive closed-loo...
