closed-loop supply chain network design is a critical issue due to its impact on both economic and environmental performances of the supply chain. in this paper, we address the problem of designing a multi-echelon, multi-product and capacitated closed-loop supply chain network. first, a mixed-integer linear programming formulation is developed to maximize the total profit. the main contribution...

In recent years, sustainability concept has been introduced to many fields including management, technology, and supply chain (SC). The most accepted definition for Sustainable Supply Chain Management (SSCM) would be one where all consumer products are created, used, and recycled or disposed of in the Closed loop Method. Closed Loop Supply Chain Management (CLSCM) refers to all forward Logistic...

Modeling and optimal solving of supply chain management problems lead to efficient decision making in strategic planning and supply chain operations, resulting in a competitive advantage. Today, with the planning of a sustainable supply chain, in addition to achieving economic goals, it is possible to meet social and environmental objectives and considerations. This research deal with sustainab...

Environmental consciousness has become critical in the design and operations management. In recent years, the sort of issues that have come to light and drawn the attention of managers has extended staggeringly. Sustainable development is a significant component of growing interest for managers who have to address with social and environmental issues related to the own company as well as their ...

this paper proposes a new mixed integer programming model for multi-item capacitated lot-sizing problem with setup times, safety stock and demand shortages in closed-loop supply chains. the returned products from customers can either be disposed or be remanufactured to be sold as new ones again. due to the complexity of problem, three meta-heuristics algorithms named simulated annealing (sa) al...

Sustainable product lifecycle systems are attracting increasing attention because of cost competition, resource constraints and environmental issues. Short lifecycle products, such as consumer and defense electronics, are of particular concern. We formulate a closed-loop supply chain with Stochastic Dynamic Programming method. By applying the concept of a sustainable product lifecycle, guidelin...

green supply chain management is an environmental approach in supply chain management that aims to decrease ecological risks in products’ life cycle. closed-loop supply chain by collecting and recycling the harmful production in nature attempts to achieve this goal. in this paper, due to different strategies in collecting products, several pricing models in two-echelon closed supply chain are p...
