A simple system dynamics model of a traditional/closed loop supply chain system is investigated. Particularly, the effect of remanufacture, remanufacturing lead-time and the return rate on the inventory variance and bullwhip effect were studied. Our results clearly showed that the bullwhip in the closed loop supply chain is bigger than one in traditional supply chain and foreign to the collecti...

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...

With the development of the global economy, the emission of carbon dioxide and other greenhouse gases are getting larger and larger, which brings more and more serious environmental problems to nature that already has great pressure. The traditional enterprise development usually takes the cost minimization and the profit maximization as the enterprise management goal, at the expense of the env...

In recent years, comprehensive researches have provided ample support for the supply chains in the coordinated decision-making framework. However, the issue of closed-loop supply chain coordination considering various transportation modes has not yet been addressed in the literature. In this paper, a two-echelon closed-loop supply chain consisting of a manufacturer and a retailer is investigate...

Many authors and researchers cite Dell’s supply chain as a model of excellence, yet few look at the entire closed-loop supply chain and the prevalent inventory and logistics techniques that enable this complex process to work. The techniques reviewed include – postponement, modularity, vendor managed inventory, supply chain partnerships, and demand management. The analysis involves examining ho...

This research work develops a decision support model for a network design problem concerning a spare parts closed loop supply chain. It involves the formulation of an optimization model that takes on a mid to long-term planning perspective and covers decisions that have lasting and binding impact on organizational performance. These decisions include investment, location assignment, and invento...

Supply chain management and closed-loop supply chain management (CLSCM) have developed into established concepts in recent years. The related material cycles and product returns form an important part of all related processes with high potential for reducing environmental burden. The paper proposes a framework for (environmentally triggered) closed-loop supply chain management, spanning three d...

management model desirable to establish the life cycle of various commodities in different organizations is a closed-loop supply chain. in this paper, according to classic models in white and brown goods, a unified framework is used to implement in a military logistics company. it seems that using this model, improved lifecycle management, environmental conservation and improvement of services ...
