Reverse logistics (RL) and closed-loop supply chains (CLSC) have recently received enormous attention due to growing environmental concerns and legislations coupled with the lucrative business potential. The main purpose of this paper is to develop a closed-loop supply chain network design model capable of recovering glass containers. A multi-period multi-product mixed-integer linear programmin...

This paper studies inventory management in a two echelon supply chain with stochastic demand and lost sales. The optimal policy is evaluated and compared with the competitive solution, the outcome of a game between a supplier and a retailer in which each ...rm attempts to maximize its own pro...t. It is shown that supply chain pro...t in the competitive solution is always less than the optimal ...

In the recent decade, special attention is paid to reverse logistic due to economic benefits of recovery and recycling of used products as well as environmental legislation and social concerns. On the other hand، many researches claim that separately and sequential planning of forward and reverse logistic causes sub-optimality. Effective transport activities are also one of the most important c...

One of the most strategic and the most significant decisions in supply chain management is reconfiguration of the structure and design of the supply chain network. In this paper, a closed loop supply chain network design model is presented to select the best tactical and strategic decision levels simultaneously considering the appropriate transportation mode in activated links. The strategic de...

the primary purpose of this paper is to highlight for the research community and practitioners the various aspects of using vmi-type supply chains in today’s business environment as well as a number of directions for future studies. in this regard, fifty articles published in major international journals, beginning in 1995, which contribute to the vmi-type supply chains are reviewed via a syste...

In this paper we consider a periodic review order-up-to inventory system with capacitated replenishments, lost sales and zero lead time. We consider discrete demand. It is shown that the initial stock levels of the different review periods form aMarkov chain andwe determine the transitionmatrix. Furthermore we study for what probabilitymass functions of the review period demand theMarkov chain ...

We address the value of information (VOI) sharing in the context of a two–echelon, serial supply chain with one retailer and one supplier that provides a single perishable product to consumers. We evaluate information sharing under two supply chain structures where the retailer shares it inventory level and replenishment policy with the supplier. In the first structure, referred to as Decentral...

We consider a single-location inventory system with periodic review and stochastic demand. It places replenishment orders to raise the inventory position—that is, inventory on hand plus inventory in transit—to exactly S at the beginning of every period. The lead time associated with each of these orders is random. However, the lead-time process is such that these orders do not cross. Demand tha...
