Reverse supply chains are receiving increased attention in both academia and practice to address business and environmental sustainability opportunities. As few organizations are adept at both forward and reverse supply chains, subcontracting various activities is imperative. Forging temporary partnerships as a virtual enterprise to take advantage of a short-term market opportunity is one avail...

Along with forward supply chain organization needs to consider the impact of reverse logistics due to its economic advantage, social awareness and strict legislations. In this paper, we develop a system dynamics framework for a closed-loop supply chain with fuzzy demand and fuzzy collection rate by incorporating product exchange policy in forward channel and various recovery options in reverse ...

University bookstores have a complex multi-product, multi-supplier supply chain with complex channel relationships such as product substitution, random yields, reverse logistics and returns, and risk sharing contracts. Supply chain efficiency is important to the bookstore due to low overall profit margin. The used book buyback activity is an example of reverse logistics with random yield with s...

background: hox genes are well-known transcription factors that play essential roles in directing embryonic development. tgifly is a y-linked homeobox gene that was originally identified by virtue of its expression in adult testis. the functions of tgifly in normal and abnormal development are unknown. methods: to investigate the potential roles of tgifly gene in the infertile males, a semi-nes...

globalization, increasing the global regulations of governmental and non-governmental organizations and customers’ request regarding to environmental compliance issues have led to organizations considering the green supply chain management to improve the environmental and economical performance. in order to maximize the efficiency of energy consumption and resources across the supply chain, gre...

At the strategic level, closed-loop supply chain (CLSC) management involves long-term decisions regarding the location and capacity allocation of forward/reverse logistics facilities, the assignment of products to facilities, and the distribution of products between facilities and their end users or suppliers. Both demand and return handling must be taken into account, and the overall problem b...

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...

Environmental and economic issues have significant impacts on reverse supply chain management and are thought to form one of the developmental cornerstones of sustainable supply chains. Perusal of the literature shows that a broad frame of reference for reverse supply chain management is not adequately developed. Recent, although limited, research has begun to identify that these sustainable su...

Although many quantitative models have been reported in the literature for designing a supply chain, none of them address issues that are crucial for the supply chain to successfully operate in a closedloop. To that end, we examine the following: (i) selection of economical products to process, (ii) identification of efficient production facilities in the region where the supply chain is to be ...
