It integrates forward and reverse flows where the collaborative supply chain takes place. Knowledge management is one important part of an organization that can improve the effectiveness of the processes within the organization. Knowledge sharing is significant in a collaborative supply chain since it affects the organizational performance and competitive advantage. The complexity in closed-loop supply chain can be managed better by encouraging knowledge sharing among the supply chain members. This paper presents a conceptual framework to implement knowledge sharing in a closed-loop supply chain management, for improving the CLSC members' performance. The success factors have been identified, and a framework has been presented, it consists of knowledge flows, management aspect and socio-technical aspect.

Many manufacturers are concerned that remanufacturing might cannibalize the new product’s sales. Recent development shows an increasing trend in selling products through non-traditional channels, such as a manufacturer’s direct channel or an e-channel. A pricing decision model is developed for short life-cycle products in a closed-loop supply chain that consists of the manufacturer, retailer, and collector. The new product is sold via traditional retail stores and the remanufactured product is sold via the manufacturer’s direct channel. There are two scaling factors introduced in the model: (1) customer acceptance of buying a remanufactured product (reman-acceptance); (2) customer preference for buying a remanufactured product via a direct channel (direct-channel-preference). The results show that implementing a separate channel can improve the total supply chain’s profit compared to the single-channel approach. It is also found that the two scaling factors influence both the pricing decisions and profits of supply-chain members.

There have been concerns on relatively rapid growth in population and increased quality of life despite limited natural resources and landfill capacity. Closed-loop Supply Chain (CLSC) is one of many approaches to mitigate the abovementioned disproportion. This article aims to study closed-loop supply chain by explaining the definition, description, pros and contras, relevance, case studies from literature, and potential research; such that its role as an agent of sustainable development can be recognized

While there has been very few pub-lished works that attempt to model remanufacturing decisions for products with short life cycle, we
believe that there are many situations where remanufacturing short life cycle products is rewarding eco-nomically as well as environmentally. The system that we model consists of a retailer, a manufacturer, and a collector of used product from the end customers. Two different scenarios are evaluated for the system. The first is the independent situation where each party attempts to maximize his/her own total profit and
the second is the joint profit model where we optimize the combined total profit for all three members of the supply chain. Manufacturer acts as the Stackelberg leader in the independently optimized scenario, while in the other the intermediate prices are determined by coordinated pricing policy. The results suggest that (i) reducing the price of new products during the decline phase does not give better profit for the whole system, (ii) the total profit obtained from optimizing each player is lower than the total profit
of the integrated model, and (iii) speed of change in demand influences the robustness of the prices as
well as the total profit gained.

Rapid development and innovation in science and technology have resulted in shorter product life-... more Rapid development and innovation in science and technology have resulted in shorter product life-cycle, especially in technology-based commodities like mobile phones and computers. Mounting wastes from such products have received increasing attentions from government, socie-ty, as well as industries for sustainability concerns. Numerous studies on remanufacturing have been found on durable goods, but only a few focusing on short life-cycle products. Even though several studies implied that successful remanufacturing requires products to have long useful life and stable technology, there are other findings that support remanufacturing of short life-cycle products. It is our intention to investigate remanufacturing of short life-cycle product. A literature review is conducted to study the pros and cons, life-cycle implication, and remanufacturing as-pects of short life-cycle products. Then we propose a framework that can be used to decide and plan the remanufacturing system. Furthermore, we conduct a survey to obtain descriptive analysis about the market potential for remanufactured short life-cycle products. The factors investigated are existence of demand, customer’s willingness to pay (WTP), and existence of green segment. The survey results show that low-end customers are the potential market segment for short life-cycle remanufactured product, because they have the highest preference toward remanufac-turing and 95% of them chose remanufactured product when the price is less than 40% of new product. It is also shown that green segment exists since 42%, 65%, and 47% of customers from high-end, low-end, and student sub-group respectively consider buying remanufactured products over new ones driven by their concern for the environment..

Responding to this trend, researchers in many parts of the world have conducted numerous studies in reverse logistics and reverse supply chain, that were considered separately from the forward channel of supply chains. Meanwhile, there are opportunities to create added values from product returns and to improve efficiency when both channels are considered in an integrated way, as a closed loop supply chain. On the other hand, remanufacturing is a very appealing option among product recovery processes that has potential to increase the value of product returns. However, the available literature and theories on closed loop supply chain with remanufacturing are still limited. This paper aims to provide a literature review that covers closed loop supply chain with remanufacturing to identify its characteristics based on previous works in this area. The review methodology is content analysis, classified into managerial aspects and technical aspects with their subsequent topics. Related literatures will be mapped under the abovementioned structures while identifying other important aspects that have potentials for further study. An outline of research opportunities will presented as a result of the review.
