TL;DR: In this paper, the authors discuss the challenges encountered by the remanufacturing sector and discuss how the Industry 4.0 revolution could help to effectively address these issues and unlock the potential of re-manufacturing.
Abstract: Remanufacturing is the process of bringing end-of-life products back to good-as-new. It plays a critical role in decoupling economic growth from growth in resource use, and in accelerating the circular economy. However, the uptake of remanufacturing activities faces obstacles. This paper reviews the challenges encountered by the remanufacturing sector and discusses how the Industry 4.0 revolution could help to effectively address these issues and unlock the potential of remanufacturing. Two case studies are included in this paper to exemplify how technology enablers from Industry 4.0 can increase efficiency, reliability, and digitization of the remanufacturing process.

TL;DR: In this paper, the authors identify and evaluate external barriers to remanufacturing in Indian electronic waste (e-waste) sector and provide insights and recommendations for policy planners involved in policy making.
Abstract: With industrialization and growth of population, implementation of sustainable technologies and environment protection has received a lot of attention. Remanufacturing is one of the sustainable technologies that provide environmental, economic and social benefits. Remanufacturing is “a comprehensive and rigorous industrial process by which a previously sold, worn, or non-functional product or component is returned to a “like-new” or “better-than-new” condition and warranted in performance level and quality” ( RIC, 2013 ). This research study aims to identify and evaluate external barriers to remanufacturing in Indian electronic waste (e-waste) sector. We applied grey-DEMATEL (Decision Making Trial and Evaluation Laboratory) approach to analyze external barriers to remanufacturing. The results indicate lack of channels to collect used products and customer unwillingness to return the products to be the most prominent barriers. Further, the results also depict uncertainty in quantity and timing of returned products to be the major causal barriers. The findings provide insights and recommendations for policy planners involved in policy making to boost remanufacturing in India. Primarily, government needs to bring awareness to customers regarding benefits of returning the used products and benefits of using remanufactured products through awareness campaigns, so that consumers also take initiative to protect environment. Channels to collects used products from customers also need to be developed.

TL;DR: It is shown that subsidizing remanufactured products alone may lead to undesired outcomes; however, the social optimum can be achieved by using a simple linear subsidy and tax scheme for all product versions.
Abstract: Trade-in remanufacturing is a commonly adopted business practice under which firms collect used products for remanufacturing by allowing repeat customers to trade in used products for upgraded ones at a discount price. This paper studies how customer purchasing behavior and remanufacturing efficiency affect the economic and environmental values of such a business practice. We demonstrate a new benefit of trade-in remanufacturing: it helps exploit the forward-looking behavior of strategic customers, which could be much more significant than the widely recognized revenue-generating and environmental benefits of remanufacturing. High remanufacturing efficiency does not necessarily benefit a firm. With overly high remanufacturing efficiency, product durability is so high that repeat customers are reluctant to trade in and upgrade their used products. When customers are highly strategic, trade-in remanufacturing creates a tension between profitability and sustainability: on one hand, by exploiting the intensiv...

TL;DR: In this article, the role of green attributes (energy saving, material saving and emission reducing) of remanufactured products and green certification play in influencing consumer perceptions was examined in terms of perceived value and trust.
Abstract: Manufacturers face several obstacles when marketing remanufactured products, and therefore need to be able to appeal to consumers’ motivational desires in order to influence their purchase decisions. Informed by regulatory focus theory, this research contributes to this area of research by examining the role that information regarding green attributes (energy saving, material saving and emission reducing) of remanufactured products and green certification play in influencing consumer perceptions. Potential consumers of remanufactured automobile parts in China were surveyed and the data were analyzed via structural equation modeling. The results suggest that energy saving, material saving and emission-reduction information regarding remanufactured products positively affect consumers’ perceived value and trust of remanufactured products. Green certification moderates the relationships between both the energy saving and material saving information and trust. This research improves understanding of how firms can influence consumer perception of remanufactured products, thus contributing to the discourse in the literature on remarketing of remanufactured products. The findings can be used to inform practitioners who seek to optimize the value proposition of achieving green certification and informing consumers about the environmentally friendly attributes of remanufactured products.

TL;DR: An improved multi-objective discrete bees algorithm is proposed to solve robotic disassembly line balancing problem and can find better solutions using comparable running time compared with the other optimization algorithms.
Abstract: Remanufacturing is an effective way to realize the reutilization of resources. Disassembly, as an essential step of remanufacturing, is usually finished by manual work which is low efficiency and high labor cost. Robotic disassembly provides an alternative way to reduce labor intensity and disassembly cost. Disassembly line is an efficient method to deal with end-of-life products on a large scale. Balancing the workload of robotic workstations is the main objective of robotic disassembly line balancing problem. In this paper, an improved multi-objective discrete bees algorithm is proposed to solve robotic disassembly line balancing problem. The feasible disassembly sequence is obtained by space interference matrix method. It is used to generate robotic disassembly line solution by robotic workstation assignment method. After that, the multi-objective robotic disassembly line balancing problem is proposed. With the help of efficient non-dominated Pareto sorting method, the improved multi-objective discrete bees algorithm is proposed to find Pareto optimal solutions. Based on a gear pump and a camera, the performance of the improved multi-objective discrete bees algorithm is analyzed under different parameters and compared with the other optimization algorithms. In addition, Pareto fronts of robotic disassembly line balancing problem are also compared with those of the other two cases. The result shows the proposed method can find better solutions using comparable running time compared with the other optimization algorithms.
TL;DR: A typology of re manufacturing is defined based on multiple decades of direct observations across various remanufacturing industries and identifies four distinct typological groupings based on the dimensions of a firm's strategic focus and product design philosophy.
Abstract: This manuscript defines a typology of remanufacturing based on multiple decades of direct observations across various remanufacturing industries. The manuscript also details how managers adapt their remanufacturing operations and strategies to the idiosyncrasies of the varied remanufacturing industries. The typology identifies four distinct typological groupings based on the dimensions of a firm’s strategic focus and product design philosophy. Before delving into typology and implications on strategic and design issues, the manuscript provides recent information on the current state of the remanufacturing industry based on governmental and industry reports. To assist readers who may be less familiar with the remanufacturing industry and closed-loop supply chains, the discussion also provides a brief overview of remanufacturing processes and the overall remanufacturing industry.

TL;DR: A solution method of branch-and-cut guided search algorithm is developed that is more effective when pickup requests are relative high and easier to solve when production or transportation costs are lower.
Abstract: This paper introduces a mixed integer programming model for production routing problems with reverse logistics and remanufacturing, which are closed-loop production routing problems addressed for the first time. A solution method of branch-and-cut guided search algorithm is developed. Computational results from instances adapted from benchmarks of production routing problems show that, the algorithm is more effective when pickup requests are relative high. The problem is also easier to solve when production or transportation costs are lower. The optimal decisions are insensitive to the location of remanufacturing depot whether it is geographically centered or centered with gravity.

TL;DR: In this article, a framework for a total life cycle cost model (TLCCM) is presented that aims to aid stakeholders in making decisions regarding all aspects of the product life cycle, and an application is explored that uses the model to determine post-recovery resource allocation into three closed-loop streams (Recycling, Remanufacturing and Reusing).
Abstract: The consumerism-driven, consumption-based linear economy is leaving a trail of economic, environmental, and societal challenges in its wake. The Circular Economy, a new economic framework, can be combined with the 6R-based elements of sustainable manufacturing in order to relieve these challenges by establishing a closed-loop material flow. To realize this ideal state, a total life cycle cost model (TLCCM) is needed to serve as the primary engineering economic model. Therefore, a framework for such a model is presented that aims to aid stakeholders in making decisions regarding all aspects of the product life cycle. It is intended that these stakeholders use this model in order to challenge the status quo of costly “green”-centric decisions and demand innovation in the overall process in order to realize a net positive total life cycle cost benefit alongside a balanced Triple-Bottom-Line (TBL). To illustrate how the TLCCM can be applied, an application is explored that uses the model to determine post-recovery resource allocation into three closed-loop streams (Recycling, Remanufacturing, and Reusing). An outlook for future research is then presented.

TL;DR: In this paper, the authors considered a three-echelon closed-loop supply chain consisting of a manufacturer, a third party and a retailer and compared and analyzed the optimal decisions under different scenarios by studying the impacts of marketing efforts and collection rate on the decision variables and concluded that the supply chain profit in centralized scenario is larger than decentralized one.
Abstract: Over the last few decades, closed-loop supply chain (CLSC) has received increasing attention due to concerns over the environment and social liability. Moreover, recycling and remanufacturing of the used products have been examined because of various factors such as concerns over the environment, lack of resources, government legislations. In this research, we consider a three-echelon closed-loop supply chain consisting of a manufacturer, a third party and a retailer. The manufacturer manipulates both manufacturing from raw materials and remanufacturing from the second hands products collected by third party simultaneously. We assume that the market demand depends on selling price and marketing efforts. First, we modeled the supply chain under centralized and decentralized policies and compared their performances using numerical examples. Then we compared and analyzed the optimal decisions under different scenarios by studying the impacts of marketing efforts and collection rate on the decision variables and concluded that the supply chain profit in centralized scenario is larger than decentralized one. Using a comprehensive sensitivity analysis, managerial insights are provided. Moreover, based on the derived results, from the perspective of remanufacturing process and consumers’ welfare, one can conclude that the manufacture-Stackelberg case is often the most effective scenario in CLSC.
TL;DR: In this paper, a two-stage stochastic bi-objective mixed integer programming model is proposed for the network design problem of a multi-product multi-echelon sustainable reverse logistics system under uncertainty, which aims at providing a set of Pareto solutions between profitability and environmental performance.
