1 Distribution channel and licensing strategy choice considering consumer online reviews in a closed-loop supply chain
کانال توزیع و انتخاب استراتژی صدور مجوز با در نظر گرفتن بررسی های آنلاین مصرف کنندگان در یک زنجیره تامین حلقه بسته-2021
This research builds two-period game models to address the choice issues of the Original Equipment Manufacturer (OEM)’s licensing strategy and the Independent Remanufacturer (IR)’s distribution channel, considering consumer online reviews in a closed-loop supply chain. In both periods, the OEM sells new products by the direct distribution channel. In period 2, the OEM determines the licensing strategy (the fixed or royalty fee) to authourize the IR to remanufacture, and then the IR chooses the distribution channel (direct or indirect) for remanufactured products. Interestingly, our results show that the IR prefers the direct channel when the remanufacturing cost is smaller. And the obtained willingness-to-pay (WTP) from consumer online reviews has a positive impact on the threshold value of the remanufacturing cost. Moreover, we find that the OEM’s licensing strategy choice depends on the sizes of the fixed licensing fee and the obtained WTP. The OEM will choose the royalty licensing strategy to the IR who has chosen the direct channel, when the fixed fee and the obtained WTP are smaller. Finally, we find the optimal royalty fee, numerically examine the impact of the interaction among these factors on consumer surplus and social welfare, and relax the basic assumption to show the robustness of our model.

2 Analyzing a closed-loop sustainable supply chain with duopolistic retailers under different game structures
تجزیه و تحلیل یک زنجیره تامین حلقه بسته پایدار با خرده فروشان دوپولیستی تحت ساختارهای مختلف بازی-2021
This article investigates a closed-loop supply chain consisting of a manufacturer, two suppliers and two competitive retailers. One retailer sells manufactured products whereas the other retailer sells remanufactured products and takes up corporate social responsibility (CSR). One supplier supplies used products or cores for remanufacturing while the other supplier supplies fresh raw materials for manufacturing new product. The manufacturer sells both new and remanufactured products with different wholesale prices. The paper analyzes the two competitive retailers different game strategies when the manufacturer acts as the Stackelberg leader. It is shown that remanufacturing is a good policy to adopt for the whole supply chain, not only for economical benefits but also for environmental sustainability. Optimal decisions of the proposed closed-loop supply chain and its members are also supported by a numerical example. Finally, sensitivity analysis is carried out with respect to key model- parameters.© 2021 CIRP.

3 Production decisions of a closed-loop supply chain considering remanufacturing and refurbishing under government subsidy
تصمیمات تولید یک زنجیره تامین حلقه بسته با توجه به بازسازی و نوسازی تحت یارانه دولت-2021
Remanufacturing and refurbishing, as two essential strategies in the sector of reverse logistics, play a vital role in the area of sustainable development. With the increasing concerns on the environment friendly supply chain by the general public, we construct two remanufacturing models dominated by the original equipment manufacturer (OEM) and the independent remanufacturer (IR) based on the auto parts market which provides new products, remanufactured products and refurbished products. Considering the remanufacturing subsidy and the market environment parameters, we analyze the full-remanufacturing and partial-remanufacturing using the Stackelberg and Cournot duopoly game models. We then obtain the equilibrium strategies for each of these scenarios. We further carry out sensitivity analysis for the two remanufacturing models and investigate the impact of the remanufacturing subsidy on these two models. The findings in this paper enable us to compare the remanufacturing modes and show how the equilibrium outcome depends on the key model parameters. In the comparison and numerical analysis, they are revealed that (i) the improvement on the quality level of the refurbished products is always unfavorable to the quality level and the production quantity of both the new and the remanufactured products, especially in the OEM remanufacturing model; (ii) subsidy is ineffective in the IR remanufacturing mode when the remanufacturing cost is low; (iii) the IR remanufacturing outperforms the OEM remanufacturing in both economic benefits and social welfare, when the cost of remanufacturing and the customer willingness to pay for remanufacturing products are low, and the quality of refurbished products is high. These findings have potential implications for enterprise remanufacturing production and government policy-making in complex market environments.

4 Optimizing inventory decisions for a closed–loop supply chain model under a carbon tax regulatory mechanism
بهینه سازی تصمیمات موجودی برای یک مدل زنجیره تامین حلقه بسته تحت مکانیزم نظارتی مالیات کربن-2021
Green supply chain management encompasses every level of the supply chain. The core green supply chain management strategies include closed–loop manufacturing and reduction of carbon footprint. These strategies enable firms to improve their environmental profile and to comply with environmental regulations. This paper deals with a supply chain system integrating manufacturing, remanufacturing and repair activities (closed–loop manufacturing) to face a time-varying demand under the regulatory framework for carbon tax. Initially, the total cost of the system is provided and then a mixed integer nonlinear programming problem is formulated aiming to determine the optimal policy i.e. the manufacturing, remanufacturing and repairing cycles. After decomposing the original problem into two pure manufacturing and remanufacturing sub-problems, the existence of their optimal solution is proved and then a simple method, which relies on a finite search scheme, is used to determine the overall optimal solution. Through a variety of numerical examples and a sensitivity analysis, the effect of the different system parameters on costs and environmental efficiency are provided, such as: returns, carbon emissions generated per activity and rates of any activity. The main result of this analysis indicates that the proposed model is fairly robust to the parameters’ changes, however the tax on carbon emissions has a seriousimpact on the system optimal cost.

5 Remanufacturing with upgrade PSS for new sustainable business models
تولید مجدد با PSS ارتقا یافته برای مدل های جدید تجاری پایدار-2020
Starting from mid ‘90s, Eco-efficient Product Service Systems (PSSs) were indicated in literature as enablers toward a more sustainable and resource-efficient industry through re-use and remanufacturing. In this regard, academicians and practitioners outlined several advantages (environmental and economic) but also many barriers hindering their implementation, such as market acceptance and economic sustainability. Thus, the diffusion of re-use and remanufacturing PSS is currently limited and mainly restricted to markets accepting also out-dated products (e.g. B2B or emerging countries). To cope with this limitation, product upgrade in re-manufacturing was recently introduced. Upgrade cycles allow embedding technological innovation into products while remanufacturing, thus reaching advanced performances and satisfying evolving customers’ preferences over time. If coupled with the offering of advanced services, remanufacturing with upgrade would open the way to new disruptive PSSs able to revolution customers’ consumption behaviour, as well as the manufacturing business model of companies. The new remanufacturing with upgrade business models will make remanufacturing one of the main pillars of companies’ business value generation, allowing improved management of technology cycles and of products obsolescence. Thus, overall economic and environmental benefits will be maximised. However, the implementation of such business models represents a challenge for manufacturers. The evolution from a pure manufacturing towards a manufacturing/remanufacturing company, together with the transition from a product to a service-based offering, entails considerable changes in all the business model variables. Drawing on the theory of business model innovation process, incremental or radical innovation paths can be hypothesised for this transition. Despite the focus of recent research on Product Service Systems and on Circular Economy, remanufacturing-with-upgrade business models are rarely cited in literature and there is limited empirical evidence of companies having embraced them. To set the research framework in alignment with previous theory, this paper proposes a structured definition and configuration of innovative remanufacturing-with-upgrade business models. By looking at existing examples of companies having undertaken this type of business model innovation, different typologies of remanufacturing and upgrade business models are proposed. Companies were classified according to the identified PSS typologies and conclusions are derived, together with future research perspectives.© 2018 CIRP.

6 Make at home or abroad? Manufacturing reshoring through a GPN lens: A Norwegian case study
در داخل یا خارج از کشور درست کنید؟ تولید مجدد محصولات از طریق لنز GPN: مطالعه موردی نروژی-2020
The explorative paper investigates the drivers for the emerging trend of manufacturing reshoring from low- to high-cost locations. To date research on the reshoring phenomenon has been dominated by micro-level analyses of firms in supply chain management and reported in international business literature. The paper introduces reshoring as a research topic to the economic geography research field, arguing that it connects with the broader topic of regional development. To provide a better understanding of the reshoring phenomenon and to test the applicability of the global production network (GPN) framework in the analysis of the phenomenon, the authors analyse the reshoring of nine of Norwegian manufacturing firms. With the multiscalar lens provided by the GPN framework, the authors find that the implementation of advanced manufacturing technologies is a driver for manufacturing reshoring, but only when matched with key regional assets such as automation knowledge and competence, key human capital, and region-specific manufacturing competence. Additionally, reshoring decisions are influenced by extra-regional factors such as changes in the global economy and market fluctuations. Furthermore, the paper provides a refined conceptualization of strategic coupling processes by including acts of disinvestments and reinvestments performed by actors within global production networks. Accordingly, the authors advocate a more nuanced understanding, defined as partial coupling processes, in contrast to the pre- dominant understanding of coupling processes as ruptures. This refined conceptualization provides enhanced analytical purchase when studying the reshoring phenomenon, as it illuminates the complexity of firms’ pro- duction and sourcing strategies and the resulting implications for the economic landscape.

7 Big data driven Hierarchical Digital Twin Predictive Remanufacturing paradigm: Architecture, control mechanism, application scenario and benefits
داده های بزرگ مبتنی بر الگوی پیش بینی تولید دوقلوهای پیش بینی شده دوقلو سلسله مراتبی: معماری ، مکانیسم کنترل ، سناریوی برنامه و مزایا-2020
Remanufacturing is deemed to be an effective method for recycling resources, achieving sustainable production. However, little importance of remanufacturing has been attached in PLM. Surely, there are many problems in implementation of the remanufacturing strategy, such as inability to effectively reduce uncertainty, lack of product multi-life-cycle remanufacturing process tracking management, lack of smart enabling technology application in the full lifecycle that focusing on multi-life-cycle remanufacturing. After analyzing the reasons, through integrating smart enabling technologies, a new PLM paradigm focusing on the multi-life-cycle remanufacturing process: Big Data driven Hierarchical Digital Twin Predictive Remanufacturing (BDHDTPREMfg) is proposed. And the definition of BDHDTPREMfg is proposed. A big data driven layered architecture and the hierarchical CPS-Digital-Twin(CPSDT) reconfiguration control mechanism of BDHDTPREMfg are respectively developed. Then, this paper presents an application scenario of BDHDTPREMfg to validate the feasibility and effectiveness. Based on the above application analysis, the benefits of penetrating BDHDTPREMfg into the entire lifecycle are demonstrated. The summary of this paper and future research work is discussed in the end.

8 Closed-loop supply chain models with product take-back and hybrid remanufacturing under technology licensing
مدل های زنجیره تامین بسته با بسته بندی محصول و تولید مجدد محصول تحت مجوز تکنولوژی-2017
The economical and environmental benefits of remanufacturing have been widely recognized in literature and practical life. In this paper, we consider a closed-loop supply chain consisting of a manufacturer, a distributor and a third party, who are engaged in producing remanufactured products. Additionally, the manufacturer as the channel leader tends to cooperate with the distributor and the third party by technology licensing. Specifically, we develop three hybrid remanufacturing models: (1) the manufacturer collects and remanufactures used products by herself (Model M), (2) the manufacturer remanufactures a fraction of used products and licenses the distributor to remanufacture while the distributor collects used products (Model MD), (3) the manufacturer remanufactures a fraction of used products and licenses the third party to remanufacture while the third party collects used products (Model MT). We discuss the impacts of remanufacturing ability on the chain members and environmental sustainability, and also analyze the role of saving unit cost in the remanufacturing process. Moreover, we apply the Stackelberg game to attain the equilibrium strategies from the perspective of chain members profits. The profit of the manufacturer, the distributor and the third party reaches the most in Model M, Model MD and Model MT, respectively. These results can help achieve an optimal approach of hybrid remanufacturing in a closed-loop supply chain.
