“…Hence, to minimize the number of scenarios, the fast forward selection algorithm was used, and the accelerated L-shaped method was implemented in C++ to solve the model. Polat and Gungor [28] developed a MILP model to manage activities on the waste of electrical and electronic equipment. The model considered different damage levels in returned EOL products.…”

The increased awareness of environmental sustainability has led to increasing attention to closed loop supply chains (CLSC). The main objective of the CLSC is to capture values from end-of-life (EOL) products in a way that ensures a business to be economically and environmentally sustainable. The challenge is the complexity that occurrs due to closing the loop. At the same time, considering stochastic variables will increase the realism of the obtained results as well as the complexity of the model. This study aims to design a CLSC for durable products using a multistage stochastic model in mixed-integer linear programming (MILP) while considering uncertainty in demand, return rate, and return quality. Demand was described by a normal distribution whereas return rate and return quality were represented by a set of discrete possible outcomes with a specific probability. The objective function was to maximize the profit in a multi-period and multi-echelon CLSC. The multistage stochastic model was tested on a real case study at an air-conditioning company. The computational results identified which facilities should be opened in the reversed loop to optimize profit. The results showed that the CLSC resulted in a reduction in purchasing costs by 52%, an annual savings of 831,150 USD, and extra annual revenue of 5459 USD from selling raw material at a material market. However, the transportation cost increased by an additional annual cost of 6457 USD, and the various recovery processes costs were annually about 152,897 USD. By running the model for nine years, the breakeven point will be after three years of establishing the CLSC and after the annual profit increases by 1.92%. In conclusion, the results of this research provide valuable analysis that may support decision-makers in supply chain planning regarding the feasibility of converting the forward chain to closed loop supply chain for durable products.

“…The implementation of closed-loop supply chain (CLSC) strategies can save production costs for manufacturers while improving the environmental and social benefits of the supply chain [1][2][3]. In recent years, driven by the economic benefits from remanufacturing and government regulations, it is observed that an increasing number of well-known manufacturers and retailers have implemented the CLSC strategies, which has played a significant role in achieving harmonious development of economy, society and, environment.…”

How Retailer Co-Opetition Impacts Pricing, Collecting and Coordination in a Closed-Loop Supply Chain

et al. 2021

The cooperative and competitive (i.e., co-opetition) behavior between retailers plays a significant role in the development of operations and marketing strategies in a supply chain. Specifically, retailers’ co-opetition relationship pivotally influences the sustainable performance in a closed-loop supply chain. This study examines the impact of retailer co-opetition on pricing, collection decisions and coordination in a closed-loop supply chain with one manufacturer and two competing retailers. Based on observations in some industries (e.g., electronic manufacturing, fabric and textile, etc.), the cooperative and competitive relationships between retailers can be classified into the following three different modes: Bertrand competition, Stackelberg competition, and Collusion. In this paper, we establish a centralized and three decentralized game-theoretic models under these three co-opetition modes and characterize the corresponding equilibrium outcomes. The results indicate that the Bertrand competition mode yields the highest return rate, which is also superior to the other two modes for both the manufacturer and the supply chain system in terms of profitability. However, it can be shown that which mode benefits the retailers would depend on the degree of competition between the retailers and the relative remanufacturing efficiency. Interestingly, we find that the retailer’s first-move advantage does not necessarily lead to higher profits. In addition, we design a modified two-part tariff contract to coordinate the decentralized closed-loop supply chains under three different retailer co-opetition modes, and the results suggest that the optimal contractual parameters in the contracts highly rely on the remanufacturing efficiency and the competition degree between the two retailers. Several managerial insights for firms, consumers and policy makers are provided through numerical analysis.

Despite extensive research on e‐waste management, the integrative responsibilities of multi‐stakeholders and the dependency on technology remain underexplored. This study aims to develop an integrative multi‐stakeholder responsibility model to advance the net‐zero goal in e‐waste management. Following the PRISMA protocol, we conducted a systematic review of 99 articles. The review revealed three themes of stakeholder responsibility, four performance measure categories, three e‐waste solutions, and four roles of smart technologies. These insights informed the development of a conceptual model to enhance environmental performance in e‐waste. The proposed model emphasises critical attributes of multi‐stakeholder relationships, including partnership, shared responsibility, inclusiveness, and transparency; it offers practical guidance for multi‐stakeholders in prioritising efficient and mature technologies to be adopted and diffused, enabling effective e‐waste management. Our study extends stakeholder theory from an organisation‐centric to a problem‐based perspective, highlighting its practical implications for effective e‐waste management and suggesting future research directions for sustainability.
