Linking forward and reverse supply chain investments: The role of business uncertainty

This paper explores managerial efforts in reverse supply chains (RSC), where the focus is on the capture and exploitation of used products and materials. The RSC can potentially reduce negative environmental impacts of extracting virgin raw materials and waste disposal. If so, investment in the reverse supply chain should not be made in isolation, but instead must be integrated with investments selected to improve the forward supply chain. After defining and operationalizing these constructs, a survey of plant managers was used to empirically assess the linkages between supply chain investments, organizational risk propensity (i.e., willingness to take risk) and business uncertainty. Reverse supply chain investment had two primary dimensions: reconditioning (i.e., high-value recovery) and recycling and waste management (i.e., low- or no-value recovery). Ongoing investment in the forward supply chain was significantly related to investment in recycling and waste management, but not to investment in reconditioning. Moreover, risk propensity was found to mediate the relationship between the external business uncertainty and investment in the forward and reverse supply chain.

Decision analysis and coordination of dual supply chain with retailer's offline return service and online reviews

Based on the centralized and decentralized decision-making cases, this study constructs a dual-channel supply chain game model that considers offline return service and online reviews, and explores the pricing decisions and benefits of supply chains under the dual influence of return service level and online reviews. The impact of return rate, return service level and perceived quality of online reviews on optimal supply chain decisions and profits are further analyzed. Finally, considering the phenomenon of double marginalization in the supply chain, this study coordinates the supply chain based on the benefit-sharing contract coordination model to achieve Pareto improvement. The research shows that: The manufacturer's optimal wholesale price, the optimal online selling price and the retailer's optimal offline price are positively correlated with the perceived quality of online reviews and the level of return service. Compared with the return service level, the perceived quality of online reviews has a greater impact on the overall profit of the supply chain. Under the dual influence of the perceived quality of online reviews and the level of return service, the supply chain profit in the centralized model is better than that in the decentralized model. The coordination model can effectively coordinate the supply chain. Moreover, when the sharing ratio of manufacturers is obviously lower than that of retailers, the coordination effect is better at this time.

Supply chain decisions and coordination in the presence of an imperfect spot market

This study considers a supply chain consisting of a commodity supplier and a final product manufacturer with uncertain demand. In addition to purchasing from the supplier through a forward contract, the manufacturer can adjust their inventory by trading the commodity in an online spot market after observing the actual demand. However, the spot market is imperfect in that transactions cannot be certainly realized and come with additional transaction costs. Furthermore, the spot price is volatile such that overly relying on the spot market is unwise. To investigate how the spot market affects the decisions and coordination in a supply chain, we develop a game-theoretical model incorporating spot trading. We derive the optimal ordering decision in a centralized supply chain, as well as the supplier's and manufacturer's equilibrium pricing and ordering decisions in a decentralized supply chain. The impact of the imperfect spot market on the optimal decisions and profits is analyzed. This study also demonstrates how the supply chain can be coordinated in the presence of an imperfect spot market. Finally, a numerical analysis is performed to examine the analytical results. Our results indicate that the spot market can generally improve the performance of the centralized supply chain and benefit the manufacturer in the decentralized one. However, it can be detrimental to the supplier. The supply chain can be coordinated by a revenue-sharing contract, and both parties' profits can be improved. Our findings suggest that the manufacturer could take advantage of the spot market, and the supplier should attempt to integrate or coordinate the supply chain to share the benefits of spot trading.
