Abstract:Construct a closed-loop supply chain composed of a new key component supplier and an original equipment manufacturer (OEM) responsible for remanufacturing of old key components, both of which are financially constrained. There are three alternative financing strategies: separate bank financing (SBF), bank financing with supplier’s delay-in-payment (BF-with-SDP), and bank financing with OEM’s advance payment (BF-with-OAP). The former one is regarded as non-collaborative financing, while the latter two are collaborative. Through numerical analysis, we analyze the remanufacturing strategies under non-collaborative/collaborative financing, and the collaborative financing strategies under OEM remanufacturing. We find that: collaborative financing is always more conducive to manufacturing/remanufacturing and contributes to the overall performance of the supply chain; to deal with the conflict in financing preferences, supplier should actively seek to build contract with OEM based on incentive compatibility rule; how to choose between BF-with-SDP and BF-with-OAP strategies will depend on the guarantee ratio allowed by the supplier; compared with BF-with-OAP strategy, BF-with-SDP strategy can better realize the synergy of promoting remanufacturing production, improving supply chain performance, and reducing the risk of bank default losses.
