Reverse supply chain management with dual channel and collection disruptions: supply chain coordination and game theory approaches

In reverse supply chain (RSC) systems, disruptions in the collection process of used items may negatively influence the efficiency of RSC participators. Inspired by a real case study, this paper contributes to the RSC systems coordination literature by analyzing the effect of collection disruptions on the efficiency of an RSC system with dual collection channels using a coordination contract approach. Moreover, this study explores the effect of collection competition between two collection channels (collector channel and remanufacturer channel) on the acquisition prices offered to consumers as incentive schemes for returning the used items. This study determines the equilibrium solutions for selling prices of remanufactured products, acquisition prices, and transfer price under decentralization, centralization, and coordination settings. Additionally, this study incorporates the impact of collection disruptions into the remanufacturer’s and collector’s problem considering four scenarios. Furthermore, this study proposes a disruption-based two-part tariff contract to accomplish channel coordination in the RSC system with dual-collection channel under collection disruptions. Our finding reveals that the suggested coordinated scheme efficiently coordinates the disrupted RSC with dual collection channels even when under high possibility of collection disruptions. Moreover, our coordination plan is of environmental and economic benefits, as it can boost the return quantities and can increase RSC participators’ profits.
