Abstract: Supply chain coordination and scheduling can effectively improve the ability of enterprises to deal with supply chain interruption. A two-stage manufacturing supply chain is chosen as research object, and the coordinated scheduling problem of multi-product type supply chain with delivery time constraints in the context of disruption is studied. After the manufacturer receives a workpiece processing order containing multiple product types, each workpiece shall be first processed by the supplier and then delivered to the manufacturer for processing as finished product. If the supplier adjusts its schedule, it will lead to an increase in the cost of the manufacturer, which requires both parties to negotiate. Based on the revenue-sharing coordination mechanism, a scheduling model is built to minimize the total delay cost of the supplier and the total cost of conflict of the manufacturer. To solve the model, a hybrid adaptive genetic algorithm combing adaptive neighborhood search operators is proposed. The experiments results show that the proposed model and algorithm have a good performance.
