This paper investigates the coordination of deliveries between a vendor (or manufacturer) and multiple heterogeneous buyers (or retailers) in a two-level supply chain with a decentralized decision process. A continuous deterministic model is presented. To satisfy the buyers’ demands, the vendor delivers the product in JIT shipments to each buyer. The buyers’ demands (continuous) have to be satisfied by the vendor. The production rate is constant and sufficient to meet the buyers’ demands. The product is delivered in discrete batches from the vendor’s stock to the buyers’ stocks and all shipments are realized instantaneously. A special class of production-delivery-replenishment policies of the vendor and the buyers are analyzed. In a competitive situation, the objective is to determine schedules, which minimize the individual average total cost of production, shipment and stockholding in the production-distribution cycle (PDC).
