We study a two-echelon supply chain that consists of a manufacturer and a seller who is facing uncertain demand in a selling period with a fixed length. Due to a variety of uncontrollable factors, the delivery time is uncertain. We build a revenue consistency compensation model which describes delivery delay situation. Besides, we compare decentralized decision with centralized decisions through the optimal order quantity and revenues changes. Based on a numerical case example, we focus on assessing advantages and limitations of coordination in response to demand and delivery time uncertainty. Thus, a theoretical support for business decisions is provided.
