We consider a two-echelon supply chain system with one distributor, and one manufacturer, which supply the customers with a kind of short life cycle product. It establishes delivery time and quantity decision models separately in decentralized decision mode and centralized decision mode when the manufacture's delivery time are random, and it also analyses the optimal decisions under these two modes. Case and numerical analyses show that coordination between manufacturer and distributor can not only increase the whole supply chain systems profit, but also increase the product's supply in the market
