Abstract With the development of the society, science and technology, the procession of economic globalization is changing dramatically, market demand is also showing a more variety of features. Faced with the complex and volatile external environment, the cooperation on space and time in supply chain is becoming more di?cult. So, how to establish a reasonable mechanism to coordinate the supply chain between the members, how to improve bene?t of supply chain, how to achieve sharing revenue and risk and so on, all is becoming an important research issue in ?eld of supply chain management. As a way to achieve these goals and a e?ectual solution, supply chain contract has been drawing much attention from the academia and business more and more. In this thesis, ?rstly, thesis describes some related concepts of supply chain coor- dination, by analysis on domestic and international supply chain contract research and research status, we study the revenue sharing contract for coordinating multi-echelon linear supply chain model and for retailers’optimal order policy with manufacturers reliability. Secondly, the pro?t model of supply chain is established under random demand and random yield. We discuss existence of assembler’s maximal expectation pro?t and analyze the e?ect of various contracts to assembler’s pro?t. According to buyback contract and revenu
