Abstract: For the online customization,by considering the randomness of finished and semi-finished goods'passing rate and all types of costs and benefits,the decision of input quantities on supply chain composed with one manufacture and one supplier was researched.Under decentralized and centralized decision-making,the maximum model of expected profits for each enterprise and the whole supply chain were constructed respectively based on game theory.The existence and uniqueness of the optimal solution were discussed based on optimization theory,and the corresponding representations were obtained.On this basis,the integrated contract mechanism of wholesale price discount,revenue sharing and output risks was proposed to achieve supply chain coordination,and the expressions for each contract factor and the profits distribution were given.The conclusions showed that the uniqueness of optimal solutions needed to have certain conditions;the optimal solution of manufacture under decentralized decision was greater than ones under centralized decision,while the supplier was on the contrary;the changes of parameters related to the manufacturer had a great impact on decisions of the supplier,while the changes of ones related to the supplier had little impact on decisions of manufacturer.

Key words: customization, random passing rate of output, input quantity decision, supply chain coordination
