Abstract: The revenue-sharing contract in supply chain contract coordination is studied in this paper.The random expected value model of revenue-sharing contract coordination in supply chain with underage cost is developed and the relation between revenue-sharing contract parameters for coordinating decentralized supply chain is educed,and the effect of revenue-sharing mechanism for improving the operational performance of entire supply chain is analyzed.A mixed intelligent arithmetic for random expected value model is designed and simulation is done aiming at revenue-sharing contract coordination model,and the impacts of variety of revenue-sharing contract parameters on supply chain members' performance are discussed.The results show the random expected value model of revenue-sharing contract coordination developed in this paper is practical and coordinates the operation of supply chain with random demand.

Key words: supply chain, revenue sharing, contract, random expected value model, mixed intelligent arithmetic
