Research On The Revenue Sharing Contract With Overconfidence Decision-Making Body Of Supply Chain

Supply chain contract coordination is an effective way to coordination supply chain.After considering the overconfidence of decision makers,the supply chain coordination research has more realistic significance.In order to study the change of the revenue sharing contract and whether it can continue to coordinate the supply chain.The supply chain for the following three cases were studied: supply chain with overconfidence retailer;supply chain with over confidence supplier;supply chain with overconfidence supplier and retailer.First,set up a revenue sharing contract model,get the coordination range,if there is room for improvement in the coordination of contract,then aim at the existing problem to improve.Expatiates research is carried out from three aspects.To the two level supply chain with overconfidence retailers,established a revenue sharing contract model,the arithmetic analysis shows that the revenue sharing contract can only coordinate the retailer's overconfidence range in 0~0.16.Through the arithmetic analysis of the data found that the fundamental reason for the overconfidence degree coordination range small is the retailer to order quantity too much.Aiming at the fundamental reason,introducing repurchase strategy,establish repurchase strategy under the revenue sharing contract model,through the arithmetic analysis of model,found that repurchase strategy under the revenue sharing contract to the retailer's overconfidence coordination range up to 0~0.71.and within the coordination range,the supply chain can achieve perfect coordination.To the two level supply chain with overconfidence supplier,established a revenue sharing contract model,the arithmetic analysis shows that the contract can coordinate the supplier's overconfidence range in 0~1,which can coordinate with suppliers for any degree of overconfidence in supply chain.But can't achieve perfect coordination.To the supplier and the retailer both overconfidence in two-stage supply chain,set up the revenue sharing contract model,by arithmetic analysis could found that the revenue sharing contract can coordination the supply chain with the supplier and the retailer' overconfidence range 0~0.20,and the range is small because of the retailer's overconfidence made it ordering too much.In this regard,introduced the repurchase strategy to revenue sharing contract,establish a revenue sharing contract model under the repurchase strategy,by arithmetic found that the overconfidence coordination range has greatly improved to 0~0.99.But in the coordination of the range,the supply chain can not achieve perfect coordination.
