CAPACITY COORDINATION MECHANISM FOR SUPPLY CHAIN UNDER SUPPLY-DEMAND UNCERTAINTY

In consideration of the supply-demand uncertainty, this paper mainly discussed the capacity coordination of product service supply chain. Facing supply uncertainty, it built a subcontractor-supplier coordination model based on penalty contracts. It was found that if the subcontractor takes punitive measures, the benefits caused by the increased subcontract demand can offset the supplier's shortage loss. As to the demand uncertainty, we constructed a coordination model consisting of subcontractors and integrated service suppliers based on the benefit sharing contract. The results found that the integrated service suppliers' order quantity and the expected joined revenue of subcontractors and integrated service suppliers will increase. Besides, considering suppliers' shared capability information, we built a product service supply chain coordination model based on penalty-benefit sharing joined contracts. The results showed that the joined contracts can decrease the uncertainty of capacity supply and soften the impact of demand uncertainty, thus raising the whole benefits of the product service supply chain, and ensuring the benefit increase of all related enterprises.
