Research On Supply Chain Ordering、Pricing And Coordination Mechanism Under Delay In Payment

In supply chain there are three different and relative flows, namely, fund flow、information flows and material flows. But as one of the most important elements, theimpact of fund flow on supply chain is not main focus in published literature. In fact, asone of required resources of survival and development for enterprises, it is safe to saythat the lack of fund will be normality for enterprises, specially mediate or smallenterprises.This dissertation argues the issues of one basic model and there extended modelsbased on the newsboy model under delay in payment and the uncertain market demand,which focus on ordering and pricing optimal strategy of supply chain. The mainresearch issues and innovative results as follows:（1）Establishing a basic model, argues the issues such as ordering and pricingoptimal strategy on supply chain and co-ordination. It shows that NASH equilibriumexisted in decentralized decision, and even though a retailer can be more positive inorder quantity, but order quantity is lower than that of centralized decision. At sametime, it can ease off the financial tension of the retailer. By introduced buy-back contractcan maintain coordination of supply chain.（2）The operation and coordination of supply chain under delay in payment witha loss-averse retailer. Indicates that nash equilibrium existed in decentralized decision,in which the loss-averse retailer is likely aggressive in ordering: the order quantity isdecreasing with respect to the retailer’s increasing loss-aversion; the wholesale price isincreasing with respect to the retailer’s increasing loss-aversion; the supplier is apt tochoose the retailer with less loss-aversion in order to improve performance; Buy-backcontract that can be proved flexible maintain coordination of supply chain under thissetting.（3）It is argued that the supplier’s problem about the balance of profit maximumand the risk that the retailer can not pay back at term under the uncertain demand facedby retailer and delay in payment on supply chain. Discussed supplier’s pricing policiesaccording to setting accounts receivable ratio and finds that under setting supplier’s cost and ratio of accounts receivable, under setting retailer’s budget and supplier’s cost, thegoal of accounts receivable should be adjusted. And studied how to reach supply chaincoordination. It integrates financing policy and operation policy in supply chainmanagement and proposes a novelty method to optimize decisions(including reachingsupply chain coordination) according to account receivable ratio, that is, through settingproper the goal of account receivable ratio can achieve risk control and coordination atsame time without traditional contracts.（4）Based on the change of control power structure on supply chain, research on,when retailer get credit from the supplier, the optimal decision of the members of supplychain under the fact that dominant power transferring from upstream to downstreambecomes the trend gradually. The results show that simplicial credit can not make surecoordination, but through the financing contract, retailer can make the deal withmanufacturer with higher credit-aversion that maintains supply chain coordinated andkeeps the same utility level to retailer.
