Study On Linear Rebate Cooperation Model And Postponement Strategy Of Perishable Goods Supply Chain

Long lead-times, short sales period, low salvage value and volatile markets etc characterize perishable goods. As the life of the product is shorten and the speed of updating is increased, more and more products have the character of the perishable goods. So people pay more attention to the management of perishable goods supply chain. But the biggest challenge that the supply chain faces is the supply chain coordination is difficult to obtain. The supply chain contract is the effective supply chain coordination mechanism, more and more researchers and enterprisers attach importance to the study of supply chain contract. This paper discusses some problems about the supply chain contracts of perishable goods.At first, the paper sums up the learned productions of eight supply chain contracts of perishable goods at home and abroad, such as Wholesale Price-only Contract,Return Contract,Revenue-sharing Contract,Flexibility-quantity Contract,Quantity-discount Contract,postponement contract,Sales-rebate Contract,Profit-sharing Contract. Then it concludes the main views and methods to study the supply chain contracts of perishable products and has a comparison of those contracts.The second, the profit of decentralized control and centralized control to the supply chain of Perishable goods in the condition which there is only one manufacturer and one retailer is discussed. A model of supply chain cooperation is set up based on the linear rebate policy. The optimal product quantity which can maximize the whole supply chain profit is accepted by the retailer when the linear rebate is in a effective scale. It is also demonstrated that the win-win and the Pareto improve can be attained in the supply chain by employing the incentive linear rebate. At last, a numerical example of the rebate's effective scale and the detail expression are given.Thirdly, paper develops economic-order-quantity model (EOQ)-based models with perishable items to evaluate the impact of a form postponement strategy on the retailer in a supply chain. We formulate models for a postponement system and an independent system to minimize the total average cost function per unit time for ordering and keeping n perishable end products and compare them. Our theoretical analysis shows that a postponement strategy for perishable items can give a lower total average cost when deterioration rate is small. At the end, we get the conclusion that the gap of the total average cost between two systems becomes larger when deterioration rate becomes larger.Finally, the achievements and the limitation of this paper were summed up, and the further research directions were pointed out.
