Perishable Goods Supply Chain Coordination Strategy Based On The Credit Payment

The competition in 21st is between supply chain and supply chain. The style of competition which each enterprise does things in his own way doesn't adapt to new market environment any more. Only each enterprise in supply chain coordination, can the supply chain had an optimal effect; Credit payment is an important channel to financing, though sellers may pay some opportunity cost, they can encourage buyers increasing their order quantity and understand buyers' credit condition better.

The research results don't have important economic significance in the inventory optimization and effectively allocation of the capital only, it also has the practical significance in the saving of the limited social energy.Take above into consider, this paper based on current situation that sellers use policy of credit payment to promote buyers'order quantity, add in some more realistic factors, research the strategy of Inventory optimization based on credit payment in supply chain furthermore. The research contents of the paper can be concluded as follows:1) The paper generalizes the related works at home or abroad from two different perspectives:supply chain coordinate and credit payment. Then, it analyses and compares the research at home or abroad, summarizes the current limitations of research, and points out some feasible research directions.2) The paper elaborate the related theory of supply chain coordination, analyses the deficiency and improvement and summarizes various deficiency of credit payment and it's risks in today's business environments.3) Taking deteriorating items, inflation, demand rate as a function of retailer price, inventory of manufacturer and so on into account, the paper use quantitative analysis, investigates coordinate model from three different perspectives:single manufacturer--single retailer,single manufacturer--multi-retailers and two-level credit payment. Then it proposes optimization algorithm and prove its conclusion.
