Study On Ordering Policy For Daily Perishable Product In Supply Chain

The customers demand now has such characteristics as more varieties and little batch. It needs the enterprise to meliorate in ordering policy so as to respond to the market fleetly. Aim at promoting long cooperation and correspondence of the supplier and distributor, Operational research and fuzzy mathematics is applied to research the optimal ordering policy for distributors based on progressive price discount, short life cycle, coordinated replenishment in the two-stage perishable supply chain.First, the reformation and development of ordering function in the supply chain is analyzed, and then the characteristics and common policies of ordering perishable product are summarized.Second, aim at a kind of deteriorating items with shelf life, the paper divide the retailers into the risk-lovers and risk-averters, the supplier can choose providing quantity discount or not. The paper researches the correspondence for distributor for two ordering opportunities. When the supplier provides the discounts for the ordering quantity, the profit-making level of retailer is higher than that without the discounts.The third, aim at a kind of new-style commodities on the market, fuzzy variable is used to describe the indeterminacy of demand information. Comparing to existing commodities, the new-style commodity is one-way substitutable. An expected profit model of the distributor is set up based on the newsboy model, and the fuzzy variable is transformed into a generalized random variable by generalized density function, so the computation changes simple. At last, a number case is presented.The fourth, provided that the retailer cannot reach the discount borderline provided form the supplier when he orders independently, the paper solves the problem that several retailers organize to order perishable product from one supplier. Members come to an agreement: the member with surplus inventory can transship some surplus to the member with OOS during the period of sailing. Aim at the characteristics of perishable product, a different constraint term on transshipment price is proposed and the expected systemic profit model is set up too.Last, when the demand is stochastic, the distributor sells the product with the policy of progressive price discount. The bended price-demand curve for distributors is used to substitute for linear demand curve, and a new expected profit model is set up. Then we develop an algorithm for calculating the times of the price discounts. The study...
