Abstract: In recent years, the supply chain of cold chain has become increasingly frequent and the fresh product occupies an important proportion. Fresh product is a special kind of perishable commodity, which has a random life cycle and can be influenced by sales. So, retailers tend to make price adjustments based on the freshness of the product. The time of changing price is particularly important. In the case of no effect on normal consumption, the retail will take the price strategy to ensure sufficient profit.
The ordering and pricing decision problem with a class of perishable fresh goods for the retailer is studied in one cycle, and the concept of price change point is introduced. The deterioration rate is represented by the three-parameter Weibull distribution, and the demand rate is the function of deterioration rate and the price together. The function of profit maximization is established. Solving the price function can be converted to a controllable Bolza problem which will get the optimal price representation. Through the example, the effect of price sensitivity and price turning point on the profit is studied. Further the sensitivity analysis and the price elasticity are analyzed. It shows that with the time elapsed, the sale price of fresh goods is more and more low; the more sensitive of the customers on price, the backer of the price turning point meanwhilethe price adjustment in the entire sales phase of the 1/2 to the 3/5 near to help increase profits.

Key words: fresh perishable goods, price turning point, survival/hazard characteristics
