本論文主要探討零售商販賣季節性商品(seasonal goods)時，考慮存貨水準與需求相依下，最適動態定價策略議題。零售商所面對的環境是在有限的銷售期間內將固定的存貨售出，一旦銷售期間結束商品的剩餘價值為零。在現實生活中，季節性商品的易腐性(perishability)與市場快速變化，隨著銷售時間的消逝，對消費者而言不再具有初始的價值，消費者的購買意願隨時間遞減。然而消費者的購買意願不僅受時間遞減影響，亦受剩餘存貨數量、樣式多寡所影響。故在研究中，以週期性定價策略(Periodic Pricing Review Policies)模式為基礎下，提出存貨水準與需求相依因素，利用週期性定價模式與本研究最適定價模式取得之價格與收益數據，分析兩者的差異，追求更合理、更準確的定價決策過程。

In this paper we study optimal dynamic pricing strategies for the seasonal goods with consider of inventory-level dependent demand in retail stores. The main assumptions that determine the pricing policy in our paper are the finite planning horizon, the perishable of the products, and the fact that, after deciding the initial inventory, the cost of the goods is a sunk cost. On the other hand, the salvage value of the unsold units is zero after the selling horizon. Practically, in the fashion industry that it’s perishable and its market vary fast, in general, consumers willing to pay lower price to buy toward the end of the season. But it is influenced that consumers’ purchase will is not merely decreased progressively by time, also influenced by the quantity of the surplus stock, number of design. We use the periodic pricing review policies as a benchmark against which we compare more rational and more accurate models that consider inventory-level dependent demand factor. We also show the difference that the initial pricing and the expecting profit of the models which we present.
