本研究提出在靜態銷售市場下判斷價格、保固長度及生產率之理論模型及實證研究。對於理論部份，我們提出用於判斷產品的價格、保固長度和生產率決策，以獲得最佳利潤的決策模式。實證部份，我們的目的在選擇適合的銷售模型，實證分析結果驗證理論模型的可行性，主要是一般銷售模型，無法得知銷售率函數具體型態，即無法確認一般模型的可行性。銷售模型的資料來源主要採用電池的銷售資料，透過非線性迴歸估計價格、保固長度及生產率之結果。最後，實證研究分析之結果與理論探討之模型爲一致，驗證理論模型的可行性。

The present paper provides a theoretical development and empirical study on determining price, warranty length and production rate in the static sales market, where word of mouth is not important. For the theoretical development, we present the decision model of determining the optimal price, warranty length and production rate of a product such that the present value of the product profit may be maximized. The empirical study aims at choosing among the alternative model specifications and assessing the shapes of the sales rate function. The sales rate functions are estimated by nonlinear regression, and then are tested by using battery sales data as input while price, warranty length and production rate as outputs. Results of the empirical study are consistent with the corresponding theoretical predictions and consequently show the applicability of the decision model.
