在本研究中我們先建構一個系統化的模式去尋找在調整生產率下之整合存貨模式的最佳策略。這個模式是基於考慮總成本最佳化下之一般存貨策略。然而在大部份相關文獻中均假設調整生產率已知，並不實際。本論文中假設模糊調整生產率，運用解模糊重心法，去尋找估計模糊語意下的一般總成本，而後得到相應最佳買方的購買數量和每一個品項從賣方運送到買方的整數批次。最後以一個範例說明模糊模式與明確模式比較的結果。

In this paper we present a stylized model to find the optimal strategy for the integrated inventory model with fuzzy adjustable production rate. This model with such consideration is based on the total cost optimization under a common stock strategy. However, the supposition
of known adjustable production rate in most related publications may not be realistic. This paper proposes the triangular fuzzy number of adjustable production rate and then defuzzify by the centroid method, to find the estimation of the common total cost in the fuzzy sense, and derives the corresponding optimal buyer’s quantity consequently and the integer number of lots in which the items are delivered from the vendor to the purchaser. A numerical example is provided and the results of fuzzy and crisp models are compared.
