摘要

提升生產效率以降低總成本，這是企業在生產的過程中所欲極力追求的目標。在實務之中，可以常見到，廠商間的信用交易、不良品重工與部分欠撥的狀況是並存的，而且會影響到總成本。本研究主要探討信用交易、不良品重工與部分欠撥下的生產政策。在模型一，我們先考慮信用交易與不良品重工到生產政策之中；爾後，延伸第一個模型，把部分欠撥考慮到第一個模型中，建立模型二。本研究之目的在求取最佳化的生產批量以及最大允許欠撥水準以極小化製造商總成本。藉由納入信用交易、不良品重工與部分欠撥的情況，來延伸傳統經濟生產量模型以更能反映實務狀況。我們發展演算法以求解提出的問題。最後，使用數值案例說明求解過程，並提出結論。

Improving the production efficiency in order to reduce the total cost is an aim that most manufacturers pursue actively. In reality, trade credit, reworking of imperfect quality items and partial backlogging exist side by side and affect the manufacturers’ costs. This paper studies the production policy under trade credit, reworking of imperfect quality items, and partial backlogging. In model 1, we consider trade credit and reworking of imperfect quality items into the production policy; afterward, we extend model 1 to consider partial backlogging and then establish model 2. We determine the optimal production lot size and maximum backorder level to minimize the total cost. This paper extends the traditional EPQ model by considering trade credit, reworking of imperfect quality items, and partial backlogging to cope with more realistic situation. We develop algorithms to solve the problem described. Finally, we use numerical example to explain process of solution and present the conclusion.
