中文摘要
軟體可靠度在開發軟體過程中扮演著很重要的角色。在過去三十年，已經有許多的學者提出各種可靠度的模型，應用於檢測軟體產品的可靠度，尤其在交通運輸、電腦及醫學上都已經廣泛的使用。本文我們利用離散型可靠度模型、成本模型及損失函數來探討軟體的最佳發行時間，我們並介紹有效控制其開發成本。

Abstract
Software reliability plays an important role during the development of a software. In the past three decades, many scholars have made many different model used to detect reliability of software products. Especially, the method is widely used in the transportation, computers and medical science. In the paper, we discuss a discrete reliability, specific cost model and loss function to explore the optimal release time. We introduce an effective control costs for the development of software.
