在日常生活中，電子設備已經脫離不了我們的生活，而在開發一個軟體的過程中，軟體可靠度在其中扮演相當重要的角色。本文中我們採用smith(1997)所提出的冪穩定模式(power steady model)作為連結各「測試-除錯」階段的方法，並建構批次模式以及其成本模型，再利用成本模型得出一個判別是否結束測試並將軟體發行的策略。

In daily life, electronic devices have been inseparable from our lives, but in the process of developing a software, software reliability plays a very important role. In this paper we use the power steady model proposed by Smith (1997) as a method to link each stage of "testing-debug", and to construct batch model and cost model. Therefore, the cost model can be used to arrive at a judgment whether to end the software testing and to release the software .
