| 摘 要： | 软件可靠性与费用的关系是辩证的 :一方面增加可靠性可以减少软件的维修费用 ,避免软件因可靠性低不能使用所造成的开发费用的浪费 ;另一方面增加软件可靠性 ,大都以增加软件开发费用为代价 ,而软件成本的提高又制约了软件的销售和推广。对软件可靠性分配和软件测试终止时间的确定进行了深入分析 ,通过这两条途径实现了软件可靠性和费用的权衡。在此基础上 ,给出了在软件工程中权衡软件可靠性与费用的其它方法。

| Abstract: | The relationship between software reliability and its cost is dialectic. Increasing the software reliability will decrease the maintenance cost and avoid any unnecessary waste. On the other hand, increasing the software reliability will cause an increase of developing cost, which will restrict the marketing and popularization of software. The software reliability assignment technology and the method to establish the optimal time to stop testing are discussed in detail in an effort to balance the software reliability and cost. |
