在进行软件开发时,该如何回答这样的问题,"当前开发的软件可靠性是什么?"这个对于用户来说是非常重要的信息,却难以表述。以此为方向,研究了一种面向开发过程的软件可靠性预测方法,结合软件开发各个阶段的特点,通过合理地采用软件可靠性早期预测模型,实现对开发中软件可靠性的预测。实践应用表明,该方法紧密结合软件开发的实际,反映了软件可靠性与开发人员的水平、开发规范的标准之间的联系,有助于采取必要的措施提高其以后的可靠性,从而也验证了该方法的工程实用性。
During software development,how to answer the question like "what is reliability about the software which is developing right now" is crucial for users whereas difficult to express.Based on this direction explored a reliability prediction method for the process of the software development,and through reasonable use of the software reliability prediction model,combining with the characteristics of every stages of software development,achieved the prediction of software reliability during the development.The practical application shows that the method closely connects with the actual software development,reflects the links between the software reliability,the level of developers and standards of norm during development,and it is helpful to take the necessary measures to improve the reliability in its future,which also proves the engineering practicability of the method.
