将未确知理论应用于软件可靠性建模研究,采用其分析软件故障过程,用未确知数学描述软件失效特征计算软件可靠性参数,并在此基础上构建了一个基于未确知数学理论的软件可靠性模型.新模型改变了传统的建模思路,跳出了传统软件可靠性建模过程中关于失效强度变化的各种统计分布假设的束缚,具有较好的适用性,改善了模型应用中的不一致性问题.

In this paper, unascertained mathematical theory is applied to the study of software reliability modeling. It is used to study software fault process, describe software failure character and get software reliability parameters. Finally, a software reliability model based on unascertained theory is proposed in this paper. The new model changes the traditional modeling thought, and brakes away from the statistical distribution assumption about the variety of failure rate in the traditional software reliability modeling process. It has better applicability, which improves the incongruence of model application to some extent.
