Abstract: This paper analyzes uncertainty of software reliability qualitative evaluation. Combining unascertained mathematical theory, software reliability evaluation system is established. Reliability score, unascertained qualitative method, and confidence level rule are proposed. Software reliability qualitative evaluation technology based on unascertained measurement is constructed. The method is applied to qualitative reliability evaluation in interial navigation system, experimental results show the model is practicable and effective.

Key words: software reliability qualitative evaluation, unascertained measure, uncertainty

摘要： 分析了软件可靠性定性评价中的不确定性，结合未确知数学理论，建立了软件可靠性评价指标体系，提出可靠性评分、不确定性量化方法和置信度准则，构造软件可靠性定性评价未确知测度模型，将该方法应用在惯性导航软件系统的可靠性定性评价中，验证了该模型的可用性和有效性。
