摘要
软件可靠性模型是根据与软件可靠性相关的数据,以统计方法或模糊方法对软件的可靠性进行度量、评估和预测。以往对软件可靠性的预测是针对原始数据进行建模,而原始数据所存在的不平稳性的缺陷,直接导致可靠性模型预测结果的误差较大。本文以软件可靠性模型研究中原始数据存在的问题为出发点,探讨提高软件可靠性预测的方法。通过对可靠性数据的预处理,解决其不平稳性导致预测结果误差较大的问题。
Software reliability and software reliability model is to measure, assess and predict the reliability of software in statistical or fuzzy method basing on the data. In the past prediction of software reliability is based on the raw data, while the raw data is usually unstable, which leads directly to the results of the reliability model has a greater error. This paper, begins with the problems of software reliability, explores the ways to improve software reliability prediction, software reliability, and solves the problem of data fluctuated by data pre-processing.
