成组缺陷纠正的通用指数类软件可靠性模型

Class of General Exponential Software Reliability Model with Group Defect Correction

指数类软件可靠性模型是应用广泛的一类软件可靠性预测模型,其基本假设之一是缺陷一经发现立即纠正。该假设过于苛刻,与实际情况不符,影响了模型的应用和预测准确性。针对通用指数类软件可靠性模型,提出了成组缺陷纠正的指数类软件可靠性模型。同时以指数类模型中的J-M模型为例,利用实际工程数据对成组缺陷纠正的J-M模型进行了验证。

The class of general exponential software reliability model is a group extensive reliability estimate model. One of the basic assumptions is that defect must be corrected immediately when it is discovered. This rigid assumption limits the models＇ prediction precision and their application. Based on this class model, the software reliability prediction model involving group defect correction was proposed. Regarding J-M model as the example, illustrations of the proposed model by using real data were provided.
