Abstract

The invention provides a change point based ISQ-FDEFCE software reliability growth model and belongs to the software reliability engineering field. The change point based ISQ-FDEFCE software reliability growth model aims at solving the problems of the existing change point based NHPP type software reliability growth model. According to the change point based ISQ-FDEFCE software reliability growth model, the formula of an ISQ-FDEFCE-CP model which comprises n change points is as follows and accordingly the software reliability growth model is a powerful tool for performing evaluation, analysis and prediction on the software reliability and the guidance is provided for the improvement of the software reliability.

Description

technical field [0001] The invention relates to an ISQ-FDEFCE software reliability growth model based on moving points, and belongs to the field of software reliability engineering. Background technique [0002] Software fault correction rate is a very important parameter in the fault correction process, reflecting the efficiency of fault correction and the working ability of fault correction personnel, and providing a basis for software developers and managers to judge whether to increase or decrease resources. Most software reliability growth models assume that software fault correction rates follow the same distribution. In actual situations, the fault correction rate is affected by factors such as the skill of the fault correction personnel, the difficulty of the fault itself, the fault correction environment and tools. Therefore, the software fault correction rate is neither constant nor smooth, but changes at some points, that is, there are moving points. In order to...
