ANALYSIS AND PREDICTION OF DEFECTS USING RELIABILITY GROWTH MODELS

In improvement of a software, software errors are unavoidable. For prediction of the defects in a software, we have to develop software reliability growth models to analyse the products and to predict them. The same growth model cannot be used for all the data. Hence various software reliability growth models are used for which the data is divided into several parts and different growth models are used for each data part. Later they are recombined. By combining all the traditional reliability growth models we get a multistage reliability growth model. At each stage, the finest Software Reliability Growth Model is to be applied. There are several criterions to evaluate the defects. The RSS ratio is used to select the best Reliability Growth Model. The Multi Stage Reliability Growth Model is a combination of many new-fangled models. These model shave to provide the software reliability and could support to solve problems which are hard to resolve by using Traditional software reliability growth models.
