Software Reliability Model is categorized into two, one is static model and the other one is dynamic model. Dynamic models observe the temporary behavior of debugging process during testing phase. In Static Models, modeling and analysis of program logic is done on the same code. A Model which describes about error detection in software Reliability is called Software Reliability Growth Model.

{ With the growing emphasis on reuse, software development process moves toward component-based software design. In this paper we present an overview of the architecture-based approach to reliability estimation of the software composed of components. First, the common requirements of the architecture-based models are identiied, and the classiication is proposed. Then, the key models in each cla...

Software problems are the main causes of system failures today. There are many well-known cases of the tragic consequences of software failures. In critical systems, very high reliability is naturally expected. Software packages used everyday also need to be highly reliable, because the enormous investment of the software developer is at stake. Studies have shown that reliability is regarded as...

Software-reliability engineering (SRE) stems from the needs of software users. The day-to-day operation of our society is increasingly more dependent on software-based systems and tolerance to failures of such systems is decreasing. Software engineering is not only expected to help deliver a software product of required functionality on time and within cost, it is also expected to help satisfy ...

1 Introduction This chapter proposes an overview of some aspects of Software Reliability (SR) engineering. Most systems are now driven by software. So that, it is well-recognized that assessing reliability of software applications is a major issue in reliability engineering, particularly in terms of cost. But predicting software reliability is not easy. Perhaps the major difficulty is that we a...

Software reliability models are used to describe the evolution of the software debugging process and to measure the quality of the software. In software testing, we execute the software with a test suite that resembles the anticipated usage proole. We observe failures (unacceptable performance) caused by bugs (faults) in the program. The bugs are largely due to errors in requirement speciicatio...

The primary purpose of this brief nontechnical overview of software reliability engineering (SRE) is to clear up some misconceptions regarding SRE. We discuss several uses of SRE, and emphasize the importance of operational pro les in SRE. An SRE process is outlined in which several SRE models are applied simultaneously to failure data, and several versions of key components may be used to impr...

oftware Reliability Growth Model is a mathematical model of how the software reliability improves as faults are detected and repaired. The performance of SRGM is judged by its ability to fit the software failure data. How good does a mathematical model fit to the data and reliability of software is presented in the current paper. The model under consideration is the, Gompertz model. MLE method ...
