Software Reliability Modeling
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...
متن کاملOptimal allocation of test resources for software reliability growth modeling in software development
Component-based software development approach has become a trend in integrating modern software systems. To ensure the overall reliability of an integrated software system, its software components have to meet certain reliability requirements, subject to some testing schedule and resource constraints. Efficiency improvement of the system-testing can be formulated as a combinatorial optimization...
متن کاملArchitecture-based software reliability modeling
In this paper, we present an architecture-based approach for modeling software reliability. Our approach aims at modeling reliability on various software infrastructures and in any stage of software life cycles. To this end, we utilize characteristics of architectural styles to capture non-uniform behaviors of software embodying heterogeneous architecture. Furthermore, a state model that synthe...
متن کاملModeling and Analysis of Software System Reliability
Software is an integral part of many products, ranging from durable goods such as household appliances to large and complex commercial and industrial systems. With the increasing dependency on software in our daily lives, the size and complexity of software systems has grown dramatically. This trend is of great interest to the software industry, calling for more practical analysis and predictio...
متن کاملSoftware Reliability Modeling and Exponential Order Statistics
Properties of software failure times modelled as realizations of order statistics generated by independent but non-identically distributed exponential random variables are developed. Edgeworth and saddle point approximations to central order statistic densities so generated are developed using an exact integral representation of these densities. A comparison of Edgeworth and saddle point approx...
