Software Reliability Models-Software reliability models are statistical models which can be used to make predictions about a software system's failure rate, given the failure history of the system. The growth model represents the reliability or failure rate of a system as a function of time or the number of test cases. Software reliability modeling and prediction during product development is an area of reliability that is getting more focus from software developers. In the past few decades, a great number of hardware and software reliability models have been proposed to address hardware failures in hardware subsystems and software failures in software subsystems, respectively. It is described as the ability of a system or component to perform its required functions under static conditions for a specific period. For hardware/software systems, the results of the basic software reliability model can be used to estimate the number and types of equipment that must be supplied when a software maintenance facility is required as a part of the contractual effort. 0000110546 00000 n The ACM Joint European Software Engineering Conference and Symposium on the Foundations of Software Engineering (ESEC/FSE) is an internationally renowned forum for researchers, practitioners, and educators to present and discuss the most recent innovations, trends, experiences, and challenges in the field of software engineering.
