Some Transmuted Software Reliability Models

Some Flexible Software Reliability Growth Models using Two-Dimensional Approach

The concern for software reliability has grown over a period of time especially with the advent of real life systems such as satellite and shuttle control, telephone, internet and banking services. In today’s life the computers are being used to monitor and control safety critical and civilian systems with a great demand for high-quality software products. So reliability is a primary concern fo...

Recalibrating Software Reliability Models

In spite of much research effort, there is no universally applicable software reliability growth model which can be trusted to give accurate predictions of reliability in all circumstances. Worse, we are not even in a position to be able to decide a priori which of the many models is most suitable in a particular context. Our own recent work has tried to resolve this problem by developing techn...

Predictability of Software-Reliability Models

Conclusions Though several softwarereliability growth modek have been proposed to estimate the reliability growth of a software project, few guidelines exist about which model should be used. We present a 2-component predictability measure that characterizes the long-term predictive capability of a model. Component 1, average error, measures how well a model predicts throughout the testing phas...

Software Reliability Modelling: Some Achievements and Limitations

Stochastic Justification of Some Simple Reliability Models∗

In this paper we derive conditions on the internal wear process under which the resulting time-to-failure model will be of the simple collapsible form (Oakes, 1995, Duchesne and Lawless, 2000) when the usage accumulation history is available. We suppose that failure occurs when internal wear crosses a certain threshold and/or a traumatic event causes the item to fail (Cox, 1999 and Bagdonavičiu...
