During a debugging operation, there is a high probability that an additional fault will be introduced into the programwhen removing an existing fault. Thus, perfect debugging is an ideal but impractical assumption when modeling software reliability. If the debugging of a software system is imperfect, more faults may be introduced and detected. In such cases, it may be necessary to addmore staff...

The fault debugging progress is influenced by various factors all of which may not be deterministic in nature such as the debugging effort, debugging efficiency and debuggers skill, and debugging methods and strategies. In order to address these realistic factors that influencing the debugging process we propose an integrated nonhomogeneous Poisson process (NHPP) based software reliability mode...

In order to overcome the limitations of debugging process, insufficient consideration of imperfect debugging and testing-effort (TE) in software reliability modeling and analysis, a software reliability growth model (SRGM) explicitly incorporating imperfect debugging and TE is developed. From the point of view of incomplete debugging and introduction of new fault, software testing process is de...

Debugging actions durin.g the test/debug phase of software d e ve1op.m e nt are la ot always performed perfectly. That is, not all th.e software faults detected are perfectly removed without introducing new faults. This phenomenon is called the imperfect debugging. The HyperGeo ni et ric Dist 1-i but i on software relia bilat y growth Model (HGDM) was developed for estimating the number of soft...

A new approach called RESID is proposed in this paper for estimating reliability of a software allowing for imperfect debugging. Unlike earlier approaches based on counting number of bugs or modelling inter-failure time gaps, RESID focuses on the probability of “bugginess” of different parts of a program buggy. This perspective allows an easy way to incorporate the structure of the software und...

Software reliability is one of the most important characteristics of software quality. Its measurement and management technologies employed during the software life-cycle are essential for producing and maintaining quality/reliable software systems. Herein, we discuss a modified approach to calculating the delivery cost of a software product, when warranty is to be provided, with an imperfect d...

One of the most important decisions related to the efficient management of testing phase of software development life cycle is to determine when to stop testing and release the software in the market. Most of the testing processes are imperfect once. In this paper first we have discussed an optimal release time problem for an imperfect faultdebugging model due to Kapur et al considering effect ...

In this paper, we construct a software availability model considering the number of restoration actions. We correlate the failure and restoration characteristics of the software system with the cumulative number of corrected faults. Furthermore, we consider an imperfect debugging environment where the detected faults are not always corrected and removed from the system. The time-dependent behav...
