Lognormal Process Software Reliability Modeling with Testing-Effort
نویسندگان
چکیده
We propose a software reliability growth model with testing-effort based on a continuous-state space stochastic process, such as a lognormal process, and conduct its goodness-of-fit evaluation. We also discuss a parameter estimation method of our model. Then, we derive several software reliability assessment measures by the probability distribution of its solution process, and compare our model with existing continuous-state space software reliability growth models in terms of the mean square error and the Akaike’s information criterion by using actual fault count data.

Software reliability modeling and cost estimation incorporating testing-effort and efficiency
Many studies have been performed on the subject of software reliability, but few explicitly consider the impact of software testing on the reliability process. This paper presents two important issues on software reliability modeling and software reliability economics: testing effort and efficiency. First, we will discuss on how to extend the logistic testing-effort function into a general form...
متن کاملIncorporating Burr Type XII Testing-efforts into Software Reliability Growth Modeling and Actual Data Analysis with Applications
Software reliability is the probability that the given software functions correctly under a given environment, during the specified period of time. During the software-testing phase, software reliability is highly related to the amount of development resources spent on detecting and correcting latent software errors, i.e. the amount of testing effort expenditures. This paper develops software r...

Software reliability growth model is one of the fundamental techniques to assess software reliability quantitatively. A number of testing-effort functions for modeling software reliability based on the nonhomogeneous Poisson process (NHPP) have been proposed in the past decades. Although these models are quite helpful for the software testing, we still need to put more testing-effort into softw...
متن کاملChange-Point Modeling for Software Reliability Measurement Depending on Two-Dimensional Software Reliability Growth Factors
It is known that the trend of the software reliability growth process changes during testing or operation phases in an actual environment due to a change of specification, software upgrading, a change of fault-target, and so forth. This paper discusses an extended two-dimensional software reliability growth modeling, in which the software reliability growth process is assumed to depend on the s...
