This paper develops a joint copula reliability model for systems subjected to dependent competing risks caused by two degradation processes and random shocks. The two degradation processes follow gamma processes and the random shocks follow a non-homogeneous Poisson process (NHPP). Their interdependence relationship is modeled by a copula function, which is determined by a two-stage method base...

software quality attribute and Software reliability estimation is a hard problem to solve accurately. However for management of software quality and standard practice of the organization, accurate reliability estimation is important. Non-homogeneous Poisson Process (NHPP) models and Artificial Neural Network (ANN) models are among the most important software reliability growth models. In this p...

A tool remaining useful life prediction method based on a non-homogeneous Poisson process and Weibull proportional hazard model (WPHM) is proposed, taking into account the grinding repair of machine tools during operation. The intrinsic failure rate built according to data. WPHM established by collecting vibration information operation introducing covariates describe In combination with repair,...

Due to the randomness and time dependence of factors affecting software reliability, most reliability models are treated as stochastic processes, non-homogeneous Poisson process (NHPP) is used one. However, failure behavior does not follow NHPP in a statistically rigorous manner, pure random method might be enough describe behavior. To solve these problems, this paper proposes new integrated ap...

s In this paper, a scheme for constructing software reliability growth model based on NonHomogeneous Poisson Process is proposed. Although various testing-effort functions for software reliability growth model based on non-homogeneous Poisson process (NHPP) have been proposed. These software reliability growth models are quite helpful for software developers and have been widely accepted and ap...

In this paper, Software reliability is the anticipation of operations which are free of error in the software in a stated environment during the detailed time duration. Statistical Process Control can survey the gauging of software failure and thereby devote significantly to the enhancement of software reliability. Such an assessment assists the software development team to pinpoint and diagnos...

Nonhomogeneous Poisson processes (NHPPs) are frequently used in stochastic simulations to model nonstationary point processes. These NHPP models are often constructed by estimating the rate function from one or more observed realizations of the process. Both parametric and nonparametric models have been developed for the NHPP rate function. The current parametric models require prior knowledge ...
