A number of analytical software reliability models have been proposed for estimating the reliability growth of a software product. In this paper we present an Enhanced nonhomogeneous Poisson process (ENHPP) model and show that previously reported Non-Homogeneous Poisson Process (NHPP) based models, with bounded mean value functions, are special cases of the ENHPP model. The ENHPP model differs ...

In this article, two different systems subject to shocks occurring based on a non-homogeneous Poisson process (NHPP) are analyzed. Type –I system is consisted of a single unit and type –II system is consisted of two parallel units in which both units operate identically and simultaneously. In type –I system occurrence of a shock causes system stopping and consequently will be received minimal r...

Non-homogeneous Poisson processes (NHPPs) have gained much popularity in actual software testing phases to estimate the software reliability, the number of remaining faults in software and the software release timing. In this paper, we propose a new modeling approach for the NHPP-based software reliability models (SRMs) to describe the stochastic behavior of software fault-detection processes. ...

In this study, non-homogeneous Poisson processes (NHPP) are assumed to analyze annual average temperatures and rain precipitations, considering climate data for some regions of North America reported a long period. A power law process (PLP) is the intensity function (derivative mean value function) or rate \(\lambda\) (t), t \(\ge\) 0 NHPP which events occur (accumulated number years in given t...

We present a hierarchical model of non-homogeneous Poisson processes (NHPP) for information diffusion on online social media, in particular Twitter retweets. The retweets of each original tweet are modelled by a NHPP, for which the intensity function is a product of time-decaying components and another component that depends on the follower count of the original tweet author. The latter allows ...

This paper deals with the reliability prediction of a large and complex software system consisting of a number of modules in which each module has a different failure pattern. A Non-Homogeneous Poisson Process (NHPP) arising from the superposition of power law processes (S-PLPs) is proposed for determining the failure intensity of the software system. A graphical method is illustrated for estim...

Many practitioners currently use rules of thumb to price tasks on online labor markets. Incorrect pricing leads to task starvation or inefficient use of capital. Formal pricing policies can address these challenges. In this paper we argue that a pricing policy can be based on the trade-off between price and desired completion time. We show how this duality can lead to a better pricing policy fo...

Software reliability growth models using Non-Homogeneous Poisson Process(NHPP) with a mean value function –dependent on Linearly falling fault detection rate as proposed in the literature is considered. The well known Sequential Probability Ratio Test (SPRT) procedure of statistical science is adopted for the model in order to decide upon the reliability/ unreliability of developed software. Th...
