Software reliability in the software development process is an important issue. Software process improvement helps in finishing with reliable software product. In this field, SPC (Statistical process control) is a method of process management through application of statistical analysis, which involves and includes the defining, measuring, controlling, and improving of the processes. In measurin...

Communication networks create lot of interest due to their ready applicability in performance evaluation of several communication systems. In communication systems it is customary to consider that the arrivals are characterized by Poisson process. This assumption holds good if the arrivals are homogeneous and independent of time. But in many tele and satellite communication systems the arrivals...

In software development life cycle, software testing is one of the most important tasks; and in the testing, software reliably is very important aspect for any category of software systems. A number of testing-effort functions for software reliability growth model based on non-homogeneous Poisson process (NHPP) have been proposed in the past. Although these models are quite helpful for software...

In this study, software products developed in the course of testing, software managers in the process of testing software test and test tools for effective learning effects perspective have been studied using the NHPP software reliability models. The finite failure non-homogeneous Poisson process models presented and want to use half-logistic distribution as the lifetime distribution which used...

The study aims to provide a Bayesian statistical method with natural conjugate for facilities’ preventive maintenance scheduling related the hybrid competing failure mode. An effective strategy not only can improve system’s health condition but also increase efficiency, and therefore firm needs make an appropriate increasing utilization of system reasonable costs. In last decades, issues deteri...

Software reliability growth models using NonHomogeneous Poisson Process (NHPP) with mean value function – dependent on fault detection rate 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. In the present paper, we have proposed the perfor...

Tandem Queues are widely used in mathematical modeling of random processes describing the operation of Manufacturing systems , supply chains, Computer and telecommunication networks. In many of the communication systems the arrivals are time dependent and can be characterized by a non homogeneous Poisson process. In this paper we developed and analyzed three nodes connected in tandem Queue with...

Software reliability may be used as a measure of the Software system‟s success in providing its function properly. Software process improvement helps in finishing with reliable software product. Software process improvement includes monitoring software development practices and actively seeking ways to increase value, reduce errors, increase productivity, and enhance the developer‟s environment...

Statistical process control is a method of monitoring product in its development process using statistical techniques with the presumption that the products produced under identical process condition shall not always be alike with respect to some quality characteristic(s). However, if the observed variations are with in the tolerable limits statistical process control (SPC) methods would pass t...

In software development process, testing is one of the most important aspects and hence, software reliably is very important factor of software systems. In the last four decades many software reliability growth model based on non-homogeneous Poisson process (NHPP) have been developed which incorporates testing effort function. However, the previous models are quite helpful for software engineer...
