Ontology Web Language for Services (OWL-S), one of the most significant semantic Web service ontologies proposed to date, provides a core ontological framework and guidelines for describing the properties and capabilities of services in an unambiguous computer-interpretable form. Analysis of the quality of service of composite service processes specified in OWL-S enables service users to decide whether...
The aim of vehicular reliability experiment is assessing its reliability, measuring its reliability index and serving for vehicular design, manufacturing and development. In this paper, we present product virtual reliability analysis method, which is based on Virtual Reality and Virtual Prototype technology. It is a software platform that integrates various engineering software and simulated algorithms,...
A probabilistic analytical framework for decentralized load balancing (LB) strategies for heterogeneous distributed-computing systems (DCSs) is presented with the overall goal of maximizing the service reliability in the presence of random failures. The service reliability of a DCS is defined as the probability of successfully serving a specified workload before all the computing nodes fail permanently...
Web service composition is a distributed model to construct new web service on top of existing primitive or other composite web services. However, current service technologies, including proposed composition languages, do not address the reliability of web service composition. Thus it is hard to predict the system reliability. In this paper, we propose a method to compute system reliability based...

Future network systems and embedded infrastructure devices in ubiquitous environments will need to consume low power and process large amounts of network packet traffic. In order to meet necessary high processing efficiency requirements, future processors will have many heterogeneous cores with reduced reliability due to low voltage, small transistor sizes, semiconductor wearout, and environmental...
Non-homogeneous gamma process (NHGP) models with typical reliability growth patterns are developed for software reliability assessment in order to overcome a weak point of the usual non-homogeneous Poisson process (NHPP) models. Though the analytical treatment of NHGPs as stochastic point processes is not so easy in general, they have an advantage to involve the NHPPs as well as a gamma renewal process...
In this paper, two problems of optimal resource allocation to modules during testing phase are studied: (1) maximization of the number of faults removed when the amount of testing-effort is fixed, and (2) maximization of the number of faults removed satisfying a certain percentage of initial faults to be removed with a fixed amount of testing-effort. These optimization problems are formulated as nonlinear...
In a competitive business landscape, large organizations such as insurance companies and banks are under high pressure to innovate, improvise and distinguish their products and services while continuing to reduce the time-to market for new product introductions. Generating a single view of the customer is vital from different perspectives of the systems developer over a period of time because of the...
Software reliability is the most important measure of software quality and, naturally, should be customer- oriented. In the current article, a reliability study related to the software exploitation behavior for the remote control of the GVR (gas vacuum recloser) reclosers, using the homogeneous Poisson method, is going to be examined.
This paper presents a methodology for modeling, analyzing, and selecting substations for industrial customers based on different criteria, such as initial investment, interest rate, life cycle, reliability, costs of interruption, maintainability or a combination of these criteria expressed as life cycle cost (present value). The methodology is implemented by utilizing specialized tools for calculating...
