This paper describes the network modeling techniques that were developed to assess the reliability and availability performance of the Combat Information Transport System (CITS). CITS is the backbone network that provides high-capacity transport of data, voice, and video for all active duty and reserve Air Force bases. The model includes the network topology, the configuration and interconnecti...

Feature is a fundamental design unit in modern solid modeling systems, and this makes a well defined feature interface a matter of concernment in the component-based distributed modeling environment. This paper introduces a feature-based modeling service framework and proposes an interface model of feature-based modeling service toward such a modeling environment, including the support of remot...

Although a large number of degradation models for industrial systems have been proposed by researchers over the past few decades, modeling impacts maintenance actions has mostly limi...

The present paper, titled “optimizing the time of preparation, taking into account the timing of   repair and maintenance using non-linear modeling”, has been implemented with the aim of designing and presenting a mathematical model to get the best sequence of operations leading to minimum the total time of production. The main research question is related to the reduction of time and productio...

Chemical plants face safety hazards and security threats that may induce catastrophic scenarios. Safety barriers are employed widely to protect chemical from accidental intentional undesired events mitigate consequences. Managing effectively economically is a research topic with practical significance. The analysis of event scenarios, including both adverse assessing associated critical regardi...

The global IT industry has now matured. As more and more systems grow old and enter into the maintenance stage, software maintenance (SM) is becoming one of the most carried out and challenging tasks. Besides, the industry is also facing a shift in traditional technical environment by way of use of newer tools and approaches of software development, migration from legacy software to current sof...

Efficient and on-time maintenance plays a crucial role in reducing cost and increasing the market share of an industrial unit. Preventive maintenance is a broad term that encompasses a set of activities aimed at improving the overall reliability and availability of a system before machinery breakdown. The previous studies have addressed the scheduling of preventive maintenance. These studies ha...
