model is established so that client systems will not function without the server, and the server is not available, department members will sit around unable to use the system — just as we did twenty years ago when the mainframe was down. Many of us have memories of those days and no desire to return to them. The risk of server downtime is substantial. A good system administrator is the best pro...

The deregulation in power systems brings some new issues in equipment maintenance scheduling where more coordination and communication among different entities is required. In this paper, the mobile agent software is applied in the facility maintenance scheduling in deregulated power systems environment. In the given example, the problem is de-coupled into a master problem and a sub-problem usi...

A finite-time disturbance-observer (DO)-based fuzzy sliding mode cooperative backstepping (FDFSM-CB) scheme is proposed, to improve the synchronization performance and reduce its error under disturbance between multiple permanent magnet synchronous traction motors in low-speed urban rail transit (URT). First, each motor supposed an agent of multi-agent system (MAS), information can be transmitt...

In this paper, a single-product, single-machine system under Markovian deterioration of machine condition and demand uncertainty is studied.  The objective is to find the optimal intervals for inspection and preventive maintenance activities in a condition-based maintenance planning with discrete monitoring framework. At first, a stochastic dynamic programming model whose state variable is the ...

in today's competitive market, quality has an important role in manufacturing system. the manufacturers attempt to maintain their production system in a proper condition to produce high quality products. one of the key factors to achieve this goal is maintenance policy. most studies on maintenance focused on machines and less attention has been paid to human resources as the most important...

Predicting the maintenance and management costs and replacement age of tractors in agricultural mechanized units, is important from several points. So, doing a timely agricultural operations, more accurate measure of the amount of income  including the cost of these items , determining the useful life of old tractors , replacement age, cost of the process changes and the possibility of examinin...

In last years, trust and reputation has been gaining increasing interest in multi-agent systems (MAS). To address this issue, we propose in this paper a maintenance-based trust mechanism for agents operating in multi-agent systems. In the proposed model, a comprehensive trust assessment process is provided to assess the trustworthiness of the participating agents. The main characteristic of thi...

We study on how to maintain long-term influence in a social network by proposing an agent-based influence maintenance model. Within the context of our investigation, the experimental results reveal that multiple-time seed selection is capable of achieving more constant impact than one-shot selection.
