An integrated intelligent algorithm is proposed to optimize the reliability, maintainability, and total cost in job shop production system. The consists of three basic modules computer simulation. each comprising phases Algorithm, simulation, Experiments/robustness validation. In design phase, different scenarios are determined by changing parameters affecting cost. system simulated simulation ...

A. Abstract In 1995, an improvement project was completed on the 244 klystron modulators in the linear accelerator. The modulator system has been previously described [ 11. This article offers project details and their resulting effect on modulator and component reliability. Prior to the project, we had collected four operating cycles (1991 through 1995) of MTTF data [2]. In this discussion, th...

Modeling the reliability of distributed systems requires a good understanding of the reliability of the components. Careful modeling allows highly fault-tolerant distributed data applications to be constructed at the least cost. Failure and repair rates of components are often assumed to be exponentially distributed. This hypothesis is testable for failure rates, though the process of gathering...

The concerned study pertains to the development of a new stochastic model for reliability analysis linear consecutive-k-out-of-n: G system, where k>n2. In developed model, system may collapse as result common cause failure or hardware in its units. has exponentially distributed rates, and case breakdown, it is repaired with copula method. been examined through supplementary variable techniqu...

The structures for the expression of fault-tolerance provisions into the application software are the central topic of this dissertation. Structuring techniques provide means to control complexity, the latter being a relevant factor for the introduction of design faults. This fact and the ever increasing complexity of today’s distributed software justify the need for simple, coherent, and effec...

We investigate two types of fault tolerant units (FTU’s) suitable for dependable distributed control systems and numerically evaluate their reliability and mean time to failure (MTTF). A simple simulation-based methodology to numerically evaluate dependability functions of a wide variety of fault tolerant units is presented. The method is based on simulation of stochastic Petri Nets. A set of 1...

The design of a suitable interconnection network for inter-processor communication is one of the key issues of the system performance. The reliability of these networks and their ability to continue operating despite failures are major concerns in determining the overall system performance. In this paper a new irregular network IASEN (Irregular Augmented Shuffle Exchange Network) has been propo...

In the present investigation, we deal with the reliability characteristics of a repairable system consisting of two independent operating units, by incorporating the coverage factor. The probability of the successful detection, location and recovery from a failure is known as the coverage probability. The reboot delay and common cause shock failure are also considered. The times to failure of t...

The effectiveness and reliability of the unified power flow controller (UPFC) are determined by insulated gate bipolar transistor (IGBT) valve. Thermal losses, conduction switching losses in IGBT valve all affect efficiency UPFC. failure rate converter valves is influenced junction temperature, which has an impact on converter's reliability. Piecewise linear electrical circuit simulation (PLECS...
