The main aim of this paper is to define what imprecise reliability is, and discuss a variety of problems that can be solved by means of a framework of imprecise probabilities. From this point of view, various branches of reliability analysis are considered, including analysis of monotone systems, repairable systems, multi-state systems, structural reliability, software reliability, human reliab...

In recent years, grid technology has emerged as an important tool for solving compute-intensive problems within the scientific community and in industry. To further the development and adoption of this technology, researchers and practitioners from different disciplines have collaborated to produce standard specifications for implementing large-scale, interoperable grid systems. The focus of th...

Reliability investigation has always been one of the most important issues in power systems planning. The outages rate in power system reflects the fact that more attentions should be paid on reliability indices to supply consumers with uninterrupted power. Using reliability indices in economic dispatch problem may lead to the system load demand with high reliability and low probability of powe...

of Section II Section II, "A Comparative Study of Heuristic Reliability Optimization Methods" investigates the effectiveness of a mixed-integer programming method. This method is a combination of the heuristic redundancy method and the sequential search method. The heuristic method determines the integer variables (number of redundancies) by assuming that the real variables (reliability level) ...

In this paper authors have considered a system having three units A, B1 and B2. A is controlled by a controller and B1 and B2 are independent. Two repairmen are involved in repair of the system. One of the repairmen (the first) is the foreman (boss) and the other an assistant (apprentice). Whenever any unit fails, repair is undertaken by boss. If the boss is busy in repairing and at the same ti...

Reliability is a fundamental factor in the operation of bus transportation systems for the reason that it signifies a straight indicator of the quality of service and operator’s costs. Todays, the application of GPS technology in bus systems provides big data availability, though it brings the difficulties of data preprocessing in a methodical approach. In this study, the principal component an...
