Many centroid-based clustering algorithms cannot guarantee convergence to global optima and suffer in local optimal cluster center because they are sensitive to outliers and noise. A heuristic optimal technique like particle swarm optimization (PSO) can find global optimal solution with the cost of extensive computation. In this paper, a PSO based(More)
The recent deployment of complex and capital intensive equipment in mines has resulted in increased interest in the maintenance and operational reliability of these equipments. This is because random equipment failure has consequences that influence the total operating cost of this system. This case study analyses the reliability of a fleet of load haul(More)
The unexpected failures, the down time associated with such failures, the loss of production and, the higher maintenance costs are major problems in any power plant. Riskbased maintenance (RBM) approach helps in designing an alternative strategy to minimize the risk resulting from breakdowns or failures. The RBM methodology is comprised of four modules: viz(More)
This paper surveys the literature related to maintenance policies for single and multi -unit systems. The emphasis is on work appearing in different periods. The literature is divided into two main categories Single and multiunit system. The single unit system is divided into six sub-categories like: Age-dependent, Periodic, Failure limit policy,(More)
Reliability analysis for Gas turbine power plant over a period of 66-month was carried out. The most important failure modes units were identified and the descriptive statistics at failure and machine level were calculated. Several theoretical distributions were applied and best fit of failure data was identified. The reliability and hazard rate models of(More)
Wind is one of the cheapest and widely source of alternative energy. To convert it into electrical energy a wind turbine with generator is used but to properly convert this wind energy into electrical energy proper design of wind turbine is needed. In this paper we presents a genetic algorithm based optimization technique for the estimation of wind turbine(More)
