A method to generate disjoint spanning trees and hence to compute source to all terminal(SAT) reliability of acyclic directed networks is proposed in this paper. SAT reliability of a directed network is defined as the probability that there exists a minimal spanning tree from source node to all terminal nodes of the network. The method initiates with a specific directed spanning tree and produces...
Heuristic redundancy optimization with ST (Source-Terminal) reliability measure for complex network; an extensively studied problem has been modified to heuristic redundancy optimization with SAT (source to all terminal) reliability measure.
Source to all terminal reliability of a network is the ability of the network to transmit the commodity from source node to all other terminal nodes. The paper proposes an algorithm for source to all terminal reliability evaluation of directed networks. The algorithm starts with a spanning tree which is termed as first spanning tree (FST). All other disjoint spanning trees are generated from the knowledge...
Reliability and performance of the parallel processing system greatly depends upon the topology of its interconnection network through which all processors are attached to themselves or to its memory modules necessary in parallel and efficient computation. In this research paper an already existing class of interconnection networks i.e. PM2I has been analyzed extensively for their better performance...
Risk is the probability that an unwanted event may happen in the future that will effect in some harmful consequences. Risk analysis and maintenance of risky components of a system is essential to protect the system. Reliability Importance measures play an imperative part in ranking the components according to the impact on the system reliable performance. Risk based measures are useful in identifying...
Reliability modeling in terms of Reliability block diagram (RBD) of different configurations of power electronic converter has been implemented. Literature survey reveals that failure of the power electronic converters is one of the main causes of the wind turbine failure in variable speed wind turbines. Failure rate, repair rate, reliability and availability are computed for existing configuration...
In system reliability analysis component importance plays major role for prioritizing the components in the system to improve the reliability, risk and maintenance planning. Maintenance of all the risky equipments is necessary to ensure successful operation of any system. Different importance measures are available to compute the rank of the component for improving the system reliability and maintenance...
Uncertainty measurement and risk analysis play a vital role in manufacturing industry where not only monetary and time costs are involved but lives of human beings may also be endangered. Importance analysis is performed to determine the critical actions and to prioritize maintenance tasks. In the present paper, various importance measures for the Reverse Osmosis Plant have been calculated and the...
