Sensitivity analysis of a hydroelectric production power plant under reworking scheme using fuzzy AHP approach

Published: Mar 12, 2018 by CHINA
Authors: Mangey Ram, Ritu Chandna

This research work aims to evaluate the sensitivity of the hydroelectric system, taking the human failure into consideration using fuzzy analytic hierarchy process (AHP) approach. Six different failure rates are taken into consideration. The fuzzy approach incorporates all the vagueness and uncertainty existing in the power system due to different failure and repair rates.


Bi-directional system analysis under copula-coverage approach

Published: Jul 11, 2017 by USA
Authors: Mangey Ram, Nupur Goyal

Reliability assessment is a major step, toward the development of fault-tolerant computing system. In different fields of engineering and physical/ailed sciences, researchers or engineers have several reliability approaches for the better performance of the system.


An Approach to Investigating Reliability Indices for Tree Topology Network

Published: Aug 12, 2016 by AUSTRIA
Authors: Nupur Goyal, Mangey Ram, Ayush Kumar Dua

Due to advance technology, rapidly emergent complexity of networks and perseverance on network quality, reliability, and maintainability are progressively significant issues, and hence, the job of reliability analysts is becoming more challenging. A network’s optimum design is required for maintaining the reliability of a sophisticated network at a high level.


Numerical solution to stochastic partial differential equation with variable repair rate

Published: Jan 11, 2016 by USA
Authors: Mangey Ram, Arpan Gupta

In this paper, a numerical solution technique to stochastic partial differential equations in reliability engineering is presented. The method is based upon finite difference discretization of the governing equations for the Markovian reliability model. In realistic situations, the repair rates and failure rates of engineering system are variable.


Performance Evaluation of a Multi-state System Covering Imperfect Fault Coverage

Published: Nov 04, 2014 by USA
Authors: Mangey Ram, Monika Manglik

Fault-tolerant networks are being used to provide more reliable network connections. Development of the fault-tolerant computing system requires accurate reliability modeling. Numerical formulations and complex models are commonly used for obtaining reliability measures.


Behavioural analysis of a hydroelectric production power plant under reworking scheme

Published: Jan 24, 2014 by USA
Authors: Monika Manglik, Mangey Ram

By high calibre of the fundamental nature of electric power, both of our economic and personal interests, a system is expected to supply as electrical energy as possible with the highest degree of quality and reliability. This research work aimed to evaluate the reliability measures of a hydroelectric power station.
