Use of copula functions in error assessment due to deviation from dependence assumption
Subarna Bhattacharjee, Aninda Kumar Nanda, Subhashree Patra
In this paper, we analyze the relative errors in various reliability measures due to the tacit assumption that the components associated with a -component series system or a par…
Use of stochastic orders and statistical dependence in error analysis for multi-component system
Subarna Bhattacharjee, Aninda Kumar Nanda, Subhashree Patra
In this paper, we analyze the relative errors that crop up in the various reliability measures due to the tacit assumption that the components are independently working associated…
Use of Lambert W function in the simulation of Weibull and non-Weibull distributions
Subhashree Patra, Subarna Bhattacharjee
In this work, we have taken up some distributions, mostly Weibull family, whose quantile functions could not be obtained using the traditional inversion method. We have solved the…
Geometric and Harmonic Aging Intensity function and a Reliability Perspective
Subarna Bhattacharjee, Ananda Sen, Sabana Anwar +1
In this paper, we introduce some new notions of aging based on geometric, harmonic means of failure rate and aging intensity function. We define a generalized version of aging func…
On weighted failure rate, its means and associated quantile version
Subarna Bhattacharjee, S. M. Sunoj, Sabana Anwar
In this paper, we define weighted failure rate and their different means from the stand point of an application. We begin by emphasizing that the formation of n independent compone…
Errors due to departure from independence in multivariate Weibull distributions
Subarna Bhattacharjee, Aninda K. Nanda, Subhasree Patra
We do the error analysis in reliability measures due to the assumption of independence amongst the component lifetimes. In reliability theory, we come across different n-component…
