Estimation of stress-strength reliability for a non-identical -component-strengths system based on upper record values

Motivated by the lack of literature on multicomponent stress-strength models based on record values, this thesis is an attempt to produce more realistic stress-strength models by deviating from the much studied traditional way of assuming identical strengths for system components. The thesis considers the estimation of stress-strength reliability in a multi-component system with non-identical component strengths based on upper record values from the family of Kumaraswamy generalized distributions
