The impact of the lack of independence hypothesis for system reliability of the vehicles seriaUnder the exponential distributionl


This research investigates the consequences of departures from independence when the component life times in a series system are exponentially distributed. Such departures are studied when the Joint distribution is assumed to follow a Gumbel bivariate exponential model systems with two components are studied. The system reliability and mean system life are computed and the effects of errors are studied based on life test data.
