We consider a life testing experiment in which several two component shared parallel systems are put on test, and the test is terminated at a pre-designed experiment. The bivariate data obtained from such a system level life testing can be classified into tree cases: ① the case of failed two components with known failure times, ② the case of one censored component and the other failed component of which the failure time might be known or unknown, ③ the case of censored two components. In this thesis, the maximum likelihood estimators of parameters for Block and Basu bivariate exponential distribution under above censoring scheme are obtained and the results of comparative studies through simulations are presented.
