Sample-size determination under double Type II censoring for exponential distribution

In this paper, under the double Type II censoring, the problem of sample size determination is studied. To solve the problem, we utilize the cost function based on the total time on the test as well as the mean squared error of the maximum likelihood estimator for the exponential parameter. Under restrictions on these two criteria, the upper and lower bounds for the optimal sample size is presented in the paper. Numerical computations have been done to illustrative the obtained results
