In this paper the maximum likelihood estimator is given for failure rate functions which are assumed to be non-decreasing step-functions on O,S. We assume that data arise from a testing plan based on replacement of failed items in a number of separate experiments. The testing plan considered allows for different maximum number of replacements in each experiment, allows for different total testing times for the experiments, and it also allows for withdrawals of some items before they fail.
