(Pr\'edictions Bayesiennes en fiabilit\'e: cas d'une loi exponentielle.)} \itemso{Ann. I.S.U.P. 48, No. 1-2, 3-17 (2004).} \itemab Summary: We consider Bayesian prediction of order statistics and functions thereof from observations made on a first sample and with different types of data. Besides the predictive density, a predictor has been found in each case and for an exponential distribution. We adopt the conjugate form for the prior distribution of the parameter. In order to compute predictors and predictive intervals of the first order statistic, we present some simulations whose data are of attribute type. \itemrv{~} \itemcc{} \itemut{order-statistics; prior density; predictive density} \itemli{} \end
