closely linked. If weassume that several component’s life of a mechanical system are all follow life distribution, it is necessary for us to compare the mean life of these parts, timing to replacement and maintenance of these components to ensure the reliability of the product; In experimental design we often consider comparing the life of one or more reference products or one of more test products. Therefore, all pairwise differences of mean life of two or three products have become the urgent problem to address. It is typically assumed that the product life follows a two-parameter exponential distribution Exp(µ, θ), thus its mean life is δ = µ + θ, and the question of interest is to compare the differences δ’s from several such distributions. Surprisingly, to the best of our knowledge, the literature seems scant in this area. In this paper, we will try to fill this void by constructing simultaneous confidence intervals (SCIs) for differences of two-parameter exponential means using a parametric bootstrap (PB) method. For more about the two-parameter exponential distribution family, seeLawless (1982),Mauryaet al.(2011) and the references therein.
