摘要
The TTT-plot (TTT = Total Time on Test) and its theoretical counterpart, the scaled TTT-transform, were introduced in 1975 by Barlow & Campo and used for model identification of complete samples from non-repairable units. Since then various applications of TTT-plotting, intended for data from non-repairable units, have been presented. This paper illustrates how the TTT-plot can be used as a basis for goodness-of-fit tests for the power-law process when data are available from a repairable system. Both a subjective graphical procedure and an analytic test procedure based on the cumulative TTT-statistic are studied.
