Abstract:

This volume describes the study which was conducted to assess the effects of inferences based on the exponential assumption when the truncated normal, logarithmic normal, gamma or Weibull distribution is applicable and to provide the Bureau of Ships with a nonparametric method of reliability analysis. The objectives of this study were 1 to develop a practical criterion of and quantify the sensitivity of exponential life quality characteristics estimated from life test or fleet failure data when the survivorship function is truncated normal, logarithmic normal, gamma or Weibull, 2 to provide fast, simplified graphical andor mathematical reliability analysis procedures to determine the applicability of the exponential, truncated normal, logarithmic normal, gamma or Weibull distribution as the appropriate survivorship function of life test or fleet failure data and to estimate the appropriate functions parameters and life quality characteristics from the data and 3 to provide a practical nonparametric method of estimating life quality characteristics of life test or fleet failure data at different confidence levels.
