Abstract:

This volume provides a detailed procedure for visually determining the applicability of the exponential, truncated normal, logarithmic normal, gamma or Weilbull distribution as the appropriate survivorship function of life test or fleet failure data and for estimating the appropriate functions parameters and life quality characteristics from the data. Also presented is a practical nonparametric method estimating life quality characteristics of life test or fleet failure data at different confidence levels. To illustrate the practical applicability of these procedures two graphical reliability analyses of actual failure data are presented. The first analysis is of fleet failure data on the ANSPS-10 covering the time period from November 1962 to August 1963. It consists of thrity-five 35 recorded times to failure. The second analysis is of censored field failure data on tubes from a group of fixed ground station communication receivers. It consists of forty-eight 48 recorded times to failure and sixty-eight 68 recorded times to suspension. The detailed procedures step by step methods used are presented in referenced sections following these analyses. Author
