General Statistical Procedures: Parameter Estimation Using Weibull Distribution, Reliability Test of Hypothesis, and Computation of Expected Number of Renewals

Abstract

This addendum details the statistical procedures used in preparing the report, Decision Risk Analysis for XM204, 105mm Howitzer, Towed Reliability/ Durability Requirements (AD-763 204). A computer program was developed for this study to simulate DT/OT II testing analysis of data, the decision made based on this analysis, and the funding implications of this decision. A two-parameter Weibull family was assumed to describe durability failures. The test results were used to estimate the two parameters for each subsystem: carriage, recoil system, tube, and breech. This was followed by a test of hypothesis which tested whether sufficient information was available to reject the hypothesis that the required durability had been obtained. The subsystem durability was then used to compute replacement requirements over the system lifetime.
