Life Test Sample Size Determination Based on Probability of Decisions (基于决策概率的寿命试验样本容量确定)

Jiliang Zhang
Jiliang Zhang was born in Nanjing, China. He received his B.S. in 1983 and M.S in 1986 in Heat Energy Engineering, both from Hauzhong University of Science and Technology, China. He attended the Ph. D. program in Reliability Engineering at The University of Arizona from 1995 to 1999. He then worked for Hewlett-Packard Co. and in reliability and quality field. He is currently the Staff more


In a reliability evaluation test, one could end up with one of decisions of the reliability specification being met, not met, or inconclusive. In this presentation, we present a methodology of sample size determination prior to the test based on the probability of reaching these decisions. The specific results are obtained for the cases of Exponential distribution and Weibull distribution with a known shape parameter.
