Life test sample size selection under a Weibull failure model

摘要

In this paper, we consider sample size selection for life tests when the product life follows the two parameter Weibull distribution. Two situations are considered: 1) an acceptance test where the purpose is to determine whether the product under test meets specified or historical life objectives and 2) a routine endurance test where the purpose is to determine a parameter's value within a sufficiently small interval of uncertainty just to add to a growing body of knowledge and serve as an item of information in future as yet unformulated decision-making processes.
