Maximum-Likelihood Estimation of the Parameters with Constraints in Step-Stress Accelerated Life Tests

Abstract:

Article Preview

This paper investigates the maximum likelihood estimation of the average lifespan of products with the constraints, and the estimation of the average lifespan at stress level, which follows the exponential distribution, is derived by transforming the time-censoring step-stress accelerated life test data into the corresponding constant-stress accelerated life test data. The proposed method can overcome the shortcoming of information lose.
