The Parameter Estimate of the Exponential Distribution Based on the Tampered Failure Rate Model under the Multi-step Stress Accelerated Life Testing

Zheng Yu-tang

Abstract

Under the multiple step-stress accelerated life testing,the text discussed the methods of parameter estimate based on grouped data built on the assumption of the time formula of TFR model.The result of Monte Carlo simulation intuitively explained that the methods were fit for large specimen.
