Reliability Analysis for One-Shot Product with Weibull Lifetime Components ─ An Empirical Study

Article Preview

Abstract:

When the device is inspected only once, there are only two possible statuses either functioning or failed at the time of inspection. In this paper, we consider a series system consisting of two components with lifetimes following weibull distributions and a competing risks model is used to study the series system for quantal-response data. Based on the quantal-response data, the maximum likelihood estimates of parameters of weibull distribution are derived. The model is illustrated using a practical numerical example of two-component series products, and the statistical properties of the maximum likelihood estimators were studied via Monte Carlo simulation under three-stage inspected scheme for various sampling sizes. This study verified that the model is practical. This research results can be applied to the reliability analysis of one-shot products with Weibull components lifetime distribution and the stockpile storage performance test.
