Comparison between explicit and approximate degradation data analysis for linear paths. (Spanish. English summary) Zbl 1149.62085
Summary: We use the concepts of degradation analysis as they relate to product reliability. Many failure mechanisms can be traced to an underlying degradation process. Degradation eventually leads to a weakness that can cause failures. There are several methodologies for the analysis of degradation data in reliability.
This paper compares the explicit degradation methodology with the approximate degradation analysis. Specifically we perform a simulation study for linear degradation paths to explore the different estimations of the cumulative distribution function \(F(t)\) given by each methodology and we find that the two methods are competitive. We illustrate the results with data from a laser life test taken from W. Q. Meeker and L. A. Escobar [Statistical methods for reliability data. New York, NY: Wiley (1998; Zbl 0949.62086)].
