Multivariate Tests for Comparing Lifetimes of Parallel Systems

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Life testing of engineering systems with dependent components requires robust multivariate methods. Parametric approaches depend on restrictive assumptions, limiting their use in complex or unknown lifetime distribution settings. This study evaluates nonparametric methods for comparing parallel system lifetimes under minimal sample ...
