Abstract

Bounds for aging properties in mixtures and their derivatives are provided. Such bounds allow control of the behavior of those characteristics through the aging properties of the distributions in the mixture. We also obtain some results for discrete mixtures involving exponential distributions. In addition, well-known mixture-preserving properties for several distribution classes are derived with little algebraic complexity.
