Abstract
EN We consider coherent and mixed systems composed of components with independent identically exponentially distributed lifetimes. We describe sufficient conditions assuring specific properties of the system lifetime density and failure rate functions expressed in terms of the system Samaniego signature. In particular, we determine conditions which guarantee monotonicity, unimodality, and strong unimodality of the density function, and monotonicity of the failure rate and mean residual life.
