Usually, systems and components are described as being in one of two modes, “on”or “off.” Such systems are described using binary structure functions. In multistatesystems (MSS), components can be in more than two states—for ...

Most real life system exhibit bathtub shapes for their failure rate functions. Generalized Lindley, Generalized Gamma, Exponentiated Weibull and xExponential distributions are proposed for modeling lifetime data having ...
