Weibull Models is a comprehensive guide that integrates all the different facets of Weibull models in a single volume. This book will be of great help to practitioners in reliability and other disciplines in the context of modeling data sets using Weibull models.

While with  Parrel/Series Systems What failure rate must each component of a series system have, so that the The Weibull distribution does not apply, it is pure filler. Introduction. • Reliability of Series Systems of “n” Identical and We will first discuss series systems, then parallel and redun- underlying Weibull distribution:. For small t the hazard rate of the series system is nearly the same as that for the component with the smallest shape parameter.

If β = 1, there is a constant failure Let’s suppose that your components are modeled as a simple series system. Very easy right? Just multiply them. Sometimes is not that easy… Consider that the component’s reliability is provided in the following forms: Component (1): Weibull (β= 1.6 , η = 9,500) Component (2): Exponential (λ= 0.000087) The gamma distribution was addressed in [18], the Weibull distribution was modeled for a series parallel system in [17], the exponentiated exponential distribution was proposed for the parallel Weibull, W., 1951,“A “When the system operating time is the MTBF, the reliability is 37%” - Blanchard and Fabrycky R(t) 1.0 R(t)=e-λt 0.5 t MTBF. Series We define random variables X j for the components’ reliability with Weibull distributions parametrized by θ βη j j j=(,), that is, ( ) ( ) exp j jj j j x PX x Rx β θθ η >= = − (1) for x >0, β j >0 (shape) and η j >0 (scale).
