consecutive -out-of- structure, consecutive system

An ordered sequence of components such that the system fails if and only if at least consecutive components fail. It is a consecutive -out-of-: -system if it works if at least consecutive components work. These systems are called circular, respectively linear, if the components are arranged in a circle, respectively on a line.

The reliability of such systems, which in simple cases amounts to probabilities of runs of consecutive successes or failures of Bernoulli trials, has connections with Fibonacci polynomials and Lucas-type polynomials (see Lucas polynomials).
