Unlike series system where the weakest component limits the reliability, here by adding redundancy the system reliability improves. Thecombined system is operational only if both Part X and Part Y are available.From this it follows that the combined availability is a product ofthe availability of the two parts. During this correct operation, no repair is required or performed, and the system adequately follows the defined performance specifications. Terms.
