The failed components of repairable systems are replaced with spare parts that may have different failure distributions from those of the components that have failed.The spare parts may be either the same as new,better than new,or worse than new.This is the reality in maintenance engineering.Repair with better spare parts is defined as“super repair”.The failure distributions of the spare parts affect the availability of the components and their systems.A novel model is proposed to describe the availability of repairable systems across their operating time,at the level of their components,on the assumption that the failed components arc immediately replaced.The model functions with arbitrary failure distributions of spare parts.It can be used to compute the availability of components and systems not only under perfect and imperfect repair but also under super repair.
