ABSTRACT
Steady-state availability means that the whole equipment system gradually becomes steady after a long running-in period. Mathematically, this refers to the availability in case the operating time of the whole equipment system goes to infinity. Therefore, steady-state availability plays a very important role in our understanding of equipment operational readiness and continuity of mission through the whole service life of equipment. The steady-state availability parameters have been widely applied in various kinds of weapons to describe their operational readiness and continuity of mission, significantly promoting the equipment’s construction. One of the most critical objectives in future combat system research is obtaining higher availability. Reference [1] studies how to improve the reliability and operating availability of a complicated system and proposes a pre-diagnosis-based method. A series of Monte Carlo simulations are proposed in Reference [1], concerning a complicated system consisting of 300 platforms, where every platform is comprised of 20 key units. In addition, the system availability curves under different strategies are also given.
