Abstract

The periodically inspected system availability of two-components repairable system with a perfect repair policy under arbitrary lifetime and repair-time distributions is studied in this paper, an analytical availability model is presented for system adopts a recursively method. The general expression of two-components repairable system availability under structure forms of series, parallel and standby are obtained and calculated, the calculation results illustrate that this model accords with the physical law of the system, which laid a solid technical foundation for complex periodical inspection equipment availability calculation. Finally, a Weibull-normal distributed subsystem is study to analyze the relationship between inspection periodic and availability. This simulation achievement provides technology support for improving system availability and determining reasonable inspection period.

Key words
