A bivariate mixed policy for a system with multistate failure. (19th May 2018) - Wei, Yiqing
Abstract: The paper studies a geometric process model with multistate failure based on preventive repair. Assume that the system has two types of failures when it fails. One is minor failure that a new system is installed after the N th failure, the other is catastrophic failure that the system can only be removed by replacement. The preventive repair is adopted when its reliability drops to an undetermined constant R . An optimal replacement policy ( R, N )* is determined by minimizing the average cost rate. Finally, a numerical example is studied that the operating time of system is a Weibull distribution.
