LONG-RUN AVAILABILITY OF A ROBOT-SAFETY DEVICE SYSTEM

Abstract

We consider a robot-safety device system attended by two different repairmen. The system is characterized by the natural feature of cold standby and by an admissible "risky" state. In order to describe the random behavior of the entire system (robot, safety device, repair facility) we introduce a stochastic process endowed with probability kernels satisfying general Kolmogorov-type equations. Next, we derive the long-run availability of the robot-safety system. Some numerical examples are provided. Finally, as an application, we consider the particular but important case of fast repair.
