A cold standby repairable system with working vacations and vacation interruption following Markovian arrival process

This paper studies a cold standby repairable system with working vacations and vacation interruptions. The repairman's multiple vacation, the working vacation policy and the vacation interruption policy are considered simultaneously. The lifetime of component follows a Phase-type (PH) distribution. The repair time in the regular repair period and the working vacation period are other two Phase-type distributions with different representations, and the successive vacation times are governed by a Markovian arrival process (MAP). For this system, a vector-valued Markov process is constructed. We obtain several important performance measures for the system in transient and stationary regimes applying the matrix-analytic method. Finally, a numerical example is given to illustrate the results obtained in the paper. (C) 2015 Elsevier Ltd. All rights reserved.
