研究了一类具有n台同工机器和R个修理工的k （n:G）可修系统。在该多机系统中，既考虑了冗余依赖关系，又考虑了修理工的多假期策略。R修理工的所有假期都是独立且同分布的，并且与其他工序也是独立的。采用离散变换法和龙格-库塔法对机械维修问题进行了理论和数值分析。得到了冗余依赖性和修复能力对系统可靠性的影响。并通过一些特殊案例，深入分析了维修能力和冗余依赖类对系统可靠性的影响。(C) 2012爱思唯尔公司版权所有。
This paper studies a k-out-of-n:G repairable system with n identical machines and R repairmen. In this multi-machine system, both the redundant dependency and the multiple vacations policy for repairmen are taken into account. All vacations of the R repairmen are independent and identically distributed, and they are also independent with the other processes. By using the discrete transforms method and the Runge-Kutta method, the machine repair problem is analyzed theoretically and numerically. The influences of the redundant dependency and the repair capacity on the reliability of the system are obtained. Moreover, through some special cases, the insight on the effect of repair capacity and redundant dependency class on the reliability of the system is provided. (C) 2012 Elsevier Inc.
