摘　　要：现场故障更换对象由电子和机电元器件改变为电子和机电更换模块后,备件保障就成为联机检修冗余结构任务可靠度和使用可用度模型中必须包含的一个关键参数。但在传统的联机检修任务可靠度和现行的使用可用度模型中没有得到或没有完全得到应有的反映。对此,提出了修正模型。在使用可用度模型中还对同时检修的平均修复时间模型作出了改正。After the replacement object for field failures changed from electronic and mechatronic components to electronic and mechatronic replacement modules, the spares supportability has become a key parameter in the mission reliability and operational availability mode] of the redundant structure for online maintenance. However, it has not been reflected properly in the traditional mission reliability and operational availability model for online maintenance. To dealing with this issue, a modification model is pro The MTI＇R model in the operational availability model was modified at the same time.
