具有两种失效状态系统的几何过程维修模型

A Geometric Process Maintenance Model for a System with Two Types of Failures

引入并研究了一类新的几何过程维修模型:假设系统失效时有可能出现两种失效状态,第一种失效状态可以维修,而第二种失效状态则导致更换系统.在对第一种失效状态的广义维修策略N下,确定了长期运行下的单位时间平均费用.本模型包含以往的维修模型作为特例.

The authors study a new geometric process maintenance model, in which the system has two types of failures when it fails. One is repairable, and the other can only be removed by replacement. Under the generalized replacement policy N for the first type of failure, the long-run average cost per unit time is determined.
