针对单部件马尔可夫可修系统，提出了一种新的模型，使得系统的维修时间足够短（小于某个临界值），不会导致系统失效。我们可以说，这样的维修间隔是从停机时间记录中省略的。首先，我们假设临界修复时间是一个常数。然后将该模型推广到允许临界修复时间为非负随机变量。我们计算这些新型号的系统可用性作为可靠性的衡量标准。最后给出了数值例子来说明本文的结果。
This paper introduces a new model for a single-unit Markov repairable system in which repair times that are sufficiently short (less than some critical value) do not result in system failure. We can say that such a repair interval is omitted from the downtime record. First we suppose that the critical repair time is a constant. The model is then generalized to allow the critical repair time to be a non-negative random variable. We calculate system availability for these new models as a measure of reliability. Some numerical examples are given to illustrate the results in the paper.
