It is an important matter to decrease the mean time to repair (MTTR) for the improvement in the reliability of machinery. When factory workers repair as infrequent operations, they usually don't have a service manual. Therefore, the quality of repair is dependence on the skills of maintenance engineers or machine operators. In maintenance planning, repairs as infrequent operations have a tendency to depend on skilled workers. However, in the case of infrequent operations, there is not always correlation between the experience of maintenance engineers and the decrease of MTTR or repair time. This is an important problem in the optimum maintenance planning. And the industrial world desires the analysis of the human factor which affects the reliability of machinery. In this research, we turn into a model the actions for coping with the failures of maintenance engineers, and analyze the human factor which affects the reliability of machinery. In addition, we consider the improvement in the reliability of machinery by the reduction of MTTR or the repair time. However, in infrequent operations, there is not always a correlation between the experience of maintenance engineers and the reduction of MTTR or repair time.
