In this study, recovery factor was considered in the maintenance management model that integrates the quantitative method and qualitative concept. The model is developed to solve the practical parameters in a maintenance management task, such as the number of maintenance personnel and maintenance cycle time. The stochastic model is applied to construct the relationships among maintenance cycle, maintenance personnel allocation, human recovery factor, and a system's tolerance time. In addition, a simulated experiment was conducted to find out the supplementary parameters such as individual latent human error, individual critical human error, recovery rate, and a system's tolerance time. Since system availability is the criterion of this maintenance management model, the final solution of this model provides a system availability reference table of the combination of the number of maintenance personnel and the maintenance cycle time. This system availability reference table is a practical tool for maintenance managers.
