Behavior of dynamic preventive maintenance optimization for machine tools

This paper presents an approach to the dynamic optimization of the preventive maintenance schedule for machine tool components during operation based on the actual operating life and the respective load profile. Therefore, a stochastic model based on the Weibull cumulative damage generalized log-linear model and the Monte Carlo simulation is used. Furthermore, the effect of the dynamic optimization on component selection for different maintenance strategies is taken into consideration. The ideal strategy can be selected from corrective, preventive and condition-based maintenance for every component of a complex system.
