Operational research is a significant part of management, based on improving efficiency, operability, and machine quality. Those improvements influence the time of the repair process, workforce availability for the repair process, safety, and environment. The main goal of this article is to investigate the optimal – operating service life of the machine and the optimal – operating time interval for the renewal of the CNC metalworking machine. The research was implemented in a small enterprise in Slovakia that needed a CNC machine in the production process. The research hypothesis was determined H1: Using quantitative models of operational research can manage the machine’s life cycle. We used quantitative mathematical models of operational research. By calculation, we found that the optimal – operational lifetime of the CNC machine is 6 years. The renewal time of the machine is between the 5th and 6th year of use with a minimal level of the total costs for repairs and maintenance. This simulation is essential information for the financial plan for CNC machine renewal. The results of the research showed a confirmed hypothesis. The suggested proactive model is a viable instrument for the machine park in small enterprises with various orientations.
