This paper presents an application of mathematical modeling oriented to maintenance management based on the delay time concept. The study scenario was the manufacturing sector of an industrial unit which operates 24 hours a day in continuum flux of production. The main idea was to use the concepts of this approach to determine the optimal time of preventive action from the maintenance department to ensure greater availability of equipment and facilities while introducing appropriate maintenance costs. After a brief introduction on the subject (section 1), the article presents in section 2, topics that illustrate and underscore the importance of mathematical modeling applied to the maintenance management and delay time concept. Session 3 shows the characteristics of the company where the study was conducted, as well as data relating to the production process and maintenance actions. Section 4 presents the results obtained after applying the delay time concept and finally, these results are discussed as well as the limitations of the article and the proposals for future work (section 5).
