The definition of preventive maintenance is as follows “Proactive approach; reducing breakdowns through a program of lubrication, adjustment, cleaning inspection, and replacement of worn parts” (Stevenson, 2021).
Summary:
In the article, Linear and Nonlinear Preventive Maintenance Models, the authors Wu and Zuo discuss the importance of the preventive maintenance model and how it improves the lifetime of equipment. “A better maintenance decreases the hazard rate and/or virtual age of a system, whereas a worse one increases them, or even brings the system to fail or break down” (Wu, & Zuo, 2010). The authors agree that there are three different types of preventive maintenance models and these are called perfect, minimal, and imperfect. It is up to management as to which one they would like to use in their company. A perfect system is when the machinery is restored to what it was when it was brand new. The minimal model is to keep the machinery going until a full maintenance can be done on it. The imperfect model basically does no preventive maintenance and allows the machinery to run until there is an issue.
