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). 


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. 


This article relates to the textbook because it shows different ways that companies can use preventive maintenance to cut down cost and to keep the machines running longer. “An item is replaced either on failure or on the predetermined replacement time, whichever comes first” (Cha, Finkelstein, & Levitin, 2017). This process has to be timed out to get the full benefits of extending the lifetime on the machines. Without the timing process, it will be hard to know when the machine needed the tune up and it would be hard to track who would do it. This system is always changing and it is important to keep up with it.

The authors of this article explain the importance of making a schedule for preventive maintenance. The first step is to figure out which plan would work for the specific company. The next step is to decide how often the machines will go under maintenance. This is important to understand and create because it allows the machine life to be extended and will save the company money.

The authors of this article describe the different types of methods that can be used for preventive maintenance. This article shows the two different types of preventive measures such as the time-scale and the shock process.

The authors of this article describe how preventive maintenance helps to reduce the probability of breakdowns and failure. When a company invests in this program it has all sorts of benefits that can save the company more money. The more that a company can save, the more they can invest in other things to advance their production.
