The next round of preventive maintenance on the fan would not occur when it has run for 200 hours, as it would on a fixed schedule. However, because your facility had a tight deadline and a large order to process, the fan operated for 120 hours, at which time it was serviced. Let’s say a fan is scheduled for maintenance every 100 hours of operation. Let’s use an example of floating preventive maintenance scheduling with a usage-based trigger. That is why it takes a little extra diligence to track and use floating preventive maintenance scheduling. If a work order is left open, it means the next PM will not be triggered.

If this PM schedule is floating, it means the work order is not created 10 days from when the last PM was supposed to happen, but rather 10 days from when it is actually completed, regardless of if it’s on time or late.

Instead, the date of the work order changes depending on the maintenance history and/or past usage of an asset.įor instance, let’s say the preventive maintenance interval for an asset is 10 days. These tasks do not have a specific date attached to them. What is floating preventive maintenance scheduling?įloating PMs are preventive maintenance tasks that are scheduled based on the timing of the previous PM. A fixed schedule means this late PM isn’t taken into account when scheduling the next one - the vehicle is serviced at 2,000 miles, not 2,200 miles. Because the PM is set up on a fixed schedule, the next PM will trigger when the truck has been driven 2,000 miles, regardless of how long it takes for that to occur or the circumstances in which the truck has been driving.īut let’s say that the truck is on the road when it hits 1,000 miles and the PM can’t be completed until it has 1,200 miles of use. As soon as the odometer rolls from 999 to 1,000, a PM is triggered and a work order is created. Your facility might have a truck that requires maintenance every 1,000 miles. Since a time-based PM was covered in the section above, let’s take an example of fixed preventive maintenance scheduling using a meter-based trigger. The schedule does not account for what has happened in the past, only for what is planned for the future. Even if last Monday’s task was completed on Wednesday, or was never completed at all, a new work order is triggered for the following Monday. Fixed PM scheduling helps plan work based on the target start date of the previous work.įor instance, a PM may be scheduled on an asset every Monday. What is fixed preventive maintenance scheduling?įixed preventive maintenance scheduling is when regular maintenance is scheduled at a certain time or usage interval, regardless of when the last PM was completed.
