Simplify preventive maintenance, schedule work orders and track inventory That's one of the answers. Another is that new technologies make new strategies possible. When new technology gives us a new ability, we can leverage it in a new strategy. For condition-based maintenance and predictive maintenance, for example, sensors mounted on your assets and equipment capture a constant stream of data that you can use to help determine when to schedule upcoming inspections and maintenance tasks.
Here, you use a program of inspections and tasks to find and fix small problems before they have a chance to become major problems. Preventive maintenance is basically the idea behind the old saying that “An ounce of prevention is worth more than a pound of cure. One way to understand the benefits of preventive maintenance is to analyze all the problems that are avoided. Default maintenance is simply following the manufacturer's recommendations for maintenance, including when to perform inspections and maintenance.
Basically, it's the same as condition-based maintenance, except that the data is analyzed to make accurate predictions about future failures. You now have the same condition-based maintenance costs, plus the additional cost of even more sophisticated software that requires even more specialized training for your staff. For assets that don't fit either of these descriptions, it probably makes more sense to use preventive maintenance. As with many other strategies, you don't have to make a difficult decision between strictly one or the other.
When an asset is newer, you can use default maintenance. Later, when you have created a maintenance and repair history, you can begin to adjust the schedule to best suit your specific situation. Choosing the right maintenance strategy starts with understanding your options, benefits, and drawbacks. Execution to failure tends to get a bad reputation, but for a specific asset class and equipment, it's the best option.
Use when things are difficult or impossible to maintain, cheap to carry in inventory, easy to replace, or not essential to your operations. Preventive maintenance helps you find problems ahead of time when scheduling inspections and tasks. It also saves you money and frustration because you can plan everything in advance. For default maintenance, everything is basically the same as with preventive maintenance, except that it follows a schedule set by the manufacturer, not by your department.
Condition-based and predictive by relying on sensors and special software to collect and analyze data from sensors installed directly on or near your assets. For conditions, the software looks for readings outside the preset parameters. For predictive purposes, the software analyzes the data to predict future failures long before they begin to develop. In the end, there is no one and only perfect strategy for all time.
You need to choose the combination that works best for your assets, adjust your focus as your assets age and your department collects data. In general, preventing a failure is simply much cheaper and safer than letting the equipment fail. In addition, preventive maintenance would have a much smaller impact on production than fault maintenance (ie,. If what I consider to be condition-based maintenance, you call predictive maintenance, that doesn't really matter.
Ideally, inspections should be scheduled, completed on time, and documented with a maintenance management system or similar maintenance software. I appreciate your great efforts and informative articles and I am interested in reliability (especially the RCM) and maintenance scheduling, so I ask you about planning preventive maintenance activities. Instead, download The Types of Maintenance Tool Kit and learn what type of maintenance to use and when. One of the main reasons predictive maintenance is so valuable is because it allows maintenance to be performed only when absolutely necessary, that is, just before equipment failure occurs.
When choosing corrective maintenance as a strategy, it is essential to ensure that the failure modes considered do not have the potential to become emergency maintenance. The opposite of planned maintenance is unplanned maintenance, which has not been properly prepared and is planned in the plan as the work is done. I prefer to maintain the planned and unplanned distinction for (corrective) maintenance to identify those maintenance tasks that have not been planned i. Predictive maintenance requires a level of technology that standard preventive maintenance does not require, and may also require employees who can accurately interpret condition monitoring data.
In addition to being the result of a deliberate run-to-failure strategy, corrective maintenance is also the result of unplanned failures that were not prevented by preventive maintenance. Time-based maintenance is basically a type of maintenance that is performed at regular intervals while the equipment continues to operate in order to prevent failures or reduce the likelihood of failure. An efficient and effective preventive maintenance program will have a combination of all of these different types of maintenance. I prefer to use the distinction between reactive and proactive more around the general maintenance culture rather than maintenance tasks.
Unfortunately, books rarely specify this distinction, leading to mixing oranges and apples under the same general term of “maintenance tasks”, which is not precise enough to correctly describe the other maintenance concepts within preventive maintenance. Preventive maintenance occurs when maintenance tasks and plans are proactively initiated to prevent failures from occurring. . .
