Operator skill level or adherence to SOP's Autonomous Maintenance Autonomous Maintenance means that operators and indirect personnel have a participating role in maintaining equipment.
There are seven steps to follow: Reduce the time to clean and lubricate. Make a schedule for periodic tasks 4 Conduct General Inspection Training Conduct skills training with inspection manuals and use general inspections to find and correct slight abnormalities in equipment.
Use visual gauges and if possible, those that give feedback signals such as an alarm. Create visual work instructions for the steps above.
Maintain reliable data and use it to continuously improve. Involve the operators in the development of the above steps, they will feel a higher degree of ownership in sustaining the program.
In the long term, ensure the operators have a stake in the program with routine tasks and responsibilities. Some of the variables to iron out before applying is the definition for "uptime".
A machine running at a fraction of its intended performance is likely not acceptable to be considered "uptime". Whatever decision is made, that it is applied consistently across all pieces of equipment.
What exactly is a "failure"? A complete stoppage is one more obvious answer. Some may also consider a "failure" once the item or equipment experiences a slowdowns or reduced performance from an ideal level, but don't actually stop the machine.
Again, whatever the definition is for failure, it should be uniformly applied to all pieces of equipment. Such examples are light bulbs, switches, torn belts.
There is also the debate of planned downtime. Robust TPM programs have planned downtime for maintenance and predictive tools may create planned replacements or repairs in effort to reduce unplanned downtime and variability in uptime performance.
Ideally, the higher the MTBF the better. However, it is likely to plateau at a certain point due to planned downtime and intended maintenance. Then the challenge becomes how to reduce the planned outages and get better life out of the components or items involved so these planned intervals can be expanded.
As above, it is important to clarify what exactly constitutes a failure and downtime vs uptime. Allowing this to continue can show a better MTBF than the story in its entirety should show. Better preparation, spare parts programs, predictive analysis, are methods to reduce the MTTR.
Not all repairs are equal.
What constitutes an acceptable repair? This should be defined in the definition of a failure as well. The machine should not only be "up", but it should be up to a certain level of sustained performance before the time can be counted as "uptime". Total Production Time PT: Examine, every interval between failure.
Each amount of time between each repair is one data point. And analyze is amount of time it took for a repair.
Each time to repair is one data point. If the data is normal, the apply the mean. If the data is not normal, then the median or mode may be more appropriate. This analysis may also indicate outliers such as a period time that was unusually long or short between failures. Perhaps the team can brainstorm the reasons why using the 5-WHY tool?
Was the repair done differently? Was the repair done be a different person or group of people? Was a different part s used? This can shed light on best practices or components that should be used again for a closer Design of Experiments DOE to find the optimal combination or best procedure.
It may be worth spending a little more money up front to use quality parts or perform a longer PM to save more time in the long run. The team will have to determine if this is acceptable.
The intention is to strengthen the requirement for equipment maintenance and overall proactive management.Introduction to TPM: Total Productive Maintenance (Preventative Maintenance Series) (English and Japanese Edition) [Seiichi Nakajima, Norman Bodek] on alphabetnyc.com *FREE* shipping on qualifying offers.
Total Productive Maintenance (TPM) combines preventive maintenance with Japanese concepts of total quality control (TQC) and total employee involvement (TEI).

The terms corrective and adaptive maintenance originate from software maintenance. In computer science, corrective maintenance is accomplished by removing bugs from software, hardware and the network, while adaptive maintenance describes the adaptive.
