AIE conducts maintenance optimisation using a variety of techniques in order to improve existing conservative OEM derived maintenance strategies including:
- Modifications on the schedule and frequency of the planned maintenance routines can be focused towards failure history and reliability of the equipment.
- Similar PM tasks can be grouped together, and unnecessary maintenance tasks are omitted and optimised.
- Required availability of the equipment can be used in order to optimise maintenance tasks, both the requirement of the task and the frequency of the task.
A Planned Maintenance Optimisation programme is estimated to reduce overall maintenance costs by around 20%-30%. Payback periods are estimated at around 12 to 24 months, just considering the measured savings from maintenance costs. This also allows resources to be spent more wisely without sacrificing the quality of execution of maintenance tasks. The biggest key to conducting a successful maintenance optimisation is data.
- Critically review all current preventative maintenance work. Focus on labour costs, spare parts and compare with equipment reliability and production time
- Conduct asset criticality assessment. Is failure really a problem?
- Carefully measure the preventative vs corrective maintenance ratio
- Make use of data
- Use a CBM approach to assess the need for maintenance. Do not rely on flawed indicators such as age or condition
The implementation of any optimised frequencies, changes to PMs, resources, etc. is achieved through AIE's Veracity Software's integration with CMMS. Automatically produced CMMS loadsheets can be seamlessly integrated by ensuring Veracity is configured as per client CMMS.
