Overall Equipment Effectiveness (OEE)
Arran McDonald (Senior Consultant at Bourton Group LLP)
So, what is it? Key measurement or just a manufacturing concept?
Is it relevant to construction?
In these commercially challenged times we are under more and more pressure from our clients to deliver “more for less”. However, with challenging targets and tight programme objectives to be achieved, it’s difficult to understand how we can achieve them without increases in time and resource.
Key Measurement
OEE is a key measurement in the improvement approach called Total Productive Maintenance (TPM). TPM is used to improve the capability of a company’s equipment. It is a production driven methodology that drives to optimise equipment reliability and ensure effectual management of assets using employee involvement and empowerment.
It has several waste reduction goals, including keeping equipment working at its optimum capability with timely remedial works and maintenance. A clear definition of how equipment should be operated to reduce variation of output is necessary; incorporating safety checks, visual controls and mistake proofing of devices in daily work.
TPM also looks at the design of the equipment to hone its capabilities in line with the business requirements.
None of the above can be effective without a way to measure and denote a change to optimum conditions.
When we look at OEE there are three factors that are considered:
- Performance – a comparison of the actual output with what the machine should be producing or achieving in the same time
- Availability – a comparison of potential operating time and the effective working time of the machine
- Quality – a comparison of the output/products made by the machine to the output/products that meet the required specifications
When you multiply these three factors you get the Overall Equipment Effectiveness which is a great indicator of machine/equipment health.
Manufacturing Concepts in Construction
Is there such a thing as a manufacturing concept? Or are there just concepts or perhaps improvement approaches? The lines between industries are becoming even more blurred.
If you look at the Construction industry, some of the key business concepts that are currently being employed to be more effective are site based factory thinking, modularisation and offsite manufacture. This further extends to how site waste is being segregated and subsequently processed.
I am not suggesting that a construction site is exactly like a manufacturing facility in the way that it operates or should operate, nor am I suggesting that the construction industry and construction processes do not present a unique set of challenges. However, I do challenge that improvement concepts are unique to a single industry and that the same concepts cannot be applied to good effect across all industries.
Examples of OEE in Construction
Off hire of equipment – OEE could be used to support off hire of equipment decisions. There are many instances across the industry of diminished functioning of hired equipment.
To support planned use of costly equipment – such as cranes, trenchers or pipe welders
Support Plant maintenance/replacement schemes – setting of control limits for planned maintenance and strategic decision making
Benchmarking – equipment effectiveness across projects and programmes.
Optimising Material Recovery Facilities (MRF’s) – OEE can be a good health indicator that could monitor the effectiveness of improvement activities.
