For those of you who’ve never heard the term before, “Overall Equipment Effectiveness” (OEE) is amethod of analysis, which was developed in Japan, by the Japanese Institute for Plant Maintenance (JIPM).
It was made so as to create transparency and seek outany type of losses in manufacturing production in three classifications:
- Availability
- Rates of Performance
- Rates of Quality
As a device, OEE producesinformation on losses and also displays methods of tackling those losses in a slimmed down manufacturing style to:
- Increase operating margins
- Enhance the means of competitive performance to improve the company’s reputation
- Generatethe quality of a product that will then get a good return on investment
- With the use of metrics that display manufacturing efficiency, it will provide comparison values over a spectrum of various manufacturing products.
- And will handle not only what advancements should be made, but also how much any advancements will affect the bottom line.
Making the Most in Performance
By the measuring and analysis of standard machinery and means, OEE identifies the most effective use of equipment in use and will even advise against investment in more machinery if the needs be.
Altering how equipment is being used can:
- Removeobstacles
- Put excess capacity to usage
- Anticipate downtime losses
General equipment efficiency analysis is priceless in helping to reduce complex production problems to easy, informative presentations.
It plainlydelivers to the management, the data they need to manage and reduce wasted time and effort in different areas and go on to produce higher quality products as a result.
Broken Down into Three Categories
1 –
- The first of the three categories, availability, is the trusted availability of expected production over a time period of 24 hours a day, seven days a week and 365/6 days per year.
- This metric is known as the uptime, which takes into account any downtime loss, and its rule is availability equals actual working time divided by planned production time.
2 –
- The second of the categories is performance rates. This represents the running speed of a production plant as a percentage of its designed speed.
- This will consider and take into account any losses in speed, and its final formula is worked out as performance equals units produced multiplied by the wished for time divided by actual time.
3 –
- The third and last of these three categories of OEE is the rate of quality, the number of perfect units which were produced out of the total amount of units started with when put into production.
- This is the process of the production of labour, and it’s right here that the analysis will at last begin displaying what measures are needed to make changes.
Product quality is always an opportunity for the best return on assets, so an improvement in the ratio of good units and a reduction of rejects will improve no end the company’s profits and reputation.
