What Is OEE?

 OEE (Overall Equipment Effectiveness) reduces difficult and complex production issues into readable, well-presented, and usable information. Its measurement helps to improve your processes and can be used to monitor best practices on machines, assembly lines, and manufacturing cells.

Planned production time: To help find your planned production time you will need to know this equation; Plant operating time - Planned shut down time = Planned production time.

OEE will look at your planned production time and measure and record overall efficiency and losses to be able to remove them once they have been recognized.

Downtime loss: This is considered to be anything that stops production for some time such as machine failure, shortages of required materials, and changeovers.

Performance: The performance covers any factors that may cause your machinery not to operate at its maximum speed or capacity.

Quality: OEE will also consider any quality loss issues. This means that it will identify when a product does not meet the required standard and has to be changed.

As soon as these factors are taken into account, you will be left with a measurement of "Fully Productive Time". This is the time when machines will be operational and working to their full efficiency.

The main aim of OEE is to help maximize and increase a business's production time. Studies have been conducted which indicate that the average manufacturing rate of most plants is around 60%. A world-class overall equipment effectiveness measurement is considered to be anything above 85%.

OEE Systems That Drive Down Manufacturing Costs Using Existing Resources

With the economic climate still skirting around on the edge of recession , and more recent talk of a further drop, many manufacturing businesses are approaching crisis levels. In an effort to stay afloat , competition amongst rivals is becoming stronger, and the need to cut costs whilst maintaining quality , and using existing levels of resource, has never been stronger. The new OEE ( Overall Equipment Effectiveness ) software systems, play a significant role in optimizing manufacturing production efficiency using the same plant resource . This has fuelled significant interest from many manufacturers , and is rapidly being adopted as the tool of first choice to improve the cost v profit ratio . Companies that employ OEE systems in their most simple form are able to monitor how efficiently their plant is performing in terms of throughput and contribution to sales. But that is only scratching the surface in terms of what the real power is when it comes down to seeking and implemen

The New OEE Impact Andon Boards for Spare Manufacturing System

Image
Andon can be defined as" visual control" device that shows machine, process status or line. Utmost spare manufacturing systems need this device as it's veritably useful to reduce product waste in all situations. By using andon boards, a company can cover and insure productivity fluently. Manufacturing storehouse use this tool to see order status or precedences in an instant way indeed from further than 100 bases down. This device can also serve as early warning bias since audible admonitions or advising dispatches are installed in the device. In short, it can be said that this communication tool leads to a better collaboration of orders, precedences and corridor in a spare manufacturing system. This good collaboration eventually leads to a better client service .    The use of andon boards replaces the part of traditional communication tool in spare manufacturing systems . With this device, now a company does not need to use clip boards, white boards or emails to communic

System improvements are brought about by the new Design for OEE methodology.

  If your firm uses automation to increase productivity , as most businesses do, OEE is a crucial statistic for evaluating where improvement efforts should be directed. All three OEE components —Availability, Performance, and Quality—apply if most of your production stages involve manufacturing machinery.   The component results have averaged 90%, 86%, and 98.7%, respectively, for the firms I have tracked and following some improvement attempts. The OEE for this is 76.4%. OEE of 85% is typically used as a world-class benchmark by enterprises . Even this standard for excellence can be surpassed with a change in emphasis regarding where improvements are made.   Most Lean Six Sigma practitioners have seen the cost and quality advantages of DFSS in the New Product Introduction process. Design For Overall Equipment Effectiveness , or DFOEE, is something I would want to propose that is similar and equally as advantageous. I agree that the DFSS technique may be used for machine design, an
