If you don’t measure it how can you hope to manage it!
No matter what type of process or manufacturing operation you are involved in and regardless of company size you are likely to be under constant pressure to improve performance and quality and increase equipment availability.
Targeting any one of these three key areas for improvement can seem like a major task, and making an improvement to one area can have a detrimental effect on another (for example, improving performance (ie. speed) could result in more rejects being produced); addressing all three areas together may seem completely unattainable. However, if these areas can be considered simultaneously, significant improvements can be made throughout the production process - output can be increased and production cost reductions can be achieved.
GAIN4 Efficiency uses the industry standard OEE (Overall Equipment Effectiveness) measure to provide a solution. OEE is a simple but clever calculation which focuses on individual items of process or manufacturing equipment at a finite level and allows their ‘effectiveness’ to be measured individually or in groups (i.e. with other equipment items). The OEE calculation is based on the ratio of the three key production parameters, availability, performance, and quality, with time (e.g. planned shift time/s) being used as the baseline measurement.
What is OEE and how is it calculated:
where...
Availability % = actual running time / planned production time
Performance% = pieces produced / the theoretical production rate
Quality % = good pieces / total pieces made
