OEE figure
OEE (Overall Equipment Effectiveness) refers to the actual usage rate of machines. Machines are purchased to produce, preferably without malfunctions or stoppages, at maximum speed and without loss of quality. To assess to what degree machines meet those requirements, the OEE method is very suitable. Objective offers various functions to track the OEE of the production process, both in real-time and historically. OEE is comprised of planned and unplanned losses in three categories, namely:
- Availability
- Productivity
- Quality
The total duration = the total available time (for example: a month, a week, a day, an 8 hour shift,...).
OEE is not only important to discover possible optimizations, but also to prepare realistic production planning. If you base the planning on the nominal production capacity of the machines, you often get a different result during the actual run. Objective allows you to work with a 'target efficiency' based on practical experience with all the production equipment. This allows for realistic production planning so that the actual production is very close to the planning.
In the following paragraphs, the composition of the OEE figures within Objective is described.
The general OEE % figure is a multiplication of:
- Availability %
- Productivity %
- Quality %
