You can see the OEE graph in Shift View by clicking on the "OEE" tab (by default the "Speed" graph is displayed):
This graph displays the three components of OEE and OEE value for every hour of the shift.
Elements on the graph
- Green line (availability). Availability represents the percentage of planned time that a station (production line or workstation) is actually working or producing. Availability = Operating time / Planned time, in Shift View colors Availability = (green + yellow) / (shift time - planned stops).
- Yellow line (performance). Performance represents the actual running speed of the equipment against its specified running speed. Performance over 100% can mean that measuring of production is not set up correctly or targets (ideal cycle times) are set too low. Performance = good production / (good production + speed loss), in Shift View colors Performance = green / (green + yellow).
- Orange line (quality). Quality indicates the amount of products meeting the quality requirements (good products) out of all products produced. Quality = good products / (good products + scrap), in Shift View scrap is visualised using orange product circles.
- White bars (OEE %). OEE = quality x availability x performance.
