Fig. 4 - 13 OLE / OEE summary
This page contains two bar charts with legends, in which the OLE/OEE values are summarized:4
– Display OLE/OEE
– Display of achieved availability during the evaluation period
– Display of achieved performance during the evaluation period
– Display of achieved quality during the evaluation period
– Display of OLE during the evaluation period
This diagram can be shown by hours, days or weeks. 4
– Display Factor
Percentage display of OEE value for each machine in the line, during the evaluation period
This diagram can be shown by OEE, availability or performance. 4

The OLE/OEE values are also shown on further SMA pages: 4
– Machine Navigator
Shows the OLE/OEE values for the evaluation period currently selected on this page. The OEE
value is displayed for the selected machine.
– Factory Website - Overview Tab
Shows the OLE value for the current day.
NOTE
The following restrictions apply, if no boards are placed at the last station in the production line:
Overall Line Efficiency (OLE) diagram: Values for OLE, performance and availability will not be
shown correctly.
Overall Equipment Efficiency (OEE) by Station diagram: station data is not shown correctly for
stations which do not place boards. 4
Calculating OLE/OEE
– Availability
Availability = (Total Time - Downtime) / Total Time 4
Total time is defined as follows: 4
– Total Time= ALL - UNKNOWN
– Downtime = UNSCHEDULED DOWNTIME + SCHEDULED DOWNTIME
These values are SIPLACE Explorer results measured for the machines in the production line.4
– Performance
Performance = Rate Efficiency x Operational Efficiency 4
Performance is defined with Operational Efficiency and Rate Efficiency. 4
– Operational Efficiency
Operational Efficiency = Productive / Operational Uptime 4
Operational Efficiency is defined as follows: 4
– Productive = PRODUKTIVE
– Operational Uptime = PRODUKTIVE + STANDBY
– Rate Efficiency
Rate Efficiency = Sum (Line Takt) / Sum (Actual Line Takt) 4
These values are SIPLACE Explorer results measured for the machines in the production
line. 4

If the calculated result > 100%, SIPLACE Explorer shows only 100%. This happens, if the line
takt value was specified unrealistically high. 4
–Quality
Quality factor: this value can be defined in SIPLACE Explorer or can be imported from an xml
file. 4
–OEE
OEE = Availability x Performance x Quality factor 4
If the calculated result > 90%, you should check the line takt value. 4
The following procedures can be performed on this page and are described in this SMA
User Guide:

4.1.13 OEE Analysis
This page shows a summary of the OEE values. 4
These values can be used to generate an analysis about operation efficiency on an equipment
level. You can also manually define target values. 4
– Overall Equipment Efficiency (OEE)
This value shows the efficiency on an equipment level
