Analyze APQ Goal Deviation Chart
Explanation
Use this activity to determine the difference in
percentage between the defined A (availability), P (performance), Q (quality)
figures and calculated APQ goal values and their actual values using the APQ
Goal Deviation Chart view.
- In this chart the goal reference is defined as a
zero level, i.e., a negative difference indicates that the actual value is
below the set goal.
- You can hide/unhide one or more dotted lines as
per your requirements. By default, the APQ line is displayed while the other
lines are set hidden.
- Average lines and/or trend lines can be displayed
in the graph by selecting the relevant right mouse button option.
- Standard features such as Zoom and Search can
be used on the graph.
- You can view information for all events, OEE loss
events as well as registered goals by selecting the relevant right mouse
button option.
- The Start and Stop markers in the graph represent
the specified period of time that is to be analyzed. Note: In order to have the lines in the graph
cross these two markers, an extra dot (node) is included outside the specified
time period.
The figures for average lines or trend lines are
calculated with due consideration of the defined goal reference. If the lines
are below zero in the graph, the actual values are below the specified goal
values. At such instances, the average value in the graph cannot be compared to
the average value in the status section.
The lower section of the APQ
Analysis window is
common for all three views, with a filter section to the left and
a status section to the right.
(a) In the filter section you can choose the time
period to be analyzed and the interval between the dots (nodes) of each
line. You can also enter data when filtering, so as to, only include the parts
you want.
(b) In the status section you can view information
on the calculated average figures for A, P, Q, and APQ for the chosen time
period. Information on the quantity produced and the quantity scrapped
during this time period is also specified. Additional information on the
production key figures and production stop figures can be viewed in the
Extended OEE Analysis window.
Prerequisites
N/A
System Effects
The actual figures for A, P, Q, and APQ can be compared
with the specified goal values to determine the effectiveness of a production unit.

Procedure
- Find the required production unit from the Overall
Equipment Effectiveness navigator and expand it. A list of windows used for
analysis of the production unit will be shown. Click APQ Analysis.
The APQ Analysis window opens.
- Locate the chart view list in the upper right
corner of the window and select APQ Goal Deviation Chart. The
APQ Goal Deviation Chart window opens.
- Use the available filter options to specify the
time period that is to be analyzed in the graph, e.g., 30 Days.
- Use the available filter options to specify the
data you want shown in the graph, e.g., product qualities.
- Once all values to be filtered on are given (or
modified), click Refresh to update the graph.
- To the right of the window you will find several
attributes that are used in the graph. Click on the icon associated with the
attribute you want displayed or hidden in the graph.
- To include an average or trend line for an
area in the graph, right-click on a dot (node) in the line, and then
