Analyze APQ Loss Events
Explanation
Use this activity to view/analyze the events that
caused an A (availability), P (performance), Q (quality), or APQ cost within
your production unit. This event information can be viewed in the
OEE
Event Loss Overview window.
The OEE Event Loss Overview window
consists of four tab window: Availability, Performance, Quality, and APQ. The
events used in an APQ calculation will be displayed in each tab window as
follows:
- The Availability tab can be used to
view information on the events that caused losses in availability.
- The Performance tab can be used to
view information on the events that caused losses in performance.
- The Quality tab can be used to view
information on the events that caused losses in quality.
- The APQ tab can be used to view
information on all events, i.e., events that caused losses in A, P, and Q
figures.
In each tab window the events are grouped so as to make
easy the task of viewing/searching items. By default, the
Availability
tab is grouped according to the object ID and loss cause used. The
Performance tab
is grouped according to the product and quality used. The
Quality tab is grouped according to the
object ID, while the
APQ tab is grouped according to the object ID and loss cause used. For
each grouping in the list additional information is given, such as the number of
items (events) included in the group.
In each tab window, event records can be sorted by
revenue loss or filtered in several ways on the column level. If needed, you can
get a more detailed view of an event by selecting the relevant right mouse
button option. There is also an option allowing you to export
event records to another application, such as, MS Excel.
The lower part of the OEE Event Loss Overview
window contains the available filter options. In this section, you can specify
the time period for analysis as well as the data you want included in the
analysis.
