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:

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.
