View OEE Overview

Explanation

Use this activity to obtain an overview of all your production units. In the OEE Overview window you can view APQ values for the last 30 days, observe if the trends are positive or negative, and view the current status of a production unit. You can also configure the data you want in this window as per your requirements. For instance, you can include or exclude a production unit from the overview and/or determine if trends are to be calculated [or not].

The OEE Overview window is divided into two sections. In the upper section of the window, a table with percentage values for A (availability), P (performance), and Q (quality), as well as the calculated APQ value for each production unit is available. Calculated short and long term trend values can also be viewed in this table.

• APQ values are calculated for the past 30 days using goal rates and internal events.
• The actual APQ values will be displayed with a Red background if the values are below the set goal.
• The actual APQ values will be displayed with a normal background if the values exceed the set goal.
• The short trend of APQ values is calculated by comparing the latest week to the past four weeks.
• The long trend of APQ values is calculated by comparing the last 30 days to the past 90 days.
• Trend values will be displayed with a Red background if the calculated values are minus five percent and more.
• Trend values will be displayed with a Yellow background if the calculated values are between zero and minus five percent.
• Trend values will be displayed with a Green background if the calculated values are positive.

In the lower section of the window, a production rate graph is displayed for each production unit. This graph can be used to identify when, during its operational life cycle, the production unit was in operation or stopped. The current status of the production unit is shown in the header of the graph. You can also view information on the number of stops and average production rate of a production unit in the graph. In addition to this, it is possible to obtain a more detailed view of a production unit by selecting the given link (Details).

Prerequisites

The production unit must exist in the Selected Production Units list in the Configure APQ Overview dialog box.

System Effects

APQ figures and trends together with the production rates can be analyzed for follow up of a production unit.

Procedure

1. To view OEE overview figures for the production units, click on the Overall Equipment Effectiveness folder name in the navigator. The OEE Overview window opens.
2. If you are performing this activity for the first time, the Configure APQ Overview dialog box will open automatically.
   Note: Henceforth, if needed, the Configure APQ Overview dialog box must be opened manually. To do this, right-click on the lower section of the window, and then click Configuration.
3. In this dialog box, choose the production units you want displayed in the OEE Overview window by selecting a value from the Available Production Units list and adding it to the Selected Production Units list.
4. Select the Calculate APQ Trend check box if trend figures are to to be calculated and displayed in the upper section of the window.
5. If you want to automatically refresh data in the OEE Overview window, enter a value in the Automatic Refresh Timer (Minutes) field. This indicates the time (in minutes) this action is to take place.
6. Click OK to close the dialog box.
7. The table in the upper part of the window contains data for the APQ figures both separated and calculated as a whole. If trends are activated, the data for short and long trends will also be displayed here.
8. If you want a more detailed view of the APQ analysis for a particular production unit, select the appropriate row and click Go to Analysis. This will open the APQ Analysis window with information for the chosen production unit.
9. To view registered goal values for a production unit, select the appropriate row and click Show Goals. This will open the Define Goals window with goal information of the chosen production unit.
10. Locate the available list to the right in the window and select the number of days to be included in the Rate graphs found in the lower section of the window.
11. In the Rate graphs you can view information on certain status figures, i.e., Stops and Average Production Rate.
12. Click Details (in the lower right section) to view more detailed information of a particular production unit.
