Certain production output may be inaccurate or invalid for your Production Analysis. For example, if there is a planned shutdown for three days, there will be three near-zero production output values that you will not want to include in the production loss calculations. You may want to include this data in your production data for record purposes, but you may not want it to affect the calculations of the reliability losses. In this case, you can ignore individual production output datapoints from the analysis.
You can ignore any datapoints for any reason. Keep in mind, however, that the goal is to ignore datapoints that would inaccurately skew your Reliability Loss calculations. For instance, you may want to ignore datapoints associated with planned shutdowns because they represent planned, intentional losses. You would not, however, want to ignore datapoints associated with unplanned shutdowns, which represent unplanned, reliability losses due to equipment and location problems.
In the Production Data plot, select the datapoint that you want to exclude.
The Point Tooltip window appears.
Select Ignore.
The selected datapoint is excluded. GE Digital APM recalculates the losses on the Production Loss Regions pane, taking the ignored datapoints into account. The ignored datapoints are still plotted on the analysis, but are represented by a black dot.
Hint: You can also exclude a datapoint via the Production Data Editor window for a Production Analysis. To do so, in the row containing the production data that you want to exclude, select the check box in the Ignore cell of that row, and then select OK. The selected datapoint will be excluded.
Note: If you want to include the datapoint, you can select the excluded datapoint to open the Point Tooltip window, and then select Include.
