End of day volume prediction

The system can predict End Of Day (EOD) volume for a meter based on hourly measured and estimated data. The system can then predict measuring station and line segment balances based on this prediction. Predictions are available for meters only.

Note: Prediction is enabled/disabled per meter.

The prediction is:

• Updated when new hourly data enters the system.

• Replaced by daily telemetered data.

• Replaced by aggregations if aggregation is enabled.

• Updated to an estimate if the daily telemetry data does not arrive by the start of the next gas day. (This creates a problematic context indicating that the daily telemetered data did not arrive).

  Notes: The system can also store a your EOD prediction entries.

  The prediction does not produce a problematic context unless the prediction was updated to an estimate.

The prediction is the sum of the following:

• Actual volumes from the top of the gas day to the present (including any estimates).

• Estimated volumes from the present to the end of the gas day.

  

  Note: The estimation method is the method selected for the meter.

The estimation method is one of the following:

• Last good value.

• Average of last N hours of actual values, where N is between 1 and 48.

• User-entered default value.

• Lagged Alternate value.

  Note: Custom estimation methods may have been added to your system.
