Splitting batches
The functionality enables you to divide a process or tank batch into two or more new batches. The existing flow constraints defined on the process step are considered. If splitting the batch results in a violation of one of the constraints, a confirmation message is displayed.
A batch has inflow and outflow segments. During these segments, there is product flow into and out of the batch.
Inflow and outflow must not occur simultaneously or at the same rate. Additionally, for an incomplete scheduled batch, the inflow quantity is smaller than the outflow quantity. When splitting, both the inflow and outflow is split in the same way as the new batches require inflow and outflow.
This image explains the process in which the splitting is calculated.
From the t-split splitting quantity, the time points t-in and t-out on which the segments are split, are calculated. If the inflow quantity is less than the splitting quantity, the end of the inflow is considered. The quantity and the time point can be calculated for other segment if one of the splitting time points is known.
If a duration (d) is specified, this is first converted into a point in time using the equation tout= start + d, and the method specified above is applied.
The point at which you split the batch must be in the inflow or outflow segment of the batch. The end time is calculated from the beginning of the original batch. The application ensures that the inflow and outflow are mutually consistent, and the duration must not be too long. The various values that you can specify are calculated from the batch duration. Therefore, leads to inaccuracies, as the duration is rounded off to whole minutes.
