Process batches distribution

The Distribute Process Batches functionality is similar to Schedule Process Batches. These functions enables you to schedule process batches. Distribute Process Batches can also split the process batches simultaneously as the batch is scheduled. The difference between the two functions is distinct when a batch is large to fit into the available time slot. Schedule Process Batches simply shifts the whole batch to the next available time slot. The Distribute Process Batches function splits the part of the batch that fits in the available time slot and shifts the remaining part to the next available time slot. In determining whether to split the batch, the parameters such as time periods, downtime, locked or unselected batches are considered. Distribute Process Batches works effectively for batches with a process flow method defined by an outflow rate than for batches with a fixed duration.

You can view the required information on these tabs in the Distribute Process Batches window:

• General

  The generic information for distributing process batches including restrictions and join options.

• Split options

  Information related to splitting the process batches.

• Join options

  Information related to joining the process batches.

When distributing a process batch around an unavailable resource, you can link the split batches, in these consequences:

• The planning board displays a visual link.
• The changeover or setup time is not defined between the linked batches. You can override this configuration using the user-defined setup or user-defined changeover status attributes.
• Re-allocating one batch in the planning board affects all the linked batches.
• When further splitting the linked batches, you can retain the sub-parts linked using the link split batches option.
• When joining the selected batches (in which some are linked batches) you can select to join linked batches only using the linked only option.
• The split link can be displayed in the overview window.
• The split link can be imported and exported using these interfaces:
  • Process batch interface
  • Tank batch interface
• Other batches can be defined between linked split batches. The setup and changeover between the linked split batch and the non-linked split batch follow the standard setup and changeover calculations.
• The linked split batch setup and changeover calculation work with the same logic as transition rules.
• The solver considers linked split batches in account.

You can select these round-off types on the Split options tab:

• discrete product unit: The split batches are rounded off to the nearest discrete quantity.
• min/inc quantity: The split batches are rounded off to the nearest quantity that adheres to the minimum or increment quantity constraints of the process steps.
• none: The round off is not applicable for the split batches.
