Operation split and join

Use the Split operation function to split operations into two or more operations. The function is available by

• double clicking in the column “Split” in the operations list of the route editor
• selecting “Split operation” in the shortcut menu, when right clicking an operation in the Gantt chart.

Operations can be split by percent, hours or quantity.

Type	Before	After
Split using 50-50 distribution
Split using 30-70% distribution
Split using parallel
Join operations Operations can be joined by selecting the operations to be joined and then pressing the join button in the shortcut menu.

*Splitting multiple operations at once
To do this just select multiple operations before clicking split in the context menu
A tabbed panel will appear for each original operation. In these, the attributes of each new operation can be edited, just like when splitting only one operation.
An extra tabbed panel will appear called Collective. If you check the checkbox in that panel, you can edit the percent and resource for each split in each operation at the same time. This panel will unavailable if the original operations have no possible resources in common.

!Note that you can only join operations that have been previously split!

*If your ROB-EX Scheduler is integrated with an external ERP system, then check with your local system administrator how the integration is affected by carrying out an order split

Advanced splitting

Split by

• Fixed number: split the operation in a fixed number of steps
• Batch size: Selecting this option will split the operation in the defined batch sizes. If the current quantity is not a multiple of the batch size the remainder is placed on the last batch
• Mouse position: The operation will be split at the position the mouse was when the right click menu was brought up.
• At progress: Split the operation at the last progress time-stamp and assign the produced quantity to the first part and the remaining quantity to the last part. The first part will be set to status completed!
  Note: This is only available if the operation is started AND there is progress reported on the workload

Create initial split for completed

If the operation is started AND has progress there will be an initial split made matching the completed quantity before the split parameters are applied.

Split progress based on percent

• By checking the Split progress based on percent checkbox, progress will be distributed over the operations according to their size.
• By not checking the Split progress based on percent checkbox, progress will first be filling up the first operation then the second, etc.

More split options

Use original operations name

• By checking the Use original operations name, all new operations will have the same name as the original operation.
• By not checking the Use original operations name, all new operations will have the same name as the original operation plus an individual number.
• You can always edit the name yourself by clicking in the name cell for a new operation.

Hard link

When the Hard link option is checked, then all new operations after the split will be hard linked to each other.

Split order

When the Split order option is checked, then all operations of the order will be split. When enabled, then notice the additional tabs being added at the bottom – one tab for each operation of the order. This option is similar to select all operations in the order for splitting, before selecting the Split operation option

Important: all of the splitted operations are still assigned to the original order, so the result is not new orders.

Splitting hard linked operations

When splitting hard linked operations there are special cases where the behavior of the split will change. The reason for this is that the split is not allowed to add a hard linked cycle in the route.

There are two cases where this could happen:

• If we split an operation that have multiple incoming or outgoing hard linked constraints and we choose to split with the parallel option enabled.
• If we split an operation that have both incoming and outgoing hard linked constraints and we choose to split with the parallel option enabled.

These cases will be caught and changed from the normal behavior, where we copy all incoming and outgoing constraints to all split parts, to only have incoming constraints to the first split part and only outgoing constraints from the last split part.

Splitting operations with suboperations

The split of the suboperation will simply follow the primary operation (Do not select the suboperation).

If the suboperation is linked to a step, e.g. the setup step, and one of the split parts is set to not have any setuptime, a zero sized suboperation is added to the split part.

Viewing splits in the route editor

In the window “Edit route” the column “Split” shows if an operation splitted. The colors shows which operations original comes from the same operation
