Process cell optimization with online assignment of a unit

Introduction
When optimizing a process cell with online assignment, the unit recipe is assigned to the unit
at the last possible moment. If the unit is not assigned when the batch is running, the "online
assignment" function becomes active.
"Online assignment" provides the following four options (strategies) for optimizing the utilization
of units:
● Preferred unit: If no other assignment is made before creating a batch, the unit specified
as preferred is used for the batch execution.
● The longest out of use: The unit that has not been used for the longest time is selected.
● Operator selection: The allocation of the unit can be performed manually in an operator
dialog.
● Process parameter: The variable selected in the process parameter field decides the unit
to be used.
