element Shift

Documentation

A fixed shift that can not be unassigned or altered. Optionally, a series of Tasks assigned to the employee, of Skills covered in the given time periods or scheduled breaks can be given. If this is not the case (or only for parts of the shift), the solver can determine appropriate Task or Skill assignments by itself. Shifts can also be set before the actual scheduling period. These shifts will not be changed or extended in any way providing a history of past shifts relevant for sequence or count constraints.

Properties

This component is not nillable.

Model

<Shift
  extend = xs:string
  ID = ID>
(Day, StartTime?, EndTime?, (Task | Skill | Break)* )
</Shift>

extend

If set to "None" the given shift is treated as complete and the solver should not extend it in any way (this means that a free time period must be directly before and after the assigned shift). A value of "Start", "End" or "Both" means that the solver can extend the shift in one or both directions, respectively, by adding additional time slots of work or assigning additional tasks at either end. Default: None.
