of the constraints in this project are ultimately left to the end user to decide. The
weight-window is shown in figure 6.6.
Figure 6.6: The weights window
View codes shows the various shift-abbreviations, their meaning, where the shift takes
place and what shifts it covers (night, noon, afternoon or evening, or a combination
of either). The user can add or delete definitions here. The codes are used when
importing shifts.
Set code file is for loading another code definition list than the one already loaded.
The format used for the codes file is .xls (Microsoft Excel).
Rolling Day Off enables the user to select whether the RDO-mechanism should be
enabled and for which weeks the RDO should include. Figure 6.8 shows the RDO
window. As of now, the mechanism works with six doctors as is the goal. Though a
more dynamic algorithm is preferable, time was of the essence when implementing
the algorithm.
Day starts at 8am specifies whether a day in the sense of shifts starts at 08.00 am or
at 00.00 am. Tradition sometimes dictates that the night shift of the 20 th physically
lies on the 21 st . The underlying function is to move imported night shifts from
day x to day x + 1, and when showing the schedule in the calendar-view, moving
them back.
Pressing either Generate-button, will result in a generated schedule, showing progress in
the status-bar and when the generation of the schedule is done, the value and violations
of the schedule. Figure 6.9 on page 40 shows the application window after a schedule
has been generated.
