[rules-users] Long pattern for Nurse Rostering
I'm trying to create a rule for a 15 day pattern. When the patterns uses the
same shift for all 15 days, I do this:
rule "unWanted15DayPattern"
when
$pattern : U15DayPattern(
$numberOfDays : numberOfDays,
$shiftType : shiftType
)
ShiftAssignment(
shiftType == $shiftType,
$employee : employee,
$firstDayIndex : shiftDateDayIndex
)
ShiftDate( $firstDayIndex == dayIndex, dayIndex % 15 == 0)
//Check for different employee working that shift in the next N days
$shiftAssignment : ShiftAssignment(
shiftType == $shiftType,
employee != $employee,
shiftDateDayIndex > $firstDayIndex,
shiftDateDayIndex < $firstDayIndex + 15
)
then
insertLogical(new IntConstraintOccurrence("unWanted15DayPattern",
ConstraintType.NEGATIVE_SOFT,
$pattern.getWeight(),
$firstDayIndex));
end
But I'm having a hard time figuring out how to do it with different
shiftTypes for each day, because it means having to use a loop.
Not sure if that makes sense, but it anyone has used a long pattern that
stores items in a list/array I'd love to hear how they did it.
