Re: [rules-users] Newbie question. Possibilities for optimizing Employee Schedules

I have an application that requires optimizing an Employee schedule.
One of
the criteria is that the schedule must remain as static as possible. In
other words, when conditions change the system must make the minimum number
of adjustments to the schedule to accomodate the new conditions. We would
not want the entire schedule to be shuffled just because one person is off
sick.
Is this a criteria that can be easily handled with Drools Planner?
Yes
Give each entity an extra property: the original value of the planning
variable property.
For example:
class ShiftAssignment {
Shift shift;
Employee originalEmployee; // Just a normal problem fact
Employee employee; // Planning variable
}
then add a rule which adds a cost for every entity that moved
when
ShiftAssignment( originalEmployee != employee, $employee : employee)
then
// add soft constraint for -(employee.getMoveCost()).
You can make the move cost depend on all sort of factors.
