Planned shifts

Bug

In the final presentation of our project a bug was found, possibly regarding this implementation. One other constraint could also be the source of this bug. More details can be found in this open issue.

Implemented using Google's OR Tools

src/cp/constraints/planned_shifts.py

variable_key = EmployeeDayShiftVariable.get_key(employee, day, shift)
if variable_key in variables:
    model.add(variables[variable_key] == 1)

For each planned shift we force the model to set the corresponding variable to 1, which assigns the shift.
