| Tiivistelmä: | The problem of obtaining optimal integer solutions in shift scheduling environments is studied where a high degree of scheduling flexibility is desired. A new implicit integer linear programming formulation is presented for the inclusion of meal/rest-break flexibility. An experimental analysis using four different labor requirements patterns and ten shift-length combinations demonstrated that, when flexible break assignments were modeled, the implicit formulation was superior to traditional set covering formulation in execution time, in computer memory requirements, and in the ability to produce optimal integer solution to larger problems. |
