In this multi-machine scheduling problem activities have to be assigned to one machine, while taking into account the delivery (or due) dates of the activities. The objective is to minimize the makespan. The machines are different. This machine scheduling problem is formulated as a MIP problem.
The project contains one page showing a Gantt chart that displays the assignment of the activities to the machines. The Gantt chart is updated whenever the solver finds a new solution. The page also contains a graph that displays the progress of the optimality gap during the optimization run.
Gantt chart, MIP gap, callback procedures, GMP, calendar.
