Let us build a model simulating how a maintenance center services wind turbines. There are 25 turbines, placed randomly in continuous space, that require maintenance.
There are two types of maintenance activities:
Wind turbines are serviced by one maintenance center. Center
has a fleet of 2 helicopters
and 5 trucks.
Optionally you can consider activity-based costing, adding costs per crew, adding part replacement logic with parts of different costs, etc
