Determine when each of a set of flights should take off.
Each flight is described by
a desired/scheduled take off time, and
the time intervals at which it will use
various resources (take off runway,
flight control sectors, landing runway).
Each resource (runway or flight control sector) is described by how many aircraft can simultaneously use it.
The objective is to minimize the total ground delay suffered by all flights, subject to no resource being overutilized at any point in time.
Time is discretized into buckets.
The parameter tmbkt specifies the length of each bucket;
