Objectives

The first objective is to minimize the following function:

\[  \Variable{NumVehiclesUsed} = \sum _{v \in \text {VEHICLES}} \Variable{UseVehicle[v]}  \]

The second objective is to minimize the following function:

\[  \Variable{Makespan} = \max _{v \in \text {VEHICLES}} \Variable{TimeUsed[v]}  \]
