Agenda
• Problem statement
• Goals
• Branch-and-Cut-and-Price for VRPTW
• Impact of the parameters
Problem Statement
• Project initiated by a main European
freight airport
• Set of planes (TW)
• Set of trucks (C
i
)
• Demand evolves…
Project goals (work in
progress)
• Model and solve the problem
– (Scheduling or) VRPTW
– Exact method (and/or heuristic: ant colonies)
• "Survey" of the exact methods for the VRPTW
– 30 last years of research: lots of "things"
– Selection of the methods, tricks and parameters:
impact
!
• Improvements?
Exact methods for the
VRPTW
