Time-Line vs Connection Flight Networks For large-scale problems, time-line network has fewer ground arcs than connection arcs in the connection network Further reduction in network size possible through node consolidation Connection network allows more complex relations among flights Allows a flight to connect with onby a subset of later flights 2/212021 Barnhart 1.206J/16.77J/ESD. 15J2/21/2021 Barnhart 1.206J/16.77J/ESD.215J 12 Time-Line vs. Connection Flight Networks • For large-scale problems, time-line network has fewer ground arcs than connection arcs in the connection network – Further reduction in network size possible through “node consolidation” • Connection network allows more complex relations among flights – Allows a flight to connect with only a subset of later flights
