Abstract
Integrated real-time dynamic routing(IRR) network provide dynamic
routing features multiple classes-of-service on an integrated transport network.
In a previous Journal paper it is shown that IRR network s allow reduced
network management costs since with real-time dynamic routing a number of network
operations are simplified or eliminated, leading to savings in operations costs and
expenses. In this paper, a new algorithm is described for the transport design of
IRR network which achieves near-optimal capacity engineering. In particular,
a Karmarkar Algorithm optimal solution to the linear programming flow model
achieves approximately a 5 to 8 percentage point reduction in network design cost
in comparison to the designs of pre-planned dynamic networks solved with
heuristic design techniques. The optimization techniques described in this and the
previous Journal paper attain significant capital cost reductions and network
performance improvements by properly modeling the more efficient operation of IRR
networks.
Keywords: Dynamic routing; transport network design; linear programming flow
