Abstract
We consider a fundamental problem, called \emph{QoS-aware Multicommodity Flow},
for assessing robustness in transportation planning. It constitutes a
natural generalization of the weighted multicommodity flow problem, where
the demands and commodity values are elastic to the Quality-of-Service (QoS)
characteristics of the underlying network. The problem is also fundamental in
other domains beyond transportation planning. In this work, we provide an
extensive experimental study of two FPTAS for the QoS-aware Multicommodity
Flow Problem enhanced with several heuristics, and show the superiority of
a new heuristic we introduce here.
