Flight and passenger delay assignment optimization strategies
(2017-08-01)
Article
Open AccessThis paper compares different optimization strategies for the minimization of flight and passenger delays at two levels: pre-tactical, with on-ground delay at origin, and tactical, with airborne delay close to the destination ... -
Fluid flow queue models for fixed-mobile network evaluation
(Universitat Politècnica de Catalunya, 2019-07)
Master thesis
Open AccessA methodology for fast and accurate end-to-end KPI, like throughput and delay, estimation is proposed based on the service-centric traffic flow analysis and the fluid flow queuing model named CURSA-SQ. Mobile network ... -
