Une méthodologie pour modéliser et optimiser la mutualisation du transport ferroviaire urbain de marchandises et de passagers

Abstract : Urban freight transport is almost exclusively carried out by truck. Beyond the drawbacks caused in the city, this transport mode is nearly saturated. This study discusses an alternative way of transporting freight by using urban rail infrastructure. The first contribution deals with the identification and classification of all different sharing possibilities of mixing freight with passenger’s traffic using rail network. The second contribution is the definition of global freight/passenger transport problem, which is decomposed into several optimization interdependent sub-problems with different temporal decision horizon. In order to show the capacity of the global system to absorb an additional flow with different nature, the Freight Rail Transport Schedule Problem “FRTSP” is identified as the bottleneck of transportation system and is formalized with MIP model. As third contribution, this problem determines train and loading time for each demand to be assigned respecting several constraints while minimizing total waiting time. The fourth contribution deals with a discrete event simulation approach, which studies this alternative and validates several proposed decision algorithms. Finally, the fifth contribution consists in a dynamic approach based on a rolling horizon, which is proposed in order to update the initial plan. The updated plan allows to determine a new assignment regarding new demand such as the modifications from the previous plan are minimized
