Rail Transport and Energy Consumption
This paper attempts to portray the present unstable situation of handling passengers and freight inside Iran as well as to represent a clear view of the rail transport features that have given this mode of transport a special place among the transport system. In this paper the rate of fuel consumption as a main pivotal item has been evaluated as well as the amount and cost of fuel economized th...
متن کاملSingle-Car Routing in Rail Freight Transport
Cars in rail freight service follow prescribed routes from their origin via intermediate shunting yards to their destination. The goal in designing such routes is to reduce the number of trains and their travel distances. Various real-world hard constraints make the problem difficult to formulate and also to solve. We present integer programming formulations for this car routing problem arising...

متن کاملSimulations of transport in one dimension
Advection-dispersion equation is solved in numerically by using combinations of differential quadrature method (DQM) and various time integration techniques covering some explicit or implicit single and multi step methods. Two different initial boundary value problems modeling conservative and nonconservative transports of some substance represented by initial data are chosen as test problems. ...
