The optimal planning of shipments with optimal traffic routing and train service provision subject to capacity limits is a major problem in rail transport. These services are the subject of the Train Formation Plan (TFP) problem, which concerns choosing how to rearrange and redistribute cars at different stations or yards. Another key issue is how to choose the right routes for trains from among the variety of paths on which they can travel between two points, which is the subject of the Traffic Routing (TR) problem. Integrating these two problems can provide better train formation and routing results. Other important issues in this area include the capacity of rail yards and the possibility of uncertainty in decision parameters like demand, which needs to be considered to have a realistic model. This article presents an integrated TFP-TR model with yard capacity constraints and demand uncertainty. The problem was formulated as a non-linear model and then the robust formulation of the model was developed using Bertsimas and Sim’s method. The objective was defined as the minimization of the cost. The solution approach was validated by applying the model to an example designed according to Chinese rail transportation network.
