Yard performance model based on task flow modeling
First Claim
1. A method for managing railcar movement in a railyard based on the flow of railyard tasks, using a system including a computer that includes a processor, a memory device, and a database, the railyard including six subyards, said method comprising the steps of:
- inputting initial parameters to the computer;
simulating railyard task flow utilizing a yard performance model and the initial parameters; and
determining if a train schedule can be met based on the simulated yard task flow.

Abstract
A method for managing railcar movement in a railyard based on the flow of railyard tasks, using a system that includes a computer including a processor, a memory device, and a database. The railyard includes six subyards including a surge yard, a receiving yard, a receiving inspected (RI) yard, a classification yard, a departure yard and a departure inspected (DI) yard. The method uses initial parameters, input to the computer, to simulate railyard task flow utilizing a yard performance model. Based on the simulation, the method determines if a train schedule can be met.
