Movement Planner

Standalone Movement Planner(SAMP),Real Time Movement Planner (RTMP) and Meet Plan Worksheet (MPW) Production development of GE Transportation Optimization Solutions Product Team in this role focuses two related products: Meet Plan Worksheet and Real Time Movement Planner. The Real Time Movement Planner (RTMP) adds automatic conflict resolution to the solution as well as optional automatic route setting. The dispatcher is always able to override the decisions made by the system but in this mode of operation, he/she is dispatching by exception with the vast majority of the conflicts resolved by the system. The Meet Plan Worksheet (MPW) is a real-time online planning tool that provides dispatchers the ability to view the expected time of arrival of trains at various points in the rail network, project where the trains will come into conflict, and assign the siding locations where the trains will meet or pass.
