Research on Computer Preparation of Optimized Passenger Train Work Diagram

The design principle of computer preparation of the optimized system-wide through passenger train work diagram is regulated. Three basic algorithms for the passenger train work diagram solution are put (forward:) a) Based on the single-track meeting with additional time system; b) event forecasting system with time approach and segmentation to forecast the train dynamic trajectory and events; and c) the hierarchy (approach) method which is based on the passenger contour diagram to find the cycle solution, and approach the target value layer by layer. Through comparison, and analysis, the hierarchy approach method is selected to (prepare) the passenger train work diagram. The paper describes such key technologies as the train identification, route processing, interval inspection of trains in Beijing Junction, and graph processing. It puts forward the (programming) function of the design system.
