Based on the comparison and analysis of the calculation methods of the capacity of the throat turnout at home and abroad, the paper presents the system structure and function design of the integrated system of the visualization of the throat flow capacity of the station. The application of graph theory and network optimization technology to the throat placement, The abstract model was constructed and the compound hierarchical decision-making model of the throat assignment occupying and arranging the network optimization and the throat working ability was established.This research used the above models, algorithms, computer information processing and graphics technology to visually simulate the throat operations and realized Computer simulation of core basic data collection, job optimization arrangement and the maximum achievable capacity of the search and optimization, and the results of a graphical output.Examples show that the results are reasonable and credible, can be used for the evaluation of the station’s throat ability test.
