Fuzzy ISM Application for Designing the Logical Structure of the High-speed Railway Intelligent Dispatching System
Yang Liu, Ping Li, Sai Shao · 2023
The effective operation of intelligent dispatching system for high-speed railway (HSR) can reduce the heavy task pressure of dispatchers, thus improving the level of railway transportation organization. Since the railway intelligent dispatching system covers dispatching jobs such as driving, planning, locomotive, freight transport, passenger transport, motor train, construction and maintenance, it is necessary to fully consider their correlation when designing the logical structure of the railway intelligent dispatching system. In this paper, the main basic functions and database of railway intelligent dispatching system are extracted from Data Flow Diagram (DFD), and the logical structure of the system is clustered by using fuzzy Interpretive Structure Model (fuzzy ISM) method. After that, the basic functions are further divided, which can reduce the complexity of system design, the difficulty of system development and the running cost, and improve the system efficiency.
