Large-Scale Passenger Decision Support System Design And Implementation

Large-Scale Passenger Station Decision Support System is a subproject of "Research and Development of Large Terminal Simulation System-Research of Large Passenger Flow Organization Theory and Analysis" which is key subject of the Ministry of Railways. In this background, based on the actual characteristics and requirements of Beijing South Railway Station, finally, I use dynamic simulation of computer, case-based reasoning technology and decision support systems, to design the Large-Scale Passenger Station Decision Support System.In modern design, organization and management of terminal passenger traffic has become perfect gradually. But in the station, changes of location functional, changes of streamline, update of equipment, traffic control and other emergency situation will make the managers hardly to deal them. Especially, at the time of holiday, summer vacation and Spring Festival, if the problem is not promptly disposed of, the station maybe sink into mess and then it will affect the normal entry and exit of passengers. Therefore, it's necessary to establish the Large-Scale Passenger Station Decision Support System.In reality, there will be thousands of cases, so I use case-based reasoning as the key method to design the system. Case-based reasoning is based on memory, using past cases and experience to solve new problems. It can be seen as the problem to the experience from the case of analogical reasoning. In the case of the abstraction process, ignore some of the factors that affect the small, highlight the main issues, and ultimately get a structured data. Case-based reasoning is the core module of the decision support system. Through analysis, I established the system with case base, model base, knowledge base and database, and I designed the case-based model. The system is easy to use and is highly scalable.
