Method of case-based real-time decision deduction of track utilization in railway passenger stations

Real-time decision problem of track utilization in railway passenger stations is a type semi-structural problem and its deduction can provide theoretical basis for solving real-time decision problem with special conditions,which has very important practical meaning.Adopting matter element theory,this paper constructed case-based real-time decision model and divided real-time decision matter element into train matter element,plan and deduction ones.Then,it combined with the thinking process of dispatchers for solving real-time decision problem with special conditions,adopted superiority evaluation method and learning method based on double-space model,designed case-based real-time decision deduction algorithm and rule-self learning algorithm,and put forward methods of case-based real-time decision deduction of track utilization,to make real-time decision plans with special conditions.The instance results indicate that the model and algorithms can solve the real-time decision problem with special conditions effectively and the intelligence level of real-time decision of track utilization can also improve greatly.
