Research On The Case Based Reasoning Of The Airspace Management System

Airspace management systems is to monitor aircraft flying within the airspace of the principal tools and air traffic control personnel within the formulation space flight program based on the deployment. Research-based CBR support system of airspace management, air traffic control personnel can provide assistance for the existence of flying aircraft conflict decision-making information to improve flight safety and air traffic control aircraft, the intelligence level.CBR Case-Based-Reasoning) is a case-based reasoning to solve problems through the reuse of past experiences to solve current problems of the new intelligent reasoning. In expert systems, knowledge representations often determine what kind of reasoning by way of expert system reasoning. The system is case-based expert system, case library, and expert system inference engine is the core content, in this paper, a detailed description:(1) highlights examples of plane crash in the system of sources and the construction of case library collision. Including the plane crash involving the aircraft’s flight characteristics, weather conditions, flight crew status, on-board anti-collision system status.(2) to show the system’s reasoning and retrieval methods. Include searching index and self-learning mechanism. This paper introduces the index structure and self-organizing feature map (Self Organizing Map, SOM), described its implementation in the system algorithms and program structure diagram.After that, an aircraft collision avoidance system in determining the weights of symptoms, use of rough set dependency on the property to determine the importance of an attribute. Airspace management support system for building a common decision table, decision table content is under a specific ASMAS some historical examples of information, so with the case matching case in the objective to maintain consistency.Then, the paper case base in the quality of the data are analyzed, the data shows the need to learn to explain the data, learning, and proposes an approach to learn cleaning.Finally, airspace management assistance system to crash flight cases and data processing methods are introduced based on avoidance of conflict and deployment program decision-making system. Introduces the system requirements, functions, structure, database design and test, evaluation and improvement.
