通用航空运行信息服务系统研究

通航运行的核心是航空器四维航迹的规划与执行。本研究围绕通航四维航迹的规划、协商、调整和执行中的协同决策与航迹优化等难点与热点问题，开展通航运行信息服务系统的服务框架、理论方法与关键技术研究。针对我国通航运行特点，提出SWIM信息架构下的四维航迹协同决策模型，建立通航运行信息服务框架。针对通航四维航迹规划问题，重点突破基于DBSCAN和小波变换聚类算法的数据挖掘与信息融合关键技术；将四维航迹规划抽象为网格化空间拓扑下的路径搜索问题，提出采用贪心策略的规划算法模型和基于隐马尔可夫模型的路径选择策略；采用专家预测和历史数据分析方法研究价值评估函数，建立基于多属性决策方法的四维航迹量化评估模型。研发面向通航企业的采用SWIM框架和Web-GIS集成工具的信息服务验证系统，实现覆盖通航运行从拟定飞行计划到飞行后报告全过程的信息服务支持，为建立覆盖全国的通航运行信息服务系统奠定理论基础与关键技术支撑。

General aviation operation rely on 4-Dimensions Trajectory (4-DT) planning and execution. In order to deal with those difficult and hot problems in collaborative decision-making and 4-DT optimization in the process of planning, negotiation, adjustment and execution, this study will focus on framework, theory and technology of the information service system in general aviation operation. A 4-DT collaborative decision-making model in SWIM (System Wide Information Management) will be present to build a framework for the information service in general aviation operation in China. According to the problem of general aviation 4-DT planning, the study will provide the key technologies of data mining and fusion based on DBSCAN and WaveCluster algorithm. 4-DT planning can be considered as a routing problem in the 3-D grids. A trajectory planning model using the greedy algorithm and a route selection strategy based on hidden Markov model will be present. The value function is designed through the Delphi Method and history data analysis, and 4-DT quantitative evaluation model through the multiple attribute decision making method will be built. At last, a user-oriented general aviation operation service prototype system for operaters, based on SWIM (System Wide Information Management) framework and Web-GIS technology, will be developed to supply the service for general aviation over the whole process from pre-flight planning to post-flight reporting. The study will provide the theoretical foundation and key technical support for the establishment of a nationwide information service system for general aviation operating in future.
