提出了一种基于传递闭包法的进/离场航班分类方法。首先对模糊集合理论和传递闭包算法作了简要的介绍,然后在考虑4种不同因素的条件下建立了航班分类模型,并给出了各类航班单位时间延误成本的计算公式。最后以终端区航班排序模型为例,对该方法进行了仿真,并与传统航班延误成本分类方法进行了比较。仿真结果表明,该方法有助于减少航班延误损失,优化进/离场航班队列,提高空中交通管理效率。 A new method of flight classification based on transitive closure is proposed. Firstly, the fuzzy set theory and the transitive closure algorithm are briefly introduced. Then, the flight classification model is established under the consideration of four different factors, and the formula for calculating the unit time delay cost of various types of flights is given. Finally, taking the terminal flight scheduling model as an example, this method is simulated and compared with the traditional flight delay cost classification method. The simulation results show that this method can help to reduce the flight delay loss, optimize the queue of inbound / outbound flights and improve the efficiency of air traffic management.
