基于粗糙集理论的终端区飞机排序综合评判

针对日益增长的空中交通流量所带来的严重航班延误,提出了一种全新的终端区（TMA）飞机排序方法。在介绍粗糙集综合评判方法的评判过程基础上,建立了TMA飞机排序问题评判指标体系,进行了飞机排序综合评判过程的算例仿真。仿真结果表明,方法简单可行,能够客观得到各评判因素权重,并且与先到先服务（FCFS）排序方法比较,影响范围减少50%,累计延迟时间减少23%,说明方法排序结果优于FCFS排序结果。

Research on Comprehensive Evaluation for Aircraft Sequencing Problem in TMA According to RS Theory

Because of the airline delay caused by increasing air traffic,a new aircraft sequencing algorithm in TMA is put forward.According to evaluation process of RS comprehensive evaluation method introduced,evaluation index system of terminal area aircraft sequence problem is established,and the data analyses are completed finally.The simulation shows this simple and feasible method can impersonally achieve each evaluation index weight,and contrasted with FCFS,affected range is reduced by 50%,and total delay time is reduced by 23%.The result demonstrates that this method based on rough set theory is better than FCFS to solve above problem.
