中文摘要：

为了及时探测潜在冲突,保证调度的实施,在先到先服务（FCFS）及固定航路航迹预测条件下,对相关航空器进行冲突的探测,通过合理调度解脱冲突.文中提出最长公共子序列（LCS）思想的初步探测及基于4D航迹的再次探测方法,提高探测效率,以数据统计方法挖掘解脱路径用以冲突的解脱,以浦东机场进场航班实现仿真,验证冲突探测及调度的有效性.

英文摘要：

Under the condition of FCFS principle and track prediction on fixed route,detecting conflict for the related aircraft and make conflict free by reasonable scheduling.In this paper,the preliminary detection through the LCS（longest common subsequence）and again detection based on 4Dtrack are put forward to improve the efficiency of detection and using alternative path based on DM to eliminate the conflict.Puding airport fligts are choser to realize the simulation to verify the effectiveness of conflict detection and scheduling.
