摘要
空中交通系统是复杂的非线性系统,时间序列是研究空中交通系统的有效措施。为了定量分析空中交通的复杂性,首先阐述Lempel-Ziv算法复杂度及其修正复杂度;然后采集三亚01号、02号、04号扇区连续28 d的实际运行数据,构建了空中交通流时间序列;计算了3个扇区交通流时间序列的算法复杂度,并对相关参数的影响进行了分析。计算结果表明,修正的算法复杂度适用于长度较短的时间序列,可用于量化测度空中交通流复杂性;符号化方法、序列长度、时间尺度等对算法复杂度有较大影响。
Air traffic system is a complex nonlinear system.Time series is an effective way to study air traffic system.In order to quantitatively analyze the complexity of air traffic,firstly,the complexity of Lempel-Ziv algorithm and its modified complexity are expounded.Then the actual traffic flow data of Sanya No.01,No.02 and No.04 sector were collected for 28 days.The time series of air traffic flow was constructed for each sector,and the algorithm complexity of these time series were calculated.And the influence of the parameters is analyzed.The calculation results show that the complexity of the modified algorithm is suitable for short-length time series,and it can be used to measure the complexity of the air traffic flow.The symbolic method,length of time series and time scales have great influence on the algorithm complexity.
