摘要: 针对管制中心系统,利用层次分析法评估其系统效能。分析影响管制中心效能的各类因素,建立适合我国军民航特点的管制中心系统效能指标体系和度量标准;利用专家提供的各个指标之间的相对重要性,构造判断矩阵确定其权重;最后利用概率乘法递归地求出各指标相对于系统效能的权重系数,管制中心系统效能值等于各指标权重与其所对应的隶属度乘积的线性加权值。仿真得出的评估值和专家的结论基本一致,表明了利用层次分析法评估管制中心系统效能的合理性。

Abstract: The performance of air traffic control system was evaluated by using Analytic Hierarchy Process (AHP). Firstly, the factors that can affect the performance of air traffic control system were analyzed and air traffic control system's performance guidelines and metrics suitable for the characteristics of China's military and civil aviation were established. Then the relative weight of these guidelines could be obtained by computing the judgment matrix that was constructed by experts. At last, the relative weight to the system performance could be got by recursively using probability multiplication methods. Finally the value of air traffic control system's performance equaled the liner weighted value of product between weights and their corresponding indicators of membership. According to the statistics conducted by the simulation, it is basically the same as the conclusions of experts, which shows it is reasonable to use AHP in the performance evaluation of air traffic control system.
