随着航班起降架次的不断增长,许多大中型机场在高峰小时出现了不同程度的拥堵,机坪俨然成为继空域和跑道之后又一个制约机场容量、降低机场地面运行效率的瓶颈.通过问卷调查方法对机坪容量的影响因素进行统计分析,运用集成的DEMATEL-ISM方法对各因素的重要程度进行定量化计算.为得到科学合理、层次简明的解释结构模型,引入阈值入,将整体影响矩阵简化为邻接矩阵,进而确定影响因素之间的联系及层次关系,找出影响机坪容量的关键因素,最后结合中心度和原因度的计算结果对各影响因素的重要程度进行验证分析.机坪容量影响因素分析为机场规划设计、机场运行管理人员合理确定机坪容量、提高机坪使用效率提供科学决策的依据.
With the increasing number of flights taking off and landing, many large and medium-sized airports experienced different degrees of congestion at peak hour and the apron became the bottleneck that constrained the airport capacity and the airport ground operating efficiency after the airspace and runways. By questionnaire Methods The influencing factors of apron capacity were statistically analyzed, and the integrated DEMATEL-ISM method was used to quantify the importance of each factor.In order to obtain a scientific and rational explanation hierarchy model with simple structure and threshold, the overall influence matrix Simplified to the adjacency matrix, and then to determine the relationship between the factors and the relationship between levels to identify the key factors that affect the capacity of the apron, and finally the center of the degree and the degree of the results of the calculation of the importance of each factor to verify the analysis. Capacity analysis of factors for the airport planning and design, airport operators and managers to determine the appropriate capacity of the apron to improve the efficiency of the use of apron to provide scientific basis for decision-making.
