基于余弦决策法的中小机场通航点选择

Cosine Method for Choosing Destinations of Medium and Small Airports

机场的通航点是提高机场吞吐量以及收入的重要因素。通航点选择是一个多指标决策问题。确定指标的权重时,本文采用了信息熵确定法,再利用余弦公式,比较决策方案与理想方案的差异,建立通航点选择的优化模型。通过对无锡机场的案例分析,验证了余弦决策法的有效性,并为中小机场通航点的优化选择提供一种可操作的方法。

Destinations of airports are very important for increasing throughout and income. Choosing destination is a decision making with multi - attributes. This paper used the entropy method to calculate the attributes＇ weights. Then the difference between a decision plan and the ideal plan was compared by a cosine decision mode. With the example of Wuxi airport, the validity of cosine method was verified. It also provided a practical way to choosing destinations.
