The Approach to Weight Determination and Its Application in Measurement of Similarity Between Aircraft
Yang Wei-don · Aircraft Design · 2014
Due to development civil aircraft need learn from experience of similar other aircrafts, it's necessary to measure similiarity of aircraft with all kinds of parameters whose importance are different. For difference among parameters is large, it's significant to calculate quantificationally weight of property and sort property by importance. In the paper, the subjective weight distribution method with binary comparison has been discussed, which determines weights by experience of experts. Thus, based information entropy, objective weights and its calculation step are developed. At last, linear combination the subjective weight with objective weight form final weights. Taken current regional aircrafts as an example, the algorith behave well.
