SAW與標準化對稱變動率法應用於觀光發展指標構建之比較

This study is conducted to compare the Simple Additive Weight (SAW) and the Normalized Compatible Fluctuation Ratio (NCFR) method of measurement and their effect on the Tourism Development Index. The SAW method multiplies all indicator variables and their relative weight and then add the sum total to achieve the Tourism Development Index. This method is also considered as a linear combination by building up the total indictors. On the other hand, the NCFR method sets a certain year as the basis for comparison, then analyzes the changes by the ratio of fluctuation to the set year. In comparing these two methods, the major differences are: (1) the SAW shows a greater significance of changes; whereas the NCFR remains more stable and shows less of an overall fluctuation, (2) the SAW is much easier when it come to data input as compared to the NCFR method, (3) In analyzing the result graph, it is observed that although they both had similarincrement of movement, the SAW tends to increase at a much more rapid pace verses the NCFR graph which slopes at a slower pace. As a result of this comparison study between these two methods, it is recommended that the NCFR is better than the SAW method when in comes to long term comparison of the Tourism Development Index.
