According to the statistics of 1998～2003 in Yunnan,based on fuzzy similarity ordering analysis,this paper analyzed the relationship between S&T input and GDP growth.

Aiming at the tender evaluation of construction projects,fuzzy analogy preferred ratio was introduced and the tender evaluation model was established based on fuzzy analogy preferred ratio,which was then used in the assessment evaluation study.

According to the incompleteness and uncertainty of information of sewage treatment project in small town,the decision model of the sewage treatment project in small town is built based on fuzzy analogy preferred ratio.

Application of fuzzy similar priority comparison on predicting the bid of landscape engineering projects;

Considering the result of fuzzy similarity priority ratio, the studied area was divided into 3 climatic regions: the suitable .

The weather division was done in 23 counties in Yimeng Mountion Area by usingfuzzy similarity priority ratio.

Considering the result of fuzzy similarity priority ratio,the main re-gio ns fo r intro ductio n o f S lash pine(Pinus elliottii Engelm)in China was divided into 3 climatic regio.

In this paper,we use image processing and texture analysis method to caculate several parameters which describe the fabrics wash and wear characteristic and use fuzzy priority similiarity comparison method to decide the grade of fabrics wash and wear characteristic synthetically ,so as to avoiding the affect of traditional subjective method.

Fixing attention on preference sort,the math model is constructed to decide the best flight route of UAV by decision method of fuzzy semblable preference.
