The weight of each evaluation index is determined with the methods of Delphi and expert consultation again. A group of students' oral English is subsequently evaluated by using AHP (Analytic Hierarchy Process) based on oral English evaluation index system and the weights we set up in this thesis.展开更多

In 2004 China became the world's second largest oil consumer and imported 122.7 million tons of crude oil, which accounted for 41.9% of China's crude oil consumption. International oil investment becomes an important channel for China to obtain oil resource. The cluster analysis in the target countries of China's international oil investment is studied here. An investment environment model incorporating 9 factors is established firstly, the order of these factors is ranked by their importance. Then the weight of such factors is determined by Analytic Hierarchy Process (AHP) and these countries are classified into 3 categories using cluster analysis. The results provide an important decision-making tool for China's international oil investment.展开更多
