我是这样进行定义的：将城市之间的欧式距离和城市之间的好友数量都作为一个函数进行权重分析，然后根据权重值在两市之间绘制标线。

I defined weights for each pair of cities as a function of the Euclidean distance between them and the number of friends between them.

然后，运用层次分析法和EXCEL工具对数据进行整理分析，得出房地产多项目九大冲突因素的冲突度权重和排序，并绘制成图表；

Then it also makes use of Analytic Hierarchy Process and EXCEL tools in the analysis of these data, the weight of each index is calculated. So we can make a chart of it.
