"The second traditional approach of investment appraisal is the Return on Capital Employed which, like payback, has many different names( perhaps the most common is the Accounting Rate of Return) and a wide variety 0f different methods of computation."

第二种传统的投资评估法是使用资本收益法，跟付还法一样，它有许多不同的名字(也许最通用的名字是会计收益率)，和许多不同的计算方法

This method was applied to the dimensionality reduction of multidimensional time series via projection pursuit technique for fuzzy clustering. According to the results of the classification and the extraction of fuzzy rules through best value projection, three types of fuzzy membership function were generated using trapezoid distribution method. Then the sample's credit level was determined according to the fuzzy approximability in computation.
