Application of DTOPSIS and grey relational analysis in evaluating newly introduced flue -cured tobacco varieties
Introduced flue - cured tobacco varieties were evaluated by DTOPSIS and gray relational analysis. Results showed that significant difference in evaluation existed in two methods. Given the same weight, grey relational analysis shows no significant differences among variet ies, while DTOPSIS has different results. It implied that DTOPSIS is more appropriate, especially when a large number of testing varieties were needed to be classified.
