| Abstract: | Based on the existing qualitative mathematical calculations in relevant reference,we introduced the definition of the qualitative relations,investigated its basic properties and defined some operators over the set of qualitative relations,such as union,intersection,difference,and composition operators.Finally,we gave three basis of qualitative synthetic evaluation,and established measures of qualitative synthetic evaluation controlled by principal factor.At the same time,we applied the such measures to practice issue. |
