Study on a Set Pair Cloud Decision Method
The paper uses cloud model and SPA,and proposes a natural language-based multi-attribute decision method: set pair cloud decision,for short SPCD.It includes mainly several parts as follows.First,the described rank cloud and the evaluated rank cloud respectively are presented to measure attribute rank and rank certainty degree.On the basis,cloud normalizing algorithm is presented to fuse several values of an attribute given by experts.Then,set pair evaluation algorithm is presented to describe by the numbers all attribute values from three angles: identic,opposite,uncertain,and its result is the systemic equation of every evaluation project feasibility,and then the most desirable alternative is selected according to their described chart with comparison and analysis.Both of Cloud model and SPA can express the relationship between randomness and fuzziness,so the SPCD method is more effective to measure linguistic assessment information.Finally,simplicity and feasibility of the method are showed with evaluation of energy development project.
