Abstract:In the cooperative systems composed of multiple domain related ESs, ESs which can solve the same one problem A independently, are often organized as a cooperative group. Sometimes, each ES in the group all gives the same assertion to problem A, whereas the CF (Confidence Value) for the assertion is different. In this paper, in order to process this kind of inconsistency problem, we improve the strategies of approaching to the highest CF and adjacent influence, propose the strategies of approaching to the highest authority and interactive influence.Moreover,wealso propose three computaional methods about the maximum deviation of the united CF of the cooperative group which are method based on fuzzy entropy,the method based on norm and the method based on mean deviation value.These computational methods are based onthe measure about the degree of inconsistency of all CFs in the group.
