Determining consensus with dependencies of set attributes using symmetric difference

In this paper the author considers some problems related to attribute dependencies in consensus determining. These problems concern the dependencies of attributes representing the content of conflicts, which cause that one may not treat the attributes independently in consensus determining. It is assumed that attribute values are represented by sets. In this paper the author presents conditions guaranteeing determining a correct consensus despite treating the attributes independently. Next, the algorithm for calculating the proper consensus in the cases when these limitations are not met is presented. Finally, the differences between proper consensus and consensus proposals calculated with treating attributes independently are considered.
