Social choice function with subordinate relations as one variable

The paper proposes a social choice function R = g(R₁ R₂, ?,R_n, U) with a binary relation U called a subordinate relation on the group decision-makers in addition to individual preference relations R_i(i = 1, 2, ?, n). Then the individual influence to the group decision-making is connected with a relation U so that the more the members are subordinate to a member, the more its preference is reflected to the social preference. Two functions are defined as examples of such functions with subordinate relations. Four conditions, a theorem and real-world type examples to group decision-making are presented
