      Résumé : A class of extensions of an order on a set to an order on its non-empty multisets is characterised by three properties : Monotonicity, Equivalence and Independence. This class is defined by particular weighted sum representations. An additional property selects the Borda Score as a special case. The general class characterised have been used in practice in planning responses to domestic violence, particularly between intimate partners, and is recommended for this purpose by the Centre for Disease Control in Atlanta. It is also used in the construction of the Global Peace Index and has been recommended for use in measuring prison violence and regulation of violence in TV, digital games and for racism, hate crimes and other violent crimes.

      Résumé : In this paper we propose an in-depth analysis of a method, called the flow network method, which associates with any network a complete and quasi-transitive binary relation on its vertices. Such a method, originally proposed by Gvozdik (1987), is based on the concept of maximum flow. Given a competition involving two or more teams, the flow network method can be used to build a relation on the set of teams which establishes, for every ordered pair of teams, if the first one did at least as good as the second one in the competition. Such a relation naturally induces procedures for ranking teams and selecting the best k teams of a competition. Those procedures are proved to satisfy many desirable properties. Further, by means of the flow network method, we define a multiwinner voting system where individuals are allowed to express their preferences through any binary relation on the set of alternatives. That system is proved to be decisive, anonymous, neutral, homogeneous, unanimous, monotonic and immune to the reversal bias as well as to coincide with the multiwinner Borda count for preference profiles made up by linear orders. The theory here developed also allows to get an interesting characterization of complete and quasi-transitive relations.
