A multiobjective combinatorial optimization (MOCO) formulation for the following location–routing problem in healthcare management is given: For a mobile healthcare facility, a closed tour with stops selected from a given set of population nodes has to be found. Tours are evaluated according to three criteria: (i) an economic efficiency criterion related to the tour length, (ii) the criterion of average distances to the nearest tour stops corresponding to
