The questions of social sectors management are currently relevant. One of the problems is the almost complete absence of any mechanism for prices and tariffs managing, as well as enterprises evaluating in such areas as housing and communal services, public transport and public health service in order to determine the optimal “producer-consumer” pair. Within the framework of the conducted studies, it was revealed that the TOPSIS method adapted by the authors is suitable for this mechanism implementation; however, at the moment, within its framework, the procedure for the experts’ competence assessing has not been implemented. The possibility of mechanism developing for this procedure implementing based on the Delphi methods, Kemeny median and hierarchy analysis is being considered. It is advisable to use the proposed method for experts assessing not only in social sectors, but also in the assessments conducting process in any areas that require the experts’ involvement with different competence levels.
