Many publications describe problems in businesses and project management that are caused by communication. Team communication is a very complicated process full of soft aspects. One of basic problems represents a choice of an appropriate communication route kind useful for messages transmission between the team members as sources and recipients. It is a complex issue because of necessity to evaluate individual communication routes from many different perspectives. Therefore the suitable communication route of team members can be selected by a multicriterial mathematical model. Since communication can be understood as a distribution of messages, the appropriate model form can be based on the distribution model. The proposed model is derived from the three-dimensional transportation problem. The article discusses the possibility of this approach on the case study of communication modelling in the field of agriculture. Specifically, it is constructed and solved a model of communication problem for small team of agriculture equipment dealers.
