One of the obvious conditions for the applicability of economic and mathematical models is their adequate reflection of transport processes. The issue of adequacy should be decided separately for each specific model. However, in the case of modeling for the river fleet, we can talk about the existence of traditional approaches to building models that are outdated and lead to inadequacy of all such models. It is shown that the proposed models do not fully reflect the properties of the transport process, and, therefore, their use in practice can lead to significant errors in the planning of the fleet. The analysis of typical errors in the models construction for the fleet planning is given.
