Mathematical apparatus for calculating the road transport operation volume, existing in the modern theory, corresponds to the only technology of the transport processfunctioning of the pendulum route with reverse unloaded mileage. However, modern specifics of freight motor transport enterprises functioning today is, as a rule, a frequent change of the clientele, types of freights and their volumes, distances of transportations, quantity and type of the rolling stock, average sizes of the technical and operational indicators, road congestion, number of drivers, condition of technological infrastructure and material and technical service opportunities. In this regard, studies have been carried out and the results aimed at making informed management decisions and accurate calculation of the planned need for vehicles have been presented. In the course of the research the methods of linear programming; professionallogical approach using the apparatus of mathematical modeling, including algorithm and software implementation of models were used. The analysis of the results of the previously developed methods and models application in the practice of planning the freight motor transport enterprises operation is carried out. It is revealed that the previously developed mathematical models are not implemented as there are significant discrepancy between the planned values and the results of motor transport enterprises work.

Optimal configuration of a regional transport and logistics system should be chosen from the standpoint of the goal of regional development, the environmental component of decision-making, and according to the criteria that determine the advantages and disadvantages of a particular mode of transport. The article outlines the main approaches to appreciation of the comparative advantages of certain modes of transport, and transport and logistics systems. The factors influencing the development of transport and industries on the region's economy have been identified. Based on the data obtained from statistics, regional economics, relevant ministries and agencies, as well as rom scientific research carried out by the authors earlier, the results of the research into advantages of the main types of transport have been provided for a number of indicators used in the justification of regional transport systems in line with the problems to be solved. The article provides a step-by-step methodology for assessing the comparative advantages of inland waterway transport. The method of hierarchy analysis to justify the type of transport is recommended, which will lead to the faster achievement of the goal set by the subject, or to identification of the priority way to achieve the management goal and develop the transport and logistics system in the region.
