The attention to effective logistics system and material flow promotion has been increased in up-today economic transformation in Ukraine. Meanwhile, core process of any firm or system functioning still have place. The profit motive and high level of services for consumers’ purposes miss risk of capital erosion due to delaying of payments. Lack of financial flows make difficult of making any action, especially supporting high level of logistics servicing. Existing scientific and methods to the logistics management consider individually financial and material flows separately. The interaction of them needs further exploring. A frequency and transportation volume of logistic chain is unevenness and depends on seasonal consumption. Authors simulate the transportation service numerous different logistics chains with compatible cargos. Schedule of vehicles analysis per months and years shows irregularities of vehicles use in different systems. Orders redistribution between vehicles, led to synergetic effect that demonstrated by vehicles’ quantity decrease. Authors modelling and simulate the transportation service mode for manufacture of building material. Estimating the total cost for using auto and rail transport. Wilson models, just-in-time models for stock management have been used. Result of using auto transport instead of rail a been reduce of costs for more than 20%. Releases operating capital can effectively use in the logistics system operation cycle. Also, such actions provide acceleration of costs movement. The paper formalized relationship models of material and financial flows interaction. The proposed approach will allow evaluating the efficiency of various modes of transport, as well as improving the efficiency of the logistics system.
