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.

Artykuł przedstawia dane na temat wyników osiągniętych przez polską elektroenergetykę w latach 2012-2014 w powiązaniu z wybranymi wskaźnikami makroekonomicznymi. W analizowanych latach polska elektroenergetyka osiągnęła zysk brutto na działalności energetycznej, co nie było związane ze wzrostem wolumenu sprzedaży lub wzrostem cen energii elektrycznej. Artykuł przedstawia również informacje obrazujące poziom sprzedaży energii elektrycznej, wielkość cen i kosztów jej dostarczania oraz wyniki finansowe trzech dużych spółek energetycznych notowanych na Giełdzie Papierów Wartościowych.

In this paper some economic data of power sector in Poland in 2012-2014 and macroeconomic indicators are presented. In these two years the Polish power sector has achieved the level of gross profits, which was not associated with an increase in sales volume or increase in electricity prices. The paper presents also basic information on the sales level, electricity prices, costs of electricity supply and some financial indicators of the three main power sector companies that are listed on the Warsaw Stock Exchange.
