Abstract
Paper deals with the problem of supply logistic for greenhouse energy purposes. It is an attempt to estimate the proper supplies of coal, to reduce the costs of warehouse management in the analyzed horticultural enterprise. The analysis includes estimation of the object's heat demands of the, an optimal order quantity and calculation of costs of maintaining inventory. The research object is a greenhouse complex (10 ha) with tomatoes cultivation. We calculated that, the proposed inventory shaping method, to determine the order quantity of energy raw material for the needs of the greenhouse, would reduce inventory financing costs by 33.5%.
 
 
Highlights
Greenhouse production, in the era of searching for healthy and safe food, is one of the important sectors of plant production which guarantees a year-round supply of vegetables
The following values were adopted for detailed analysis: heat exchange surface, shield indicator, index was adopted as =0.5
On the example of numerical values characterizing the complex of production greenhouses, real savings possible to be generated by the application of economical methods of fuel stocks controlling were indicated
Summary
Greenhouse production, in the era of searching for healthy and safe food, is one of the important sectors of plant production which guarantees a year-round supply of vegetables. Increased costs of heating in production facilities, legal regulations (plan "three 20 targets” assuming the reduction of harmful emissions from fossil fuels combustion) force to reduce heat consumption in horticultural facilities. One such solution is to increase the walls insulation of heated objects (greenhouses and plastic tunnels). Single or double foil (with pressed compressed air), polycarbonate can be used as a greenhouse cover This material is characterized by a lower heat transfer value, a certain drawback concerning glass or foil is the lower transmission of visible light and reduction of this permeability over time
