Bilans cieplny w budynkach dla trzody chlewnej w ujeciu systemowym

The objective of this study was to determine the system to control and evaluate heat balance in hog barns, as an element of general concept of selecting plant and equipment for hog farming usable for technical advisory service. A subsystem set theory model was developed as well as Pascal 7.0 based databases for IBM PC compatible computers. Traditional calculations were used to develop data processing algorithms, i.e., algorithms for determining relational structure of modeled subsystem. The construction of building wherein the livestock needs are considered proved to be a fundamental problem. The proposed system of controlling and evaluating heat balance in hog barns makes it possible to take into account all significant factors and their mutual interactions both in the facility design process and in its operation. The set theory model used herein makes possible the introduction of new elements into the databases of the programmed subsystem of regulating and evaluating heat balance in hog barns.

Przedstawiono strukturę podsystemu kształtowania bilansu cieplnego w chlewniach. Podsystem będzie wykorzystany w ogólnej metodzie doboru środków technicznych w systemie doradztwa w chowie trzody chlewnej. Zaprezentowano model teorio- mnogościowy podsystemu opracowany na podstawie metod inżynierii systemów. Model został oprogramowany w języku Pascal 7.0 na mikrokomputery kompatybilne z IMB PC/AT.
