W pracy przedstawiono projekt wspomagania obsługi magazynu zbożowego przez system ekspertowy. System zapewnia wspomaganie obsługi zakupu i sprzedaży zboża, pomaga w podejmowaniu decyzji o jego przygotowaniu do przechowywania, umożliwia określenie, do którego zbiornika magazynowego będzie skierowane zboże podając przyczyny takiej decyzji. Program umożliwia również nadzorowanie eksploatacji magazynu.

The proposal of store operating is presented in the paper. Expert system not only enables purchase service and grain selling but suggests how to prepare it to storage process as well. Expert system suggests where to store the grain, what silo should be used and why. Expert system provides grain store operation supervision.

Praca przedstawia organizację magazynu zbożowego na przykładzie magazynu zbożowego w Proboszczewicach należącego do spółki Elewarr. Przedstawiono kolejne etapy podejmowania decyzji dotyczących zarządzania przepływem zboża. Etapy te ukazano w formie algorytmów będących podstawą do przeprowadzenia analizy systemowej procesu.

An article shows the organization process of grain storehouse. Grain storehouse of Elewarr Company in Proboszczewice was taken into consideration. An order of decision taking according to grain flow was shown. The stages of decision making were shown as algorithms wich would be the basis for systems analysis.

Each airplane is not only operated in a level steady flight, but also has to perform a number of manoeuvres. Even for airliner or transport airplane some of these manoeuvres can be rapid and it is the reason that extreme loads generated in such manoeuvres on the tailplane have to be calculated. These loads are responsible for the state of strain, elastic deflection, fatigue and other phenomena. Among different manoeuvres considered in this paper are motions following a sudden deflection of elevator and response to a vertical gust Airplane was assumed to be a rigid body of three degrees of freedom in symmetrical motion. The panel method was used to compute aerodynamic coefficients. Unsteady forces and pitching moment were computed using classical stability derivatives. Elevator deflection was of the step change type, gust was assumed to be either of the step change type or harmonic, with a gust cycle time corresponding to the time to travel a distance equal to 25 Mean Aerodynamic Chord. In all cases a jump type elevator deflection was assumed to last for 1 second, whilst the airplane response as observed for 3 seconds. The airplane motion, its velocities, accelerations and load acting on the tailplane were calculated by means of numerical integration of the ordinary differential equations of motion.
