Kiriya R. Conveyor transport systems function process modeling of ramified structure and methods to improve their efficiency

The dissertation work is devoted to the mathematical modeling of conveyor transport systems function processes of the ramified structure with accumulate bunkers and without ones working in different modes, and also methods to increasing its efficiency. There are mathematical models of the simplest system “conveyor-bunker-conveyor” on the Markov’s processes theory basis are developed. It done for two accumulate bunker working modes: without control and under control ones (maintenance of the freight in defined limits). For the conveyor transport systems with successive, parallel conveyors connection and with self-similar structure without bunkers and with bunkers the middle dynamics Markov’ processes method was used. Recurrent dependences, determining average capacity, middle energetic transportation capacity and middle specific capacity of the system of transport, are obtained. The systems of equalizations for middle and dispersions of times of level freight and unloading of accumulate bunker working in out of control and guided modes are got. The using of the Pontryagin’s method allowed to define the middle volume of freight in a bunker. Tasks had solved and as result the optimal control and adaptive one algorithms of the conveyor transport system with accumulate bunkers working in the guided mode are got. The design methodic for carrying capacity, energy capacity, algorithm structures and parameters, optimal and adaptive conveyor transport system management is proposed. Its application will allow increasing the conveyor transport system carrying capacity up to 50% and decreasing load transportation specific capacity down to 30%. It will be done when optimum and adaptive control conveyor transport system management and controllers and frequency management methods for electric conveyor and feeder engines will be used. Obtained results in recommendations for design and exploitation conveyor transport system species are passed into design, construct and mine organizations of Ukraine. It passes to studying process for mine, metallurgical and technologies skills of education institutes. Keywords: conveyer transport system, accumulated bunkers, functioning processes, Markov’s processes, average capacity, specific energy capacity, efficiency criterion, optimum and adaptive management.
