Malienko A. Automation of coal mine scheduling processes based on decision-maker's decision-making system

The Thesis is devoted to the relevant and important scientific problem - im-provement of coal mine scheduling process efficiency. The main purposes of the thesis are: construction of the model for calculation of stochastic relations between controlled parameters of the coal mine functioning, development of the mathematical model and operation algorithm of dispatcher's decision making system through optimization of scheduling process that involves technical and economical constrains as well as binding time determination. In order to determine time moments when the equipment is beyond its appropriate operating modes, author proposed a method, based on the approximation of the autocorrelation function using the least squares method and the Rice problem. The method allows determining the number of such moments and preventing the mine equipment downtime. The developed operation algorithms of the main technical processes and their implementation in the simulation model allow simulation of technical proc-ess for the coal mine of any complexity, taking into account the conveyor transport capacity, storage hoppers, the use of coal surface storage, in order to determine the cost-effective modes for the coal mine functioning. The analysis, performed with the use of probabilistic experiment, allowed to confirm the efficiency of the applied methodology for the developed dispatcher's decision-making system. Moreover, the developed dispatcher's decision-making system allows to evaluate the management efficiency, reduce the time of decision-making and increase the validity of the decisions made by the dispatcher of coal mines when performing the planned indicators of the coal mine.
