Pylypenko I. Decision-making in the management of branched-cyclic technological processes

The object of study is branched-cyclic technological processes. The aim of the research is to improve the efficiency of branched-cyclic technological processes based on information technology of decision-making in the management of such processes. Methods of probability theory, computer modeling, decision-making are used. Theoretical results are: for the first time the model of management of branched-cyclic technological processes is developed based on undefined cyclic graphs and inhomogeneous Markov chains, which allows to increase the adequacy of the model of management of such processes and reduce losses; the method of losses assessment in the management of branched-cyclic technological process is improved, which differs from the existing methods by using a combination of statistical and fuzzy estimates of losses in the executing of technological process operations, that allows to extend the scope of the method; the method for prediction a reasonable number of repetitions of the cyclic technological process was further developed, which is characterized by the sharing of non-homogeneous Markov model in conjunction with the operator method of modeling systems in conditions of uncertainty, which improves the quality of decisions. Practical results are: algorithms and programs of information technology of decision-making in the management of branched-cyclic technological processes are implemented. The degree of implementation is: the results of research have been implemented in company "Spilna Sprava" and in the educational process of Vinnytsia National Technical University. The scope (industry) of application is control of technological processes.
