We created a decision-making support system regarding the optimal use of metal in the two-stage process of its distribution in the production of rolled products. The learning algorithm of the melting control subsystem of the intelligent decision support system in the oxygen converter control loop was developed. The subsystem automates the operator's actions, optimizes the process according to economic criteria, and reduces the influence of the human factor on the result. Mathematical apparatus for a two-stage process of material flows allocation in the transport-logistic system and for the routing problem was implemented. We developed a new hybrid genetic algorithm GBOHGA, an optimization scheme that combines elements of BOHGA and HGDN methods and which integrates the strengths of local search with powerful global search capabilities. Due to the prevention of a significant part of the unnecessary use of the local search operator, significant savings were achieved in the number of evaluations of the objective function and execution time of the algorithm, which made the method competitive with other widely used methods of global optimization. Methods of regularization of problems of optimal control of systems with distributed parameters have gained further development Product Description popup.authors popup.nrat_date 2023-01-05 Close
