Kosylov S. Information technology of decision support for management in enterprises using conveyor type production process

Object of the research is an automated information processing that accompanies the implementation of production program. The subject of the research is the creation of tools (models, rules, algorithms and software) for information technology automated data processing at the production planning and operational management. The aim of the thesis is to solve the problem of optimal decisions making in enterprises with conveyor type production process and characterized by a variety of non-linear technological constraints, technological pauses and limits on the terms of orders execution. The following results have been obtained: developed dual method of calculation of indicators of the production program, based on the created logic-formal and analytical model of interrelations between the characteristics of orders and blanks for production, taking into account technological limitations. Developed rules of time parameters formalization for statement of optimal planning problems including polynomial model for calculating the duration of execution of orders and the model of limit order execution terms. Formed rules for making optimal operational decisions to correct the production program at a deviation from the plan, which ensure immutability of optimal plan indicators outside the operational management interval and distribute tasks of operational management. Improved methods of optimal planning problems numerical solution by formalizing nonlinear constraints in the form of penalty functions for use in genetic algorithms. The information technology for automating calculations in the course of solving problems of optimal planning and management have been formed and brought to engineering techniques in the form of algorithms and software for DSS in enterprises of the type described above. DSS trial testing have been conducted at the PSC "Donetsk metallurgical plant".
