Melnikov O. Information technologies for multi-level planning in the organizational and production systems with limited resources

The work is devoted to creation of advanced information technology for the multi-level planning of complex organizational and production systems based on a set of related discrete optimization models. The multi-level model of planning of complex systems with a network representation of the processes and limited resources was developed and justified in accordance with modern requirements. Models and methods for coordinated planning of the second level of the multi-level model were created. The ergatic procedure to adapt the model of aggregation and disaggregation of the first and second levels of the multi-level model was created and systematically justified. A method for solving the NP-hard scheduling problem "Minimization of the total earliness and tardiness of independent tasks on one machine" was developed. Based on the proposed mathematics the automated system for planning and control in complex systems was created which can be used as a planning module in ACS of the organizational and production systems of various sectors of the economy.
