The work addresses the issues of multi-criteria optimization of the target indicators of the manufacturing process of products on metal-cutting machines. The effectiveness of the optimization process directly depends on its level of detail and the optimal choice of targets and control parameters. The process of changing the structure and properties of the product during its manufacture can be represented as a hierarchical model based on the decomposition of goals that must be achieved within the framework of the selected control levels. This goal hierarchy ultimately improves process efficiency through detailed analysis and optimization of targets for individual structural elements of the model. This describes a multi-level hierarchical model for optimizing the machining process, comprising five levels of control. The following control levels are identified: technological process, processing stage, technological operation, technological transition, working stroke. Control parameters, individual optimization criteria, and vector optimization criteria are defined for each structure element of the hierarchical model. The practical implementation of the developed control model is presented on the example of optimization of the target indicators of the Valik product. A graph of changing the states of a control object during its manufacture is presented. The problem of optimizing the target indicators of one of the intermediate states of the control object is solved. The practical significance of the work lies in the development of a hierarchical model, which is the basis of the software module for multi-critical optimization of the process of manufacturing products on metal-cutting machines.
Keywords:multi-criteria optimization, technological process, vector optimization criterion, particular optimization criterion, hierarchical model, structural elements, machining, technological transition, technological operation, working stroke
