New aspects of the methodology for assessing the complexity of the structure of technological systems of the mining and metallurgical complex

Purpose. To develop a new approach to evaluating the complexity of structure technological systems mining and metallurgical complex with proposed integrated index. The practical application this indicator is due methodological difficulties arising when determining hierarchical level elements studied. Methodology. A systematic applied that allow us explore industrial complexes equipment as objects present them in form systems. Methods analysis synthesis are used identify common known methods for estimating process decomposition simulation applied, which submitting models structural-element schemes. Findings. quantify complex, system performed by method successive cut-off element connections system. Using provides high accuracy reliability comparing different levels consisting number subsystems elements. Approbation developed on example pelletising plant pellets No. 2 Pivnichnyi Mining Processing Plant (Kryvyi Rih). It shown real occurs mainly series connection extra rather than creating relations. increase index relative management structure, it reasonable use combined series-parallel additional equipment, ensures highest Originality. originality assessing system, essence consists cutting off Practical value. value authors estimate contrast method, quantitative evaluation without performing operation formal description structure. result, reduces process.
