The article examines the problem of mining enterprises main engineering processes system of mechanization structure
optimization. It is suggested to consider the whole complex as a subsystem of a large technical system – a mining
enterprise – on the basis of the theory of sets with the use of the main principles of system analysis. Possible variants of
means of mechanization structure are represented in the shape of neorgraphs with various level of specification.
At the heart of the choice of optimal decisions there is the method of hierarchies analysis, worked out by T. Saaty.
The method of alternative hierarchies intends the use of hierarchical structures, which represent a mathematical
instrument for qualitative modeling of complex problems. At the top of the hierarchy is the main goal; the elements of the
lower level are the set of variants of achieving the goal (alternatives). By the example of the choice of crushers for open
pit crushing installations it is shown that this approach allows significantly reducing time and resources as compared to
the optimization of the whole complex of machines at the mining enterprise on the basis of graph.
Key words: system analysis; systems engineering; crusher; structure model; theory of sets; neorgraphs; hierarchies
analysis method.
