Hierarchical selection of technological equipment for the production system

Abstract

In this paper, a study of technical and economic indicators is used in the design and selection of production equipment. Since the indicators currently used are considered independently of each other, they are rarely agreed upon. To overcome this drawback, it is proposed to consider them depending on five levels: parametric, structural, technological, economic and social. This immediately introduces the hierarchical subordination of indicators and their connection with social needs and a rapidly changing economic environment. As an example, a reconfigurable production system is considered, the equipment load factor, which requires increased flexibility from the system, is chosen as the main parameter. The reconfigurable production system, in addition to software or parametric flexibility, allows you to increase it due to the ease of changing the production structure, and when it is not enough, and this can move to reconfigurable production, which provides greater adaptation to changing conditions and expands the range of products produced through the use of transforming machines. The developed approach is applied to the technological system of a regional enterprise. The results, presented in the form of histograms, show a progressive increase in the equipment load factor as it moves along the hierarchical scheme. Thus, to answer the question what equipment should be designed or selected at the operating enterprise, it is necessary to consider five hierarchical levels with their own indicators each. At the same time, the indicators of the lower level can be determined only after the determination of the indicators of the higher level.
