Disproportions and Bottlenecks in Combined Production Flows of Metallurgical Manufacturing

World experience testifies the existence of significant disproportionate conditions for the functioning and development of the state, regions and enterprises. Disproportionality is observed in economic, social, environmental and other directions of development. The existence of significant disproportionate conditions for development indicates that existing opportunities are not being fully utilized. The subject of the study of this work is the internal production disparities of the enterprise as the main element of the economy. The purpose of the article is to improve the method of estimating the disproportionality of functioning and development of the enterprise in the conditions of combined production flows of metallurgical production. Achieving this goal requires implementation the following tasks: analysis of theoretical principles and methods of estimating the disproportionate functioning and development of enterprises and its subdivisions; analysis of theoretical positions for determining bottlenecks in combined production flows of metallurgical production; selection of baseline data to evaluate the disproportionate functioning and development of the enterprise. There is a need to create optimal proportions between the productivity of the main units (blast furnaces and furnaces, converters, rolling mills) and throughput capacity of the auxiliary and service workplaces, as well as between the production departments of the enterprise. The classification of disproportions is proposed. It is determined that there are the following in-house imbalances of production capacity and capacity of equipment: factory, inter-department, department and site. The analysis of bottlenecks in combined production flows of metallurgical production is carried out. Bottlenecks in combined production flows are classified into local, nodal, and through. The disproportionality factor is inversely proportional to the proportionality factor and is calculated as the ratio of the maximum value of the indicator to the minimum value. As an example, the calculation of the coefficients of, inter-department and site disproportionality. The results of this study develop and complement the theoretical principles of economics and organization of production regarding the proportional functioning and development of enterprises.
