“…However, the case is somewhat different in practice. The Generation 1 casting technologies used at an early stage of development of the casting technology involved a simplified conceptual model of the technology, whereby controlled process parameters were considered as purely deterministic values [5,6].…”

The paper considers the ways of controlling the processes of producing good-quality castings by using robust methods based on the identification of objects under uncertainty, adaptive control methods, stabilization methods for automatic control systems and their mathematical description. The purpose of the paper is to practically elaborate on the task of creating robust technologies for casting based on the study of the stochastic dispersion models of the casting process parameters and to develop a method for stabilizing the casting processes and a method for stabilizing the quality parameters of the castings. The regular patterns of the stochastic dispersion of the casting process parameters were investigated based on the mechanical performance of the casting alloys, their chemical composition, the physical and mechanical properties of the molding mixtures, the dimensions of the castings, and the features of the casting production process such as pouring temperature, element loss during melting and mold hardness. The results of the conducted investigations have shown that to describe the stochastic dispersion of the casting process parameters, it is appropriate to use the Johnson system of distributions. A method for stabilizing the casting quality parameters was developed. It has been shown that it is more efficient to stabilize the strength and improve the dimensional accuracy of the casting simultaneously. With the existing production process, the dimensional accuracy of the casting corresponds to Grade 11 according to GOST 26645-85. With the increase of the dimensional accuracy grade, the metal content of the casting can be reduced by 16.3% after reaching Grade 10, by 20.4% after reaching Grade 9, and by 24.2% after reaching Grade 8.

“…The organization of production must meet the goals and objectives of the enterprise, the choice of development strategy and tactics and an effective management system. Therefore, the organization of production consists of the integration and provision of production elements, the establishment of the necessary connections and the coherence of the participants' actions in the production process, the conditions' implementation for the realization of the common economic interests of the company, the owner of production, the team and each employee [1,5]. In general, the development level of productive resources characterizes the level of efficiency of an industrial enterprise [6].…”

The relevance of the paper research is due to the fact most car manufacturers suffer significant losses and reduce production because of the falling demand. Therefore the challenge of changing the production organization model, reducing costs and increasing labor productivity through the search for internal reserves rises. The aim of the paper is to increase the production efficiency of organization at mechanical engineering enterprises. The research conducted by the authors makes it possible to conclude in modern market conditions, the cost, price and, accordingly, the competitiveness of enterprise products are largely determined by the state of the main elements of production, as well as the efficiency of their use, that is, the level of organization of the main production processes. Consequently, the authors defined the role of improving the organization of production processes in the efficiency of industrial enterprises. As a result, continuous improvement of the main and additional processes ensures the stable and long-term competitiveness of the industrial enterprise. The authors determined the main business unit of the enterprise, a description of the production unit activities was given, the main problems in the organization of workshop production were identified, the directions for improving the production efficiency of organization at the enterprise were determined. During the work, theoretical and practical research methods were used, such as analysis, synthesis, generalization of experience, experimental method, quantitative and qualitative processing of results, observation, static methods.
