Salabai V. Optimization of business processes of machine-building enterprises in the context of digital transformation of the economy

The modern development of Ukraine’s economy is characterized by the active implementation of digital technologies, which leads to a transformation of enterprise management approaches. These processes are particularly relevant for the machine-building industry as one of the basic sectors of the national economy. Improving the efficiency of machine-building enterprises requires reconsidering the role of business processes as a key object of management, since they ensure the transformation of resources into final performance results. This determines the necessity of their systematic optimization considering the opportunities created by the digital transformation of the economy. The dissertation is devoted to the deepening of theoretical provisions, development of methodological approaches, and elaboration of tools and practical recommendations for optimizing business processes of machine-building enterprises under conditions of digital transformation of the economy. The first chapter examines the theoretical and methodological foundations of business process optimization in the context of digital transformation. Scientific approaches to the interpretation of the concepts of “business process”, “business process optimization”, “digitalization”, and “digital transformation” are systematized, which made it possible to clarify their content and determine the interrelations between them. It was established that digitalization mainly reflects the instrumental level of changes, whereas digital transformation covers systemic changes in enterprise activities. It is substantiated that business process optimization acts as a key mechanism for implementing digital transformation at the enterprise level, since it ensures the integration of digital tools into management practice and contributes to increasing operational efficiency. The second chapter analyzes the prerequisites for business process optimization of machine-building enterprises considering the macroeconomic context of digital transformation. Ukraine’s position in the global digital environment and the level of its digital development are determined. An analysis of the development of the Ukrainian machine-building sector was conducted, which revealed that, along with external instability factors, an important role is played by internal organizational problems, including inconsistency of business processes and different levels of readiness for digital changes. Based on the conducted analysis, a sample of machine-building enterprises for further research was formed and the efficiency of their business processes was assessed. The application of a system of indicators based on the Balanced Scorecard logic made it possible to conduct an integrated assessment of business process efficiency and determine the areas requiring optimization. The third chapter develops and tests a scientific and methodological approach to the optimization of business processes of machine-building enterprises, combining process diagnostics, digital maturity assessment, and economic-mathematical modeling. The digital maturity of enterprises was assessed using an adapted ADMA model, which enabled the formation of digital profiles and determination of readiness for implementing digital solutions. A cognitive model reflecting the relationships between digital maturity, business process efficiency, and enterprise performance was developed. An economic-mathematical model for business process optimization based on linear programming methods was constructed, taking into account the level of digital maturity of enterprises. The final stage of the research involved the development of a roadmap for business process optimization of machine-building enterprises, which provides for the phased implementation of transformational changes — from diagnostics and assessment to implementation and monitoring of results. The main scientific novelty of the dissertation lies in improving the scientific and methodological approach to business process optimization of machine-building enterprises under conditions of digital transformation of the economy, based on a comprehensive assessment of business process efficiency and digital maturity level, providing economic-mathematical substantiation of optimal business process parameters considering resource constraints, and including the development of a business process optimization roadmap. The practical significance of the obtained results lies in the development of scientific and methodological approaches and tools for optimizing business processes of machine-building enterprises under conditions of digital transformation of the economy. The obtained results may be used by managers and specialists of enterprises for making managerial decisions aimed at improving business process efficiency and implementing digital management tools.
