Based on studies of domestic and foreign scientists, it was established that the intensive process of digitization of the economy generates the emergence of new digital technologies and solutions, the specificity of their impact on business models of enterprises needs additional scientific study. Generalized conceptual diagram of the system modeling process is proposed. It has been found that digital transformation has led to changes in the business process management of enterprises, which have been driven by improved efficiency and manageability of operations, and have become a challenge oriented to the experience of successful global companies. A business process model was built "as is", then a model "to be" be based on them modelling the digitized business process network of JSC Ukrtransnafta, which was carried out using BPMN Visio 2010 Premium.

The article proposes two methods for evaluating the financial efficiency of a business model of industrial enterprises. In order to evaluate the financial efficiency of the business model of an industrial enterprise, a system of single indicators for assessing the financial condition of the enterprise by such components as financial stability, liquidity and solvency, business activity and profitability was formed. Fishburne's rule weights the major components of an integral measure of an enterprise's business model financial performance. In addition, an integral measure of the financial performance of the business model is modeled using the fuzzy set method and taxonomic analysis, which will help to evaluate the financial performance level of the business model more objectively. The comparative analysis of the obtained results by different methods of calculation of integral indicators is carried out.
