Purpose – the purpose of the article is to develop a conceptual model of the company’s financial logistics based on the system dynamics principles. Research methodology – the article is based on the system analysis and system dynamics methods to define, classify and simulate a company financial flow. Findings – the definition of financial logistics for a business system has been defined. The authors make a classification of the company’s financial flow by the main economic activities and time series factors. Research limitations – commercial data, used for the practical implementation of the model, are confidential and cannot be disclosed. Practical implications – the model is implemented by transformation of a system dynamic flow graph into VENSIM programs. It may estimate the stationary trajectory financial flow and short-term and long-term gaps. Originality/Value – the conceptual model of the company’s financial logistics is determined based on the system dynam-ics principles. The model includes the advantages of the financial management methods and contemporary econometric analysis instruments based on a system dynamics.

Information and decision support system is the most important part of each enterprise management process. The sea commercial port is a difficult business structure, which unites the functions of logistics operator, transport terminal, international gate and classical market agent. Therefore, they decision support system determines the specific efficiency principles of the managerial functions automatization. The observance of general and specific principles implies the initial theoretical justification of the sea commercial port needs. It proves, that the efficiency of the sea commercial port information system is based on general theoretical principles of building sustainable information systems, instrumental principles of certain business processes management, specifics of commercial ports and maritime operation management. The architecture of the sea commercial port decision support information system, which uses its efficiency principles, is proposed. They are presented as design and intellectual data collection methods, summary report generation instruments and so on. The five key stages for improving the efficiency of the sea commercial port decision support information system are improved. The paper shows that information system efficiency is evaluated by the general profitability and the partial indicators of value adding and cost saving for its structure elements.

The article is devoted to the adaptive management of the innovative development of enterprises in the conditions of the national economy digitalization. The research used such methods as induction and deduction, scientific abstraction, dialectic, systematization, analysis and synthesis, abstract-logical generalization and graphic. The study proved the dependence between the speed at which enterprises achieve sustainability in relation to permanent changes in the external environment and the level of efficiency and effectiveness of their activities, in connection with which the factors influencing the innovative development of enterprises and the adaptation of their management system were analyzed. The authors attributed the following factors to the mentioned factors: digitalization of the national economy; processes of globalization in relation to the economic system; increasing the level of competition, scientific and technical progress and its leading trends; permanent complications of the operating system of enterprises and its processes; repurposing enterprises and their business processes taking into account the constant development of digital and information technologies to meet the needs of customers, the effectiveness and efficiency of the results of the companies' activities. It has been proven that adaptive management is the basis for the formation of an enterprise's adaptation strategy at all levels of management. A system of adaptive management of the innovative development of enterprises in the conditions of the national economy digitalization has been formed.
