A structural-functional model of cross-border logistics as a process subsystem of company's foreign trade activity tetrad
<b>Subject.</b> To assess the potential of corporate management of company’s foreign trade activities, the article considers the structure and functionality of its constituent systems and, particularly, the cross-border logistics as a process subsystem, are of interest nowadays. <b>Objectives.</b> Based on the main provisions of the theory of system economics, the study aims to build a structural and functional model of cross-border logistics, which is a process subsystem of the tetrad of company's foreign trade activities. <b>Methods.</b> The study draws on the systems approach, methods of analysis and synthesis, grouping and comparison, abstraction, generalization, analogies, logical analysis, and the management theory elements. <b>Results.</b> I built a structural and functional model of cross-border logistics as a subsystem of the tetrad of company's foreign trade activity, which meets the previously formulated conditions for model verification. The paper particularizes the systems of four types of basic typology and substantiates their inclusion in the process subsystem; discloses the essence of general economic processes implemented by each system, and determines the content of produced and consumed goods. I developed a model of interaction between administrative (customs regulation) and corporate (cross-border logistics) tetrads. <b>Conclusions.</b> The model enables to identify four systems that due to their functionality are responsible for movement of goods across the customs border, and to describe this process from the perspective of space-time approach. The movement of goods across the customs border is determined by the interaction of administrative and corporate tetrads, and the key factor is the activity of process subsystems.
