The present paper is devoted to show and
formalize logistics problems emerging on boarders between
different logistics environments while crossing them by supply
chain. The said problems consist of increasing logistics risk and
transaction costs. It is shown that the solution of these problems
constitutes a significant reserve for increasing the competitive
advantage. The comparative-analytical approach is used to
build a double-prism model of international logistics
management. Crossborder supply chain integration is
formalized using vector representation in a pair of ndimensional
spaces of logistic significant marketing variables. A
prospective model of digital real-virtual cyberspace is presented
as a hypothetical example of a fully digitalized logistics
infrastructure. Didactic use of paper materials is explained.
