The article presents an assessment of the impact of information technology and the Internet on the e-commerce sector in Russia and in the world. The analysis of the state of the e-commerce market in Russia, as well as in several other countries leading in terms of the volume of this market, is carried out. One of the possible approaches to modelling material and information flows of an online store is considered. Based on a review of the basic methods for modelling discrete-continuous economic and technical systems, the feasibility of using the apparatus of Petri net structure theory for modelling the operation scheme of an online store is substantiated. It is proposed to use a modification of Petri nets focused on modelling and analysis of discrete-continuous systems by including priority transitions, as well as the delay time of labels in positions and transitions. A model of information flows of the online store in the form of a modified Petri net is built.
