Modeling of sales processes in the manufacturer - marketplace system

Introduction. E-commerce is becoming one of the priority channels for the distribution of goods. Marketplaces with their large segments of the target audience and a wide range of logistics, marketing, information, and other services are the most extensively growing e-platforms. It seems relevant to use mathematical tools to describe various schemes of interaction between manufacturers and marketplaces since by now scientific papers consider only theoretical issues of cooperation between manufacturers and marketplaces and do not outline the elements of this system.
