In this work I am assisted by my scientific supervisor. His name is Smirnov Yuri Nicolaevich. He is the head of our Chair “The mathematic model-building and information technologies in economics”. With him I and my group mates took part in some All-Russian conferences, where we sent our reports on economics and information technologies. One of my reports called “The mathematic model-building of marketing”. In this work I described possible mathematic methods and models with aim of which the firm can optimize all its marketing activities. Our materials were published in the scientific collections of articles in many towns of our country.
