Control of price of services provided by companies of telecommunications industry

In the paper for the description of dynamics of behavior of user's base of companies of telecommunications industry the logistical model of Trays–Volterra with delay on time is used. The problem of identification of parameters of the model on the basis of real data of user's base and the tariff policy of cellular communication operators is considered. The problem of optimum control of behavior of the enterprises on the basis of L. S. Pontrjagin maximum principle for systems with constant delay is numerically solved.
