Application of the apparatus of fuzzy logic to solving management problems in telecommunication companies

Matrokhina Kristina Vasilevna

The article presents an information traffic control algorithm in telecommunication networks, built using the fuzzy logic apparatus. As the base of fuzzy control algorithm, the Mamdani algorithm was chosen. Corresponding operations of fuzzy inference have been determined, allowing to give the control algorithm “flexibility” based on taking into account the accumulated practical experience of staff in the process of operating a telecommunication network. Initial dataset has been generated based on the technical characteristics of the network, as well as on the basis of expert data obtained during its operation. The required linguistic variables used to control the network were specified, for these variables the necessary membership functions of three types are constructed. The base of fuzzy inference rules is formed, on the basis of which the value of the output linguistic variable is found. The results obtained allowed to identify the most effective model of the membership function, which must be used for adequate fuzzy control.
