Sistema y Gestión de Telecomunicaciones

Profound changes have affected the European telecommunications sector in the last 15 years. With its liberalization at the end of 1990s many telecommunications companies, such as ‘International Telecom’ had to adopt advanced managerial accounting systems that could provide them with detailed and accurate cost accounting information. To this respect Activity-based Costing revealed crucial to aid International Telecom to face fierce competition coming out from the new operators that came into market and to respond to regulatory demands.

Telecommunication is one of the unavoidable utilities of daily life. Telecommunication service providers have data records of its users. These records are represented by crisp graphs. Certain parameters like center persons, churn prediction, etc. are more perfectly calculated if the data are represented by fuzzy graphs. In this paper, we have introduced a fuzzy telecommunication network (FTN) using fuzzy graph theory.Star persons and related terms are defined in this fuzzy telecommunication network.A small example is described to illustrate the network. Churn prediction is a big issue for telecom service providers. This study introduces churn prediction in the fuzzy telecommunication network. New idea on measurement of churn prediction is presented here.
