Hierarchical fuzzy situational networks for online decision-making: Application to telecommunication systems

Abstract The paper considers a new approach to online decision-making in telecommunication systems based on applying hierarchical fuzzy situational networks. This approach allows one to make efficient decisions in the conditions of dynamically changing external factors. Mathematical foundations for creation and application of hierarchical fuzzy situational networks to implement the fuzzy logical inference in telecommunication networks are presented. As a case study for implementation of the offered methods the problem of alternative multipath routing is analyzed. The architecture of the online decision-making system, based on hierarchical fuzzy situational networks and oriented on its multi-agent implementation, is considered. The generalized online decision-making system functioning algorithm is developed. The architecture of an intelligent agent of the online decision-making system is shown. The assessment of efficiency for the approach to construction of online decision-making systems demonstrates its benefits in comparison with the known probabilistic methods of decision-making in telecommunication networks. It also proves a possibility of functioning of the offered online decision-making system in a real or near real mode.
