Fuzzy Optimization Problems in Wavelength Division Multiplexing (WDM) Networks
نویسندگان
چکیده
The basic wavelength division multiplexing (WDM) routing and provisioning problem is considered in this paper. The literature is replete with prescriptive integer programming models for various versions of WDM design problems, but in no case they consider the real situation of solving them taking into account the former nature of the problem, that is, its inherent vagueness. In this paper this vagueness is assumed and handled by means of fuzzy sets based methodologies. In particular a Fuzzy Integer Linear Programming model is proposed to be used as auxiliary model for solving the former WDM provisioning and routing problem. Besides a heuristic algorithm solving it is outlined.
