A multicretira approach in design of optical networks

Optical networks present a fast and reliable medium for transferring information, especially high volume data. We investigate design issues of optical networks in light of multiple criteria which can be conflicting, such as congestion, total flow¸ delay ecc.In examples two criteria are considered at a time with arbitrary topology of the network assumed. We present a tabu search heuristic algorithm that combines two criteria. It is implemented as a two phase strategy dealing with diversification and intensification of search. Computational experiments include consecutive runs with different sets of weights associated with the given criteria.
