Routing and wavelength assignment (RWA) is one of the vital optical network issues of optical networks. With the tradeoff between the idle ratio and reliability of the candidate route, this paper researches a dynamic RWA algorithm for optical networks by introducing a factor of RWA dynamic weight to reach high demands of transmit speed and transmit quality. With the comprehensive consideration of...
The next generation optical networks offering higher bandwidth have advanced the possibility of high capacity accessing. However, the deploying and operating cost of the network with such high capacity is significant. The network optimization is a promising research field in recent years. Employing dynamic optimization method and with the objective of minimizing the load-balancing cost, this paper...
The optical network owns the high bandwidth, but this performance works inefficiently in the grid structure with high requirements. Flexible resource scheduling scheme is benefit to elaborating the high bandwidth performance of optical grid network. This paper studies the resource optimization strategy based on the game theory, and proposes a dynamic resource scheduling scheme in the optical grid...
This paper introduces the scheduling algorithm of a computer simulation and scheduling system for hot strip mill. The mathematical model of hot strip mill scheduling problem (HSMSP) is formulated. A hybrid heuristics method is proposed, based on parallel strategy, which integrates domain expertise, genetic algorithm (GA) and tabu search (TS). Domain expertise is used to classify and sort production...
0-1 integer programming model of steel making scheduling was presented. Boolean algebra was applied to restrict the search space of particle swarm optimization to 0-1 space. As for the difficulty of constraint problem of 0-1 integer programming, a cooperative particle swarm optimization(CPSO) algorithm was proposed, which embody two particle swarms, one's goal is to minimize the objective function,...
