A Pareto frontier for node survivable computer network design problem

In a survivable network design problem in cloud computing, one important goal is minimizing the network building costs, and the other important goal is maximizing the technical capability of the network. The literature investigation shows that the previous studies for computer network design proposed models only considering one of the above-mentioned goals and neglected the other. In this paper, a new model is developed in which the node survivable network design problem is formulated as a two-objective optimization problem considering both goals. To solve the formulated problem, several two-objective optimization procedures are adopted and the results are discussed. Finally, numerical simulations are performed for two real examples and the obtained results are discussed.
