AB - Computer networks and power transmission networks are treated as
capacitated flow networks. A capacitated flow network may partially fail due to
maintenance. Therefore, the capacity of each edge should be optimally assigned to face
critical situations—i.e., to keep the network functioning normally in the case of failure at
one or more edges. The robust design problem (RDP) in a capacitated flow network is to
search for the minimum capacity assignment of each edge such that the network still
survived even under the edge’s failure. The RDP is known as NP-hard. Thus, capacity
assignment problem subject to system reliability and total capacity constraints is studied
in this paper. The problem is formulated mathematically, and a genetic algorithm is
proposed to determine the optimal solution. The optimal solution found by the proposed
algorithm is characterized by maximum reliability and minimum total capacity. Some
numerical examples are presented to illustrate the efficiency of the proposed approach.
