英文摘要In this paper, we consider a new network improvement model, which is to expand a network by adding new arcs and/ or new nodes to satisfy the excess demand. For the new arcs and new nodes, there are constructing costs for building these new facilities. The purpose of our model is to minimize the total constructing cost. It is found that even if the constructing costs for all new nodes are zero or all new arcs are zero, solving the problem within an approximation ratio 0 (In(V-1 (+ V)()) remains NP-hard, where V)(2)(1) (is the original node set, and V)(2) is the candidate node set. We also present an MIP formulation for the problem and propose some heuristic ideas to solve the problem.
