Abstract: Express shipment service requires that shipments should be picked up and delivered within specified time intervals（e.g.，24 hours，48 hours），so usually it is the airplane that accomplishes the long-distance transportation.The classical models on network design are reviewed.Then，considering the possible restrictions，two kinds of solutions facing the multi-commodity network without a hub are presented，which are solution based on NLP model and solution based on improved ESSND model.At last，the use of these two kinds of solutions is clarified in details，and the conclusion is that the solution based on improved ESSND model can obtain a near optimization result.

Key words: network design, non-hub network, multi-commodity, express shipment service
