The Study on Emergence and Optimization of SDN Cooperation Subnet

Abstract: Aiming at overcoming the instability of the chain structure of the supply chain, the lack of flexibility and adaptability of the supply chain caused by the "core enterprises" in the chain, and such deficiency as easy occurrence of broken chain, etc., this Paper introduces the concept of Supply and Demand Network with multifunction and opening characteristics for enterprises (SDN). This Paper carries out the study on SDN cooperation subnet, build a model to depict the emergence of the SDN cooperation subnet from the perspective of the hierarchy. Based on the Kruskal algorithm and the Dijkstra algorithm respectively, studies on the optimization of all enterprises and individual enterprise are given, and the numerical examples are also presented. The model has a practical significance for guiding the enterprises in SDN cooperation subnet to carry out the cooperation target selection and global strategy optimization.
