摘要：It is pointed out that the entropies of structure, information and the effectiveness entropy between knowledge and organization structure are main entropy sources of supply chain network in this paper. Firstly, establish entropy model of fractal supply chain network organization structure. Secondly, fractal knowledge management network outside independently organization structure is set up. Moreover, knowledge and organization structure to have the whole similarity, and its entropy model is established. Furthermore, the effectiveness entropy model is builded. Finally, the entropies of structure, information and the effectiveness entropy are summed to research. And the model shows that fractal structure has prominent effect of dropping entropy.
