Abstract: With the economic globalization,diversity of customer requirement and many uncertain factors,a traditional supply chain must be transformed to an adaptive supply network.Adaptive supply network has gained more and more attentions from both enterprises and academic areas.A primary study of adap tive supply network is given.Learning is emphasized as an important way to implement the transformation from traditional supply chain to adaptive one.A framework for adaptive supply chains is proposed based on complex system theory.Finally,a complex network model for adaptive supply chains is established.Several important statistical characters are given.Simulation results show this model is useful to understand the complex evolution behaviors of complex supply chains.

Key words: adaptive supply chain, adap tation, learning, evolution, complex network
