摘　　要：服务产品具有无法库存等特征,要求服务供应链结构具有较强的自组织能力,因此需要找到一种能适应环境和通用的动态供应链重构模式,而分形供应链具有自相似性、自组织、自优化等特点,可以兼顾供应链组织结构的稳定性和灵活性。基于分形理论,将服务供应链分解为若干个分形供应链元,建立分形供应链元间相似性测度模型,可以较准确地研究服务供应链网络组织结构。对港口服务供应链仿真实例的分析表明,可以利用自相似维数的测算结果更好地认识现实复杂的服务供应链网络。Service products have the characteristics such as non-inventory and so on and require service supply chain structure with stronger self-organizing ability,thus,a general dynamic reconstruction model adapting to the environment needs to be found and fractal supply chain has the characteristics such as self-similarity,self-organization,self-optimization and the like and can balance the stability and flexibility of supply chain organization structure.Based on fractal theory,service supply chain is decomposed into a lot of fractal supply chain cells,the calculation model on the similarity between fractal supply chain cells is constructed and service supply chain network organization structure can be accurately studied.The analysis of simulation examples on port service supply chain shows that the calculated results of self-similarity dimension can better study present complex service supply chain networks.
