摘要：针对主观偏好影响在供应系统演化过程中的重要作用，提出了带有主观偏好“特定选择”机制的供应网络结构演化模型．研究了一般供应网络的结构特征与形成机制．构建了主观偏好选择表达式．设计了偏好选择的主客观影响权重系数，使得模型中主观偏好影响权重可调．通过模拟研究，分析了模型参数与网络结构的关系．研究结果验证了模型网络与现实供应系统基本结构特征的一致性，表明了所建模型能够较好地反映供应系统的基本结构特征。能够为基于系统结构的供应系统动力学行为研究，尤其是考虑主观决策偏好的供应系统行为研究提供支持．

英文摘要：

In view of the important role of subjective preferences in the evolution of supply systems, a new structural evolving model of supply chain is proposed. The structural characteristics and the formation mecha- nism of general supply networks are studied. A subjective preference expression is constructed. The subjective and objective influence weight of preference selection are designed, which can adjust the weight of subjective preferences. The relationship between model parameters and the network structure is analyzed by a simula- tion. The results verify the consistency of the basic structural characteristics of the model network and the real supply system. This indicates that the model can reflect the basic structural features of supply system and give support to researches on dynamic behaviors of supply systems based on the system structure, especially on supply system behaviors considering subjective preferences of decision-makers.
