Based on the theory of system dynamics, this article analyses the system composition of a university library intelligent knowledge service (IKS) and its relevant functions. First, we designed a system dynamics model involved the steps and flow of system modelling, the analysis and frame diagram, the system boundaries and their settings, and the system causality model. Furthermore, the system simulation of the IKS is carried out with result analysis, validity test and application analysis. The system simulation results show that (1) the model can simulate the system operation processes of a university library IKS, (2) the model reveals the relationships and the operation trends among the elements of the IKS and (3) the effective implementation of a library IKS can be improved by following the essential law of service development, paying attention to the coordination and interaction among constituent elements, and influencing measures around key variables.

本文基于系统动力学理论，分析了高校图书馆智能知识服务(IKS)的系统组成及其相关功能。首先，我们设计了一个系统动力学模型，涉及系统建模的步骤和流程、分析和框架图、系统边界及其设置以及系统因果关系模型。此外，通过结果分析、有效性测试和应用分析，对IKS进行了系统仿真。系统仿真结果表明：（1）该模型能够模拟某高校图书馆IKS的系统运行过程；（2）模型揭示了IKS各要素之间的关系和运行趋势；（3）有效实施了IKS图书馆 IKS 可以通过遵循服务发展的基本规律来改进，
