中文摘要：
划分层次结构是进行复杂系统分析和决策的基础。为了使复杂系统的层次结构划分更加合理、直观，提出集成DEMATEL／ISM构建系统层次结构；给出二者集成的理论依据和算法；介绍增添虚节点完善复杂系统层次结构的方法；最后文章通过实例验证上述方法的合理性和有效性，表明DEMATEL和ISM方法的有效集成可降低可达矩阵的计算量和计算复杂度，为实际复杂系统的分析和决策提供了新思路。
英文摘要：
Establishing hierarchy structure is generally the foundation of the analysis of complex systems. To make the hierarchy structures of the complex systems illustrative and reasonable, a new method is first proposed to establish the hierarchy structures for complex systems based on the integration of DEMATEL and ISM after the theoretical foundation and corresponding steps of the integration are analyzed ; and then the concept of dummy node is advanced to improve on the hierarchy structures of the complex systems; finally an example is used to illustrate the methods mentioned above. Through the integration algorithm mentioned in the paper, the rearchability matrix of ISM can be obtained easily.
