在分析复杂信息系统的基础上，以系统理论为指导，借用多代理技术的思想，针对强对抗、强约束条件下复杂信息系统的特点，提出了复杂信息系统构建的一种新方法——多活性代理方法（MLAM, multi living agent method）；同时，在系统层次上指出了基于多活性代理复杂信息系统的基本内涵、与现有系统理论之间的衔接和区别；最后给出了基于活性代理方法的复杂信息系统研究的基本内容和两个例子。希望多活性代理方法和研究内容的提出可以进一步促进科研人员开展复杂信息系统的研究，开辟新的研究领域。

Based on the system theories, this paper discusses the characteristics of complex information system under the strong restraint and strong antagonism conditions and proposes a novel method of constructing complex information system, i. e. multi-living agent method ( MLAM) . Then, the relationship and the difference between the fundamental meaning of MLAM and the existing system theories are studied. Finally, the research scopes of MLAM are outlined and two examples are given to illustrate this method. It is hoped that the proposal of MLAM can help develop a new research field and more people devote to this field.
