针对还原论在体系化电子信息装备试验评估中存在的困难，以一体化指挥信息系统这一典型电子信息装备为研究对象，依据“OODA”环基本理论，分析了信息在指挥信息系统中的传递过程，进而得到指挥信息系统OODA控制环路的本质内涵；从复杂系统角度，研究了一体化指挥信息系统的复杂性特点；结合一体化指挥信息系统自身的独特特征，剖析了基于还原论的性能试验方法在体系化电子信息装备试验问题分解时的根本困难；为解决此难题，基于系统论的综合集成方法，从方法论上提出一种用于指挥信息系统试验问题分解的方法，以一体化防空指挥信息系统抗干扰指标体系构建为例说明了该方法在试验问题分解方面的应用过程，表明了该方法在体系化电子信息装备试验评估问题分解中的有效性。

There is great difficulty in solving systematic electronic equipment testing assessment for reductionism. Taking the typical integrative command information system for example, the information transmission process is analyzed based on the OODA loop theory, and the essential connotation of the command information system is also derived. From the perspective of complex system, the complexity of the integrative command information system is studied. Through analyzing the complexity with the unique traits of the integrative command information system, it can be concluded that there is essential difficulty of problem decomposition by custom performance testing method in systematic electronic equipment test, and the reason is that the performance testing method conforms to reductionism. To solve this difficulty, a methodology for problem decomposition is put forward based on systematology meta-synthesis method, and it is used in command and control system test assessment. An example of constructing anti-interference indexes system is given for the integrative air defense command information system. The example has illustrated the application process of the decomposition method and demonstrated that the method is of great value in effectiveness evaluation of system of systems combat test for electronic information equipment.
