基于复杂系统的基本理论，研究了体系的概念、内涵及典型实例。根据体系对抗及体系对抗试验作为复杂系统的表现和特点，从非线性、涌现性这两个主要方面分析了体系对抗试验的复杂性。剖析了传统性能试验方法的特点，根据这些特点总结得出性能试验方法不能适应体系对抗条件的试验，其根本原因在于性能试验方法所遵循的还原论思想不适用于体系对抗试验的复杂性；接着，着重从方法论方面分析了性能试验方法在体系对抗条件下的不足之处，进而针对这些不足之处得到了应该从复杂系统角度研究适用于体系对抗试验的方法论等结论。

In the perspective of systematology, it is a complex system to solve the problem of system of systems (SoS) combat test. The concept and connotation of SoS were studied based on the basic theory of complex system, and a typical example of SoS was illustrated. On the basis of the demonstration and trait of complex system of SoS combat and SoS combat test, the complexity of SoS combat test was analyzed on two important items including non-linearity and emergency. Through analyzing the basic traits of custom performance test method, it was summarized that performance test method cannot adapt to SoS combat test from these traits, and the fundamental cause was that the reductionism did not adapt to the complexity of SoS combat test. The deficiency of performance test method was analyzed on methodology emphatically under the condition of SoS combat. Aiming at the deficiency of the performance test method on methodology, it was concluded that the methodology should be studied from the perspective of complex system in order to adapt to SoS combat test.
