影响和决定电子对抗装备(以下简称装备)发展的行为变量之间存在着各种复杂的相互关系,由这些行为变量及其相互关系构成的装备发展系统呈现出明显的非线性、非结构性、因果性和多重反馈性;而且系统中的人流、物流、能量流和信息流等,有的可以量化,有的则很难量化。所有这些特性给装备发展系统的分析提出了新的研究课题或是新的难度。 There are various complex interrelations between the behavioral variables that influence and decide the development of electronic countermeasures equipment (hereinafter referred to as equipment). The equipment development system composed of these behavioral variables and their interdependence shows obvious nonlinear, unstructured, Causality and multiple feedback; and the system of people flow, logistics, energy flow and information flow, etc., some can be quantified, while others are difficult to quantify. All of these features present a new research topic or new difficulty to the analysis of equipment development systems.
