电子装备试验系统的灰色特性研究

Study on Grey Characteristic of Electronic Equipment Test System

电子装备试验中存在很多信息不完全、不确定及数据少等不确定性决策问题,灰色系统理论是解决这种“贫信息”问题的有力工具。该文首先总结了电子装备试验系统的组成、传统意义下的试验系统特性;进而从系统的角度,提出了试验系统具有结构灰性、关系灰性、模型灰性、认知灰性等灰色特征;最后研究了试验数据的不确定性来源及其灰色表现形式,并给出了试验数据的不确定性度量和系统不确定性的平均度量数学模型。研究结论可为扩展利用灰色系统理论分析解决电子装备试验系统中的各种不确定性问题提供理论支撑。

There are many uncertain decision-making questions, in which the information is incomplete and vague, in the electronic equipment test system. The grey system theory is a powerful tool to settle the kind question. The component of the electronic equipment test system and its characteristic in the traditional sense are summarized firstly. Then from the view of system, the grey characteristics, including structure grey, relation grey, model grey and cognition grey, of the electronic equipment test system are proposed. Finally, the source and the grey model of uncertain information in electronic equipment tests are studied. The uncertainty measurement model of the test datum and the average uncertainty measurement model of the system are introduced. The research conclusions can offer theoretic supports for the increasing application of the grey system theory to the domain of the electronic equipment test system.
