Study on Grey Characteristic of Electronic Equipment Test System

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.
