Abstract
Cognitive testability is an inherent attribute of the modern electronic equipment. The information acquisition ability of cognitive testability was described in details and an evaluation model was built upon the basic construction of the index system of the cognitive testability. First of all, the idea and contents of the information acquisition ability of the modern electronic equipment was stated. Second, based on this, a mathematical model of weight calculation with the use of entropy weight method was built. The innovation and characteristic of this paper lie in the detailed explanation of information acquisition ability and the building of the evaluation model.
