A Method of Multi-Attribute Synthetic Evaluation Based on Cloud Model

The evaluation progress using the cloud model executes the transform between the qualitative object and ration and makes the evaluation model get more persuasion and to be more easily suitable. By using the cloud model, this paper maps the indefinite comment as different cloud droplets with fine variations, and maps the variation of each factor’s weight as correctable mathematic expectation of the cloud, and thus puts forward a comprehensive evaluation model based on cloud model. Simulation results show that: The new model also can give us a set of evaluation of the different factors impersonally and the content distinguishes from the traditional ways.
