An Approach of Quality Performance Assessment Based on Cloud Model

Abstract:

The criteria of GB/T 19580 are listed in form of linguistic term and its scoring system lacks of interim between adjacent grades. When the criteria are used in quality performance assessment, it will deal with large of qualitative indicators’ measurement and synthesis. The linguistic cloud model is introduced to implement the transition between qualitative criteria and quantitative measurement, and the evaluation approach of cloud center gravity is used to measure the change of multi-dimensional synthetic cloud. The degree of deviation θ is used to weigh the deflection between actual quality performance and best practice. Finally, a case is discussed to demonstrate the method proposed in this paper.
