Equipment Maintainability Qualitative Evaluation Based on Improved Cloud Barycenter Method
摘要
Abstract
The cloud barycenter method is introduced to the equipment maintainability qualitative evaluation. In the evaluation process of cloud barycenter method,it is necessary to map every qualitative evaluation term to a interval by which the term is transformed into a cloud model. Aiming at the shortcoming of entropy determination based on three-entropy rule,the intensity of membership degree of a cloud model is divided in the interval from expect value minus 3 entropies to expect value plus 3 entropies,and then the model of interval equal to four times of entropy is established. The method to compute the dispersion between the cloud barycenter location of single quantitative index and that of the ideality of the index is improved,and the model to compute the dispersion of integrated cloud is simplified. Finally the scientific nature and rationality of the improved method are validated by qualitative evaluation of some equipment maintainability.关键词
