摘要：The distance measures of similarity between vague sets (values) have been developed tosolve the problem of slagging characteristic of coal ash, and a slag-prediction model of coal ashbased on vague sets was proposed. In the model, four single indices and their bounds are involved.The indices are ST, SiO2/Al2O3, B/A and G. At the same time, 25 coal ashes were selected assamples. The model was employed to predict the slagging characteristic of the 10 coal ashes.Through predicting, determining and comparison, it proved that the accuracy of the patternrecognition model was 90 percent and met the engineering requirements. So the model built wasreasonable and feasible. © (2013) Trans Tech Publications, Switzerland.
