In the paper, a scheme is proposed to predict whether the new employees could match their jobs or not, and discrete interval type-2 fuzzy set on time-varying universe is used for evaluating the experts' view of the employees' performance. The evaluation results are sent into a BP neural network to get the predicted value. Finally, the Markov model is(More)
It is not easy for fuzzy model to describe the uncertainty of language, because the fuzzy model is a conventional function. The membership function of type-2 fuzzy sets(T2 FS) combines a variety of possible type-1 membership, and the primary membership function reflects the impact of uncertain factors. Online reviews are perceptive informatics, and with the(More)
In the paper, the customer satisfaction index for power system is measured based on the characteristics of the power supply service quality. For the uncertainty of assessment, interval type-2 fuzzy set (IT2FS) is applied to evaluate it. The model of improving the power customer satisfaction is built and the corresponding linguistic dynamic orbits are given.(More)
