Methods of conception soft-and operation in cloud model
云模型中的概念软与求解方法

On account of the importance of the conception soft-and operation in the cloud models as artificial intelligence with uncertainty, two soft-and operation methods to compute the conception were introduced, namely, projection mapping and neural network soft-and. The drops created by cloud models were mapped to new universe of discourse and immediately the X-term cloud generation was used to gain the results of soft-and by the former method. In the later method, case based reasoning was combined with neural network, and through training and learning, the certainty level was predicted finally. The experiments testify that the two conception soft-and methods provide valid and fixed ways for executing the conception of soft-and operation.
