Aiming at fuzziness of water-saving irrigation technology evaluation and the independence and incompatibility of each single index, a entropy-weight based fuzzy matter-element model for paddy field water-saving irrigation technology optimization was established based on the combination of fuzzy matter-element and the entropy theory in paddy field water-saving irrigation technology evaluation in the...
The study on decision making is of important guide for theory and practice. Based on the theories of fuzzy recognition, the pattern of multiple objects and multiple dimensional grey-fuzzy decision making with self feedback is presented in this paper. Firstly, according to the given weights, weighting integrated value of decision making is computed. Secondly, the method of fuzzy recognition with single...
The core of fuzzy evaluation on the operational performance of e-commerce websites is membership degree transformation. But the existing transformation methods should be questioned, because redundant data in index membership degree is also used to compute object membership degree, which is not useful for object classification. The new algorithm is: using data mining technology based on entropy to...
In order to realize evaluation of oil storage safety, clear the redundant data in indexes membership which is not useful for goal classification, based on data mining of entropy, mining knowledge information about object classification hidden in every index, affirming the relation of object classification and index membership, eliminating the redundant data in index membership for object classification...
The core of project risk fuzzy evaluation is membership transformation, but the transformation algorithm includes redundancy that is useless for classification. In order to overcome the redundancy, we can excavate the information of the object classification hided in index membership to define the divisional right by the method of data excavation based on entropy, delete redundant index membership...
In order to overcome the subjective limitation in traditional fuzzy comprehensive evaluation model, a new model based on entropy weight is proposed for evaluating software dependability, and using the entropy weight coefficient method modifies the weight in it. The model reduces the subjective influence, and enhances the evaluation results objectivity. It provides an effective method for software...
To enhance security in distribute networks, it is necessary to evaluate trustworthiness of service and help selecting a proper supplier. Many probabilistic trust models have been developed, such as Beta distribution for single dimensional trust model, Dirichlet distribution for multi-dimensional trust model. But most of them are based on certain probability distribution, which are not always accurate...
