Fuzzy Stochastic Variable and Variational Principle
-
摘要: 从模糊事件的概率出发,定义了峰型模糊随机变量及其真值的期望概念。直接将参数的模糊随机性引入总势能泛函中,利用小参数摄动法建立了模糊随机变分原理。并阐明了它的应用。Abstract: In this paper the peaky fuzzy stochastic variable and its mean of real value were proposed besed on the concept of fuzzy probability.Fuzziness and randomness were introduced into the functional of overall potential energy.So the fuzzy stochastic variational principle and its application were presented by means of perturbation method.
