【摘要】 正态云模型是一种最基本的云模型,用于定性概念与定量描述之间的不确定性转换.根据实际定性概念的含义,可扩展为三角云、半正态云和正态组合云.将云模型的数字特征期望理解为函数或图形,提出函数云、分形云等扩展云模型.给出各种扩展云模型的云发生器算法,有效地扩大地云模型的应用场合.更多还原

【Abstract】 The normal cloud was the most important kind of cloud model,which was used to establish transformation of uncertainty between the qualitative concept and the quantitative description.Based on the actual characteristics of the qualitative concept,we could extend different kinds of clouds,for example,the triangle cloud,the half cloud model,and the combined cloud model.We understood digital characteristics expectation of cloud model for the function or graphics and provided a variety of extended clouds such as the function cloud and the fractal cloud.Then the detailed generator algorithms of the extended cloud models were given which expanded the applications of the cloud model.更多还原
