"Cloud models are effective tools for uncertain transition between a linguistic term of a qualitative concept and its quantitative description. In short, it is a model of the uncertain transition between qualitatives and quantitatives."
Can you be more specific? Which qualitative concepts? and is it within the cloud domain ( as the resource management concepts )? or using the clouds as a tool to do the transition?
Sure someone does. Just see how many papers cite the original papers by Li Deyi. Google scholar finds over 200 such papers, though coming mostly from China and a few papers from Eastern Europe and, well, Iran. Since many papers that use cloud theory are written in a variety of the English language that is very difficult to understand, the concept is not widely known in Europe and the US. I myself struggle to understand it. Once I had to refuse to review a paper that used cloud theory precisely because it was close to totally incomprehensible.
