GU Zhi-peng · Jisuanji gongcheng yu sheji · 2008
Cloud model is an effective tool in uncertain transforming between qualitative concepts and their quantitative expressions.The normal-cloud model is extensively studied presently and the research on trapezium cloud-model is less.Compared to the normal-cloud model,trapezium-cloud model has extensive exist in everyday life and own merits to represent numerical concept;Some related definitions of trapezium-cloud are given,and the new methods of cloud transform and soft-or operation that has combine with trapezium-cloud model are proposed,based on the analyse of the existing method of conception division and conception exaltation in cloud theory.These methods provide the base to solve some key problems in data mining.
