Abstract 摘要
We define a class of fuzzy numbers which is uniquely identified by their membership functions. The function space will be constructed by combining a nonlinear mapping from [0,1] to and a class of probability density functions p from to [0,1]. Under our assumptions, we prove that there always exists a nonlinear mapping to fulfill the observed outcome. As an example, we define the operational laws in the function space when the probability density function is given by the Gaussian kernel. Especially, the common L-R number can be interpreted by and the addition can be seen as the operation on the expectation of the probability density function. One numerical example is provided to illustrate the proposed approach.
