Calculating inverse functions of fuzzy numbers Original Research Article

This paper discusses the calculation of inverse functions of fuzzy numbers. In our previous work [1], we have given a general method for calculating functions of fuzzy numbers. This paper can be viewed as the extension of [1]. It proves necessary and sufficient conditions for solution of such inverse functions, and a step-by-step testing method which can be used for calculating any continuous and bounded inverse functions of fuzzy numbers is given.
