Real-world information is often characterized by fuzziness due to the uncertainty. Z- numbers is an ordered pair of fuzzy numbers and is widely used as a ﬂexible and efﬁcient model to deal with the fuzziness information. This paper extends the fuzziness measure to continuous fuzzy number. Then, a new fuzziness measure of discrete Z-numbers and continuous Z-numbers is proposed: simple addition of fuzziness measures of two fuzzy numbers of a Z-number. It can be used to obtain a fused Z-number with the best in- formation quality in sensor fusion applications based on Z-numbers. Some numerical examples and the application in sensor fusion are illustrated to show the efﬁciency of the proposed fuzziness measure of Z-numbers.
