We introduce a new approach to study the practical stability of hybrid fuzzy systems on time scales in the Lyapunov sense. Our method is based on the delta-Hukuhara derivative for fuzzy valued functions and allow us to obtain new interesting stability criteria. We also show the validity of the results of [M. Sambandham: Hybrid fuzzy systems on time scales, Dynam. Systems Appl. 12 (2003), no. 1-2, 217-227], by embedding the space of all fuzzy subsets into a suitable Banach space.Comment: This is a preprint of a paper whose final and definite form is published in Applicable Analysis and Discrete Mathematics (AADM), ISSN 1452-8630 (printed), ISSN 2406-100X (online), available online at [http://pefmath.etf.rs].
