| Popis: | Comparing two or more fuzzy numbers and ordering them is an important topic in fuzzy theory. Z-number as a kind of fuzzy number that can effectively reflect the real world, after Zadeh proposed Z-number, the research on the ranking of Z-numbers has also received much attention. So the ranking of discrete Z-number is a necessary operation in Z-number arithmetic and has important practical significance. In this paper, we propose a new discrete Z-numbers ordering method. Our method is achieved by transforming discrete Z-number into common discrete fuzzy number and then comparing the magnitude of the transformed discrete fuzzy number. Finally, we present an example to illustrate this approach. |
