Abstract: WE ARE GLAD to be finally'answering Belton and Gear's concerns expressed in their article in Omega [l]. There are two points they make in their letter. The first has to do with rank reversal, and the second with how to ask the question by minimizing fuzziness. Our response is organized into four sections:(a) counterexample to the method proposed by Belton and Gear,(b) rank preservation,(c) legitimacy of rank reversal, and (d) how to ask the question.
Keywords: Rank reversal, Fuzzy, Rank preservation
