The expected value of a fuzzy number. (English) Zbl 0755.60004
Summary: The notions of expected interval and expected value of fuzzy number are introduced. The expected interval is defined as the expected value of an interval random set generated by the fuzzy number, and the expected value of this number is defined as the centre of the expected interval. The linearity of the expected interval is studied.
