Calculation formulas and correlation inequalities for variance bounds and semi-variances of fuzzy intervals

Variance in fuzzy set theory, generally applied in investment decision, risk evaluation, and so on, can be described as a measurement that gauges the deviation of a fuzzy number. In this paper, in order to extend the application range and enrich the research area of variance, the concepts of varianc...
