The paper introduces generalized trapezoidal fuzzy number to describe risk rate,which adds a degree of confidence of estimator s opinion.

Study on application of the method of determining index weights based on trapezoidal fuzzy numbers

This paper introduces a F-AHP which is based on its trapezoidal fuzzy numbers.

A kind of uncertain multi-attribute decision-making problems is studied,in which the information about the attribute weights is completely unknown and the attribute values are in the forms of trapezoidal fuzzy numbers.

Composite evaluatiln of engineering with trapezoidal fuzzy number languistic index;

On priority of trapezoidal fuzzy number complementary judgment matrix based on two-tuple linguistic;

Fault tree analysis of oil and gas pipe-lines with trapezoidal fuzzy number

The concurrent multimachine scheduling of fuzzy job time being trapezoid fuzzy number;

Reliability of GIS product based on trapezoid fuzzy number;

Solution to linear programming with trapezoid fuzzy numbers in restricted condition;

Center of gravity (COG) of generalized fuzzy numbers is calculated with simple center of gravity method (SCGM) and a new fuzzy risk analysis method based on similarity measures of generalized fuzzy numbers is proposed, which considers the confidence level of ideas from decision makers and uncertain risk influence factors.
