Generalized hesitant trapezoidal fuzzy number whose membership degrees are expressed
by several possible trapezoidal fuzzy numbers, is more adequate or sufficient to solve real …

In this paper, the concept of trapezoidal fuzzy multi-number (TFM-number) is proposed and
some desired operational laws with properties are introduced. In the TFM-number, the …

In this paper, the Inner–Outer Direct Search (IODS) optimization technique is extended in the
fuzzy environment to solve a fuzzy system of nonlinear equations. The proposed approach …

In this paper, we propose a method to solve multi-criteria decision-making problems using
trapezoidal fuzzy multi-numbers. Therefore, we first proposed the concept of value and …

The urban mobility system is an important factor in social development and must, therefore,
be tackled in a way that enables balanced, sustainable development. The purpose of the …
