Single valued neutrosophic hesitant fuzzy set has three independent parts, namely the truth membership hesitancy function, indeterminacy membership hesitancy function, and falsity membership hesitancy function, which are in the form of sets that assume values in the unit interval [0, 1]. Single valued neutrosophic hesitant fuzzy set is considered as a powerful tool to express uncertain, incompl...

assessment of risks is a key task in the project management. in this process, risk breakdown structure (rbs) approach can be utilized to identify project relevant risks. in the previous classical method, only limited number of attributes is considered in the evaluation that can cause unreliable results. in this paper, an attempt has been made to introduce and involve a relatively comprehensive ...

The multi-attribute decision-making methods allow to solve arbitrary problems governed by several parameters. In this paper, the choice of a composite material was analyzed, by considering the availability from four companies. The multi-attribute decision Analytic Hierarchy Process (AHP) procedure was used to select the best levels for different attributes, both parametric and non-parametric, a...

Based on grey language multi-attribute group decision making, a kernel and grey scale scoring function is put forward according to the definition of grey language and the meaning of the kernel and grey scale. The function introduces grey scale into the decision-making method to avoid information distortion. This method is applied to the grey language hesitant fuzzy group decision making, and th...

Interesting insights into uncertain multi-attribute decision-making systems have come from the theory of hesitant fuzzy sets. Outputs become more reliable when a decision-maker is not forced to produce one single assessment in presence hesitation. Hesitancy environments grants flexibility decision-maker, therefore enhancing validity all subsequent results. Due these facts, hesitation has landma...
