Failure mode effects and criticality analysis (FMECA) is a commonly adopted approach to defining, assessing, reducing possible failures in designs, systems, processes, products, services. Traditional FMECA ranks the failure modes of products based on risk priority number (RPN), which obtained by multiplying elements. Conventional has shortcomings badly handling unknown information unreasonably ...

In this paper we consider linguistic information aggregation problems where a prioritization relationship exists over attributes. The authors define a prioritized 2-tuple ordered weighted averaging (PTOWA) operator to aggregate satisfactions of alternatives under attributes with a linear prioritized ordering. The authors then use the PTOWA and a TOWA operator to aggregate linguistic information...

Nowadays, the patients and physicians use the health-related websites as an important information source and, therefore, it is critical the quality evaluation of healthrelated websites. The quality assessment of health-related websites becomes especially relevant because their use imply the existence of a wide range of threats which can affect people’s health. Additionally, website quality eval...

There are many situations in which problems deal with vague and imprecise information. In such cases, the information could be modelled by means of numbers, however, it doesn’t seem logical to model imprecise information in a precise way. Therefore, the use of linguistic modelling have been used with successful results in these problems. The use of linguistic information involves the need of ca...

In this paper, the multiple attribute decision making (MADM) problems are investigated with picture 2-tuple linguistic information. Then, based on Hamy mean (HM) operator and dual (DHM) operator, power average geometric operations utilized to develop some aggregation operators: weighted (P2TLPWHM) (P2TLPWDHM) ordered (P2TLPOWHM) (P2TLPOWDHM) hybrid (P2TLPHHM) (P2TLPHDHM) operator. The prominent...
