in this paper, we present a revised similarity measure based onchen-and-chen's similarity measure for fuzzy risk analysis. the revisedsimilarity measure uses the corrected formulae to calculate the centre ofgravity points, therefore it is more  effective than the chen-and-chen'smethod. the revised similarity measure can overcome the drawbacks of theexisting methods. we have also proposed a new ...

China has become a global leader in green infrastructure finance, investing heavily renewable energy, sustainable transportation, and buildings. However, there are multiple risks challenges that impede the development of finance. Thus, this study analyzes prioritizes associated with finance proposes policy plans to mitigate these risks. A Fuzzy analytical hierarchy process (AHP) is used identif...

The hesitant fuzzy soft set (HFSS), as a combination of hesitant fuzzy and soft sets, is regarded as a useful tool for dealing with the uncertainty and ambiguity of real-world problems. In HFSSs, each element is defined in terms of several parameters with arbitrary membership degrees. In addition, distance and similarity measures are considered as the important tools in different areas such as ...

recommender systems (rs) provide personalized recommendation according to user need by analyzing behavior of users and gathering their information. one of the algorithms used in recommender systems is user-based collaborative filtering (cf) method. the idea is that if users have similar preferences in the past, they will probably have similar preferences in the future. the important part of col...

Abstract This author introduces the concept of Stepwise Strategy Approach (SSA) for dealing with a number of problems arises in the current age of technology. This new idea is combined with the knowledge of Grey Theory for adding flexibility to decision making process. Grey theory is useful for grasping the ambiguity exists in the utilized information and the fuzziness appears in the human judg...

Airline companies today face formidable competitive pressure. To confront these problems and sustain competitive advantages, many companies have resorted to downsizing; this method, however, often results in the overworking of a small number of workers, especially in the case of aircraft maintenance staff, who are largely responsible for aviation safety. At the same time, during the staff annua...
