These days, the appraisal of COVID-19 vulnerability has become a difficult errand for whole world. The administration dynamic issue frequently includes numerous elective arrangements clashing standards. In this paper, we present multi-criteria decision-making (MCDM) procedure based on fuzzy VIKOR method to survey in state Assam, India. trapezoidal number is utilized evaluate rating loads set-up...

Interval number is a useful tool to handle the uncertainty brought by human factors in multi-criteria decision-making (MCDM) process. When faced with MCDM problems in real-world, the experts may be uncomfortable giving precise upper and lower bounds of the interval ratios on multi-criteria. Based on the reciprocal judgment matrices given by the experts through pairwise comparisons, the satisfac...

Vertical handover mechanism is an important issue in heterogeneous wireless networks. Continuity of service during handover and QoS are relevant issues to deal with. This paper focuses on vertical handover decision making. It proposes a Rank Average method for the best access network selection. This method is an aggregation of two Multi Attributes Decision Making (MADM) methods: Technique for O...

Joint Admission Control (JAC) handles the admis-sion of all new or handoff service requests in the mod-ern heterogeneous networks and allocates the required resources and guarantees the QoS constraints for the service. JAC is a multicriteria problem in nature, and the usage of MCDM system is mandatory to decrease the influence of the dissimilar, imprecise, and contra-dictory measurements for th...

Purpose – Firms operating in the service sector must have a dynamic structure to be competitive in a volatile business environment. The dynamic structure brings skilled employees and talented managers together to create effective strategies for global competition. In traditional retail service companies, the majority of the staff interacts intensively with the clients and engaged in advanced fa...

Generalized trapezoidal fuzzy numbers (GTFNs) have been widely applied in uncertain decision-making problems. The similarity between GTFNs plays an important part in solving such problems, while there are some limitations in existing similarity measure methods. Thus, based on the cosine similarity, a novel similarity measure of GTFNs is developed which is combined with the concepts of geometric...

In the context of Chinese innovation-driven strategy, role suppliers has been attracting much attention. Since not every supplier can contribute to buyer’s innovation, scientifically selecting an innovative is highly valued by decision-makers from new energy vehicle (NEV) manufacturers. This paper focuses on proposing a novel decision framework in collaborative which helps NEV manufacturers sel...
