q-Rung Orthopair Fuzzy Approach for Multiple-Attribute Group Decision-Making and Application to Commercial Computer Network Security Evaluation

Nowadays, with the increasing use of computer network technology in various fields, coupled with the openness of the Internet, computer networks are facing various information security issues, which will have a very important impact on their applications. Both enterprises and individuals may cause significant economic losses due to these problems, so certain measures need to be taken to protect the information security of computer networks. The commercial computer network security (CCNS) evaluation is MAGDM. In this research, based on projection measure (PROJM) and bidirectional projection measure (BPROJM), some forms of projection measure with q-rung orthopair fuzzy sets (q-ROFSs) are depicted. Then, two weighed projection approaches are depicted to put forward the MAGDM. Lastly, numerical examples for CCNS evaluation and different comparative analysis is employed to verify the developed approaches.
