Trust and opinion information in intuitionistic fuzzy environments

A high-efficiency energy storage battery technology development project was officially launched, attracting seven experts from different institutions to participate and form a high-efficiency energy storage battery R&D collaboration network. Based on the participants' previous project collaboration experience, three overlapping subgroups naturally formed in the network. After the research and development are completed, the nine members must jointly evaluate the most suitable TT path for the energy storage battery technology.
