Qualitative investment decision-making methods under hesitant fuzzy environments (Q2315074)

This book has mainly analyzed five different hesitant fuzzy investment decision-making methods. They take the risk appetites into account, provide the optimal portfolios, improve the non-optimal alternatives, consider self-evaluation and peer-evaluation mechanisms, and make investment decisions under the extreme situations, respectively. Although these methods are different, they all have been constructed in the hesitant fuzzy environment and using the HFEs or the PHFEs.
