The researchers developed a method called the real Shapley value for evidential games with fuzzy characteristic function to help with decision-making in games. This method uses level sets and basic probability assignments to find the real evidential Shapley value. By applying this method, they were able to effectively solve expert decision-making problems in uncertain environments. The experiments showed that the proposed model successfully determined the real evidential Shapley value for given evidential games, demonstrating its usefulness in addressing decision-making challenges.
