摘要:With the development of computer and network technology, more and more areas (such as power system security control, medical diagnosis system, government emergency management, stock invesment strategy anallysis, etc.) have gradually established decision-making support systems, which are mainly responsible for information collection, management and analysis. Studies show that decision-making support systems have greatly enhanced user productivity. So the engineers’ interest in designing computerized decision support systems has considerably increased in recent years. The current decision support systems mainly focus on data acquisition and analysis. They are responsible for providing large amounts of data continuously and delivering adaptable models, which can enable people to use these results effectively and then make decisions more quickly and accurately. Then, is there any real-time decision support system in the future that can change human’s judgment and decision-making? By behavior science research, this paper will provide some answers by presenting the results of a study that subliminal vision signal may have direct influence on human’s advanced cognitive process and finally change human’s decision under ambiguity. It will provide key technology and new research ideas for engineers to design more intelligent and more powerful decision-making support systems in the future.
