A simple combined projection method for conservative decision-making

Abstract Machine learning and artificial intelligence based techniques have brought great convenience to human life but along with a series of algorithmic “black box”, discrimination ethical issues. One the solutions is integrate machine like expert evaluation research multi-attribute decision-making where “human brain intelligence” used for support “artificial intelligence”. In this article, we proposed new effective method evaluate rank alternatives in decision-making. Different from many existing approaches, employs both projection lengths angles make decisions. It supports psychological desirableness decision makers uses Relu function further enhance output qualities. This very simple construct applicable much wider situations than similar methods.
