Abstract:According to uncertainty and complexity of decision-making of enterprise’s technology innovation projects,a decision-making analysis method is proposed which is called Interval Valued Intuitionistic Fuzzy Set with Entropy Weight.The main idea of the method is to determine attribute weights by cross-decision information entropy and entropy theory.Combine attribute weights and decision-makers weights with interval intuitionistic fuzzy matrix after normalization to obtain comprehensive decision information value.Then calculate and compare the size of score function value to select the optimal project. Last, the results indicate that the method is feasible and practical, so its theory can be provided as a theoretical reference for enterprise’s technology innovation projects.
