Therefore, further, thoroughly studies the enterprise human capital investment risk related theory is of great theoretical significance and practical significance. In this paper, we investigate the group decision making problems for evaluating the risk early-warning for enterprises investment project based on the grey relational analysis model with interval-valued intuitionistic fuzzy information. A modified GRA analysis method is proposed. Then, based on the traditional concept of GRA method, calculation steps for solving interval-valued intuitionistic fuzzy group decision-making problems are given. Finally, an illustrative example for evaluating the risk early-warning for enterprises investment project is given.
