Abstract: In order to evaluate the subject behavior risk in construction phase of the complex construction project better, subject behavior risk factors were identified comprehensively for the construction phase, then an evaluation indicator system was established.These were based on the character of behavior risk and get from three dimensions-behavior subject, organizational behavior and project management goal.Weights of the factors were obtained by using the IFAHP method. Pieces of information on both the qualitative evaluation and the quantitative evaluation of the factors were assembled for the group decision making by using IFWA operators. Then a subject behavior risk evaluation model of IFAHP was built. Finally. The validity of the model was verified by running an example. The result shows that the model fully considers the uncertainty of behavior risk and the fuzziness of expert evaluation, and that the evaluation of the subject behavior risk by the model conforms with the actual situation.

Key words: complex construction project, intuitionistic fuzzy analytic hierarchy process (IFAHP), subject behavior risk, intuitionistic fuzzy weighted average (IFWA) operator, risk evaluation
