A risk ranking method based on intuitionistic fuzzy group decision-making model in the process of risk management in equipment projects

Focus on the risk management for the modern weapon equipment development projects, the intuitionistic fuzzy group decision-making ranking process is proposed in this paper to achieve a further risk ranking for the risks with the same risk exponent, making the ranking results more accurate and scientific. In this process, assessments are made on the risks´ occurring possibility and the consequences severity and a risk index system is established. The intuitionistic fuzzy set is used to indicate the experts´ assessments and the expert weight factor is involved in the process to make a different for each expert´s affection. Throughout the process, the TOPSIS is used to achieve the risk ranking. In the final part of this paper, we implemented this process to do the risk ranking for a project and proved that this model is available, scientific and rational.
