Abstract :
Establishment of index system plays a crucial role in the course of uncertain information system evaluation. However, there is not a quantitative means on the problem of constructing the index system for uncertain information system. In order to solve these problems, a novel synthetic algorithm is put forward based on fuzzy set theory and grey relation analysis in this paper. Fuzzy membership degree is used to ascertain the importance of index by using of fuzzy set theory. At the same time, grey relation matrix is used to analysis the relativity of index. Moreover, the rationality and the dependability of index system are validated by using of validity coefficient and dependability coefficient. On base of it, the model of index selection is set up and applied in the index selection of alarm window on main control room of the nuclear power plant. Results of the case study prove that the proposed method is reasonable and feasible.
