Abstract
Compared with the conventional power grid project, the UHV project construction faces more challenges and risks. Identifying the key risk indicators of UHV project construction can improve the level of project risk management and reduce risk-related loss. Taken the data missing of risk indicators into consideration, an improved rough set model for key risk indicators identification of UHV project construction is employed with the introduction of information content. Firstly, the information content of conditional attributes set and information significance of each conditional attribute are calculated; Secondly, the reduced core attribute matrix is formed; Then, the discernibility matrix is built; Finally, the final core attribute set is determined. After building the risk index system, the key risk indicators identification of a certain UHV project construction is performed. The calculation result shows that “land requisition and logging policy risk”, “project security management risk” and “land requisition, removing and crop compensation risk” are the key risk indicators.
