Abstract

In order to solve the problems of fuzziness and uncertainty in the identification of risk factors in the operation of hydropower engineering, a risk assessment model based on SPA-Cloud model was established. Firstly, this paper sorted out the main risk indicators in the operation of the project, established an index system of risk assessment consisting of 4 primary indexes(personnel, management, operating environment and project risks)and 13 secondary indexes, and used uncertain analytic hierarchy process to determine fuzzy weights interval. Then,the set pair analysis method was adopted to refine the weight interval, and using the cloud model to determine the operational risk level of the hydropower engineering. Finally,according to an actual running hydropower engineering, the feasibility and effectiveness of the model in project operation risk assessment was proved.

Key words

hydraulic engineering / uncertain AHP / set pair analysis / cloud model / operational risk
