Safety risks are essential to the success or failure of the large-scale complex projects. In order to assess and evaluate the safety risks of the large-scale complex projects scientifically, a risk assessment method of work breakdown structure and risk breakdown structure (WBSRBS) is proposed to identify the project risks. In this paper, interval numbers are used to evaluate the risk levels, weights are assigned automatically based on the complexity and risk degree of WBS to distinguish three types of nodes in WBS, and a risk assessment algorithm is designed to assess safety risk at all layers of the project. A case study is conducted to demonstrate how to apply the method. The results show the practicality, robustness and efficiency of our new method, which can be applied to different kinds of large-scale complex projects in reality.
Key words:    large-scale complex project    risk assessment    WBS-RBS    assign weights automatically
