Navigational Environmental Risk Evaluation of Breakwater Based on the Analytic Hierarchy Process

This paper introduces the analytic hierarchy process, and applies in the process of engineering project risk evaluation of navigational environment safety. This paper takes the breakwater project of a harbor as an example for analysis, through the recognition of each risk source and risk factor that the project influences on navigation safety to determine the risk indicators, and uses analytic hierarchy process to analyze the impact of various risk factors on navigation safety, thus gains the overall influence of project on navigation safety. This can be used as an auxiliary tool of engineering risk management.
