Uncertainty analysis on a construction project when evaluating Fushun activated alumina, used data mostly from forecasts and estimates. Due to the limited nature of data and information, activated alumina, the actual situation in the future and this may differ, which will bring the risk of investment decision. In order to avoid or minimize the risk, we must analyze the impact of uncertainty on the project economic evaluation of highly active alumina, activated alumina plant to determine the reliability of the project, which is the uncertainty analysis. According to the analysis of different content and focus on faces, uncertainty analysis can be divided into break-even analysis, sensitivity analysis and probabilistic analysis. In the feasibility study, the breakeven level generally performed analysis, sensitivity analysis and probability distribution, visualization project circumstances.
