Fuzzy synthetic evaluation on variable weight of investment risk in road project

There are lots of investment risks in road project,but the common method is to conduct qualitative and partial evaluation for the risks.On the principle of systematic evaluation,risk analysis system and risk index are set up,fuzzy consistent matrix is introduced to calculate basic weight,partial variable weight with the combination of penalty-incentive is put forward to calculate variable weight,and fuzzyAHP method is adopted to analyze the investment risks in road project.The feasibility of the method is verified in the experiment and engineering.
