Research on Risk Assessment in Engineering Project Based on Route Analysis and Hierarchical Variable Weight Fuzzy Evaluation

The paper proposes the method of risk assessment based on route analysis and variable weight fuzzy evaluation. Firstly, it is on the basis of route analysis, and mines each stage and its critical factors of engineering project; and analyzes each uncertainly measuring with the method of fuzzy comprehensive evaluation; then solves the deferring characteristic of risk in engineering project using variable weight theory to improve the accuracy of risk evaluation. Finally, an example is used to prove the method is effective and practical.
