Abstract EN
The South-to-North Water Diversion Project consists of long-distance water delivery channels and a complicated geological environment along the way.
To deal with the operation safety of the water conveyance channels in the middle route of the South-to-North Water Diversion Project, this study analyzes six failure modes: structural cracks, poor water delivery during ice periods, instability of canal slopes, material aging, abnormal leakage, and foundation defects.
Based on FMEA, a multigranularity language evaluation method that can be converted into interval intuitionistic fuzzy numbers is used to evaluate the severity (S), occurrence (O), and detection difficulty (D) of the six failure modes.
Interval intuitionistic fuzzy entropy is used to calculate the weights of the risk factors.
Finally, a ranking model of each failure mode is built based on the TODIM method.
The final ranking results show that the risk of abnormal leakage is the largest, and the risk of poor water delivery during ice periods is the smallest.
The feasibility and validity of the calculation results are verified by comparing them with the ranking results of the traditional RPN and TOPSIS methods.
The TODIM-FMEA risk assessment model offers a new solution to the problem of risk assessment for water transfer projects.
