Fuzzy AHP in Safety Assessment
Research Guide
What is Fuzzy AHP in Safety Assessment?
Fuzzy AHP in Safety Assessment applies fuzzy Analytic Hierarchy Process to manage linguistic uncertainty in multi-criteria safety risk evaluations for industries like mining, energy, and construction.
This method extends traditional AHP by incorporating triangular fuzzy numbers to capture imprecise expert judgments in pairwise comparisons. It has been used in coal mine safety (Wang et al., 2016, 123 citations), power transformer risk (Zhou et al., 2022, 66 citations), and occupational health in mining (Bao et al., 2017, 47 citations). Over 20 papers from 2009-2023 demonstrate hybrid models combining Fuzzy AHP with FMEA or FCE.
Why It Matters
Fuzzy AHP enables robust prioritization of safety hazards in high-stakes environments with vague data, such as coal mine evaluations where Wang et al. (2016) ranked risk factors to guide interventions. In power systems, Zhou et al. (2022) applied it within hesitant fuzzy FMEA to identify critical transformer failures, reducing outage risks. Zhao and Li (2015) used a cloud-enhanced version for UHV project sustainability, informing multi-billion-dollar investments.
Key Research Challenges
Handling Expert Inconsistency
Fuzzy pairwise matrices often yield inconsistent judgments, requiring aggregation methods like least squares (Wu et al., 2012). Improved consistency ratios remain challenging in group settings (Sharp, 2009). This affects reliability in safety-critical decisions.
Defuzzification Sensitivity
Converting fuzzy weights to crisp values introduces bias depending on methods like centroid or geometric mean. Zhou et al. (2022) highlight sensitivity in hesitant fuzzy environments for transformer risk. Standardization lacks across safety domains.
Scalability to Large Hierarchies
Complex safety assessments with many sub-criteria lead to judgment fatigue and matrix explosion. Bao et al. (2017) combined FMEA with improved AHP for mining but noted computational limits. Hybrid integrations with PSO-SVM (Liu et al., 2020) seek remedies.
