Control measure prioritization in Fine - Kinney-based risk assessment: a Bayesian BWM-Fuzzy VIKOR combined approach in an oil station
Özet
The Fine - Kinney is a risk assessment method widely used in many industries due to its ease of use and quantitative risk
evaluation. As in other methods, it is a method that recommends taking a series of control measures for operational safety.
However, it is not always possible to implement control measures based on the determined priorities of the risks. It is
considered that determining the priorities of these measures depends on many criteria such as applicability, functionality,
performance, and integrity. Therefore, this study has studied the prioritization of control measures in Fine − Kinney-based
risk assessment. The criteria affecting the prioritization of control measures are hierarchically structured, and the importance
weights of the criteria are determined by the Bayesian Best–Worst Method (BBWM). The priorities of control measures were
determined with the fuzzy VlseKriterijumska Optimizacija I Kompromisno Resenje (FVIKOR) method. The proposed model
has been applied to the risk assessment process in a petrol station’s liquid fuel tank area. According to the results obtained
with BBWM, the most important criterion affecting the prioritization of control measures is the applicability criterion. It
has an importance weight of about 42%. It is followed by performance with 31%, functionality with 18%, and integrity with
10%, respectively. FVIKOR results show that the “Periodic control of the ventilation device” measure is the top priority for
Fine − Kinney risk assessment. “The absence of any ducts or sewer pits that may cause gas accumulation in the tank area
and near the dispenser; Yellow line marking of entry and exit and vehicle roads; Placing of speed limit warning signs” has
been determined as a secondary priority. On conclusion, this proposed model is expected to bring a new perspective to the
work of occupational health and safety analysts, since the priority suggested by Fine − Kinney risk analysis methods is not
always in the same order as the one in the stage of taking action, and the source, budget, and cost/benefit ratio of the measure
affect this situation in practice.
