Abstract

This research utilized an Adaptive Neuro-Fuzzy Inference System (ANFIS) integrated with Partial Least Squares (PLS) structural modeling to evaluate perceived workplace safety, defined as employees' willingness to adhere to safety regulations. A survey methodology was employed, measuring six key components: tacit safety knowledge, explicit safety knowledge, psychological safety attitude, emotional safety attitude, behavioral safety culture, and psychological safety culture. The study was conducted with 90 employees from Sarkhun and Qeshm Gas Refining Company. Data analysis was performed using SPSS, Smart-PLS, and MATLAB software. Findings revealed that all six identified factors significantly impact perceived safety. Additionally, the ANFIS modeling results specifically demonstrated that behavioral safety culture is the most crucial predictor of an employee's perceived safety in the workplace, highlighting its paramount importance. This research utilized an Adaptive Neuro-Fuzzy Inference System (ANFIS) integrated with Partial Least Squares (PLS) structural modeling to evaluate perceived workplace safety, defined as employees' willingness to adhere
