Abstract

High-risk industrial environments have continued to experience elevated workplace injuries, in part because traditional manual safety assessments still face major drawbacks related to subjectivity, limited scalability, and difficulty adapting to complex and changing environmental contexts. The primary objective of this research is to systematically investigate and address critical gaps in feasibility, scalability, contextual enhancement, and adaptive intelligence for computer vision-based safety and ergonomic risk assessment across high-risk industrial environments. The research methodology follows a systematic four-phase process, each contributing critically to the overall objective. Phase one establishes computer vision feasibility for personal protective equipment detection in steel manufacturing environments using labeled image datasets and cross-validation techniques. Phase two develops an integrated unmanned aerial vehicle (UAV)-based computer vision framework using pose estimation algorithms for automated ergonomic risk assessment, validated through construction site deployment. Phase three creates the Elevated Construction Ergonomic Risk Index (ECERI) using multi-tier validation methodology, including theoretical proofs, computational simulations, and empirical expert judgment comparisons to enhance traditional Rapid Entire Body Assessment (REBA) with environmental context factors. Phase four implements the Self-Organizing Fuzzy Inference System (SOFIS) incorporating dual uncertainty quantification through information-theoretic frameworks and Monte Carlo methods with expert-in-the-loop validation. The research demonstrates successful computer vision implementation in challenging industrial environments, validates scalable UAV frameworks for comprehensive ergonomic monitoring, establishes context-aware assessment methods improving traditional approaches, and creates adaptive intelligent systems with uncertainty awareness and continuous learning capabilities. These findings provide validated solutions addressing each identified gap in current safety monitoring approaches, contributing practical tools and theoretical advancement for improved occupational safety monitoring systems across high-risk industries.

Descriptive scope: 4 PCTA

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
