“…The general steps of MCDM include problem definition, objectives and criteria setting, alternatives design, criteria weighting, alternatives performance quantification, weights and performance integration, and final decision [45]. MCDM has been widely applied in the area of safety risk management to support well-informed priority decisions across different industries, mainly including the prioritization of risk factors [46][47][48] and risk mitigation strategies [49,50]. With a specific focus on OHS-related risk analysis, MCDM has been successfully adopted to provide risk ranking or priority, as OHS management involves multidisciplinary activity.…”

Ergonomic risks critically impact workers’ occupational health, safety, and productivity, and thereby the sustainability of a workforce. In the construction industry, the physical demands and dynamic environment exposes workers to various ergonomic hazards. While previous research has mainly focused on postural risks, there is a need to broaden the scope to include more relevant factors and assess them systematically. This study introduces a multi-criteria decision framework integrating the Spherical Fuzzy Sets (SFSs) and Alternative Queuing Method (AQM) to evaluate and prioritize ergonomic hazards. First, SFSs are employed to quantify the linguistic expressions of experts, addressing the inherent vagueness and uncertainty. Then, an entropy-based objective weighting method is adopted to determine the criteria weights. Finally, AQM is utilized to generate the risk priority. The proposed method has been implemented in a real-life construction project, where “overexertion due to unreasonable task organization”, “hypertension and heart diseases”, and “existing WMSD record” are identified as the top three ergonomic hazards. Then, a thorough discussion of intervention strategies regarding different risk categories is presented to facilitate ergonomic interventions. This proposed decision support system can promote effective ergonomic risk management, benefiting workers’ health and well-being and contributing to the sustainable workforce development of the construction industry.
