Occupational safety issues encountered in the worksite environment are the issues that companies should consider in improving their operations with a view to human health and environmental awareness. Many methods with different rationales have been existed in the literature to prioritize hazards according to their risk levels and to mitigate their consequences. In this study, a new model is developed for occupational risk assessment by merging two well-known multi-criteria decision-making methods named best and worst method (BWM) and multi attribute ideal real comparative analysis (MAIRCA) under fuzzy environment. The proposed model differentiates from other similar models by three aspects. First, it considers severity of a hazard and its associated risk from the human and environmental riskiness perspectives. Secondly, it applies fuzzy BWM (F-BWM) to calculate the relative importance of three risk factors named as “probability, frequency and severity” of traditional Fine–Kinney method. Thirdly, it applies fuzzy MAIRCA (F-MAIRCA) to rank hazards according to their risk level using importance values obtained by F-BWM. To show applicability of the approach, a case study of risk assessment in a marble factory is fulfilled. Additionally, a number of validation studies including benchmarking analysis with fuzzy VIKOR and fuzzy TOPSIS methods; a sensitivity analysis by varying importance weights of risk factors are carried out to highlight the solidity of the proposed approach.

从人类健康和环境角度评估职业风险:一种新的综合方法及其在模糊BWM和模糊MAIRCA中的应用

在工作场所环境中遇到的职业安全问题是公司在改善运营以考虑人类健康和环保意识时应考虑的问题。文献中已经存在许多具有不同原理的方法,以根据危险的风险等级对危险进行优先级排序并减轻其后果。在这项研究中,通过合并两种著名的多准则决策方法(最佳和最差方法(BWM)和多属性理想真实比较分析(MAIRCA)),开发了一种用于职业风险评估的新模型。所提出的模型在三个方面与其他类似模型有所区别。首先,它从人与环境风险的角度考虑了危害的严重性及其相关风险。其次,它应用模糊BWM(F-BWM)来计算传统Fine-Kinney方法的三个风险因子(概率,频率和严重性)的相对重要性。第三,运用模糊MAIRCA(F-MAIRCA),使用F-BWM获得的重要性值,根据危险等级对危险进行排序。为了显示该方法的适用性,完成了大理石工厂风险评估的案例研究。此外,还有许多验证研究,包括使用模糊VIKOR和模糊TOPSIS方法进行的基准分析;通过改变风险因素的重要性权重进行敏感性分析,以突出所提出方法的可靠性。它使用模糊MAIRCA(F-MAIRCA)使用F-BWM获得的重要性值根据危险等级对危险进行排名。为了显示该方法的适用性,完成了大理石工厂风险评估的案例研究。此外,许多验证研究包括使用模糊VIKOR和模糊TOPSIS方法进行的基准分析;通过改变风险因素的重要性权重进行敏感性分析,以突出所提出方法的可靠性。它使用模糊MAIRCA(F-MAIRCA)使用F-BWM获得的重要性值根据危险等级对危险进行排名。为了显示该方法的适用性,完成了大理石工厂风险评估的案例研究。此外,还有许多验证研究,包括使用模糊VIKOR和模糊TOPSIS方法进行的基准分析;通过改变风险因素的重要性权重进行敏感性分析,以突出所提出方法的可靠性。
