چارچوب مبتنی بر استقرار عملکرد برای مدیریت ریسک فرایند حمل و نقل مواد خطرناک است

The risk management of hazardous materials (HazMats) transportation is a systematic process consisting of risk identification, evaluation, and control. A quality function deployment-based framework under fuzzy environment is proposed to effectively regulate the risks and manage the safety of HazMats transportation process. The framework includes three components. A 4D identification system, namely, “H (human) – M (material) – E (environment) – M (management),” for risk factors is constructed in the first stage, and the basic importance rating of each factor is calculated in the second stage. Subsequently, the corresponding risk control measures are proposed, and the correlation between risk factors and control measures are identified. Finally, the improved priority of each risk control measure, which is the benchmark for limited enterprise resource allocation and risk management policy development, is calculated in the third stage. In particular, this study utilizes fuzzy linguistic terms that are then transformed into triangular fuzzy numbers as evaluation tool for facilitating the expression of experts and decreasing information loss by considering the uncertainty and ambiguity of risk evaluation process. In addition, a new comprehensive weighting model is constructed to determine the influence of experts under group decision-making environment. The proposed framework is applied to explain the process of the risk management and loss prevention of a HazMats transportation company in China. Results not only provide certain acceptable recommendations to safety management of HazMat transportation process but also verify the feasibility and validity of the proposed approach.
