Applying Fuzzy Synthetic Evaluation Approach to Risk Assessment of Large-scale Activities
Zheng Jianhu,Huang Mingfang 보안공학연구지원센터 2016 International Journal of Security and Its Applicat Vol.10 No.8
Because of the complex and massive risk factors of a large-scale activity, it is difficult to assess the risk level for such activities with an accurate numerical value. Therefore, a fuzzy linguistic based approach was proposed to evaluate the risk level of large-scale activities. Taking Jay Chou’s concert in 2016 as a case study, a hierarchy structure for risk assessment index system was built from the interviews with experts and literatures, which contain 14 risk factors in 4 groups. A five-point scale linguistic term was designed for the experts to evaluate the risk level of risk factors, and a fuzzy synthetic assessment model was adopted to present the procedures of risk assessment. The results reveal that the top risk factor is “safety education” and the top risk group is “management”, and the overall risk criticality (RC) is considered as middle. Based on the rank of RC both for risk factors and risk groups, some risk management strategies were suggested.

The purpose of this study is to develop a new preventive risk management model for such activities as medical errors and accidents that occur in healthcare institutions. To conduct this study, the risk categories were classified by focusing on the medical and medical support departments through brainstorming with experts from the quality improvement (QI), nursing, and support departments of a comprehensive general hospital in Seoul during October 1-15, 2019. The results of the study indicate that the common factor of high risk items (RPN score) was the errors caused by poor management by the medical staff and support department providing the care service. This means that it can be fully preventable in advance of providing care services. It is also important to introduce advanced preventive systems to improve the care quality, in addition to reducing the risks that may result from lapse in good management practices. Thus, effective risk management in hospitals can be accomplished through preventive systems, staff training, and continuous monitoring of operations.
