Fuzzy risk assessment on safety operations for exclusive container terminals at Kaohsiung port in Taiwan

Abstract

Because risk assessment of safety operations in exclusive container terminals at Kaohsiung port involves a host of complex considerations and uncertain information, we therefore use a fuzziness-based method to minimize the effect of such adverse factors and clarify the assessment process in this article. This article therefore uses fuzzy risk assessment steps to evaluate safety operations in exclusive container terminals at Kaohsiung port in Taiwan. This article first employs three risk assessment steps and then identifies a total of four dimensions with 16 risk factors from the literature and interviews with experts. After proposing a systematic fuzzy risk analysis and evaluation steps in order to determine risk levels, this article conducts an empirical study of Kaohsiung port by means of a survey. The empirical results reveal that (1) the leading factor influencing risk frequency is ''communication misunderstanding,'' (2) the leading factor influencing risk severity is ''human negligence and error,'' and (3) three risk factors are located in the high-risk area, while the other 13 risk factors are in the medium-risk area, and no risk factors are in the low-risk area. Furthermore, the analysis of the various risk factors suggests the adoption of three risk management strategies.

Selection of effective risk mitigation strategies in container shipping operations

“…A fuzzy AHP analysis includes the following eight main phases (Buckley, 1985;Ding, 2010;Ding and Tseng, 2012):…”

Applying Fuzzy Synthetic Evaluation Approach to Risk Assessment of Large-scale Activities

“…The results indicate that the top two risk groups are associated with human, which in accord with the results of most literatures. In other words, accidents are most likely caused by human related factors [13,21]. The lowest risk group is "infrastructure", because of Fuzhou Strait Olympic sports center stadium is a new stadium with high designed standard.…”

“…In these circumstances, the measurement of a risk criterion is suitable expressed by means of fuzzy linguistic term. According to literatures, measurement of risk probability and risk severity usually adopted five-point or seven-point scale [13,16,17]. In this work, a five-point scale linguistic term is adopted for evaluation the RP and RS: 1= very low, 2 = low, 3= middle, 4 = high and 5= very high.…”

“…The fuzzy set theory is considered as suitable tool for risk assessment, because it can deal with the problems relating to subjective and imprecise evaluation. In addition, the fuzzy set also allows mathematical operation with linguistic terms for decision-making [12][13]. Fuzzy synthetic assessment model is proposed for a synthetic evaluation in an uncertain environment with multiple criteria, and it is widely adopted in the field of risk assessment.…”

Use of a Hybrid McDm Method to Evaluate Key Solutions Influencing Service Quality at a Port Logistics Center in Taiwan

“…During the 1990s, Taiwan's Kaohsiung port made active efforts to boost added service value in the maritime transport market [3,4], and also use more effective operating methods to ship international cargo to all parts of the globe. As a result, by providing efficient logistics services platforms [5] and an effective marine terminal [6], Kaohsiung port was one of the most important maritime transport logistics centers in the Asia-Pacific region for a period of time [1,2,7], and was the world's third largest container port in 1999. However, Taiwan currently faces severe competition from the cargo logistics markets of China, Northeast Asia, and Southeast Asia, and the surging cargo volume and geographical locations of ports in these regions are making them an ever-greater threat to Taiwan's ports.…”
