Applying fuzzy grey quality function deployment to identify solutions for improving safety of container terminal loading and unloading operations

Abstract

The safety of container terminal loading and unloading operations is an important link in international port logistics, and such operations deeply affect terminal operating efficiency and service quality. Finding solutions for improving the safety and quality of loading and unloading operations has therefore become very important. In this article, a fuzzy grey quality function deployment approach was developed to identify solutions for improving the safety of container terminal loading and unloading operations in Taiwan. First, the fuzzy grey quality function deployment approach was presented. Second, this study employed a house of quality to facilitate investigation of the 18 safety needs' attributes and 10 feasible technical solutions. Safety needs, and their importance and satisfaction, were then examined via an expert questionnaire. Subsequently, a fuzzy relationship matrix was constructed to link technical solutions and safety needs in a fuzzy decision environment. Finally, the fuzzy grey quality function deployment approach was applied to prioritize technical solutions regarding improving the safety quality of container terminal loading and unloading operations in Taiwan. This study's results show that the top six most feasible technical solutions for improving the safety quality of loading and unloading operations are implementing professional education and training,enhancing safety awareness and behavior of personnel,developing effective standard operating procedures,adequate safety equipment,establishing a good safety climate, and regular maintenance of hardware and equipment. These top six technical solutions are also discussed in this article.
