ABSTRACT

As industrial systems expand and complex systems are developed, it is no longer effective to minimize hazards and risks for industrial safety using the technological solutions limited to a single industry. Thus, to resolve complicated problems, safety technology has been developed by promoting technology innovation and convergence. In this respect, this study aims at monitoring major safety fields and technologies through patent analysis to identify the trends in technology development that prevent the risks of various industrial systems. Patent information is effectively used for analyzing technology descriptions, which include the purpose and newness of technology. Using this patent information, we propose the major safety fields and related technology keywords using the following two techniques: (1) latent Dirichlet allocation (LDA), which aims to extract the latent topics and main keywords contained in documents, and (2) network analysis, which is useful for monitoring change patterns and relations. Further, the convergence trajectories of safety technology are identified to provide insights about the technology trends in safety fields. The results are expected to enable safety managers and engineers to effectively find relevant technology trends for reducing hazardous factors.

Conclusion

This study presents change and evolution of technology development for investigating various industrial safety issues. The safety technology has continuously been improved for protecting perilous and hazardous factors, covering all aspects of the safety fields, but previously, the studies of identifying major safety fields and technologies have rarely been conducted. Thus, the contribution of this study lies on monitoring major safety fields and improvement trajectories for providing the safety managers and engineers with practical insights. This is almost first approach to identifying the types of safety technology fields and the change of safety technology development. By visualizing convergence clusters and trajectories, we also monitor which technologies are mostly developed for safety. According to path of convergence trajectories, it is indicated that safety technologies are developed for safety in industrial sites, information systems, and vehicles. Each of safety technologies is directly or indirectly related to operations, worker, and system safety as well. The highlight of this study is that information technology is a dominant trend and plays a critical role in mediating between safety managers in the control tower and workers in the industrial site. Also, needs of product innovation in safety such as vehicles are addressed.
