“…T He construction industry has been highly active in recent years, and the number of construction projects is considerable owing to the development of new and repair of existing infrastructure. However, because of the significantly declining birthrates coupled with an aging population since the 1990s, the working-age population has been declining [1], [2]. In particular, the turnover of generations with skilled workers is considerable, and has contributed to the decrease in productivity at construction sites.…”

In recent years, the working population in the construction industry has been declining. However, the number of construction works projects is increasing because of the increase in development and infrastructure maintenance. Therefore, it is necessary to meet this increasing demand with limited resources. Productivity at construction sites is significantly improved through the extensive use of hydraulic excavators. However, productivity is affected by the skill of excavator operator. In addition, it is difficult and time-consuming to learn the operation of the machines required to achieve an efficient level of work. Therefore, novice operators need support to achieve high productivity. In this study, the behavior of the combined center-of-mass of the excavator attachment as an index that expresses the difference in operating characteristics of operators for hydraulic excavators is focused. In addition, a control system that assists the operation in excavation work based on the velocity of the combined center-of-mass of the attachment is proposed. Furthermore, the database-driven control is applied to correspond to the nonlinear characteristics of a hydraulic excavator. The proposed method is implemented on a hydraulic excavator and its effectiveness is verified.

“…In response to such issues, the Ministry of Land, Infrastructure, Transport, and Tourism is promoting 'i-construction'. This program highlights the active utilization of information and communication technology for construction machines and the automation of operation to reduce the number of workers and attempt to improve productivity at construction sites with limited resources [3][4][5][6]. Furthermore, as processing becomes more sophisticated and faster, it is important to make good use of a large amount of information such as urban, traffic, and meteorological data [7].…”

In industries, particularly the construction field, the number of workers is decreasing because of the falling number of young new hires and the increasing number of existing elderly workers. Therefore, it is important to improve the productivity of each worker at a construction site. At many construction sites, operation and decision-making skills of construction machine operators are required, and work productivity depends on these skills of the operators. However, the number of elderly skilled operators is decreasing, and it is necessary to accurately train young unskilled operators to develop the aforementioned skills in order to improve productivity. Thus, a system that can quantitatively evaluate the operation skills of the operator is required. This study proposes a system that can quantitatively evaluate the operator's skills by using a database-driven technique. The proposed method is applied to the swing operation of a hydraulic excavator. Furthermore, skill evaluation is carried out by multiple operators, and the effectiveness of the proposed method is verified.
