Arima Lab
Machine-translated · View original
A lab that explores production systems through data analysis and mathematical optimization.

AboutAbout the lab
Studying production systems with data and optimization.
The Arima Lab studies production systems engineering, production quality management, and operations management based on the analysis of IoT and big data.
Its research centers on practical applications of data analysis and mathematical optimization, and is applied across a wide range of areas, including manufacturing and services.
The lab puts particular effort into the Social Engineering Workshop, in which mixed teams of undergraduate and graduate students work to solve real-world problems from companies. Some students continue the work as research.
In the introductory lab seminar, students are assigned roles and give presentations. From June onward, they deepen their understanding by taking turns presenting books and prior studies related to their research themes.
