Heretofore, the chief research staff (Hiroyuki Goto), collaborative researchers, and some of graduate students have been into the following themes:
1. Scheduling methods under limited resources
Keywords: max-plus algebra, optimal control, resource constraint, critical chain project management
2. Effective use of geographical information systems (GIS) data
Keywords: digital elevation, terrain analysis, data coding & encoding, parallel processing
3. Natural language processing (NIP)
Keywords: morphological analysis, indexing, classification & clustering, multivariate analysis
Our research policy is 'We go anywhere where there is a mathematical problem.' We do our best to assess, solve, and find a solution for various type of problems. Our challenge continues as long as there is a mathematical problem. We sometimes come across scientific but political issues wherein there is not a goal or rule. In such cases, we would ask 'What is your goal? (objective function), What are your rules or constraints?' Once they are clear, we may provide a new approach or solution method.
