Research-1Current Themes

Our final goal is the virtual manufacturing using novel computational methods especially considering uncertainty and/or variability for robust design, determination of a set of process parameters, risk analysis and quality assurance of products. Not only the numerical works but also experimental studies are carried out to obtain statistical data for probabilistic/stochastic simulation. Please also see the pages “JSPS KAKENHI project” and “For foreign students” for recently published journal papers.
