Laboratory for System Dependability

Envision safer and secure society through dependable ICT systems.

==Notice==
The laboratory was just launched on February, 2019.
We are open to any collaborators and students who are willing to contribute the society through designing dependable systems, who would like to study the applications of stochastic models, and/or who are interested in dependable machine learning systems and IoT systems. Please contact us!

Overview

Our society is increasingly relying on ICT systems supporting smart transportation systems, power grid, financial, medical systems and so forth.
Since those ICT systems are indispensable for our lives, continuous engineering efforts to improve system dependability are imperatively important.
Our research laboratory tackles this issue by leveraging stochastic models and analysis techniques.
We model various uncertainties causing system misbehaviors such as component failures, estimate the system dependability quantitatively,
and evaluate the effectiveness of the measures to improve the dependability with lower cost.
