Insights into modern reliability engineering

“My research is based on reliability engineering,” says Lu Jin, an associate professor at the Department of Informatics, UEC Tokyo. “I am working on maintenance planning to study a wide range of systems for ensuring the safety and security of our society. The interest of my research is developing decision-making models for realizing more flexible and efficient maintenance plan while maintaining high reliability and safety.”

Jin is developing decision-making models for systems focused on optimizing problems for maintenance plans such as periodic maintenance and condition monitoring maintenance.

Specifically, Jin wants to reduce maintenance costs while maintaining reliability levels by dynamically adjusting and controlling maintenance plans based on monitoring information on operating systems. A maintenance plan that uses the Markov decision process as the core model, takes into consideration the effects of direct and indirect measurement of system deterioration, measurement accuracy, changes in the operating environment, and so on, and yields a trade-off between maintenance costs and failure losses.

Recent research results on maintenance decisions that take into account the uncertainty and changes in information being monitored.

“I'm also working on joint research with colleagues at Mälardalens University in Sweden, on using existing maintenance optimization methods in other fields such as pricing options and examining investment strategies. This is an exciting area of research.”

The important point is that this system includes entertaining games that children enjoy playing and thereby wear the spectacles continuously for periods of times that are much longer than eye-patches.

“We worked with globally renowned game making companies to design enjoyable games for children,” says Ishigaki. “Our system has a wide range of games and special glasses catering for children of all ages.”
