Dr. Dohi is serving as an Editorial Board Member of Asia-Pacific Journal of Operational Research,Journal of Risk and Reliability, Journal of Autonomic and Trusted Computing, International Journal of Reliability and Quality Performance, International Journal of Quality, Statistics, and Reliability, International Journal on Computer Science and Technology, etc. Dr. Dohi served as a Guest Editor of journal special issues in ACM Journal of Emerging Technologies in Computing, Communications in Statistics, Telecommunication Systems Journal, among others, and a General Chair of several international conferences such as AIWARM 2004--2008, APARM 2010--2012, WoSAR 2008-2010, MENS 2010, IEEE ISSRE 2011, IEEE UIC-ATC 2012, and as a Program Committee Member of several premium events such as IEEE ISSRE, IFIP/IEEE DSN, IEEE COMPSAC, IEEE SERE, IEEE PRDC.
Toshio Nakagawa already published more than 200 papers mainly on the subject of reliability theory in research journals, and has already published under the titles of "Maintenance Theory of Reliability" in 2005, "Shock and Damage Models in Reliability" in 2007, "Advanced Reliability Models and Optimum Policies" in 2008, and "Stochastic Processes with Applications to Reliability Theory" in 2012 from Springer. His research group in Nagoya, Japan, has continuously studied reliability theory and their applications since 1988, and has presented a large number of papers in reliability journals and at international conferences. Most papers have been written using some techniques and results of reliability and maintenance theory.
