"Open Systems Science: A New Research Methodology and its Application to Open Systems Problems"
In the 21 century, most of the important problems that we need to solve consist of integrated systems with many mutually-related, time-varying subsystems. These systems cannot be treated as closed systems but must be addressed as open systems. Problems of open systems cannot be solved simply by reductionism and therefore require a new methodology. Dr Tokoro proposes a new scientific methodology called Open Systems Science and shows some examples to which the methodology can be successfully applied including huge software systems, medical and environmental problems.

"Open Systems Dependability: A New Approach to Achieve Dependability of Huge and Complex Software Systems"
Today, most of the social infrastructure systems are supported by huge and complex software that must be dependable to provide sustainable services. However, such software systems inevitably involve incompleteness and uncertainty: incompleteness due to incomplete specifications and implementation which can be amplified by systems revision; and unpredictability due to requirements evolution, environmental changes, unexpected usage and attacks across networks. Therefore, it is almost impossible to treat such a system as a closed system whose functions and boundaries are fixed. Rather it must be approached as an open system whose dependability on huge and complex software systems is discussed and the notion of Open Systems Dependability is proposed. Then, the DEOS approach that integrates processes for development, operation and continuous revisions is described with the architecture which realizes the system.
