expressions of some set of genes for a specified set of patients. This visualization also
interoperates with the patient selection by the parallel coordinate system. Such an ad hoc
introduction of new components with their interoperation with existing components can
be implemented just by defining a new parent-child relationship with an appropriate slot
connection.

Application to Social Cyber-Physical Systems for Optimizing
Social System Services
Around 2010, the present author was asked by MEXT (Ministry of Education,
Culture, Sport, Science and Technology) of Japan to make a new R&D Plan for the
next generation IT infrastructure technologies for optimizing social system services.
This turned out to be a one year feasibility study project in 2011, and then in 2012 a
five year government initiative project on social cyber-physical system technologies
for optimizing social system services. This is a joint project with NII (National
Institute of Informatics), Osaka University, and Kyushu University. Our team picked
up the snow plowing and removing in Sapporo as a complex social system service.
Sapporo has 1.9 million people and annual snow fall of 6 meters, and spends more
than 15 billion yen every year just for snow plowing and removing.
Our preparatory study showed that macro analyses of probe car data for the whole
city area would not give any meaningful knowledge about the influence of snow fall,
snow plowing and removing on traffics [21]. Clustering analyses of road segments
with respect to their traffic changes in a day told us that even those segments along
