This article provides an overview of the academic roadmap for modeling and simulation of social systems that was made by a working group of researchers from different domains. The roadmap was drawn along three axes that represent the future trend of technological development: scale/complexity, precision/reliability, and utility/applicability. The topics discussed cover a variety of domains and they are classified into two groups: one of them deals with general approaches of modeling and simulation of social systems, and the other deals with simulation techniques for more specific domains. What we should be concerned about in applying modeling and simulation to social systems were discussed also from a sociological viewpoint.
