Recently, the agent-based simulation approaches have been remarkable to study social, economic, and financial complex systems. In these approaches, a designed agent often has many parameters which characterize itself, and these parameters are dynamically changed according to the ability of learning, evolution, and adaptation. Thus, it is necessary to confirm the methodologies to design, represent, and evaluate agents and interaction ovjectively. To overcome these issues, we found X-Economy Project in which we try to investigate the economic complex systems based on agent-based simulation approaches and propose the methodology for such research style. Namely, we have constructed the simulation platform, called X-Economy System, for artificial economy and artificial market. X-Economy System is expected to become the simulation system like Linux for such type researches. Especially, we have developed some research programs using X-Economy System for gradual investigation of complex economic systems. In this paper, the concept of X-Economy Project, the outline of X-Economy System, some research programs based on X-Economy System, and the aim of researches have been reported.
