What are problems ahead? We need the well-defined primitive terms and framework to describe the society by agent-based approach. It is necessary to support to implement the simulation for the simulation builder who has a little (or, no) skill of the computer programming. We need a system to share the parts of simulation models among two or more simulation builders. A Simulation Platform to help Building Block Approach

Boxed Economy Simulation Platform (BESP) Boxed Economy Simulation Platform (BESP) An integrated environment to make, execute, and analyze the agent-based social simulations. Implemented in Java language. The source code and detail specification are opened to the public. Architecture Overview of BESP Architecture Overview of BESP BESP is designed to realize an extensible software application with component-based architecture. The user can obtain the simulation model and environment which suit the needs, only if he/she sets necessary components into the platform. Model Components Presentation Components component component platform BESP platform Boxed Economy Simulation Platform
Plug- -in Presentation Components in Presentation Components Plug A presentation component is a software component Presentation Components for the user interface to operate and to visualize the simulation, and the output into the file. BESP Boxed Economy Simulation Platform (1) Drop the presentation component (.class or .jar) into a “plugin” folder (2) Restart BESP Plug- -in Model Components in Model Components Plug The model component is a software component that Model Components implements the model which the user wants to simulate. BESP Boxed Economy Simulation Platform BESP Model Composer (1) Drop the model component (.class or .jar) into a “plugin” folder (2) Select and set the property with BESP Model Composer.
