What are problems ahead? 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.

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.

component component platform platform

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.

Behavior Component

BESP Model Component Builder generates the java program code, just by making the state chart diagram and setting the model with a graphical user interface.

This part is generated by Model Component Builder This part is for you to write the custom code.

Once You Build the Components, Once You Build the Components,

you can use and set them without dealing with their source code !

Boxed Economy Foundation Model provides the design of the software architecture of social simulation for sharing and reusing the model components among the simulation builders, so that it will accelerate the P2P sharing of the models and components. It keeps the components

n track by defining the rule for designing

the components developed in the future.
