Intro -The roots of Boxed Economy- ? Agent Based Modeling Simulation Approach Boxed Economy! Boxed Economy Foundation Model Boxed Economy Simulation Platform

Overview image of Boxed Economy Foundation model modeling Boxed Economy is composed by the “Model” part and the “Platform” part. Model is in charge to declare the behavior of the model. Platform is in charge to Control or Manage the simulation. simulation BESP

BESP -Objectives of platform building- ? Difficulties of conducting a “Modeling to Simulation” Approach - Difficulty of Continuous&Consistent Research - Difficulty of Collaborative Research - Difficulty of Creating the tools for presentation Observing the target Comparing the behavior Between the Real and the Artificial Abstracting the feature Implementing the simulation Building the model Running the simulation Evaluating the simulation results Publication Boxed Economy Simulation Platform Achievements by using a platform ･ Enables Cumulative Research ･ Enables Collaborative Research ･ Ensures at least the minimum Quality ･ Enables to concentrate on Actual Modeling ･ Liberalization from creating the presentation

<Class Diagram of BEFM> BEFM -The Structure- <Class Diagram of BEFM> -BEFM is not an specific model used for a certain case of simulation. IT IS A FOUNDATION FOR ALL MODELS -An Agent in the BEFM is able to change its choice of behavior dynamically. -Each components can be implemented in parallel as long as they keep the rules -By using the Path, Agents exchange everything with other objects in the model. If they exchange words, it would be described as a communication

The coming Future -Our Schedule ahead- - Nov.2001 - Dec.2001 - Apr.2002 <Target > - Completion of BESP(ver0.8b) - Completion of Documentation (Japan) <Explanation> BESP would be updated; the technical design and the codes would be more sophisticated by this time compared to the present model. Support documents such as “user’s guide” and “technical materials” would be prepared by this time. But it would only be available in JAPANESE….(^^; <Target> - Complete Preparation of delivery (Middle of Dec.) <Explanation> - We would be ready to share BESP, BEFM and some sample models by this period. - Boxed Economy would be available via CD-Rom, WWW down loading. (We will be happy to send out the materials if you give us your addresses by cards or emails) <Target> - Completion of Documentation (English) <Explanation> - We would be hopefully be ready to send out the documents and all the support materials in ENGLISH. The following models would be delivered with BESP !!! Small Economy Model Small Market Model Format Competition Model

Thank you for your cooperation
