Applying Constructionist Design Methodology to Agent-Based Simulation Systems

摘要

Among the benefits of agent-based modeling is parallel development and implementation of components. Integrating large numbers of agents developed by many is, however, a significant challenge. Further, architectural changes can require significant redesign. We have developed CDM-S, the Constructionist Design Methodology for Simulation, an agent-oriented methodology for developing, implementing and evolving multi-agent systems. CDM-S's strength lies in simplifying modeling and construction of systems with architectural evolution of complex control hierarchies and data flow. We have applied CDM-S in the development of a family of market simulations where companies, employees, banks and consumers are modeled at multiple abstraction levels. These were designed and built by 14 students over a period of 10 weeks. Experience shows CDM-S to be a promising high-level methodology for constructing large multi-agent systems. Here we describe CDM-S and present data on its application in the development process.
