summary Design agents are rational agents that monitor and modify elements of a designed environment. Special characteristics of design agents include the ability to reason about patterns and concepts, and the ability to act autonomously in modifying or changing the design to achieve their own goals. 3D Virtual Worlds are multi-user distributed systems that provide a designed environment and a closed world environment for studying design agents in a multiagent system. We present a model for a design agent reasoning process and a model for constructing a memory of the agentís knowledge and interaction with a virtual world. The reasoning process includes sensation, perception, conception, hypothesizing, and planning a sequence of actions. Each agent has a constructed memory: a dynamic and changing view of the designed world that is determined by the agents sense data and reasoning. The agents construct and maintain a representation of the relevant objects in the world using a Function- Behavior-Structure formalism in order to reason about the intended and actual functions of the designed objects in the world. We have implemented this agent model by extending the Active Worlds platform so that each object in the 3D world can have agency. We illustrate the model with a door agent and a multi-agent room that reason about the use of the 3D world.
