Abstract: A system and method of modelling interaction between a plurality of agents and an environment, comprising providing agents with simple characteristics and storing those characteristis, storing detailed information on the complete environment and allowing the agents to access environment information from the stored detailed information on a location by location basis and use the information to progress through the environment, such that a processor can monitor these movements to determine suitability of the environment by providing an underlying environment map which is highly detailed and which is accessible by the simple agents. A more efficient and user friendly system and method for evaluating environment layouts is provided.
