复杂系统是独立的代理人相互作用，并与他们的环境产生紧急行为的集合。基于Agent的计算机仿真是研究复杂系统的主要方法之一。由于通信开销大，并且由于共享计算平台的交互代理之间的死锁范围，这种模拟的幼稚方法可能效果不佳。代理交互可以完全从代理交互的环境的角度来考虑。使用这样的环境定向来构造模拟导致减少通信开销的模拟，其有效地无死锁，并且仍然以所需的方式表现。此外，面向环境的体系结构简化了更复杂的大规模模拟的开发，具有多种复杂的代理，位于多种环境中并与多种环境交互。我们描述了面向环境的仿真体系结构。我们报告了一些实验，证明了环境导向的方法的有效性：一个简单的植绒系统，植绒系统与多个感官环境，和植绒系统在外部环境。
Complex systems are collections of independent agents interacting with each other and with their environment to produce emergent behaviour. Agent-based computer simulation is one of the main ways of studying complex systems. A naïve approach to such simulation can fare poorly, due to large communication overhead, and due to the scope for deadlock between the interacting agents sharing a computational platform. Agent interaction can instead be considered entirely from the point of view of the environment(s) within which the agents interact. Structuring a simulation using such Environment Orientation leads to a simulation that reduces communication overhead, that is effectively deadlock-free, and yet still behaves in the manner required. Additionally the Environment Orientation architecture eases the development of more sophisticated large-scale simulations, with multiple kinds of complex agents, situated in and interacting with multiple kinds of environments. We describe the Environment Orientation simulation architecture. We report on a number of experiments that demonstrate the effectiveness of the Environment Orientation approach: a simple flocking system, a flocking system with multiple sensory environments, and a flocking system in an external environment.
