SPADES 被设计为通过多个机构来运行一个模拟。其中一个就是协调和通讯的中心，它将把模拟引擎和世界模型作为一个单独的过程运行。模拟世界的设计者必须得链接到模拟引擎库创造一个实体，这个实体必须最先运行。
SPADES was designed for the adoption of a number of institutions to run a simulation. One is the coordination and communication center, which will combine the simulation model engine and the world as a separate process running. Simulation of the world's designers must have link to the simulation engine to create an entity, the entity must first run. (2007-05-22, PPT, 25KB, 下载2次)
