摘要
将G IS技术与专家系统相结合,先对城市地理空间数据进行表示,然后用与或树结构对公共交通领域知识进行表达,并采用深度优先搜索和回溯技术实现推理引擎。对GIS和ES之间的接口和其中所涉及到的空间知识进行了研究探讨。所构建的辅助决策系统能够很好地对城市公交线路进行指标评测和完成对公交专用道规划的选取。
This paper proposed a novel decision-making system by combining GIS with ES. The proposed system first ex- pressed the city public traffic geographical data in GIS, and adopted the and/or tree to represent the knowledge of the public traffic, on which the deduction engine could be realized by u.sing the depth-first searching and the backtrack strategies. It discussed the interface between the GIS and ES and the spatial knowledge. Experiment results present that the decision-maklng system can evaluate well the public traffic routes and accomplish the setup of bus lanes.
