摘要
针对选址决策特点,提出了基于知识的选址决策支持系统模型、结构,重点分析了系统知识获取、知识库设计和分层次推理策略;在知识获取中,引入知识挖掘手段,实现系统部分知识的自动获取。从决策目标和规则生成、适宜性推理、决策推理等方面,探索智能化选址空间决策支持系统的构建方法,实现了与GIS、应用分析模型的紧密耦合集成,并用实例分析说明了系统的信息处理流程和可行性。
A knowledge-based decision support system model for site-selection completely according to the process and character of site-selection is provided, the knowledge representation and acquisition, and reasoning strategy are discussed, decision-tree to partly realize automatically knowledge acquisition is introduced. The frame and design of spatial decision support system for site selecting roundly is discussed, including decision target creating, suitability reasoning and decision reasoning. An Ecological Park＇ SDSS for site selecting is implemented with the deep-coupled integrating mode. A case study of site-selection analysis for an environmental-friendly agricultural project demonstrates the approach.
