Spatial Decision Support System Platform and Its Applications
空间决策支持系统开发平台及其应用实例

Spatial Decision Support System (SDSS) is a new field developed on the basis of Geographic Information System (GIS) and Decision Support System (DSS). Since the late 1980's, more and more attention has been paid to the technology of SDSS in China as well as in the world. Through analyzing a large number of literature on the study of SDSS, it can be seen that presently people have many different understandings of SDSS. From authors' point of view, only those systems which can provide decision makers spatial decision making schemes are deemed as SDSS and divided into three levels: general platform, domain tools and application systems. This paper will discuss the basic concepts and classification system of SDSS, architecture and operational modes of SDSS Platform (SDSSP), and generation process of a SDSS application system, such as Spatial Decision support System for Agricultural Investment Planning in China (SDSS/AIPC), supported by SDSSP.
