Space In The Gdss Decision Support Technology

Spatial Decision Supporting Technique comes into being when Decision Supporting Technique and Geographic Information Technique are combined. Having its own prominent characteristics, Spatial Decision Supporting Technique can deal with many decision problems of semi-structurization and even non- structurization and treat with problems systemically and intelligentizedly and offer rewarding decision through automatic judgment, analysis, and induction of spatial massage, spatial relationship and spatial distribution law, making use of mature model and knowledge bases.It can also overcome the present drawback that Interactive is much depended on and thus the handling capacity of computer can not be brought into full play. It can also get the intelligentized processing and decision making of Large Data to become true. Originated from Geographic Information Technique, Spatial Decision Supporting Technique can offer corresponding spatial knowledge and decision supporting for information management, process control and scientific research, etc.This thesis addresses itself to the basic conception and development of the current Spatial Decision Supporting Technique, analyzing the characteristics of spatial data and spatial entity and spatial decision supporting and discussing the realizing methods of spatial decision supporting. The discussion of some techniques that can be applied to spatial decision analysis follows and then the main development tool is chosen by comparison. Next data management of spatial decision supporting system is explored emphatically and spatial database is introduced to administrate spatial data. In order to carry through spatial decision, spatial analysis is further introduced.In the end, some basic decisions in spatial decision supporting, such as best route decision and best troop distribute decision, are realized in accordance with specific developing contents, taking into consideration the research result discussed above.In the final part of this thesis, I make a further summary concerning my work and put forward some of my own opinions for the future researches in this field, according to my research experience of Spatial Decision Supporting.
