Advanced Researches on Intelligent Spatial Decision Support System (ISDSS): A Combination of Model-Blade, Generalized Repository and GIS

In the traditional Spatial Decision Support System (SDSS), most of the GIS systems only take the database system as the driving core, provide the raw data and the information from limited spatial processing. It can not give substantive solutions to satisfy the weak-structure system in most decision support applications. Moreover, models in SDSS often get the wrong analytical results because of lacking the corresponding spatial parameters et al., and the analytical results are poor visualization for the users. In this paper, we presented the concept of Model-blade base based on object-oriented and the realization principle, combining with the enhanced generalized repository and GIS database researches indicated that taking model-blade as the core, generalized knowledge as the drive, the new Intelligent Spatial Decision Support System(ISDSS) can integrate the model-blade base, the generalized repository and the GIS database technology into GIS, realize the seamless integration of them.finally,we using the Hazardous Chemical Leak(HCL) model-blade and the generalized knowledge(such as historical cases of hazardous chemical leak, expert knowledge & experiences corresponding to hazardous chemical leak and data mined from GIS database) as an example to demonstrate the feasibilities and advances of ISDSS.
