Introduction to DecernsSDSS
DecernsSDSS1)2) is a web-based spatial decision support system (WebSDSS) for multi-criteria analysis of a wide range of [spatially-distributed] alternatives. DecernsSDSS integrates basic and advanced GIS3) functions with several MCDA4) methods and tools. MCDA and GIS subsystems/modules of DecernsSDSS may be used independently. One of the features of the DecernsSDSS is a capability to incorporate various generic/site-specific models for risk analysis and assessment of other decision criteria which are considered within a [spatial] multi-criteria problem.

The following acronyms are used in this User Manual:
1) Decerns/DECERNS = Decision Evaluation in Complex Risk Network System
2) SDSS = Spatial Decision Support System
3) GIS = Geographic Information System
4) MCDA = Multi-Criteria Decision Analysis
