2. Decision Evaluation in Complex Risk Network Systems
DECERNS –
Decision Evaluation in Complex Risk Network Systems
The main objective: creation of methods and software tools that will provide decision support on land use planning and management.

3. Integration of: GeoInformation systems (GIS),
Multi-Criteria Decision Analysis (MCDA),
Models – human health risk, ecological risk, economical assessments

4. Implementation
analysis of spatial multi-criteria problems site-suitability problems, housing development, site-selection, habitat site selection, location of a facility, etc.
land use planning and management allocation of land to different uses: agriculture, recreational, including waste disposal, health care resource allocation, etc.

5. Generalized architecture
Web Application
Stand-Alone
Application
WEB Services
Program Libraries
GUI (Swing, HTML & JavaScript)
Application Programming Interface (API)
GIS subsystem
- Vector and Raster models
- Basic / Advanced GIS functions
- Geostatistical analysis
DSS subsystem
- Basic / Advanced MCDA methods
- Group and Individual methods
Models
Standard or Application
Specific models
Application specific data

6. GIS subsystem main functions:
Multi-layered maps visualization and coloring
Measurements (distance along polylines, polygon area)
Zooming and Panning
Features selection (single and multi select) and searching
Overlays
Buffering
Rasterization
Spatial interpolation and geostatistics
Support of all common map formats

7. GIS: multi-layered map visualization

8. GIS: buffer zones

9. GIS: overlays 3 2
Intersection 4 1
Join,
Subtraction

10. and other functions ...

11. MCDA subsystem provides implementation of
Different MCDA methods (MADM)
MAVT, AHP, TOPSIS, PROMETHEE; and advanced methods: MAUT, ProMAA, Fuzzy MAVT, FMAA
Effective interaction with GIS subsystem
Individual and Group Decision-Making Support

12. MCDA: Value Tree

13. MCDA: performance table

14. MCDA: base methods MAVT – aggregation AHP – pairwise comparison
TOPSIS – distance to ideal point
PROMETHEE – pairwise comparison based on preference functions

15. MCDA: advanced methods
MAUT – (uncertain criterion values/= probabilities)
Fuzzy MAVT (MAVT + uncertainty/ = fuzzy theory
ProMAA – Probabilistic Multicriteria Acceptability Analysis, distrinuted criterion values and weights probability that alternative will have rank k
FMAA – (MAA + fuzzy criterion values and weights)
