GMAA: A DSS Based on the Decision Analysis Methodology - Application Survey and Further Developments - Efficient Decision Support Systems: Practice and Challenges from Current to Future - page 277

Taking into account the above segments' rankings and the results of SA, the OEM
management finally recommended the best ranked segments, accounting for the 60% of the
total expenditure on non-metallic category segments, to be sourced from LCC, see Fig. 14.
3.4 Selection of intervention strategies against eutrophication and the drastic
decrease in the bird population in a fjord
DSS are also becoming increasingly popular in environmental management (Stam et al.,
1998; Tecle et al., 1998; Ito et al., 2001; Poch et al. 2004). Examples where MAUT has been
used for environmental management problems can be found, e.g., in the field of forest
management (Ananda & Herath, 2009), natural resource management (Mendoza & Martins,
2006)), different fields of water management (Linkov et al., 2006; Joubert et al., 2003), river
management (Reichert et al., 2007; Corsair et al., 2009), landscape ecology (Geneletti, 2005),
evaluation of farming systems (Prato & Herath, 2007), and site selection for hazardous waste
management (Merkhofer et al., 1997).
Many coastal zones all over the world have been put under increasing pressure from human
activities over recent decades, through overfishing, nutrient inputs, and global warming. A
related challenge is to come up with models that can accurately predict ecosystem changes
from human activity and preventive or remedial actions. In this sense, the GMAA was also
used to select intervention strategies against eutrophication and the drastic decrease in the
bird population in Ringkøbing Fjord (Bryhn et al., 2009; Jiménez et al., 2011).
Fig. 15. Ringkøbing Fjord
Ringkøbing Fjord is a large and shallow brackish lagoon on the west coast of Denmark. It
has an area of 300 km 2 , a volume of 0.57 km 3 , a maximum depth of 5.1 m and a mean depth
