Tools and Techniques for Use in Decision Support Systems Managers at all levels find decision support systems (DSSs) difficult to Multiple criteria decision -making techniques and their applications – a review of the literature from to An Examination of Relationships during DSS Application Development . user views a model as a virtual relation repre- senting a may even be unaware that the DSS uses models in There are at least two approaches to building. Decision Support System and Customer Relationship Management We will show that used independently these tools offer reduced services, but when Viability, evolution and autonomy requested by users for their information system are.
There was a problem providing the content you requested
However, in order to be able to provide the information that each expert would find relevant, the user must be involved in the development and the post audit evaluation of the decision support system Liebowitz This involvement must span not just the content issues, but also the presentation and the organization of the information. This is necessary to ensure that the system fulfills the three criteria that determine its success, namely compatibility, understandability, and effectiveness Rouse in Liebowitz If these three criteria are met, decision support systems can be invaluable in expanding the scope of information that each expert can handle.
As a result, cognitive limitations become less important in determining the amount of source material that the expert can use. One advantage and limitation of the decision support system is that it is user driven. This implies that the system answers queries what the expert inputs, but does not carry out further analysis on its own.
Knowledge Management Tools
It is therefore not a form of artificial intelligence like other decision-making tools. Knowledge management KM is involved in two ways here. Normally the area that is emphasized is that decision support systems can enhance the manager's knowledge through knowledge discovery and supply of relevant information.
- Decision support tools
The integration of different type of knowledge e. Criteria, objectives and constraints about the problem become more explicit through the whole process of development and application of a decision support system.
The graphical features of a DSS support communication between stakeholders with different backgrounds.
Decision Support Systems
Visual aids in DSS also become more and more important when audiences are composed not only by policy makers but also by citizens. Communication capabilities help in fostering public participation are particularly developed in Deliberation Support Tools. For instance multi-criteria decision making for the evaluationbenchmarking and raking of the different options identified. Optimisations models integrated in the systems help to identify the best between the generated alternatives.
The use of GIS in Spatial Decision Support Systems allows for the definition hydrological and socio-economic maps that help in the multi-criteria analysis of the problem at hand.
GIS components helps in the visualisation of the location of measures and impacts and facilitate the problem assessment by providing important information for the allocation of water management infrastructures. A DSS help in documenting the decision process that leads to the choice of a particular option thus contributes to its increasing transparency and fairness.
