3. Evaluating options
From COST Action FP0804: FORSYS
The tasks involved in this phase are
1. Selecting the best option
- In continuous case (see Malczewski 1999), the best option can be selected using optimizations tools, and in discrete case with multi-criteria analysis tools or voting methods.
2. Ranking alternative options
- If it is not enough to select one best option, the options can be ranked from best to worst. There may also be groups of options that are indifferent to the DM/stakeholders.
3. Aggregating preferences
- In case of several stakeholders / DMs the preferences need to be aggregated, in order to select the best option.
