most often used GIS-MADA method
- WLC model consists of two components:
- criterion weights:
- value functions: - The alternative characterized by the
highest value of V(Ai) is the most preferred
Confluence of the two research areas: one)

alternative in the q-th neighborhood

des AHP procedure involves three main steps:
- Normalization of Matrix C entries:
Analytic Hierarchy Process 1. Developing the AHP hierarchy
2. Assigning weights of importance to each element of the
hierarchical structure
- using the pairwise comparison method
- Then the weights are computes as follows:
Include
3. Constructing an overall priority rating
- One of the most comprehensive methods of
multicriteria decision analysis
s
- Based on three principles:
- Decomposition Hierarchical
- Requires that a decision problem be
decomposed into a hierarchy that captures Structure Analytic Hierarchy
the essential elements of the problem
Inclu Process
- Comparative judgment des

- Requires assessment of pairwise

comparisons of the elements within a given level
of the hierarchical structure, with respect to their
parent in the next-higher level - Global Method
- Synthesis of priorities
- Takes each of the derived ratio scale priorities
in the various levels of the
hierarchy and constructs a composite set of priorities
for the elements at the
lowest level of the hierarchy (that is, alternatives) Four levels:
- Goal
- Objectives
- Attributes
- Alternatives

specific target or goal Measures
- Ordering a set of decision alternative
on the basis of their separations from
some ideal/reference point
- Reference point: any significant target or goal
against which the decision alternatives are
evaluated Positive model:
- This hypothetical alternative is often defined in
terms of the positive ideal (utopia) point, or
negative ideal (or anti-ideal or nadir) point
- Positive and negative ideal points are determined
as the best and worst possible value achievable by
any alternative, respectively:
Spatially explicit
Negative model:
