ABSTRACT

Optimized site selections for urban facilities and services could be mentioned as one of
the most important factor in urban management. In this context, several factors
influence on decision making for site selection that by considering each of them,
management could optimize the usage of equipments by employing the standard
criteria.

In this study, with regard to different criteria in selecting appropriate waste storage
locations, which reaches both economic-technical and environmental considerations,
and by employing Fuzzy Logic, Analytic Hierarchy Process (AHP) and Geographic
Information Systems (GIS) coupling model, the site selection has been carried out for
Si-Sakht Town in Dena City. Due to flexibility of fuzzy mathematics for modeling the
real world, fuzzy logic is more suitable method for decision making compared to
classical methods. In this way, first of all the important and influential factors in
selecting the appropriate locations, such as land slope, bed-rock and geology, distance
from surface water resources such as rivers and streams and sub-surface water sources
such as wells, distance from the underground water table, agricultural fields and gardens
and also distance from city have been extracted and classified. Then, by employing
Analytic Hierarchy Process (AHP), all of mentioned base layers have been weighted.
Converting all of base layers into weighted maps is the next step of presented study
which has been done in a GIS Framework. By overlaying the mentioned weighted maps
in order to the grant of them, Site selection has been carried out. Eventually, the
appropriate waste storage locations, which satisfying environmental, economical and
technical considerations, have been extracted.

Keywords: Site Selection, Waste Storage, Analytic Hierarchy Process, Fuzzy Logic, GIS.
