Résumé:
The reduction of socio-spatial disparities between the districts of the city of Boussaâda, can
takes at least two paths, one towards the relocation of people to weave a social mix, the other relies on the
strengthening of services and equipment in order to to make precarious outlying neighborhoods more
competitive and attractive. The quantitative analysis of the socio-spatial disparities between the districts of
the city of Boussaâda, confirms the ghettoization of the peripheral districts, with (6) as index on the
typology of Poulsen, (0,780) as index of uni-group Segregation. The weighted combination of these
results with the spatial factors defined by the success rates for the BAC and BEF exams and the travel
time to the city center and neighborhoods results in an overall zonal suitability index (IAZG), With (0.41 )
rating given to the Quartier Maitar summarizes the infinitely low level of service available to the
populations of the district. These results are the conclusion of a combination of several methods, MCDA
(AHP) and Zonal Fitness (IAZG). The contribution of this thesis is the construction of an IAZG,
composed of several factors of socio-spatial disparity between the districts of the city of Boussaâda, used
as an index of inter-district disparities it will be the basis of the decision to allocate the facilities across the
city's neighborhoods. It is the result of a weighted combination between the factors of the multi-criteria
decision taken by several actors in a transparent environment and which respects the principles of equity
and sustainable development. The Hierarchical Analysis Procedure (AHP) (Saaty T., 1990) is used for
weighting decision factors in the Multi-Criteria Decision Aid (MCDA) method. The result of this
procedure is the ranking of the proposed alternatives, with the aim of reducing disparities between
districts. Without ambiguity the final decision is taken by the politicians and in the presence of all the
actors who participated in the decision
