Quarrying industry is a significant business sector; it presents a job opportunity also, a significant source of income through taxes that contributes to local economic development; but it generates negative effects on the environment. The awareness of the protection of the environment requires the reconciliation between the imperatives of preserving the environment and those of sustainable socio-economic development. In this context, this paper presents a study of this activity taking into consideration several heterogeneous variables measured on the study area (province of Settat, Morocco). Which is located in the center of Morocco on the phosphate plateau which is characterized by a geological diversity conducive to the quarrying activity with these 111 quarries which are exploited there it presents a very adequate frame to the study. This is followed by a post-observational analysis of multivariate statistical analysis, the purpose of which is to reduce a large set of variables to a small set that still contains most of the information in the large set.

The growth of logistics sector has become a priority in public policy as well as determinant factor in territorial structuring strategies. And in the global competitive environment, major economic interests are increasingly expanding while other territories have difficulty to attract the indispensable economic infrastructure for their development..
The objective of policy makers being able to attract investment, generate added value, sparking the interest of any form of settlements to contribute to the economic development of the territory.
The main purpose of this paper is to propose a multi-criteria methodology in order to judge the appropriateness of industrial facilities location demonstrating the decisive character of logistics in the industrial positioning of a territory.

The main purpose of the current study is to develop a tool for supporting decision-making based on geographic information systems integrated multi-criteria decision support system use for industrial location. The method used here is based on environmental, social and economic criteria of the industrial location. The selection of these criteria is based on the study of several models of sustainable development indicators. Then the aggregation of these criteria by the Measuring Attractiveness by Categorical Based Evaluation Technique tool allows us to evaluate the importance, to give each criterion a weight that many decision makers (public decision makers, industry professionals, public agency...) had previously consented. Finally the integration of multi-criteria model with a geographic information system enables e assessment of the spatial analysis on the whole territory for the selection of industrial sites.
The current study had been carried out on the region of Chaouia-Ouardigha Morocco and allows a synergetic evaluation of the suitability of the location of 12 existing industrial sites and provides also the opportunity to make the optimal choice of future industrial sites location.
