Integration approach of multicriteria analysis to OLAP systems: Multidimensional model

The decisions support Systems are based on decision technologies enabling organizations to make better use of their data flow analysis by simplifying them. Indeed, OLAP (On Line Analytical Processing) tools such as decisional technology, offer the possibility of archiving, management, analysis and multidimensional modeling. However, they are limited in the consideration of the multicriteria and quality aspect of the decision problem. To overcome these limitations, we proposed in this research, a methodological approach for integrating multicriteria analysis in OLAP systems. Our aim of this approach is to create a hybrid model of data (OLAP / MCA), which will expand the capabilities of OLAP through the contribution of MCA as a tool for multi-criteria analysis. In order to validate our contribution, we present the results of experiments showing the efficiency and performance of our approach.
