Approach to integration SOLAP tools and multicriteria analysis for spatial decision support

Currently, most spatial decision support systems are based on models that take into account one criteria functions representing the preferences of decision makers. However, they are often faced with complex situations. Since only one function cannot adequately capture all the information necessary for the decision making process, it is natural that we consider the MCDA (Multi-Criteria Decision Analysis) as a tool for integrating multiple decision criteria. The MCDA suggests methods that provide the ability to accommodate a variety of conflicting factors. In this paper, we propose an approach of decision making support that is based on linking the MCDA to the SOLAP process (Spatial Online Analytical Processing), an essential component of the spatial decision support systems analysis. The testing of SOLAP process demonstrated that there exists a shortage in the consideration of the multicriteria aspect. Therefore, it is imperative to integrate multicriteria decision analysis for the expansion of the capabilities of SOLAP process in order that we could make the right decision.
