Résumé. La vocation d’un entrepôt de données est l’analyse de données pour l’aide à la décision dans les entreprises. La modélisation multidimensionnelle est la base des entrepôts de données et de l’analyse en ligne (OLAP). Ces techniques sont efficaces pour traiter les données simples numériques, mais elles ne sont pas adaptées aux données variées et hétérogènes provenant de différentes source...

Abstract-The analytic hierarchy process (AHP) provides a decision maker with a way of examining the consistency of entries in a pairwise comparison matrix and the hierarchy as a whole through the consistency ratio measure. It has always seemed to us that this commonly used measure could be improved upon. The purpose of this paper is to present an alternative consistency measure and demonstrate ...

Integrating continuous spatial data into SOLAP systems is a new research challenge. Moreover, representation of field data at different scales or resolutions is often mandatory for an effective analysis. Thus, in this paper, we propose a logical model to integrate spatial dimensions representing incomplete field data at different resolutions in a classical SOLAP architecture.

Résumé — les systèmes OLAP facilitent l’analyse en offrant un espace multidimensionnelle des données que les décideurs explorent interactivement par une succession d’opérations Olap. Cependant ces systèmes OLAP sont élaborés pour un groupe de décideurs ou un sujet d’analyse « subject-oriented », pour lesquels sont présumés des besoins parfaitement identiques. Ce qui les rend mal adapté à un usa...

According to the competence-based theory, firm competencies are derived from capabilities that are unique in marketplace and are closely knitted within various business functions across the company. This paper provides a structured framework for evaluating the competencies of a firm using the Analytical Hierarchy Process (AHP). One distinctive feature of this framework is that a multi-criterion...

Droplets containing RNA and Mg(2+) were generated in microfluidic channels. By integrating a group of pneumatic valves and phase separation channels in the microfluidic system, the rapid RNA-Mg(2+) binding kinetics was studied by measuring the Mg(2+) ion concentration using an ion-selective electrode.

The College of Commerce and Finance at Villanova University sponsors an annual research aw^ards program. Its objectives are to encourage and reward faculty research efforts. The process of selecting papers to win the award turned out to be far more complex than we initially expected. After many unsuccessful attempts at developing a manageable procedure, we used the analytic hierarchy process to...

A developing country like India encounters challenges like exponential increase in population and rising per capita energy consumption which demands an optimum usage of available energy resources. Currently the energy demands are mostly met by non renewable energy sources, a system that puts a tremendous pressure on the economy and causes a serious threat to the environment, flora and fauna. He...

The management of development processes is a challenging task and needs adequate tool support. In the course of a development project, many different engineering and management processes are enacted and have to be controlled. The management data has an inherently multidimensional character. Most project and process management systems fail to present large multidimensional datasets in an adequat...
