When making choices and decisions, very seldom does the situation arise that a decision-maker very seldom bases their assessment of the options available on only one criterion. Frequently, many aspects of the available solutions are considered – both in terms of potential benefits and costs. In order to support decision makers, the Multiple-Criteria Decision Analysis (MCDA) is used for selecting the solution which is the best in several respects. There are many methods of multi-criteria decision-analysis such as AHP, ELECTRE, PROMETHEE, VIKOR or TOPSIS. In the article a modification of the last of these methods is used. With the use of TOPSIS method with interval arithmetic the analysis of the level of information society (IS) development in the European Union countries between 2005 to 2010 is performed and its results are presented.

Information sources are considered a catalyst for innovation improvement, and because of this it is particularly important to learn more regarding their impact on innovation performance. Therefore, the goal of this research is to investigate to what extent the usage of different information sources influences internal and external R&D activities in three countries, Croatia, France and the Netherlands, by employing CIS data, which covers the period from 2006 to 2008. These countries were chosen because of the different levels of their country competitiveness (measured by the Global Competitiveness Index), which permits us to investigate if the usage of information sources has varying impact on their innovation performance. Our results reveal that internal sources, customers, suppliers and universities are important information sources for both internal and external R&D activities in all three countries. However, significant differences are also found. Firms from the Netherlands (which has the highest country competitiveness) use information sources differently, relying on competitors as one of their most important sources of innovation. On the other hand, the government did not have any impact on firms in Croatia (which has the lowest country competitiveness), indicating that this may be the reason for similar countries lagging behind.
