DEMATEL : A Methodology for Research in Library and Information Science

For different composite issues and factors on a complicated problem, there is a need to structure the problem with analyzed casual inter-dependency and influences with graphical illustration. In this paper the authors are explained the Decision-Making Trail and Evaluation Laboratory (DEMATEL) methodology, kind of different problems for which DEMATEL can be used and the method of the approach with steps. To solve complex and intertwined problem group this approach is proposed. It is capable to verify inter-relationship between the factors and offer a specific chart to inter-relationship. It is based on the technical experts’ opinion and they plays complementary role. Direct influenced matrix clarified the key factors and specifies the priorities of the factors.
