Abstract

Decision support systems (construction, real estate, facilities management, etc.) created in Lithuania are described in this paper. The above decision support systems comprise of the following constituent parts: data (database and its management system), models (model base and its management system) and a user interface. Presentation of information in databases may be in conceptual (digital, textual, graphical, photographic, video) and quantitative forms. Quantitative information presented involves criteria systems and subsystems, units of measurement, values and initial weight fully defining the variants provided. The databases were developed providing a multiple criteria analysis of alternatives from economical, legislative, infrastructure, social, qualitative, technical, technological and other perspectives. This information is provided in a user-oriented way. Since the analysis of alternatives is usually performed by taking into account economic, quality, technical, legal, social and other factors, a model-base include models which enable a decision maker to carry out a comprehensive analysis of the variants available and make a proper choice. These systems and the related questions were analysed the paper.
