  OPTIMIZING THE EFFECTIVENESS OF DIRECT MARKETING CAMPAIGNS USING DATA MINING

  In this article several data mining models, together with the conventional RFM model, are designed and applied for optimizing the effectiveness of direct marketing campaigns. Regardless of its popularity as a means for generating “optimal” target lists, RFM analysis is far from optimal solution. Applied on empirical data for one-year activities of ... In this article several data mining models, together with the conventional RFM model, are designed and applied for optimizing the effectiveness of direct marketing campaigns. Regardless of its popularity as a means for generating “optimal” target lists, RFM analysis is far from optimal solution. Applied on empirical data for one-year activities of an e-shop of electronic and home appliance technique, all data mining models surpass RFM model in predictive performance.

  INVESTIGATION OF THE RELATION BETWEEN EXTERNAL COSTS AND ECOEFFICIENCY

  The development of reliable methodologies for assessing the harmful effects of production and consumption of goods and services on the environment is a major challenge to the scientific community.

The development of reliable methodologies for assessing the harmful effects of production and consumption of goods and services on the environment is a major challenge to the scientific community. Along with the existing indicators, indexes and other measurement tools, in recent years relevant quantitative methods for evaluating these influences have become increasingly popular and much used. By increasing the reliability of these methods the topical question of how they are integrated into the assessment of eco-efficiency of goods and services has been put forward. The aim of this project is to offer a scheme using external environmental costs in the evaluation of eco-efficiency. For that purpose, after a detailed analysis of the results taken from various sources, this project offers the basic steps of the integrated circuit, as well as different approaches for assessing eco-efficiency at macro level, and the software used for this purpose and support systems for decision-making. Computations have been performed and concrete results have been obtained.

  ANALYSIS OF TOURISM CLUSTRS DEVELOPMENT

Developments in the formation and functioning of the Bulgarian clusters are in its initial phase. Strongly supported by the state these business units increased rapidly in number. However, such issues arise as: “How clusters should be actually working in our economy?”, “In which sectors should be exercised influence in the direction of support clusters?” “Really bunches of companies are suitable model a competitive economy?” etc. The answers to these and other issues related to cluster will be received in the future. The fact is that in world practice, such entities are carried out, realized and will likely give very good economic and social outcomes, leading included enterprises and regions in which they operate, to economic prosperity. This project is a continuation of several previous studies concerning clusters on one side and tourism on the other. It comes to meet the scientific “intersection” of two research teams – those from the Departments of Industrial Business and Entrepreneurship and Commercial Business. Data collected by the project indicate many diverse processes in the field of clustering in the most attractive economic sectors in Bulgaria - tourism. They promise “interesting times” for those in clusters and for the policy-makers.
