At national, regional and global scale, grain production will be of growing importance in relation to feeding the population and the production of biofuels. The economic and statistical survey of production costs in grain production gives opportunity to find reserves to reduce them to their optimal values, to reduce the unit cost and to increase the profitability of grain production. Part of the information used in the study is taken from official statistical publications, and the main body of data on production costs of grain production has been gathered from a questionnaire conducted among grain producers from Veliko Turnovo district. A number of statistical research techniques have been used in the present study – graphical and tabular methods, correlation analysis, representative method, average and relative values, index factor analysis and other.

The realization of the instrumentation of technical analysis has been applied intensely in the field on the one hand and has suffered a relatively vague realization in Bulgarian academia on the other. This research paper focuses on the fundamental techniques of quantitative analysis that make possible the forecast of fluctuations in foreign currencies quotations. The former relates to the main purpose of the current paper – to analyze the fluctuations in the market trend on the currency market and to reveal the potential of this specific approach to optimize the speculative decisions market players make. In order to achieve this purpose the following issues need to be resolved: systematization and characterization of the fundamental theoretical concepts on which contemporary analytical techniques are based; quantitative analysis of the market trend involving calculated indicators which include the basic price prerequisites.

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.
