The algorithms of close methods of decision of one level multidimensional task of unitization are considered in the paper. The ground of the algorithm of selection of variables, using close algorithms, is given. Exactness of the got decisions found by means of the algorithm of selection of variables is well-proven. Efficiency of the algorithm is investigational.

In the enterprise management the important components are the analysis and the activity planning and the analysis process is combined with the forecasting of the progress of the various processes. For solving this class of problems the economical and mathematical methods became widespread, these methods allow to model the complex situations, to state their value, to predict the processes, to plan the activities, to identify the patterns, to uncover the cause-and-effect relations between the objects and the phenomena. The authors present one of the approaches in the forecasting the process of making the administrative decisions.

The analysis of the perspective ways of increasing the effectiveness of information systems on the example of the automated system of monitoring of ecological situation in the region. An approach to the construction of efficient it-infrastructure on the basis of the establishment of centers of processing and storage of information and its optimal placement in a computer network. Formulated the task of the optimal placement

The article proves the relevance of the application of methods of decision-making on the basis of economic-mathematical modeling. It is shown, that application of economic and mathematical methods al-lows to considerably enhance the quality of strategic, tactical and current planning, to receive the additional effect without the involvement in the process of additional resources
