Spline approximation of economic data using minimax approach

Adoption of effective management decisions often involves the need to analyze large amounts of heterogeneous, poorly structured and noisy information. Therefore, urgent task is creation the decision support system, which allows elaborating rational strategy, even in the face of heterogeneous information, and unsustainable trend. In article developed numerical method and algorithm of solving the problem of approximation data by polynomial splines using minimax optimization criterion. By this algorithm the decision support system for finite number of iterations obtains unambiguous result and generates rational proposals to the decision maker.

Key words

decision support system, interval data, unsustainable trend, minimax, approximation, splines
