Метод спрощення задач користувача на інженерних порталах знань

The paper presents the approach engineering tasks execution on knowledge portals that can be used to increase the efficiency of such tasks performance. The method of engineering tasks simplification is proposed that allows to form the minimized set of engineering tasks elements used for such tasks execution. Specific algebraic system of engineering tasks is described that form the basis for method of engineering tasks simplification. Algebraic system involves formal contextually independent structures for engineering tasks elements representation. The example of the approach usage for real engineering tasks is depicted, the quantitative evaluation of the efficiency increasing for engineering tasks of “Strength of materials” problem domain is given.
