МАТЕМАТИЧЕСКИЕ МОДЕЛИ ТОВАРНОГО РЫНКА

The article describes enterprise mathmodels, its interactions with environment in commodity market and quantitativeconditions for its success and the crisis in such kind of interaction. Showed: the number of commodity market successfulparticipants should be certain, regardless of market size; any size commodity market, including monopolistic, is assuccessful as producers’ average activity dynamics is balanced with consumers’average activity dynamics.Статьяописываетматематическиемодели предприятия, их взаимодействия с внешней средой и количественные условия их успеха и кризиса в этом видевзаимодействия. Показано: число успешныхучастниковтоварногорынка должно быть определенным независимо от его размера; товарный рынок настолько успешный, насколько динамика производителей сбалансирована с динамикой потребителей

On Some Problems of the Economic Education

In this article key problems of ensuring of historical component in training of economists and managers as a whole and separate economic subjects specifically are discussed.

Morphological features and mechanics of destruction of materials with different structures under impact drop cyclic loading

The process of erosion destruction of steels with austenitic, sorbitol and martensitic structure under the influence of high-speed liquid-drop collisions is studied. The characteristics of the morphological features and mechanisms of the process of surface degradation of steels with different structures are given. Their classification criterion is proposed on the basis of the diagrams of limiting states. Based on the theory of Paris-Erdogan, the computational and analytical model of the fatigue fracture of martensitic steel has been developed
