The Development of the School of Spatial Analysis of W.Isard on the Basis of Economic and Supply Chain Management Models of the Petrochemical and Chemical Production Cluster

Abstract- In the first post-war decade, studies of the problems of the regional economy were developed in many countries based on the supply chain management. Prerequisites were created for the unification of regional scientists and a new attempt to synthesize theories of spatial and regional economics. At this stage, the avant-garde role was played by an American scientist, W. Isard.Hi is first major monograph, “The Placement and Economics of Space,†was published in which he posed the problem of eliminating the deep discrepancies that exist for more than 100 years between classical theories; accommodation and leading schools of general economic theory.W. Isard rightly criticizes all classical and neoclassical economic theories for the fact that they limited themselves to studying "a country of miracles devoid of any spatial characteristics." This was partly due to the classical placement theories, which were expounded in outdated language and with excessive simplifications of "partial equilibrium", constant coefficients, cost minimization, constant demand curves, etc. Overcoming the stereotypes of these theories, W. Isard will clothe the theory of locating production in a more general economic form. He deduced the following law: profit maximizing firms will be located; so that the marginal rates of replacement of transportation costs of goods from two different points (regions) are equal to the reciprocal of their transportation tariffs. From this condition of the first order of maximizing profit, one can derive all particular allocation theories (Tyunen, Launhardt, Weber, etc.). Further, W. Aizard links, where it is possible, the theory of location with the known theories of production, pricing, trade, etc

Digital Modeling of Economic Processes and Supply Chain Management in the Formation of Cooperative Relations in the Petrochemical Cluster of the Region

Abstract- A study of the state of the theory of fuzzy sets shows that until recently in Russia there were almost no studies in the chemical sector of the economy and finance using fuzzy analysis and forecasting, although by that time all necessary prerequisites for modeling financial systems had been created. The current situation in Russia is characterized by a high degree of science lagging behind the requests of state and commercial supply chain management.Fuzzy sets have not been used to date for financial analysis and planning of chemical corporations, evaluating the investment attractiveness of securities, optimizing the stock portfolio, forecasting stock indices and macroeconomic indices. You can also talk about the lack of software based on fuzzy models, although abroad, such software products and information technologies that solve economic problems using fuzzy-plural and related descriptions already exist.In the 80's, software solutions and information technologies began to emerge, solving economic problems using fuzzy-plural and related descriptions. Thus, under the leadership of C. Zopounidis at the Technical University on the island of Crete, an expert system was developed for detailed financial analysis of corporations. A little earlier in Germany, a group led by H. Zimmerman developed a strategic planning system, in which the positioning of the corporation's business is based on fuzzy descriptions of the competitiveness and attractiveness of the business.As an example of such software, you can use expensive complex systems, which include fuzzy logic, which bankers and financiers use to solve the most complicated problems of forecasting financial indicators. The beginning of this process was laid by the Japanese financial corporation. Having set out to automate the game on the securities market, this company attracted about 30 specialists in artificial intelligence

Оцінка фізичного здоров’я курсантiв

Міжнародна науково–практична конференціяВажливе значення для оптимального функціонування організму курсантів, ефективного засвоєння ними знань, умінь та навичок має належний стан здоров’я, який одночасно є інтегральним показником благополуччя суспільства і чутливим індикатором соціальних та екологічних негараздів

Мотиви до занять фізичного виховання курсантів першого курсу.

Всеукраїнська науково-практична конференціяПроблема формування мотивації одна з важливіших умов успішності у досягненні результатів. Мотиваційний компонент приховує в собі великі можливості. Як свідчать дослідження психологів, мотиваційна сфера більш динамічна, ніж пізнавальна та інтелектуальна. Але відносна динамічність має позитивні і негативні сторони. І якщо нею не управляти, то може бути регрес мотивації, зниження її рівня і взагалі може бути втрачена дієвість. Формування мотивації часто йде стихійно і дуже рідко є предметом цілеспрямованої систематичної роботи. Складність вивчення мотивації і тим більше формування її, пояснюється перш за все тим, що на курсанта діє одночасно комплекс мотивів, які не лише доповнюють один одного, але й вступають в суперечност

Visible and IR Photoluminescence of Erbium Doped Porous Silicon Films

Two different oxidized porous silicon samples were saturated with lantanum oxysulfide luminophors doped with Er and Yb from their colloidal alcoholic solutions. One of the samples was annealed at 700 degrees C for 10 min, another was heat treated at 100 degrees C for 6h, After annealing, both exhibited room-temperature Er3+ photoluminescence which increased significantly under excitation at wavelengths corresponding to the absorption band of porous silicon. In addition, the sample containing the largest amount of Yb3+ revealed a strong Yb3+ photoluminescence at 985 nm
