Inventory management (in other words, logistics) is an integral part of the work of firms, companies and organizations. We are talking about stocks of raw materials, fuel, tools, components, semi-finished products, finished products for industrial (or agricultural) firms, about stocks of goods to distribution centers, warehouses, shops, workplaces sellers, finally consumers. Stocks spent all the time and supplemented on various rules adopted in the firm. Optimization of these rules, ie, optimal inventory management, gives a big economic effect. The mathematical theory of inventory management, based on the models of movement of flows of goods, is an important area of economic-mathematical research. The classical model of inventory management proposed in 1915 by F. Harris is one of the simplest and most illustrative examples of application of the mathematical apparatus for decision-making in the economic field. This model is commonly referred to as the Wilson model, because this model became known after the publication of R.G. Wilson in 1934. The formula of the optimum batch size (the so-called "the formula of the square root"), obtained in the Wilson model, is widely used on various stages of production and distribution, since this formula is practically useful for decision-making in the inventory management, in particular, for generating significant economic effect. However, contrary to popular belief, by means of this formula it is impossible to calculate the optimal batch size (although it is a necessary step on the path of its finding). In strict economic-mathematical analysis of Wilson model, conducted in the article, it is shown that the formula of square root does not give the optimal batch size. We have given the algorithm for calculating the optimal batch size. It has been found that the formula of the square root gives asymptotically optimal plan. We have studied the stability of the conclusions in the economic-mathematical model and considered an example of the practical application of the classical model of inventory management
In this article the basic principles of air-fuel mixture explosions and striking factors, such as air-striking wave, gas streams, splinters, flame heat, light radiation and sharp sounds are observed. The calculation technique of the emergency emission consequences which is for a quantitative estimation of air-striking wave parameters at air-fuel mixture explosions forming in the atmosphere at industrial failures is given. The basic structural elements of calculation algorithm are listed. It is supposed partial depressurization or full destruction of the equipment containing combustible substance in a gaseous or liquid phase, the emission of this substance in the atmosphere, the air-fuel mixture cloud formation, the air-fuel mixture initiation (ignition) and the explosive transformation (deflagration or detonation) in the air-fuel mixture cloud. The technique allows making the approached estimation of air-striking wave various parameters and defining the probable degrees of men defeat and building damage at failures with air-fuel mixture cloud explosions. The given technique is developed in C# language in the integrated environment of software Microsoft VisualStudio 2010 working out. The program fragment in which the calculation of dimensionless Px pressure and dimensionless Ix impulse is given
The article presents the research results of the impact of amendment improving soil structure on soil upon sprinkler irrigation of agricultural lands. It is proposed to use artificial aggregation of soil for water erosion control via composition of structure-forming materials. The developed composition includes slagheap rock, bentonitic clay, claydite screenings, and shell limestone. Adjusted analytical relations of the impact of the amendment on runoff coefficient depending on the intensity of artificial rain upon irrigation of agricultural lands, slope, and water permeability have been revealed. Regression analysis of spectral surfaces has shown that slope of irrigation site has a significant impact on the increasing of runoff coefficient values, while correlation coefficient equals to 0.97. Water permeability has negative correlation, -0.85, with increasing the values of runoff coefficient. The relation between runoff coefficient and intensity of artificial rain is less strong, 0.89. We have determined that applying of the given amendment provides decreasing of runoff coefficient by 15 % depending on the slope of irrigation site, and by 20 % depending on rain intensity. Experts in the field of land reclamation can use obtained analytical relations for predicting surface soil loss when estimating the efficiency of amendment applying to control soil erosion activities at agricultural lands

The article is devoted to the an actual problem of modern management science – to the development of territorially-localized systems on the basis of clustered formations. The Krasnodar region is one of the most developed and perspective subjects of the Russian Federation that because of the high recreational potential is possible of progressive development of the tourist sphere. In the article we have considered the questions of regulatory-legal ensure and organization of development sanatorium and resort complex of the Krasnodar region. We have analyzed the tendency of the development of sanatorium and tourist complex in the region and determined the factors of distorting influence on its development; described the dynamics of the Fund of tourist accommodation; described the mechanism of public-private partnership in the development of the special economic area of tourism development in the territory of the Krasnodar region. We have recommended the project of organizational mechanism management development of competitiveness of the sector on the cluster basis. The article emphasizes the uniqueness of tourist and recreational resources of the Krasnodar region, and besides it distinguishes the main signs of the formed cluster. We have developed a model of factors providing influence on the competitiveness of economic objects of the territorial and localized system in the region. To effectively manage the development and formation of the cluster we have suggested regionalization of the terms of tourist business development and infrastructure. The proposed system of localization of tourist and recreational clusters might promote the development of different types of tourism in the region, mostly-recreational, active and culturally-cognitive. The instrument for the realization of this mechanism is program-target method, which increases the interaction of target programs of development of tourist and recreational areas
The study was conducted in a stationary multivariate experiment at the experimental station of Kuban State Agrarian University during eighteen years. The technology of growing winter wheat was improved by the optimization of norms of fertilizers and plant protection systems for different levels of soil fertility. Totally there were 48 technologies for growing winter wheat after and grain: corn, sunflower, sugar beet, where studied in the experiment. The best combination of high yield (77.2 t / ha) with high quality grain (nature - 789 g / l, the total vitreousness - 60%, -14.2% protein content, gluten content - 29.0%) was found under intense technology. The grain quality meets the requirements for the 2nd class. Similar productivity (yield - 76.4 t / ha, the total vitreousness - 55% protein content - 13.4% gluten content - 27.2%) was obtained in and when grown for its resource-saving technology also. All kinds of technologies for growing winter wheat studied in the experiment were profitable, but resource-saving technology was the most efficient. Net income per hectare under this technology was 31,745 rubles, and a cost of 1 quintal of grain - 284 rubles
In the article we have considered the new valuable reference points of the economy development of Russia characterized by such intrinsic categories as "wealth", "moral" and "happiness". On the subject of the conducted research, there is analyzed the moral position laid down in the Scriptures (in example the «Holy gospel»), the works of A. Smith, K., Marx, J.C. Sismondi, J.B. Say, A. Marshall, J. Stiglitz. Such important contemporary Russian society problems are formulated, such as: the disclosure of the relationship of the national wealth with its spiritual and moral development as an property; the depreciation of the moral values in the unspiritual elite of the society; the purity, the clarity, the innocence origin of the wealth of the every citizen; the grounds for the origin of the inequality in the world and in Russia and scientific stratification; the misconceptions about the correlation of the spirituality and the wealth or the poverty, the expectations of the happiness from outside are identified, the author laws of the morality development in the economics are formulated. Another important issue is the access to the distribution of the natural resources of the country, the distribution between the different members of the society. The main conclusion of the article is that in the economics of the happiness should be set such rules, in accordance with which the individual could become rich through his labour in the process of the spiritual and moral growth. We have used the author's scientific approach of a criteria assessment of the economic development vectors on positive and negative, there are investigated the directions of the improvement of the modern Russian legislation
In the article we bring to light the delusions of the theory of the crises analysis as effectless at the creation of modern systems of the state anti-recessionary regulation. The principal problem is the variability definition of the term of crisis and the vagueness of the date of its start and the ending. The knowledge propagation in the field of the circular economy development is focused in Russia on the N. D. Kondratiev’s works in this area, repressed in the Stalin times. The attention is drawn to the fact that N. D. Kondratyev emphasized that, first, his cyclicity «lacks the preciseness and, of course, admits the exceptions, and secondly, it does not contain the author's explanation of the reasons, and, thirdly, the author saw that the upward waves were accompanied by the major social upheavals and the socials upheavals (revolutions, wars) in comparison of the periods of the downside waves. These circumstances are not taken into the consideration when creating «Kondratiev waves» in the excess long-term (up to 2060 year). The analysis of the development of the scope of anti-recessionary regulation in the operating regulatory legal base of the Russian Federation is performed. The author found that in the Russian legislation there are differs «the large-scale financial and economic crisis», «the crisis phenomena», «the systemic political and socio-economic crisis», «the government crisis», «the budget crisis» and many other types of the crises in the modern Russian economy
Long time in Russia we have a paradox when the law rules are accepted, reconsidered with the different level of the knowledge intensity and the effect for the social development, but the practice works with the essential derogation from the observance of the established legal regulations. In this article the author considers the essence of the most important rules of constitutional law in Russia: the right to the life, a state protection guarantee of the protection of the citizen in different fields, the right to the participation of each citizen in the state governance, the right to the request to the government and local authorities with the purposes of the receiving the effective and timely help, the competent explanations, the right to the work, the state protection of the motherhood and the childhood, the right to the housing, the right to the health protection and the medical care, the right to the recreation and the right for education. We have also set a task of the overcoming of stereotypes of the comparison of the existing rules of the right to their right application and on the example of the analysis of the important standards of the Russian constitution there is drawn the conclusion about the need of the carrying out audit of the observance of the law rules, the formation of the transition from static consideration of the law rules in the dynamic with the carrying out the comparative analysis of their right application corresponding to the different periods of the development
The article subjected to a detailed analysis of the norms of a number of Federal laws, fixing the liability insurance for members of self-regulatory organizations. The author shows the benefits of liability insurance of members of self-regulatory organizations in comparison with another way to ensure property accountability is the compensation Fund of the self-regulatory organizations. It turns out the legal nature of the contract of insurance property liability of the members of self-regulatory organizations, types of property risks in the insurance contract that applies to the members of self-regulatory organizations. It is noted that the issue of liability under contracts of members of self-regulatory organizations in the Federal law "On self-regulating organizations" not resolved, fixed only need to create a personal and (or) collective insurance. In practice, insurance agents offer to insure the contractual liability as liability for injury that, according to the author’s opinion, is not complying with the law, including the standards of article 931 of the Civil Code of the Russian Federation. The issue of the conclusion of the construction contract of property insurance liability of members of self-regulatory organizations is also discussed by the author, as well as the necessity of the using in such a situation the rules of the Law "On insurance" about the contract of financial risks insurance. The necessity of changes and amendments of the current legislation of the Russian Federation on insurance property liability of members of self-regulatory organizations is proved by the author
