Description
The article describes the process of developing the two-level technique for assessment of the missed benefit during the landing and cultivation of perennial plantings. The technique is developed for the enterprises where the cycle of production of raw materials breaks into several periods until the first harvest. The choice problem of the most suitable grades for the landing is relevant for such enterprises. The first level of the two-level technique assumes assessment of qualitative and quantitative characteristics of grades with use of such tools as the theory of fuzzy sets and the decisions tree. The results of the first level are entrance data for the second level where there is final assessment of a grade and determination of the missed benefit rather potentially possible at the choice of the recommended grade. In the article also designated the importance of the raw materials stage for the technological chain. It is shown that, being consecutive structure, the technological chain strongly depends on the first stage – a stage of raw materials production. Minimization of the risk situations at the first stage promotes strengthening of the general risk tolerance of a technological chain

Description
In the article, the problem of a performance evaluation of activity of municipal unions in the field of guardianship and guardianship is stated and its solution, based on application of system-cognitive analysis and its tooling ("Eidos" intellectual system) is offered. The formal problem definition and data domain formalization are fulfilled, i.e. classification and descriptive dials and their graduations are elaborated, the training sample, according to 2009-2010, is generated, synthesis and verification of four cognitive models, different by private measure of knowledge, which extend and formalize modes of a decision making of experts in the previous phase are performed. Framed models are applied to the computerized performance evaluation of operation of 43 municipal unions of Krasnodar territory in the field of guardianship and guardianship for 2011 and have yielded such outcomes of an estimate, which would be gained by experts as well, under condition of immutability of their approaches

SOFTWARE SYSTEM FOR ANALYSIS OF FLOW DIAGRAMS IN THE PRODUCTION OF AGRICULTURAL COMPANIES
DescriptionThe article describes a software complex which allows carrying out computer experiments in the study of economic efficiency of integrated production structures in agriculture and their stream of interaction. The article provides software used in complex mathematical ratios and their machine algorithms implementation. The authors have given a detailed description of the user interface with graphic examples. The application is written in programming language C#. This language was chosen for several reasons. The first reason is of course that C# is cross-platform that gives you the opportunity to use this app on any platform, and plays an important role in research activities. The final decision was influenced by the fact that in C# is implemented for working with charts, using standard library chart that provides a significant advantage compared to other programming languages during the development of the software complex

OBSTACLES TO THE ESTABLISHMENT OF EFFECTIVE ASSOCIATIONS OF THE ENTERPRISES OF A DAIRY SUBCOMPLEX
DescriptionThe article analyzes reasons that prevent the formation of stable and effective AIC associations of commodity businesses and processors of raw materials. Unbalanced process of the relationship between agricultural producers and processing plants have a negative impact on the economic situation of the organizations partners. Dictating low purchasing prices for raw materials by processing enterprises hinders profitability of agricultural producers. Purchase prices set by the processing enterprises of the dairy industry for milk, do not compensate for not only the production costs but also the losses from inflation. The rate of growth in energy prices is significantly higher than for livestock products, bringing its cost grew faster than sales prices. This leads to a dramatic reduction in milk production profitability. A paradoxical situation: on the one hand, dairies are facing an acute shortage of raw materials, on the other - exacerbated the problem of the sale of its milk producers at a reasonable price for them. The disparity between the purchasing prices for milk and retail prices for dairy products caused agricultural companies to seek alternative markets. Sharply increased sales of milk in the bottling of milk tankers, while many farms began to create their own recycling system

APPLICATION OF ACOUSTIC-MAGNETIC DEVICES IN HEAT SUPPLY SYSTEMS OF GREENHOUSE COMPLEXES
05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
DescriptionThe article discusses scale formation problems of greenhouse complexes with geothermal heat sources. Two-circuit geothermal heat supply systems with intermediate heat exchangers are used to prevent equipment and communications scale. Fresh softened water is heated by geothermal heat and is supplied to consumer needs. The heat exchanger and primary circuit communications contacting with the geothermal heat carrier (geothermal water) are subjected to scale formation in the existing system. A scale formation of heat exchange surfaces reduces the efficiency of the heat exchanger and requires a periodic cleaning and causes a chain of economic losses in the production, transportation and consumption of heat. Currently, we use physical, chemical, biological and combined methods of scale formation prevention. The article also considers hypothesis about the effect of an acoustic-magnetic field on solutions. It was found experimentally, that the acoustic-magnetic field affects to characteristics and dimensions of salt crystals. The number of particles increases and solid phase dimensions decrease. A large number of microcrystals suspended in water are formed as a result of the nonchemical acoustic-magnetic treatment of geothermal water. These crystals do not stick to the pipe surface and do not settle to the bottom, may be filtered out and carry out by water flow from the system
