OPTIMIZATION OF OPERATION AT THE FOUR HARROW
DescriptionDisc tools are designed for the surface treatment of the soil, as well as for loosening and preparing the soil for planting, weed control and grinding residue, for seedbed preparation without preliminary plowing in the system of minimum tillage technology and after thick stem row crops harvesting. It implements a disk type implements include a disc mounted on the individual rack. Classical instruments of this type are made with a rigid stand mounting the cutter body to the frame. In the classical working body attachment scheme has a number of disadvantages. One of them is the lack of a safety element. The proposed version of the working body of the fastening using a spring strut has the following advantages. When zooming in on the disc obstacles (dense soil, bump, pit, stone), flexible disk drives backward, up, down or to the side (left, right) by the spring property (elasticity) of the curved rack. This design reduces the shock load on the bearing assembly, wherein the disc is returned to the original position by passing earth and crop residues without blockage. The purpose of structural changes was to reduce the energy intensity of the surface treatment process of the soil while improving reliability

OPTIMIZATION OF COMPOUNDING OF SAUSAGE PRODUCTS IN THE CONDITIONS OF REAL TIME
DescriptionThe growth of profitability is the main task of any company. Having faced low purchasing capacity of consumers, and also with shortage and the high price of raw materials, manufacturers of meat products not to be ruined, are compelledto reduce percent of the maintenance of meat. Thus it is necessary to optimize a compounding for preservation physical, chemical and organoleptic properties of a ready product. For these purposes, various software products are used. In the article we present the analysis of the work of the ОPТIМIТ program

Description
Using queuing theory (QT) for the new technology of harvesting of grain crops by the method of «Neveyka», the method of optimal designing of maintenance system and elimination of failures of units used in cleaning technology and post-harvest processing of grain has been considered. On the basis of a systematic approach, taking into account the probabilistic nature of the change of operating factors the methodical directions of validity test of the adoption of the Poisson distribution in the calculation of operating modes were substantiated to optimize maintenance level units and eliminate failures in the operation of the machines, the probability of failure-free operation of harvesting and transport aggregates. The probability of failure-free operation of each type of units used in the cleaning of grain depends on their number and intensity of service. According to the numerical value the probability of failure-free operation of units is equal to the probability of idle units for maintenance and elimination of failures. Since it is impossible to determine separately the value of the probability of failure-free operation for all types of units and all kinds of services at different operating conditions the generalized solution has been offered, this solution is applicable to any serviced unit during both the technical inspection and elimination of failures. By specifying the desired value of the probability of failure-free operation of harvesting units, according to their number we can determine the appropriate ratio between the average length of service and the average period of time between incoming service requirements (technical inspection and elimination of failures) from one unit

Description
We have considered hybrid nontraditional and renewable sources of energy in terms of optimizing their work based on the knowledge of technical and functional peculiarities of each. We used classification of clusters of nontraditional and renewable energy of sources, depending on the proportion of replacing power in energy consumption and on the type of nontraditional and renewable energy of sources. We examined a simulation model of the hybrid cluster using the structural diagram and performed statement of the problem by means of the full and multifactor experiment. We applied the method of analysis of non-stationary random process disturbing influences
