ENGINEERING METHODOLOGY FOR JUSTIFICATION OF RESOURCE-SAVING SUPPLY OF PARTS FROM SCRAPPED UNITS
Description
This article discusses a method of improving the reliability and efficiency of technological systems of grain harvesting by creating a resource-efficient stock of parts from scrapped units. We consider the theoretical background to the calculation of resourcesaving supply of parts and components from recycled aggregates. The four conditions under which the multinomial distribution law c a sufficient degree of accuracy is reduced to other mathematical models. To assess a working hypothesis, a study was conducted of the accumulated frequencies of the ratio of change of the COP predominant item of consumable spare parts (HRA) to 9880i combine harvesters SNS (John Deere), CR-9060 (New Holland) and RSM-181 "Torum-740". To check the working hypothesis we also studied data on the failure of structural elements Lexion 580 combine harvesters in operation in the farms of the Krasnodar region

Description
In the article, we present existing approaches to the study of the optimal composition of technological systems. We have justified a new method of improving the reliability and the efficiency of technological systems of grain harvesting based on application of mass service theory. An engineering methodology for the substantiation of structure of the technological complex of agro-climatic conditions has been developed. In this case, the basis is the method proposed by S. D. Shepelev and G. A. Okuneva. To justify the structure of the technological complex of agro-climatic conditions of the Krasnodar region we have developed a mathematical optimization model, as criteria of which the losses from downtime of combine harvesters and transport vehicles have been taken. On the basis of the developed technique co-dependence on the number of combine harvesters «Torum-740» from the capacity of vehicles and coefficient for their use for the Northern zone of the Krasnodar region has been found

PREDICTIVE EVALUATION OF THE EXPECTED RICE YIELD IN THE KUBAN REGION IN 2016-2020
06.00.00 Agricultural sciences
Description
The article presents the analysis of variation of daily mean temperatures for the period 1977-2015. Clear tendency for their increasing in pre-sowing and especially in growing period is found. Heat supply of separate months in pre-sowing period increased in the row: April-February-January-December-March, and that of growing period – in a row: May-Juny-JulySeptember-August. Presence of slight correlation (from -0,256 to 0,268) of temperatures in winter-spring months with heat supply of coming spring summer months is found. It is shown that correlation of rice yield with temperatures of pre-sowing (DecemberApril) and growing (May-September) periods varies from weak to average (from 0,016 to 0,524) with a tendency to increasing from winter months to summer ones. Use of analog method made it possible to estimate roughly the nature of t upcoming growing season of rice in the current 2016: after the abnormally warm winter one should expect the value of heat supply of summer months to be close to normal. In the physiological sense, such distribution of summer temperatures is favorable for rice. Use of one of the most effective forecast methods – smoothing the time series (method of «moving decades») – made it possible to evaluate medium-term rhythms of heat supply of rice growing season and yields. It was found that after an abnormally high level of heat supply of the growing season, marked during last decade, we should expect a decrease in spring and summer temperatures - the next attack of the "cold" cycle. If this hypothesis is confirmed, then up to 2020, and later a natural tendency for decrease in rice yields, arising from the adverse factors of temperature, will continue which should also affect the economic efficiency of the industry as a whole

UTILIZATION OF RICE STRAW BY CHOPPING AND SPLITTING WITH A POST-BLADE CYLINDER
Description
The article focuses on the utilization of rice straw by chopping and splitting with a post-blade cylinder. The amount of rice production and rice straw in the Krasnodar region are specified in the article, as well as methods of utilization of non-grain part of rice harvest of rice, namely, burning in the field and use of rice straw as an organic fertilizer. The article describes a research on determination of the degree of rice straw humification under natural conditions at different parameters of its crushing and patching. According to the experimental results there was constructed a graph of the degree of rice straw humification by variants of the experiment. There was offered the projected constructive scheme of mobile trailer rice straw crusher from rolls in the article. The main results which were obtained to the present moment were shown in conclusions

EXPERT METHOD OF FACTOR ANALYSIS OF OPERATIONAL RELIABILITY OF COMBINE HARVESTERS
05.20.00 Processes and machines of agroengineering systems
Description
The article reveals the main empirical factors that increase the efficiency of technological systems of grain harvesting. The work shows interrelation and subordination of empirical factors in the practice of operational reliability of grain harvesters, which underlies scientific research. We have defined the basic (key empirical factors) that allowed to develop a conceptual model (paradigm) research. The article reveals a technique, establishing the rules of application of the method of expert assessments to identify organizational and technical factors that have the most significant impact on improving the reliability of grain harvesters
