INNOVATIVE-TECHNOLOGICAL PREREQUISITES OF GRAIN COMPETITIVENESS IMPROVEMENT

abstract 1321708020 issue 132 pp. 249 – 264 31.10.2017 ru 640
The systemic links that depend on mechanization, which affect the growth of the cost price of field crop production were proposed and their analysis was made. Three main blocks of the basic reasons for production costs growth (machinery and materials cost rise, agroecological potential underutilization, agrotechnologies non-observance) disclose agricultural machinery and agrotechnologies of field crops negative aspects that are being used, and also explain agro-potential underutilization causes on the example of the Krasnodar region. The irrational nomenclative list of machines in the current system was analyzed, which not only raises field crop production cost price, but also negatively affects the soil fertility due to its reconsolidation and spraying. Requirements for production processes mechanization means, taking into account their cost price reduction, were formulated. The possibilities for optimizing of the field works timing performed by the proposed agricultural machinery, their quality improving and product damage reducing, as well as work complexity with coinciding terms, streamlining and rhythmicity of processes were formulated. Taking into account the system approach, the imbalance between the agro-industrial complex and management forms was reflected in the weak interrelation of their interests with state interests, which also affects the cost price of production. The negative aspects of the machine system for the mechanization of field crop cultivation were revealed. A special effect should be expected from the proposed combination of technological operations in one pass of the machine across the field due to full-scale adaptations to machines, the ratio of the park of caterpillar and wheel tractors and the work complexity. On the basis of these studies, proposals for traumatization reducing of grain by harvesting equipment and the cost of crop losses from trauma, as well as the regularities of the area of damage to grain from grain vitality have been substantiated. The reasons of production cost price increase are connected with attracting investment issues and managing innovative activities of introducing priority means of mechanization (concessional lending, subsidies, etc.)

The article is devoted to increasing beekeeping’s earning capacity with rigging and automation of technological processes. Winter is the most complicated and critical period in beekeeping. It influences on further productivity of bee colony. Winter period has specificity – bees are gathering in winter cluster and sustaining temperature in 24…32 °С range inside. This temperature is depending on fluctuation of outside air temperature. For passing winter without complication electric heating is used. Cluster geometry in winter is changing constantly and for optimal regime of electric heating we need to take it into account. Additionally, bees’ activity changing beehive’s microclimate and it’s important to know when beehive’s microclimate adaptive control system is developed. Conducted researches allow us to get basic equations which characterizes microclimate with taking into account of winter cluster’s variable geometry. The equations establish linkage basic parameters of beehive, winter cluster, internal air between outdoor air. Simulation results may be used for adaptive heating control system programming.

RISK MANAGEMENT IN WOODWORKING

abstract 1321708053 issue 132 pp. 645 – 654 31.10.2017 ru 408
The article deals with urgent questions concerning activities of woodworking industries, which face tough economic situation. Nevertheless, these enterprises reveal a definite growth of output in some kinds of products, such as fuel pellets, window units, special timber assortments, etc. The problems about possible risks connected with equipment handling were identified, which has physical and intellectual wear, as most of it has been operating since 1980. On the basis of accomplished investigations of normative and technical sources the documents were specified, which establish safety regulations for operating equipment and requirements for risk assessment techniques. The necessity of their improvement is also determined. Taking into consideration peculiarities of management of woodworking production process, the analysis was carried out in order to estimate the factors, which influence the quality of mechanical treatment by the method of 5M. Following the observations and processing of statistical data it was established that equipment and personnel show the greatest impact on the quality of half-finished and final products. Risks evaluation method for woodworking industries is suggested with due account for equipment safety parameters, which includes determination of consequences, risk probability, risk level on scale factored “high”, “medium” and “low”. Much attention is paid to the items composed: rank matrix of two-factor model, with calculations of numerical values of risks, as product probability of occurrence and severity of consequences, and risk log. Three zones were appointed with the following risk levels: the first zone with weighting factor not less than 6, the second zone: 8-16, the third: 20-25. In course of investigation, it was detected that the highest risk factor, connected with equipment operation, is probability of mechanical injuries of hands and most possible – getting cuts. The flow chart of risks management during the woodworking production process is offered in accordance with all Union State Standard regulations R ISO 9001-2015 and GOST R ISO/MAC 31010-2011. The developed algorithm provides accomplishing performance of work on risks management in more available and short form with presentation of processing operations, actual doers, kinds of required normative documents and papers worked out within the enterprise
