STAGES OF PASSAGE PROJECT IN THE ORGANIZATION BY USING ADAPTIVE SYSTEMS SUPPORT OPERATIONAL DECISION-MAKING IN THE MANAGEMENT OF I.T.-PROJECTS

abstract 1201606068 issue 120 pp. 1036 – 1046 30.06.2016 ru 466
The article considers the stages of the passage of the project in the organization. Decision support system facilitates the work of heads of enterprises and enhance its effectiveness. The organization has a system of registration applications, which contains the information about the project, its description, the terms of development, the developer (or development team) and stages of this project. Using the software package, the customer leaves the application to provide services. Head sends a request to the appropriate division. Departments, in turn, transmit information about the status of implementation of the application through a software package. The software package enables fast two-way remote communication in electronic form between the customer and the head, and between the director and divisions. The organization coordinating the work on the implementation of IT-projects by the head and the head of the sector. But there are some human factors, through which people can not keep up with the timely implementation of all tasks given by subordinates. Developed DSS helps to save time in monitoring the project development phase, will eliminate the human factor in monitoring the success of the project, and will assist in the decision-making in cases of force majeure. Development of an IT project consists of several stages, each of which has the ability to give interest characteristic of the total time spent on the project. Supervisor carries out the decomposition of the problem and evaluation of each stage

abstract 1201606071 issue 120 pp. 1093 – 1107 30.06.2016 ru 443
The article contains a scientifically based approach to assessing and improving the reliability of DMU "Frigate" in the conditions of the Rostov region. The studied parameters for the elements with the lowest resource were: mean time between failure, mean time to repair, probability of failure, the parameter flow of failures, failure rate, actual and allowable factors of readiness. The analysis of the main faults of DMU "Frigate", identified nodes and elements, characterized by the low reliability, for which the dependences of probabilities of failure-free operation, as well as the dependence and developed the procedure for calculating the optimal duration of recovery of failed elements, to ensure acceptable availability. Statistics on major faults refuse items were collected over the three irrigation seasons from 2013 to 2015, were investigated failures due to wear of the elements for 17 irrigation machines. As a result of the research we developed mathematical apparatus of calculation and the comparative assessment of the readiness of the parks sprinklers of various farms to perform their processing functions at the same and different number of machines. We obtained the dependence for determining the allowable duration of the recovery elements that will allow you to determine the main directions of improving the reliability of DMU "Frigate" during the operational phase

SOUND EFFECTS INFLUENCE ON THE OPERATOR’S ORGANISM IN PRODUCTION CONDITIONS

abstract 1201606072 issue 120 pp. 1108 – 1120 30.06.2016 ru 411
Here we present a brief survey of noise effects on human’s organism in production conditions, including noise effects on operators of machines and technical devices. It is well known, that any biological organism exists in balance with its environment. However, noise effects being stress factors knock the operator of machines and technical devices out of the working rhythm and cause different kinds of health disorders such as blood pressure increase, fatigue, disorders of the central nervous system and gastrointestinal tract and the like. All this may lead to accident situations, reduction of labor productivity and quality of work. Frequently health disorders start with hearing impairment which leads to disorientation in the threedimension space and malfunction. It is because the hearing apparatus as biological system provides the organism with sensory information and ensures selfpreservation. In the noise conditions, these characteristics are conflict: on one hand, the hearing organ should possess high enabling capability to receive positive signals, and on the other hand, in order to adapt to the sound hearing and sensitivity will decrease. The duration of noise exposure and the number of years spent under influence of the noise are also of great importance. Thus, it is obvious that control of the noise and prevention of harmful effects of the noise on machine operators are important components of production process in the agrarian sector

METHODOLOGY OF ACOUSTIC SAFETY MEASURING IN OPERATORS’ BOOTHS OF AGRICULTURAL MACHINES

abstract 1201606073 issue 120 pp. 1121 – 1135 30.06.2016 ru 440
In this article, we have examined the methodology of acoustic measuring with the purpose to create safety conditions for the activity of agricultural machines operators, in foremost harvesters and tractors. We should underline that such studies are based on the state standards that are aimed at improving the level of comfort of the activity of the operators of tractors and harvesters and maintaining their working capacities. Therefore, there is a need for a thorough analysis of the current regulatory legislation (standards that are applied) in combination with analysis of mathematical support of measuring devices (sound level meter). Besides, there is a need for creating strict sequence of actions of the sound level meter operator (algorithm) in combination with the method of conveying information that is adapted to the experiment. At the enterprises, organizations and establishments control of the noise level at working places is checked no less than once a year. The State Standard 12.4.095-80 provides the basis for measuring, position of the control point in the booth, the frame and characteristics of measuring, mode of activity of engines and parts of harvesters, the amount of measurement samples (3 precise measurements), estimation of measurements and their correction, equipment, methods of measuring the results, temporary characteristics of measuring by the sound level meter in “slow” mode and frequency correction

abstract 1201606074 issue 120 pp. 1136 – 1145 30.06.2016 ru 443
The creation of better conditions for the cultivation of plants is carried out by means of mechanical impact on the soil working bodies of machines and tools, that is, the so-called tillage. Its importance in the conditions of intensive agriculture cannot be overemphasized. The use of each scientifically based crop rotation system of soil tillage is a necessary condition for further growth of crop yields and improve soil fertility. Tillage determines the processes of reproduction, fertility regulation soil modes, degradation processes and soil conservation. Important and how self-administration in the system of minimum tillage, and in addition to the deeper treatment of soil under traditional agricultural technologies is superficial and shallow tillage. Disc harrows are the most applied machine for the implementation of surface and shallow soil treatment, performing a loosening of topsoil, leveling the field surface, the destruction of soil crust, crumbling lumps of soil, weeding, seeding and fertilizer. This article describes the design features of domestic and foreign disc harrows. We have given their technical characteristics, and consider the operational and technological parameters

THE METHOD FOR CONTROLLING POTATO TUBERS HIDDEN DAMAGES

abstract 1201606077 issue 120 pp. 1166 – 1187 30.06.2016 ru 521
While mechanical harvesting of potatoes, about 20-40% of the tubers get damages. Dynamic loads, injuries of the tubers, causing internal damage – which is browning of the flesh of the tuber, which occurs in the process of its storage. At the same time, ways to express control of damage to potato tubers will allow both reducing damage during harvest, and promptly sending damaged potatoes for recycling before the results of mechanical stress for the tubers during harvesting. The definition of internal damage to the potatoes is possible because of the analysis of the different elasticity of the tissues of damaged and undamaged tubers. The value of overpressure of the device is chosen such way that during deformation of tubers there mainly has been compression of the damaged tissues of the tuber, with the least turgor. The degree of damage of samples of tubers is determined by the ratio of the volume of damaged tissues of tubers to the total volume of the sample. We have given the mechanical properties of tissues of tubers, fruits and root vegetables, their structure, dimensional characteristics, it can be assumed that the use of this method of determining internal damage possible for apples, carrots, beets and harvest of other crops. Use of damage control will enable timely identification of hidden damage and make it possible to eliminate their causes, which lead to increase loss products

HEAT AND AIR MODES OF AGRICULTURAL STRUCTURES

abstract 1201606081 issue 120 pp. 1223 – 1239 30.06.2016 ru 444
In this article, there are descriptions of ventilation systems of municipal and industrial buildings. We consider the scheme of natural ventilation and ventilation with mechanical drive. In agriculture production, processes accompanied by the releasing into the air of premises various harmful substances: gases and vapors, excess of heat and moisture. The source of the fumes and gases are various technological processes. People, animals and birds in the premises, release carbon dioxide and other gases. Sources of heat gain are the people, animals and birds, solar radiation, production equipment and so on. For optimization of parameters of the air environment, satisfying the hygienic requirements, need to install ventilation. The ventilation system – it is a set of devices for handling, transportation, supply and removal of air. The advantage of this article is the systematization of ventilation systems of production premises. We have identified the main flows of indoor air and placement of exhaust shafts. Greatest interest are the systems operating year-round or during the heat period and exhaust systems equipped with control devices in the form of a throttle valves or gate valves and a device for cleaning the air. We give sufficient attention to the thermal regime of premises, heat losses and heat gain through protecting designs. We indicated that a significant effect on the thermal state of premises might be provided by humidity level of fences, as well as potential of heat and moisture transfer

abstract 1201606096 issue 120 pp. 1425 – 1435 30.06.2016 ru 619
In the article, we perform an analysis of the means of shaping and formserialize in fur clothes taken in the production of domestic and foreign fur companies. The spatial form of fur garments is solved, in the main, constructive. The type, direction and amount of articulation were determined by the design of the product and the properties of the fur: the height of the hairline, the size of fur semi-finished product. The proposed positioning of the shaping of articulation in fur clothes has to be performed in the environment of 3D CAD. It is established that in modern models of the silhouette of a fur product may be formed not only by design divisions but also by a combination of the product of different types of fur. We have performed studies on the use of funds of formation in models of industrial collections fur coat 2015-16 presented on the trading spots of Moscow. We have conducted a monitoring of consumer preferences on the types of fur among women and determined the causes of loss of fur, clothing of spatial forms under adverse conditions of wearing. We have also proposed innovative means of formserialize in a fur garment of solid and perforated fur
