The article presents the way to identify the mobile agricultural equipment technical status control perio-dicity based on the comparison of its defect-free per-formance given probability with its calculated value in order to decrease significantly the efforts to estimate control periodicity and increase the results authenticity at the expense of mobile agricultural equipment prob-able characteristics calculation
Assessment of barley for the blotch incidence is traditionally carried out by visual determination of leaf damage with the help of the available expert – phytopathologist , and with the account scales which allows to characterize a variety for resistance or susceptibility to the studied disease in field conditions. This method has a number of disadvantages that are proposed to be overcome by developing a new tool of a phytopathologist. The measuring tool of a phytopathologist should provide high accuracy of the assessment of plants damage caused by the disease, and the measurement procedure should be quick and easy. The aim of this work is to develop a mobile tool of a phytopathologist for quantitative fast assessment of winter barley leaves damage caused by blotch in field conditions. To achieve this goal the following tasks should be fulfilled. Objective 1: introduce the idea and concept of problem solution; Objective 2: justify the choice of method and solution tool; Objective 3: apply the selected method and tool to solve problems, i.e. to perform the following steps: – cognitive structuring of the subject area; – formalization of the subject area; – synthesis and verification of models; – improvement of the quality of the model and choice of the most reliable model – solving diagnostics problems within the most reliable model (classification, recognition, identification), decision support and research of the simulated subject area by studying its model. Objective 4: describe the effectiveness of the proposed solution. Objective 5: examine the limitations and disadvantages of the proposed solutions of the problem and prospects of its development by overcoming those limitations and disadvantages. The article provides a detailed numerical example of the solution of tasks on real data processed with the ASC- analysis and "Eidos" system
The model of identification of process of a dust con-tent of the air is submitted. It is shown, that in a work-ing zone of foundry shops the significant amount of a dust is allocated. The most unsuccessful sites from a position of allocation of a dust are chambers and lattices. The experimental analysis shows, that in structure of a dust the weight maintenance of fractions with a diameter up to 20 microns reaches 43,8 % on weight. The dust is most dangerous to health of the working personnel and creates problems at clearing air. The model of structure of dusty air is received
On the basis of hydrodynamic analogy between turbulent transport of momentum, heat and mass transfer, and information in the conditions of modern electronic social networks, we consider a model of informational influence. The flow of information is represented as a stream of random events with simplest flow properties. In addition to the flow of information impact there were introduced the concepts of density, velocity and viscosity of the information flow. These parameters had been derived from the construction of dimensionless criteria characterizing the balance between inertia and viscosity of the information flow of information influence. This criterion serves as a numeric parameter determining the boundary
of the transition from low-intensity to high intensity of information influence the turbulent nature of the attack. We have also analyzed the ranges of changes and the meaning of the entered parameters from the point of the organized network information inserts. The existence of the information in time and procedural nature of the concept of information allow us to focus on the properties of information flow as inertia, dynamics and relaxation
In order to improve the security of information transfer we have offered one of the possible approaches to modeling process control computer networks with elements of intelligent decision support. We proceed from the graph model of network nodes which are network devices with software control agents, and arcs are logical channels of information exchange between the equipment computer systems. We built an addressless sensing technology which ensures the completeness of monitoring of all network equipment. To classify the computer networks state we provided a method for calculating the values of reliability. Development of signal mismatch triggers the control cycle as a result of which the adjustment of the state of network equipment. For existing tools we proposed adding network control expert system consists of a knowledge base, inference mechanism and means of description and fill in the knowledge base

The article considers a combination of the process-based and systematic approach in the management of OSH at the enterprise for the development of the OSH management system model. The OSH management system is created by the enterprise based on the model provision, the branch requirements and recommendations of the current standards. Features of the system are determined by the state of the external and internal environment of the enterprise (context). The context forms the basic requirements for the inputs of the system and determines its capabilities. An analysis of the context of the enterprise makes it possible to identify the system: describe its inputs and outputs, identify key stakeholders and consumers. Based on this analysis, a model of the OSH management system is suggested, which, in analogy with the modern model of the quality management system, allows us to identify the place of the OSH in the context of the organization, and also to clarify the interaction of the main groups of OSH
