DEVELOPMENT OF A MODEL FOR IDENTIFYING AND FORECASTING THE HuMAN CONDITION AS THE MAIN INDICATOR OF SAFETY MONITORING SYSTEM IN THE ENTERPRISE page 10-17
The article is focused on the development of new and improve ment of existing mathematical models for identifying the human condition as the main safety indicators in the framework of an indus trial enterprise. Existing models and methods for solving problems on safety are aimed at the formation and maintenance of accounting and reference documentation, and inadequate for solve the problem of quantitative monitoring, analysis, prediction and control of si tuations.
Safety protection in the workplace and the health preservation of employees is possible only at the account, control, analysis of their conditions and forecast of the changes in this condition during the la bor process. Solution of these problems is possible only with the help of the information monitoring system covering the first level of the hierarchical management structure -the workplace, and implemen ting accounting, supervisory and regulatory system tasks, the results of which can be used for planning or regulation of safety on the object of management or its individual processes.
The proposed consideration of an employee condition is de scribed by a set of parameters characterizing the activity of the organism. The use of this indicator in determining the employee condition and a change of condition under the joint influence of the complex of harmful factors will allow to realize the functional tasks of accounting, control and analysis of employee condition in the moni toring system that allows management decisions to ensure safety.
Use of the proposed models for condition determination under the joint impact of harmful factors on the human body make it pos sible according to set of quantitative parameters of body functioning: -Determine the human conditions and predict changes in it.
-Take into account the initial condition of the employee.
-Take into account the change of this condition under the influence of the complex of harmful factors.
-Take into account the possible effect of the combined effects of this complex.
Keywords: labor safety, complex of harmful factors, parameters of employee condition, monitoring system. Management of repair and restore of the building objects is the object of this research. The main disadvantage of the object is a pro cess management according to planned in advance, before the start, project network, which doesn't take into account in the process of repairing and restoring the numerous effects of internal and external environments in the process of repair and restore that slowing and expensing the process and deteriorating the quality of its results.
At the same time it is shown that repair and restore of the buil ding structures are almost always is their reengineering, has a unique and performed in conditions of significant restrictions on resources in all functional areas that makes this kind of activity as the project by definition and its management -project management.
A reengineering management method for the building is deve loped. It is based on the project approach in resourcelimited condi tions. The method allowed to evaluate and predict the reengineering in terms of not only purely technological constraints, but also taking into account the turbulent environmental impact in all functional areas.
A «REBUS» system for optimization and support of design deci sions, as well as reducing the cost and timing of project work, was developed on the basis of the proposed method. It was implemented in Odessa «Geomoras» LTD (Ukraine) with the positive technical and economic effect. This effect was achieved by replacing an open loop reengineering management (planned -realized) to the closedloop (planned -realized under constant monitoring and interven tion), which allowed to quickly predict, prevent and eliminate the consequences of all possible risks that accompany a real unique reengineering.
Keywords: reengineering in the building, project management, resource limits, functional areas. An elastic interaction of angular motion of the helicopter fuse lage with the operating table panel is analyzed as the object of re search. An urgent surgery for victim immediately after its delivery to the helicopter is made possible through threeaxis stabilization of the operating table panel of mobile hospital in the vehicle, in particular, in the form of modular construction in a helicopter.
Functional content is based on the use of Petrov twochannel principle for formation of operating table structure that invariant to external disturbances.
A mathematical model of mobile hospital is developed and con struction accuracy of horizontal panel in a stochastic structure of the angular motion of the helicopter is evaluated. The values of mathemati cal expectation of the platform drift relative to the stabilization axes are defined. It is recommended to use differential two inertial sensors for each stabilization channel. It is proposed to carry out a further increase in the stabilization accuracy by the introduction of negative feedback on the sum of the sensor signals that are common for two gyroscopes The research results can be used by medical services in conjunc tion with transport organizations responsible for the maintenance of mobile hospitals. Advantages of twochannel scheme for inertial sensors are in suppressing of the influence of instantaneous values of external disturbances as a stochastic angular motion of the vehicle.

DEVELOPING OF ADAPTIVE MODEL PREDICTIVE CONTROL SYSTEM FOR HEAT TREATMENT OF IRON-ORE PELLETS WITH uSING RECuRSIVE LEAST SquARE ALGORITHM FOR ONLINE PARAMETER ESTIMATION page 30-34
The article discusses the problems of development of the sys tem of adaptive predictive control of pellets heat treatment with online estimation of parameters of the process model. Due to non stationarity in time of the process parameters caused by fluctua tions of particle size distribution and fractional void of the layer, changes in the process equipment characteristics and the presence of noise in measurement channels, the existing automation systems of pellets heat treatment do not always allow to solve the problem of stabilization temperature profile in the pellets layer, as well as reduce the specific consumption of energy. To overcome these dis advantages the recursive least squares algorithm is proposed to use for estimating the parameters of process model which subsequently is the base for calculating the manipulated variable (the gas flow to the burner of the leading side of the indurating machine) with using the methods of Model Predictive Control theory that provides maintenance of a preset temperature regime of pellets indurating under conditions of uncontrolled disturbances. In ac cordance with the described approach it is suggested the variant of the structure of the system of adaptive predictive control of the temperature regime of pellets indurating in the separate gasair chamber of indurating machine, and the simulation of this system was performed in Simulink package with the use of real data about the dependence of temperature in the heart of firing zone from gas consumption on the burner of leading side, which were obtained in a mode of passive experiment at the indurating machine OK324 of JSC «Central GOK (ME)». The resulting system has demon strated the high quality of the online estimation of parameters and sufficient convergence rate for conditions of pellets heat treatment. The obtained results allow us to recommend the developed method of formation of adaptive predictive control for automation of pel lets heat treatment.

THE DEVELOPMENT OF METHODS TO IMPROVE PERFORMANCE OF THE LOGISTICS CHAIN WITHIN THE TRANSPORT AND LOGISTICS CLuSTER page 48-52
The problems are irreversibly occurred during the transporta tion process. It is lead to loss of quantity, quality of the cargo and increase of the transportation time, so that the cargo «hangs» in the turnaround. The main disadvantage is the quality performance of the transport services -quantitative characteristic of one or more con sumer properties of services that make up its quality. Transportation quality is measured at the aggregate of characteristics that determine their suitability to meet the needs of consignors and consignees in the corresponding transportations. This disadvantage is associated with low functional performance of transport, such as maneuverability, low speed, ease of reception and delivery of the cargo, closure of the service system, adaptability to customer requirements.
The research is focused on the development of measures to improve performance during the transportation process. A process chain analysis on the basis of risk analysis is applied in order to develop these activities. At the same time, a reliable criterion based on the functional parameters of the object is proposed to reduce the risks of action on the logistics chain. Its essence lies in the fact that the criterion shows the degree of reliability of the transport company, thus creating potential and information to determine transportation priorities (quantity/quality).
This method can be used to create a database for characteristics of the transport company.

The data transmission process in cyberphysical system (CFS) with wireless communication channels between cyberphysical ob jects (CFO) is studied in the article. In the presence of obstacles (me chanical and electromagnetic),zero direct visibility or exceeding the allowable distance between CFO (WiFi communication modules of unmanned vehicles -UMV -and/or mobile devices) that need to share data, it is necessary to take measures to restore broken commu nication line or to stabilization of the data transmission rate.
The method for regularly radio situation overriding in CFS coverage area is proposed. The stability of wireless communication is achieved by changing energy and frequency characteristics of the communication line between CFO, as well as through the use of intermediate CFO as the signal transmitters. An algorithm for per forming the specified settings depending on the model of used cyber physical components, the distance between CFO and the delay of time interval is described. The fullscale experiment in the field using real hardware and software and with the presence of electromagnetic interference has been recreated to verify the algorithm. It is shown that for certain set of initial parameters, reducing a WiFi module maximum power by 50 % improves the quality of communication in almost 8 times.
Assessment of changes in the data transmission rate depen ding on the number of retransmissions is conducted. The stability performances of data transmission rate up to 90 %are improved by transition of communication line to another frequency range with less interference and introduction of signal retransmission function using intermediate CFO.
The direction of future research is dependent on trends in the market of construction materials for UMV and computer compo nents with builtin WiFi communication modules.
Keywords: moving objects, stability of wireless communications, cyberphysical objects, computer components, WiFi transmitting modules.

IDENTIFICATION OF THE CONTExT ELEMENTS OF KNOWLEDGE-INTENSIVE BuSINESS PROCESSES BASED ON THE LOG ANALYSIS page 65-71
Knowledgeintensive business processes are studied. They are characterized by the direct influence of performer's knowledge on the sequence of process execution. Performers use formalized personal knowledge for correcting of the process. Therefore, to increase the control effectiveness of knowledgeintensive business processes it is necessary to formalize the performer's knowledge and include them in the process model. Relationship between the context elements and process actions is shown based on the analysis of business processes logs. Context elements are displayed in the log using the event at tribute values, and that leads to the ability to highlight the links between the context and process. The method for extraction of con text elements of knowledgeintensive business processes is proposed based on the log analysis. The method allows to identify context ele ments, change the values of which are associated with process activi ties. The method creates the conditions for increasing the efficiency of process control by inclusion of dependencies, which identified by analyzing the context elements, in the process model.
Keywords: knowledgeintensive business process, intelligent pro cess analysis, process control.
