TO THE QUESTION OF THE SYSTEMATIC APPROACH TO QUALITY OF EDUCATIONAL PROCESS IN THE SYSTEM OF INDIRECT DOCUMENT FLOW

abstract 1181604077 issue 118 pp. 1213 – 1222 29.04.2016 ru 537
The article considers questions of workflow in the educational organization. It revealed the need to process everyday documents, which exchange does not have the character of strict accountability, but they are also crucial to the implementation of the work in the educational organization. The exchange of such documents is different from the traditional workflow, primarily, it is the speed of document creation and sharing them. We identified other requirements and limitations to the daily workflow of documents. The study proposed to divide document on direct and indirect. The article formulates basic differences between direct and indirect document. It also analyzes the advantages and disadvantages of traditional approaches based on file servers and cloud data storage. We list problems of implementation of the account running errands. We have offered the structure of the order in the approach. The study shows an approach to increase the quality of the educational process based on the implementation of the indirect workflow through the use of centralized WEB system for the exchange of files, documents, accounting running errands, organizing indirect document. The proposed approach takes responsibility for storage of files from the technical support department of educational organizations can work with the system with mobile and desktop devices

TO THE QUESTION OF FINDING THE OPTIMAL POWER LOSS ELECTRIC POWER NETWORKS BASED UPON SOLUTIONS OF TRANSPORT PROBLEMS BY THE POTENTIAL METHOD

abstract 1201606059 issue 120 pp. 870 – 887 30.06.2016 ru 444
The work is scientific and practical in nature, same as the discussed process of optimization of power losses in power networks based on the use of the transportation problem, namely the rules of the minimum element of the transport matrix, which is a valid solution. The mechanism of the improvement of the obtained feasible solutions to the tasks focuses on using the potential method, assigning each row and column of the matrix their corresponding potential. Using a basic variable and manipulating the elements of the transport matrix according to a specific algorithm, we implement the construction of a new support plan. Based on the plan and its acyclic, we build two cycles and determine the values of the estimates between direct and indirect transportation costs per unit of output. The resulting algorithm makes it easy to program all computational operations and quickly obtain the result of the optimization of power losses in the design of the electricity network, thereby reducing the economic and technological costs. As a result of joint use of transportation problems and potential method, we could find the optimal solution based on improved solutions more efficiently, and a scheme of optimal electric network. As consumers, in practice, there may be urban and agricultural, industrial enterprises, regional and district subordination, including industrial, agricultural and individual customers

THE ENGINEERING COMPLEXITY OF CONSTRUCTING THEORIES ON THE BASIS OF USE OF MEANS OF DISPLAY OF THE VARIOUS MODELS AND METHODS FOR DESIGNING DATA STRUCTURES

abstract 1582004003 issue 158 pp. 27 – 38 30.04.2020 ru 196
The article deals with the complexity of the construction of engineering theories in both scientific and practical direction based on the use of non-traditional approach to the problems of effective data monitoring, especially in the field of control systems of multicomponent representation of objects of system analysis. The study of the complexity of this issue involves a detailed consideration of the relationships of the elements of these objects on the basis of known methods, while the integration of heterogeneous knowledge obtained by such often independent methods becomes very time-consuming and poorly formalized. Currently, the processing of information and its subsequent presentation have changed significantly through the use of data mining (IAD), which includes not only the organization of the knowledge system in various missile defense, but also in the field of DSS. This, in turn, contributes to the effective formalization of fuzzy information and processing it in the form of fuzzy algorithms, which is an extension of the decision support system based on fuzzy logic – DSS NL. At the same time, it is necessary to emphasize the features of the proposed approach of the DSS NL, which is that it can be used in various missile defense systems, including for the effective analysis of statistical information of multicomponent representation of objects, which is used in determining statistical indicators to identify and assess existing and potential risks, adverse situations, as well as in the preparation of motivational grounds for managerial decision-making. For the purpose of more detailed establishment in real missile defense of the relations between objects it is offered to carry out by means of various degrees of dependence. For example, the types of graded connections are considered as fuzzy objective connections, and the use of expert systems and semantic links led to the construction of hypotheses analysis of situations and semantic relationship between them. A significant difference of the considered DSS NL is that each model is formed on the basis of a separate semantic network, and the system itself works with several models of Pro related or unrelated to each other. On the basis of the use of the concept of the relationship of proximity between concepts, belonging to the situation, its information part of the recommendations Are grouped according to the selected situation for their subsequent analysis and decision-making. On the basis of the principle of coordinating actions and construction of the function, taking into account the optimal time of the control action, the General algorithm of decision support for emergency production situations in the Pro low-rise construction, both in urban and rural areas
