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 work is done in a scientific and practical ways to
minimize power losses in the transmission of
electricity in the interregional distribution networks
from the sources to the consumer by the use of tasks,
ensuring the gradual improvement in the support
program, not only from the standpoint of the efficiency
of reduction of transported power loss, but also due to
a significant decrease the complexity of the
calculations. The resulting shortage of electricity
power associated with its transfer to the electricity
networks, has demanded the need to find possible
ways of reducing the value of electricity losses during
transportation, both by improving and by optimizing
distribution net-works schemes. Consolidation into a
single set of electrical equipment, called the power
cluster is connected to the sources of power and energy
consumption, make better use of new principles of
control technology and the transmission of electricity,
on the basis of an automated monitoring system,
ensuring the redistribution of energy flows and
optimize them. The process of electric power
transmission and reduction in electric power loss can be considered on the basis of linear programming
problems, and their modification in the form of a
transportation problem, and as a result, the transport
matrix. On this basis, manipulating the data table, we
can find acceptable solutions, well and then determine
the best of them. As examples, this work has carried
out the study on the basis of the three methods -
"northwest corner", the method of minimum unit cost
of electricity transport, as well as the method of the
potential. The use of these three methods yielded
acceptable solutions, to identify the most appropriate
for the number of steps carried out at the decision, to
reveal that the winner is the potential cost method
The article analyzes reasons that prevent the formation of stable and effective AIC associations of commodity businesses and processors of raw materials. Unbalanced process of the relationship between agricultural producers and processing plants have a negative impact on the economic situation of the organizations partners. Dictating low purchasing prices for raw materials by processing enterprises hinders profitability of agricultural producers. Purchase prices set by the processing enterprises of the dairy industry for milk, do not compensate for not only the production costs but also the losses from inflation. The rate of growth in energy prices is significantly higher than for livestock products, bringing its cost grew faster than sales prices. This leads to a dramatic reduction in milk production profitability. A paradoxical situation: on the one hand, dairies are facing an acute shortage of raw materials, on the other - exacerbated the problem of the sale of its milk producers at a reasonable price for them. The disparity between the purchasing prices for milk and retail prices for dairy products caused agricultural companies to seek alternative markets. Sharply increased sales of milk in the bottling of milk tankers, while many farms began to create their own recycling system
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
The integration of producers of raw materials and its processors into the agro-industrial complex is connected with the social division of labor, its specialization, the need for interaction between specialized branches and types of agro-industrial production. Agrarian enterprises are united in an effort to reduce the risk, the emergence of which depends on the climatic conditions, the spontaneity of the agricultural market, the dictates of processing enterprises, the need to increase the competitiveness of production. In the Russian practice, there were various organizational forms of integration, differing in the nature of economic ties between participants, the degree of independence of the enterprises entering the association, the combination of centralization and decentralization of management. Conventionally they are divided into associative - "soft" and corporate - "hard." The "soft" forms of association include as-association, union, non-profit partnership and strategic alliance. They can effectively function at the interregional level. A rigid type of integration ties is characteristic for combines, concerns, trusts, holdings. Agricultural consumer cooperatives are voluntary associations of legal entities and individuals residing or operating in a certain rural area on the basis of membership and pooling of money units in order to meet the needs of members in credit resources and other banks services. The conditions for the emergence of sustainable integrated associations in the agroindustrial complex require qualitative and quantitative analysis based on mathematical modeling
The article considers problems of the exchange of
information between teachers, students and
departments of educational institutions. It analyzes the
advantages and disadvantages of traditional
approaches: email, chat via phone, social networks.
The questions of placement of information to large
numbers of users were revealed. We also revealed the
need to address issues related to the publication of
major events, administrative announcements of
educational institutions, which are visible to all users,
and are assigned to a specific date. We suggested an
approach to the publication of the activities of the
individual system modules. The article shows a
mechanism of mass mailings, providing users the
ability to transmit information to two or more
recipients and to ensure the exchange of information
that is available only to send the recipient, as opposed
to the "wall". We found an approach to increase the
quality of the educational process, allowing rapid
exchange of information between staff, students and
departments of educational organization on the
example of the system "Social network educational
organization." In the approach, it has been proposed to take the ideology of social networking and project it on
the specifics and needs of educational institutions,
which will allow rapid exchange between staff,
students and divisions (departments) educational
organization. The study analyzed data on the age of
users of the system over a period of 30 days
This article is devoted to the situational approach to the crime aspect of goal-setting activities of a mediator in criminal proceedings. It discusses the mechanisms of reconciliation of the parties in criminal proceedings in the framework of a mediation procedure or application of mediation procedures of the parties of the criminal proceeding under applicable criminal procedure of law. Mediation is considered in the context of situational modeling and creating a system of activities of parties to the proceedings depending on mediablity or remediability of the situation. We analyze current criminal procedural legislation in the sphere of reconciliation on criminal cases of private and private-public prosecution. We have suggested considering a new direction for tactical activities of participants in the proceedings and tactical aspects in the framework of the procedural powers to reconcile the parties, and situational modeling in the framework of its application in the mediation process. In addition, there was given legal and scientific analysis of the possible tactical aspects of the use of mediation procedures in criminal proceedings. A new direction in the tactical aspect of the activities of all participants in criminal proceedings has been presented, which is a tactic of the application of mediation procedures. The process of potential reconciliation of the parties is considered in the context of the situational approach, and the activity of neurotransmitters, through case studies, depending on the possibility of reconciliation between the victim and the suspect. We have proposed a new scientific classification of situations, depending on the possibility or impossibility of the use of mediation procedures
The article describes the basic techniques for working
with Kontrol automated monitoring system. We suggest
the algorithm for creating and editing test databases,
software settings-governmental applications,
technologies used in the tests of text, graphics and
multimedia data
In this article, we discuss various issues related to the
formulas approximating the distribution function of
prime numbers pi(x). This question has occupied many
scholars, but the exact function is well approximated
function pi(x) over the number of positive integers not.
Based on certain hypotheses, we present a new
function s(x) is very well approximated pi(x). The
above article hypotheses are so important that their
numerical validation and refinement for the lengths of
the segments more in 1014 - one of the main areas
related to the problem of approximation of the function
pi(x) throughout the series of natural numbers. After
analyzing the behaviors and constructs many
functions, we are building the basis of the function
s(x), which is well approximates the function pi(x)
throughout the series of natural numbers. We also
present a table of values for x, less or equal 1022 for the
difference of s(x) - pi(x)
In this article, we present the fundamental theorem of
arithmetic and its role. We consider various rings for
its performance
