The modern trends in the development of the logistics controlling through the prism of collaboration between wholesale companies and retail chains have been considered. The nature and structure of cargo transportation by the wholesale company to the retail chain have been analyzed. The key transportation processes have been identified and the reliance on transportation drivers - forwarders on their effectiveness has been determined. The study has resulted in the program-mathematical approach to the transportation controlling automation used by the wholesale company to deliver goods to the retail chain as well as the mathematical model of the system information flow. The practical recommendations for the mathematical software implementation using the AWS Forwarder software product as an example have been illustrated

Flow-based model for traffic management in communication network were proposed, which provides a consistent solution of the following network tasks: multipath routing; traffic policing; and dynamic allocation of network throughput among the users flows. Obtained solutions provide the required values of the key indicators of Quality of Service such as packet rate, average delay and packet loss probability.

The article reviews the main trends in the evolution of market research, approaches to special scientific and practical modeling and
worked actively relevant aspects of their problems.
The purpose of the article is to study and investigate species and modeling techniques used in marketing research.
The basis of marketing research modeling is to develop necessary measures to adapt the company (current or prospective) in the
market according to the needs of consumers to achieve the objectives to meet those needs with a focus on high technology and
ethical standards of considering that meet consumer needs must be more efficient than the competition. Scientific works of foreign
and domestic scientists who have made significant contributions to modeling market research were considered. As a result of these
studies considered quite successful use different techniques in marketing based on model designs, and calculation formulas used
in carrying out market research, design, distribution channels, pricing policies and the study of consumer behavior. We studied
a comprehensive model of marketing research, qualitative and quantitative models, mathematical model, which is a mathematical
description of the studied economic process or object, and verbal model by which marketers try to uncover the true feelings of
consumers, based on the conclusions made in choosing options for advertising illustrations for brochures, pictures on the package
of subjects for promotional videos. It was investigated that the object modeling in marketing, with potentially infinite variety of
relationships with the environment, though they are characterized by a set of “inputs” that creates or selects registration researcher.
The result depends on the arsenal of measurement tools and opportunities for their use, methods of collection and processing of
marketing information, the influence of the researcher on the “black box”. Need to use model “black box” arises when dealing with
the processes occurring in the environment or facility management of its operations, while the description of which we can’t use
information about the internal structure of the process.
Thus, the article outlines directions for further research, based on modeling of marketing research in the region.
We believe that our proposed methods and models provide more efficient conduct market research by aligning the respective functions
and nature of the necessary information to make appropriate management decisions.

The complex of mathematical models of investigated indicators has been developed to study the dynamics of budget indicators, forecast
their change and plan revenues and expenditures of state and local budgets appropriately. This is a linear dynamic model with
constant and variable coefficients, nonlinear nonstationary and stationary models of all studied indicators and also models of the
dynamics of the total amount of state and local budgets. Methods of establishing parameters of these models have been described.

The following paper presents queue management model that includes congestion avoidance mechanism and suitable for using on telecommunication network nodes. Within the proposed model on a network node consistently was solved Congestion Management and Congestion Avoidance tasks. At the same time general queue management task was reduced to solving of optimization problem. Within the congestion avoidance mechanism packets were dropped in order to prevent node buffer and link overload. Proposed mathematical model was investigated with analytical modeling methods.

A fault-tolerant routing model for unicast flows in MPLS-network is proposed. The flow-oriented model is represented by algebraic equations and inequalities characterizing the state of MPLS-network, i.e. load of its communication links. The proposed model includes the possibility to implement three basic backup schemes in accordance with the concept of Fast ReRoute: link, node and path protection. The model describes also three different types of condition of the links overload prevention for different variants of channel resource use. The above example demonstrates the advantages of using the proposed conditions of the links overload prevention in paper.

The results of development a mathematical model for capacity allocation downlink technology WiMAX. The novelty of the proposed model is possible preventive limit transmission rate allocated to the service flows of the user stations in the downlink by using the WiMAX technology linear or linear-quadratic objective function. It is shown that the use of a linear-quadratic objective function in comparison with the linear, can produce a more equitable management of requests based on the relative priorities. The analysis of known methods for dividing the time-frequency resource WiMAX technology showed that they all focus on the distribution between the subscriber stations all bandwidth downlink. The model proposed is directed to the allocation of each user station a guaranteed bit rate in the absence of overload downlink as well as the preventive rate limiting allocated user stations under overload conditions. Using the mathematical model is directed to distribution between subscriber stations of a time-frequency resource of the downlink, which in turn improves the conditions in the electromagnetic frequency range used. The influence of the priority request rate used in the model, the nature of the possible failures.
