SIMULATION OF LARGE-SCALE TRANSPORT NETWORKS USING METHODS OF MULTICRITERIA OPTIMIZATION AND TAKING INTO ACCOUNT STRUCTURAL DYNAMICS

abstract 1201606111 issue 120 pp. 1686 – 1705 30.06.2016 ru 842
In the article we present a spatial structure of largescale transport systems. The model of a transport network can be presented in the form of a graph, with a set of the nodes corresponding to elements of a network and a set of edges – to sections of roads the connecting these nodes. As the model of a card of roads, it is offered to use prefractal graphs which naturally reflect structure of communications when reviewing a transport network in different scales (the states, regions, areas). Prefractal graphs allow describing structural dynamics of the studied system in the discrete time. One of the most widespread scenarios of structural dynamics is the growth of structure. The statement of tasks of the organization of transport routes contains requirements criteria to finding of optimal solutions. Often these requirements and criteria are contradicting each other. It leads to appearance of a multicriteria problem definition. The multicriteria problem definition on a class of prefractal graphs is considered. The optimum algorithm of separation of the greatest maximum paths by the given criterion is constructed and estimates by remaining criteria are given. In operation computing complexity of the constructed algorithm of separation of the greatest maximum paths on a prefractal graph is calculated and advantage of operation of algorithm on last before algorithm of separation of the greatest maximum paths on normal graphs is justified. The constructed algorithm on prefractal graphs has polynomial complexity

PROSPECTS FOR DEPLOYMENT OF DECISION SUPPORT SYSTEM FOR THE ADEQUACY OF THE LEVEL OF LENDING TO SMALL AGRICULTURAL COMPANIES IN THE CLOUD ENVIRONMENT

abstract 1121508147 issue 112 pp. 2054 – 2066 30.10.2015 ru 877
This article describes the opportunities and prospects for the deployment of decision support system for the adequacy of the level of lending to small agricultural enterprises in the cloud environment. It reveals the shortcomings in the existing automation of small businesses, and therefore the necessity of developing a system to enable managers to quickly and correctly calculate the amount of required loan funds. The developed system has the ability to work remotely due to the lack of binding the user to a specific personal computer. It is implemented through the development of a DSS using cloud computing, in which computer resources are provided to the Internet users in the form of "online service". The article describes the architecture of popular models and cloud Webapplications; after that, it was concluded to use the Saas model with Multi-Tenant-mode support in the model development. The study provides an overview of the DSS functioning in the cloud. It has noted the main features of the software implementation of the system relating to the use of cloud technologies. We have calculated the cost of placing an application in the cloud via the online cost calculator called Microsoft Azure. We have also performed a preliminary assessment of the payback period of the project implementation of DSS. It is concluded, that this technology would be competitive at the software market

PERFORMANCE MODELS FOR SMALL PROCESSING COMPANIES OF AGRARIAN AND INDUSTRIAL COMPLEX (part 2)

abstract 1321708120 issue 132 pp. 1443 – 1464 31.10.2017 ru 367
The article proposes a solution to one of the problems of small business, which is creation of a part of the software of management of information system efficiency for small processing enterprises of AIC. The fact is, that currently, there are almost no information systems to support small business. All known information systems have approximately the same list of automated functions, covering the accounting phase, and sometimes phase of analysis. Practically, not affected by the evaluation function of the economic situation, prediction, planning and regulation. The proposed mathematical model has been developed on the basis of the creation of streaming schemes of one-product processing enterprises of agroindustrial complex and mathematical description of the proceeding financial and material flows

MARKET ANALYSIS AND MODELING OF BUSINESS PROCESSES OF PUBLIC CATERING ORGANIZATIONS OF THE KRASNODAR KRAJPOTREBSOJUZ

abstract 1021408024 issue 102 pp. 374 – 398 31.10.2014 ru 2607
In the article we present the analysis of the market of public catering of the Russian Federation, the Krasnodar region. The role of public catering organizations in the total volume of activity of Krasnodar Krajpotreb-sojuz and the terms of socio-economic development of the Krasnodar region has been shown? As well as the modeling of business processes of public catering organizations. We have also revealed shortcomings in the organization of business processes and suggested ways of further studying of identified deficiencies

MANAGEMENT OF PRODUCTION PROCESS IN AGRICULTURE ON THE BASIS OF ADDED VALUE CREATION CHAINS MODELLING AND ASSESSMENT

abstract 1562002015 issue 156 pp. 211 – 227 28.02.2020 ru 218
The article considers an approach to managing the production process in agriculture based on modeling and evaluation of added value chains. The work has proposed a scheme of links for the production chain of added value creation that contains source control and financing cash flow which comes first in the link of agricultural production, then produced products are supplied to the accumulator, and from there it sequentially passes through the links of the value chain of the cyclic processing facilities, from which finished products are marketed and the resulting revenue is directed to the source of funding and management. We have given mathematical descriptions of the movement of financial and material flows in the links of the developed value chain, and mathematical models for calculating the volume of material and financial flows are proposed. Financial flows were also investigated to compensate for the cost of converting material flows and their mathematical descriptions. The article obtains a mathematical model of the economic efficiency of the production process and proposes a mathematical model for calculating the minimum price for socially significant processing products
