MINIMIZATION OF RESOURCE COSTS IN THE DISTRIBUTION OF PRODUCTION TASKS OF A COMPANY TAKING INTO ACCOUNT ITS STRUCTURE

abstract 1541910030 issue 154 pp. 317 – 326 30.12.2019 ru 9
The problem of the optimal distribution of production tasks is one of the important problems of effective planning of processes associated with production at the enterprise. However, the classical approach to solving this problem becomes of little use when the individual stages of the production process are performed sequentially and in the case when it is necessary to take into account the structural features of the technological processes of the enterprise. Purpose of work: to develop a methodology for minimizing costs in the distribution of production tasks, taking into account the structural features of the technological processes of the enterprise. We built a multicriteria discrete optimization model for the distribution of production tasks according to the structure of production elements. One of the methods based on the proposed model is proposed, which allows to identify groups consisting of four elements in the production structure of the enterprise. The model is built using a network design which are pre-fractal graphs. The use of pre-fractal graphs allows you to naturally represent the structure of production and technological links of the elements of the production system of large enterprises. The results of the work is the developed effective methodology for solving the problem of the network distribution of production tasks, taking into account the structural features of technological processes at the enterprise, the economic effect of which is to minimize resource costs. Based on the constructed model, we can develop automated means of monitoring and managing the production processes of a company

COGNITIVE ANALYSIS AND MODELING OF THE STAGES OF THE LIFE CYCLE OF ORGANIZATIONS IN THE PROCESS OF DEVELOPING ORGANIZATIONAL STRUCTURES

abstract 1341710105 issue 134 pp. 1322 – 1339 29.12.2017 ru 71
The article substantiates the necessity to use factors that trigger development mechanisms and describe risks at various stages of the organization's life cycle in the process of developing organizational structures for such large social and economic systems as corporate integrated structures characterized by the presence of diverse organizations in their structure. A comparative analysis of approaches to the description of the life cycle was conducted, as a result of which it was determined that L. Greiner's model is incomplete (it describes only the stages of development), and I. Adizes' model contains a blurred system of factors. To solve the problems, the model of I. Adizes was chosen as the basic approach and the characteristics of the stages of the life cycle of the organizations are selected. To formalize the factors that trigger the development mechanisms and describe the risks at various stages of the life cycle of organizations, a cognitive analysis and modeling apparatus was chosen and a corresponding methodology was developed. The implementation of the methodology is represented by the example of the first stage of the organization's life cycle ("Courtship"), which resulted in the compilation of a list of factors, their mutual influence on each other, the type of communication, and the cognitive model. Analysis of the cognitive model allowed us to determine the key factor that has the greatest impact on the transition to the next stage of development

THE DEVELOPMENT OF THE TWO-LEVEL TECHNIQUE FOR ASSESSMENT OF THE MISSED BENEFIT DURING THE LANDING AND CULTIVATION OF PERENNIAL PLANTS

abstract 1321708128 issue 132 pp. 1478 – 1491 31.10.2017 ru 80
The article describes the process of developing the two-level technique for assessment of the missed benefit during the landing and cultivation of perennial plantings. The technique is developed for the enterprises where the cycle of production of raw materials breaks into several periods until the first harvest. The choice problem of the most suitable grades for the landing is relevant for such enterprises. The first level of the two-level technique assumes assessment of qualitative and quantitative characteristics of grades with use of such tools as the theory of fuzzy sets and the decisions tree. The results of the first level are entrance data for the second level where there is final assessment of a grade and determination of the missed benefit rather potentially possible at the choice of the recommended grade. In the article also designated the importance of the raw materials stage for the technological chain. It is shown that, being consecutive structure, the technological chain strongly depends on the first stage – a stage of raw materials production. Minimization of the risk situations at the first stage promotes strengthening of the general risk tolerance of a technological chain

THE TECHNIQUE AND THE MODEL OF THE RISKS ASSESSMENT OF MACRO ENVIRONMENT OF THE AGROINDUSTRIAL INTEGRATED PRODUCTION SYSTEM ON THE BASIS OF THE INTEGRATED INDICATOR

abstract 1231609099 issue 123 pp. 1454 – 1471 30.11.2016 ru 237
The analysis and assessment of risk at the macrolevel in this context is understood as assessment of extent of influence of the external environment (macro environment) on activity of the integrated production system. In the article the model and the technique of calculation of an integrated indicator of risk of an adverse effect of the external environment of the agro-industrial integrated production system is offered. All stages of creation of the model which include representation of basic risk factors of macrolevel in the form of linguistic variables are described, each of basic risk factors is a compound linguistic variable. For obtaining total value of a basic factor the matrix scheme of aggregation of compound factors to basic level is used. The equation of model of an integrated indicator of risk of an adverse effect of the external environment on the integrated production system is presented. The principle of recognition and interpretation of result on the basis of standard fuzzy 01-classificators is shown. Also in this article the interrelation of an integrated indicator with the choice of the strategy of development for business system by definition of a condition of the external environment is shown, and depending on it the strategic scenario of development of business system is offered

THE DEVELOPMENT OF AN INTERVAL MODEL OF THE EFFICIENCY OF AN AGROINDUSTRIAL INTEGRATED PRODUCTION SYSTEM ON THE BASIS OF THE INTEGRATED INDICATOR OF RISK OF THE INTERNAL ENVIRONMENT

abstract 1231609100 issue 123 pp. 1472 – 1487 30.11.2016 ru 239
In this article the model and a calculation procedure of an integrated indicator of risk of the internal environment of the integrated production system are described. Then the steps of creation of triangular fuzzy number for expected value of profit are given. At creation of this fuzzy number the concept of an indicator of risk of the internal environment of the integrated production system was used. Further on the basis of the developed model of internal risk the interval model of efficiency of the integrated production system is developed and described. In this article the structure of a production chain of the integrated production system of agroindustrial complex was considered. In technologically complete production chain, as a rule, allocate three stages – raw materials production, storage and conversion, sale of finished goods. Each subsequent stage depends from previous stage, and at each stage various situations of risk are shown. Also the process of risk identification of the internal environment of the integrated production system was considered in this article. Process decomposition is executed, the description of subprocesses is given. For a risk assessment of the internal environment it is necessary to know quantity of production chains, and also to calculate value of risk for each production chain on the enclosed algorithm. Also in the article the principle of recognition and interpretation of results of calculation of an integrated indicator of risk of the internal environment of the agro-industrial integrated production system on the basis of Harrington's scale and standard indistinct 01 classificators is shown

THE MODEL OF EFFICIENCY OF THE TECHNOLOGICAL CHAIN IN THE AGROINDUSTRIAL INTEGRATED PRODUCTION SYSTEM CONSIDERING POSSIBLE RISKS

abstract 1131509074 issue 113 pp. 1014 – 1032 30.11.2015 ru 315
In this article, the general structure of technologically complete production chain of the integrated production system of agroindustrial complex was considered. Three different variants of creation of the production chains are described. The main distinctions in activity of chains consist in a source of raw materials. Any technologically full vertical chain includes three stages – production of raw materials, storage and processing, realization. Each of stages is characterized by different situations of the risk. Stages of process of functioning of a production chain were considered in this article. Also, the qualitative analysis of risk for all stages is made and the results of this analysis are considered. Results of this analysis became a basis for improvement of stream model for determination of efficiency of the technological chain taking into account a risk component. In the article, the algorithm of an assessment of efficiency of the technological chain of the integrated production system taking into account a risk component at the stage of creation of a material stream is also described

INTEGRATED PRODUCTION SYSTEMS OF AGRO-INDUSTRIAL COMPLEX

abstract 1131509073 issue 113 pp. 1002 – 1013 30.11.2015 ru 668
This article is devoted to consideration of questions of agro-industrial integration. Agro-industrial complex is a difficult dynamic system, including different branches of a national economy. In this work, the scheme of agro-enterprise functioning is submitted. The scheme was constructed with use of so-called “black box” model. The agro-enterprise significantly differs from the enterprises of other branches by a number of signs of. It is connected with the fact that agricultural production is characterized by high degree of uncertainty. Tasks of the uncertainty analysis, and, as a result, different risks of the agroenterprises are actual. Development of the effective mechanism of risk management is also an important task. In this article, the features of risk classification in agroindustrial complex, including the specific risks, are considered. The agroenterprises actively use integration mechanisms for decrease of possible consequences of a risk event. There are vertical and horizontal integration. Structures of the integrated agro-industrial production systems, which construct taking into account vertical and horizontal communications, are considered in this article. The most effective is vertically matrix integration in which the diversification mechanism of business is considered. The feasibility of the risk assessment with due regard for integration communications is proved
