РАЗРАБОТКА ЭКОНОМИЧЕСКИХ МОДЕЛЕЙ РАЗВИТИЯ ТЕХНИЧЕСКИХ СИСТЕМ ПО ЭТАПАМ ЖИЗНЕННОГО ЦИКЛА

Abstract

Introduction: when forecasting and simultaneously supporting the planned development of a set of large technical systems, it is required to develop an integrated mechanism for accounting for the state and costs of resources. The approaches known for these purposes are characterized by high complexity of implementation and fragmentation over the stages of the system cycle. Purpose: to develop a complex of interrelated economic models for the analysis and development of large technical systems. Results: on the basis of scientific directions of economic analysis, aspects of the development of economic models were considered and on their basis, modeling of complex composite technical systems by stages of their life cycle was carried out in the interests of the subsequent formation and adoption of managerial decisions both in the selection and implementation of such systems, and in support of their development. The set of economic models is combined into a generalized model of systems development in the interests of a comprehensive assessment of current and future costs, further forecasting and, based on the results of simulation and calculations, making effective decisions. Since a feature of the production of large technical systems is their serial nature of products, then the integrated model evaluates the costs both for individual systems and for the stages of their life cycle, and for the entire complex of systems as a whole. Modeling of various modes of financing the development of one system or their complex is predicted, the features for each stage of development are taken into account. The possibility of assessing the structural restructuring of the relationship of enterprises participating in the production process and changing the possible sequence of technological processes for the production of samples has been obtained. Practical relevance: the proposed model (s) for batch or piece production of products is recommended in specific science-intensive areas of mechanical engineering and is applicable, for example, in aviation, space, shipbuilding, mining, and other industries. Its application is especially important in the design, development and manufacture of products for government orders. Discussion: the presented solution is proposed to be formalized with a software package and to create an automated control system for the development, production, operation and disposal of large technical systems with the functions of a decision support system.
