Modeling processes for preparing high-tech production using the virtual enterprise concept

The subject of this research involves the processes for preparing high-tech production. Preparation for production requires organizational, economic, and technological actions that guarantee the transition to serial production, considering the requirements of Industry 5.0 and the use of scientific and technological innovations. Preparation is carried out with the aim of the effective development of a new serial product, the introduction of modern robotic equipment and information technologies, including the Internet of Things, and the development of new forms of production organization. In conditions of economic instability and global competition, there is a need to reduce the stage of preparation for production and the life cycle of creating a high-tech product. A new complex product can contain various types of components: reusable components, combined components that contain elements of innovation, as well as new innovative components that ensure its competitiveness. For each component, it is necessary to plan the production preparation stage. Among modern approaches to organizing production, the creation of a virtual enterprise is relevant, within the framework of which enterprises are united to implement a specific project for manufacturing high-tech products. Tasks: to build a structure of a multi-level model of functional modules for preparing the production of high-tech products; develop a model for selecting partners of a virtual enterprise for fulfilling a portfolio of orders for the creation of high-tech products; develop a model for selecting suppliers of a virtual enterprise; develop an agent model for assessing the risk of creating a virtual enterprise; build a multi-level multi-agent model for creating an organizational structure of a virtual high-tech enterprise; build a scheme of applied information technology for preparing the production of high-tech products based on a virtual enterprise. The purpose of the publication is to study the stage of preparing the production of complex technical products to synthesize the architecture of a multi-level component model of the product by creating functional modules for preparing the production of high-tech products, as well as to develop a set of mathematical models that ensure the formation of a portfolio of orders and the selection of performers for its implementation; selection of suppliers for fulfilling orders by manufacturing enterprises; risk assessment of a virtual enterprise project. The mathematical models and methods used are: system analysis, optimization using integer programming, multi-criteria optimization, and expert evaluation. The following results were obtained: the study proposes a multi-level multi-agent model of the organizational structure of a virtual instrument-making enterprise and creates an applied information technology for preparing the production of high-tech products based on the models proposed in the publication. Conclusions. The main contribution and scientific novelty of the results obtained is in reducing costs, risks and the duration of preparation for the production of high-tech products by using the concept of a virtual enterprise for the preparation of production by implementing applied information technology, based on a developed set of mathematical models that ensure the formation of a portfolio of orders and the selection of performers for its implementation; selection of suppliers for the fulfillment of orders by manufacturing enterprises; risk assessment of the virtual enterprise project. Production preparation processes are carried out within the framework of building a virtual enterprise, the rational organization of which helps to reduce the duration of the life cycle of creating complex technical products.
