Annotation: The article discusses the concept of continuous product design based on PLM (Product Lifecycle Management) systems with electronic models in the form of digital twins. The analysis of existing PLM systems has shown that these systems are currently applied software that can interact with various products in order to perform their functions. The main functions of PLM systems at the stages of the product life cycle (PLC) are considered. Based on the interaction of PLM systems as applied software with the main software products, a functional diagram of the interaction of PLM systems and a diagram of the attributes and services of PDM (Product Data Management) systems are constructed. The prospects of taking into account the ability of artificial intelligence to analyze large amounts of data, recognize patterns and extract useful information to improve traditional management processes of housing and communal services. The transition to model-oriented system engineering (MBSE – Model-based Sys) is justified. The central idea is to transfer the main role in the product design process from documents to electronic models. The concept of a digital twin, based on the MBSE methodology, is proposed to ensure the continuity of the design process. The sequence of automated design using digital twins is considered. Based on the Wymore model, an algorithm for automated design is constructed. A diagram of objects, which are data structures that provide services for their processing, is used to describe the metamodel. The factors of product design continuity have been identified to ensure their sustainable operation with minimal upgrades, the main of which are the calculation of an evaluation function that determines the deviation of the complex's operation parameters from the specified values, which determines the need for upgrades, as well as the availability of a mechanism for developing a new complex implementation architecture.
