This article investigates the theoretical and methodological foundations for implementing professional management models in the management of housing and communal services (HCS). The purpose of the study is to identify the conceptual boundaries of the transition from administrative-command management methods to a managerial approach and to substantiate the mechanisms for the practical implementation of this process. The article analyzes classical management theory (Fayol and Weber), the concept of professional management (Drucker), the theory of New Public Management (Hood, Osborne and Gaebler), and the Competing Values Framework developed by Quinn and Rohrbaugh, adapting these approaches to the housing and communal services sector. The research methodology is based on content analysis of regulatory and legal documents, historical-comparative analysis, and a systems approach. As a result, a theoretical management model consisting of four structural components (institutional, human resources, financial-economic, and digital-information) was developed, and a comparative characterization of traditional and professional management models was presented.
This study presents an efficient methodology for analysing the stress–strain state and load-bearing capacity of circular reinforced concrete columns under short- and long-term loading conditions. The proposed approach incorporates the nonlinear hereditary creep of concrete and the elastic–plastic behaviour of reinforcement, enabling accurate predictions without the need to classify elements as “short” or “long” or to separately account for eccentricity. A discrete analogue of the nonlinear hereditary creep integral equation was formulated and solved using a robust computational algorithm, which was validated through parametric studies. The findings indicate that time-dependent creep has a pronounced influence on structural performance, leading to a noticeable reduction in load-bearing capacity and highlighting the importance of considering these effects in design and analysis. The methodology ensures engineering-level accuracy, even for large time steps, and provides a unified framework for evaluating the deformation, stability, and parameter sensitivity of reinforced concrete structures.
Satellite operations rely on schedulers that must satisfy strict timing, dependency, and resource constraints. In current industrial practice, these scheduler configurations are often defined manually and remain largely static after deployment, making updates labor-intensive and limiting adaptation to changing operational conditions. This paper presents a model-driven decision-support framework organized around a Digital Twin instance for the supervised runtime reconfiguration of satellite scheduler configurations in safety-critical systems. The framework combines an Ecore-based scheduler metamodel, graphical modeling support, EVL-based validation, telemetry-driven monitoring, simulation-assisted optimization, and interpreter-based generation of deployable scheduler configurations. In this way, the same scheduler model is preserved throughout design-time specification, validation, optimization, supervision, and runtime configuration generation, while keeping final deployment under human control to ensure certification constraints are met. We demonstrate the approach on an anonymized industrial scheduling scenario derived from a commercial satellite case provided by Thales Alenia Space Italia. We evaluate the framework through two complementary activities: a focus group with six TAS-I experts, used as an expert resonance study to assess usefulness, understandability, and industrial plausibility, and a toolchain-level validation of the MDE pipeline, measuring model loading, constraint checking, configuration generation, and traceability. The results indicate that the framework may reduce manual scheduling effort, support traceable and consistent reconfiguration decisions, and help engineers reason about controlled adaptation of scheduler configurations to runtime evidence without altering the certified switching logic of the onboard platform.
