A Conceptual model for cognitive management of manufacturing systems to increase competitiveness

Daschievici Luiza — 2026-05-20

The competitiveness of manufacturing systems is increasingly influenced by their ability to dynamically adapt to demand variations, economic constraints, and operational conditions. Classical manufacturing management approaches, based on static strategies or local optimizations, are often insufficient to meet these requirements in a dynamic industrial environment. In this context, the paper proposes a conceptual framework for cognitive management of manufacturing systems, based on a cyclic cognitive loop, which integrates continuous perception of the system state, performance analysis, decision mechanisms, and adaptive feedback. The cognitive loop is formulated by correlating the principles of cognitive engineering with machine learning techniques, with the explicit objective of maintaining and improving the competitiveness of the manufacturing system. The novelty of the paper consists in the structuring of a cognitive loop dedicated to competitive management, in which decisions to adapt manufacturing processes are guided by a quantifiable economic indicator, expressed by the unit cost of production. Unlike existing approaches oriented mainly towards digitalization and connectivity, the proposed framework emphasizes the cognitive autonomy of the manufacturing system and the direct link between cognitive mechanisms and economic performance.

The paper has a conceptual and methodological character, providing a theoretical basis for further developments regarding mathematical modeling, experimental validation, and industrial implementation of the proposed cognitive loop.

SUPPORT MECHANISMS FOR ENERGY EXPLOITATION OF RENEWABLE RESOURCES

Diaconescu Ioana — 2026-05-20

The paper identifies several support mechanisms for the energy valorization of renewable resources. In this sense, the starting point is the idea of simultaneous production of heat and electricity by using measures and mechanisms that involve the use of renewable resources. The mechanisms identified in this study can support the financing of these measures within a constantly evolving legislative and technological framework.

DETERMINING THE OPTIMAL REGIME OF THE CONVECTIVE OPEN- CIRCUIT DRYER. CASE STUDY

Ioana Diaconescu — 2026-05-20

The purpose of this paper is to determine the optimal operating regime of the opencircuit convective dryer, taking into account criteria such as energy efficiency, dry product quality, and operational costs. Optimization of the drying regime contributes both to reducing energy consumption and increasing the productivity and quality of the finished product.

MODERN 3D MEASUREMENT SYSTEMS

Daniela Ghelase — 2026-05-20

In many cases, planar measurement or the individual measurement of part dimensions using classic measuring instruments (caliper, micrometer, comparator, etc.) are no longer sufficient. This creates the need for spatial measurements, in which the part is analyzed and measured in a three-dimensional measurement system. High measurement accuracy and increased flexibility in measuring objects of various sizes and complex configurations, combined with the possibility of automatically determining the relationships between the various geometric elements of the parts to be measured, make coordinate measuring machines (CMM) powerful tools for controlling manufacturing processes

CONFORMITY ASSESSMENT MECHANISMS IN ROMANIA: ARCHITECTURE OF THE NATIONAL ACCREDITATION AND CERTIFICATION SYSTEM

Daniela Ghelase — 2026-05-20

This paper analyzes the architecture of the Romanian certification and accreditation system in the context of the European single market, highlighting the critical role of quality infrastructure for industrial competitiveness. The study explores the historical evolution of accreditation, from the first post-war technical standards to integrated digital systems, starting with 2025-2026. The Romanian accreditation system, although relatively young, has achieved remarkable digital and procedural integration, providing national companies with the "technical passport" necessary to operate on the most demanding European markets.
