The field of Flexible Manufacturing Systems (FMS) has seen in recent years a dynamic development trend and can now be considered an integral part of intelligent manufacturing systems and a basis for digital manufacturing. Developing the factory of the future in an increasingly competitive industrial environment involves the study and analysis of some FMS key elements and managerial, technical, and innovative efforts. Using a new approach, thus paper presents a material flow design methodology for flexible manufacturing systems in order to establish the optimal architecture of the analyzed system. The research offers a solution for modeling and optimizing material flows in advanced manufacturing systems. By using a dedicated analysis and simulation software, the structure of the system can be established and specific technical and economic parameters can be determined for each processing and transport capacity. Different processing scenarios will be evaluated through virtual modeling and simulations in order to increase the performance and efficiency of the system. Thus, an interactive tool useful in the design and management of flexible manufacturing lines will be developed for companies operating in the industrial sector. The application of this paper is mainly in the field of development of intelligent manufacturing systems, where the control system will make and use simulations in order to analyze current parameters and to predict the future.
Destination management organizations have a key role to play in the governance of tourism destinations, in managing destination networks and in ensuring good cooperation between stakeholders. Although, destination management organizations (DMOs) are atypical organizations, their operations are evaluated according to their organizational efficiency and effectiveness. This study aims to propose a framework to improve the management of the tourist destination through an innovative approach that interconnects strategic management and Lean techniques to increase efficiency and productivity in operational processes, organizational efficiency and effectiveness at the DMO level. The framework developed in this study interconnects the analysis of the internal environment through the Value Chain and the Lean Six Sigma methods identified to be suitable for application in the management of the tourist destination. Testing of the practical application of this framework was done for Association for the Promotion and Development of Tourism (APDT), which is the DMO that ensures the management of the tourist destination of Brasov, Romania. The research contributes to the optimization of the processes at the DMO’s level. The framework developed in this study can be implemented by practitioners to improve the management of the tourist destination. The paper also offers future research directions.
The integration of efficient production and management systems with the new Industry 4.0 concept represents a challenge for any company wishing to adapt its processes in order to increase performance, both at the operational and the organizational levels, through digitization and connectivity. This research proposes an analysis of Lean tools and Industry 4.0 technologies for compatibility in order to provide a framework model for development and integration in industrial applications. Through a systematic review of the literature, this paper contributes to the development of the current vision regarding the implementation and integration of the two “paradigms” of production. An analysis of the current key production strategies was performed through a new conceptual approach from the perspective of correlating the Lean management system, a system that has been stable in recent decades, with the innovative technologies of Industry 4.0. The applicative character of the research consisted of the optimization by simulation of a flexible production system in which the two concepts were integrated. The results showed that the implementation of Lean in the field of flexible manufacturing, correlated with the integration of Industry 4.0 techniques, such as digital twin and simulation, led to improved production processes by fast and flexible reconfiguration, with the two concepts being interdependent.
The research presented in this paper aligns with the advancement of Industry 4.0 by integrating intelligent machine tools and industrial robots within Flexible Manufacturing Systems (FMS). Primarily, a development approach for Digital Twin (DT) is presented, beginning from the design, sizing, and configuration stages of the system and extending through its implementation, commissioning, operation, and simulation-based optimization. The digitization of current industrial processes entails the development of applications based on modern technologies, utilizing state-of-the-art tools and software. The general objective was to create a digital replica of a process to propose optimization solutions through simulation and subsequently achieve virtual commissioning. The practical nature of the research is reflected in the design and implementation of a Digital Twin for a real physical system processing a family of cylindrical parts within an existing experimental FMS. A digital model of the system was created by defining each individual device and piece of equipment from the physical system, so the virtual model operates just like the real one. By implementing the Digital Twin, both time-based and event-based simulations were performed. Through the execution of multiple scenarios, it was possible to identify system errors and collisions, and propose optimization solutions by implementing complex, collaborative-robot equipment where multiple interactions occur simultaneously.
A topical issue globally is the development and implementation of renewable energy sources for sustainable development. To meet current requirements, the research in this paper is directed towards finding solutions to increase the performance and efficiency of wind power plants by implementing innovative solutions for hollow roller bearings developed through the use of sustainable growth programs in the field of green energy. Another solution that has the effect of increasing wind power performance consists of the implementation of a new large-size lubrication system for large-size bearings in wind energy units, which will increase their durability by developing maintenance capabilities. In this research, we will explore the possibility of introducing an innovative automated lubrication system in hollow roller bearings. The main results of the research, the innovative constructive solutions, will lead to important savings by lowering wind farm maintenance costs, increasing the durability of large bearings, and increasing the energy efficiency and yield of the whole system. The expected impact of implementing the solutions found will mainly be in the field of sustainable growth and environmental development.

In the current context of climate change in the world, it is increasingly necessary to implement strategies and ways of action to adapt industrial companies to sustainable production. The implementation of the Lean concept has a particular impact on creating added value, by reducing wastage, production waste and improving efficiency in order to obtain products/services of higher quality. Through a new approach, the authors propose the use of Lean techniques to develop sustainable manufacturing with an impact on the environment and their implementation in the production sectors. The main objective of the paper is to highlight the opportunities and challenges of Lean Manufacturing in the context of sustainable development. At the same time, the application of Green Manufacturing concept is the development of products/services/processes that save energy, natural resources, with beneficial effects on the environment. A starting point in the analysis will consist of the detailed study of the literature regarding the use of this two concepts, the limits that still occur in their implementation and the finding of a methodology for networking them. The results will demonstrate that integrating the two dimensions will lead to increased performance of the system and to the development of a sustainable company.
