    Various engineering designs are multi-objective as they contain more than one design goal to be optimized. These design goals theoretically inflict differing requirements on the technical performance of system design. To analyze the trade-offs amongst conflicting design’s multi-objectives and to explore respective design options, an optimization problem with multi objectives has been mathematically modeled in this paper. In the present work, multi-objective optimization of air conditioning conduits and nets design is formulated. The design factors also consider the cultural as well as quantifiable, subjective ergonomics constraints and control decision-making factors. The cultural constraints, such as geographical, historical, sociological, and organizational constraints that determine the efficiency of the design of these nets are also incorporated in the objective function. This is reproduced during the option of filtration and selection from the solutions population generated at the locals and other levels, in which influences of cultural factor and of the decisions making factors are reflected in the subjective preferences.

    En este artículo se propone una nueva técnica evolutiva que utiliza un algoritmo de optimización para problemas de anidamiento de formas irregulares en 2D, aplicado a procesos de corte de materiales como el corte de láminas irregulares y formas geométricas complejas. Esta técnica es adaptativa y mejora los resultados del proceso de corte y su optimización en comparación con otros métodos descritos en la literatura previa. La formalización y el modelado matemático se basan en la metodología de integración CAD/CAPP/CAM/CAP para piezas bidimensionales irregulares producidas mediante una optimización multinivel con restricciones de componente y la distribución binivel del proceso de corte en láminas. La decisión de selección y las soluciones finales utilizan un algoritmo adaptativo basado en la modificación dinámica de los objetivos durante la distribución de las piezas y utilizando la población obtenida para la elaboración de las trayectorias de corte del dispositivo de corte. Este procedimiento define un nuevo enfoque para la optimización binivel de configuraciones geométricas iterativas de piezas poligonales crecientes, utilizando el caso particular del método de Integración de Variables, denominado algoritmo de Exploración de una Función de Códigos Variables. Como resultado final, se deduce un nuevo esquema de integración de fabricación óptima que incluye la interacción hombre-máquina como componente.

    This study presents the design and validation of a Sidestick Captain/First Officer (CPT/FO) prototype with an oleo-pneumatic centering system as an enhancement for the FSTD A320 flight simulator, originally equipped with a conventional mechanical spring system. The objective was to improve the fidelity and response precision of the control system to provide a more realistic and efficient flight simulation experience. The methodology involved mechanical and structural design using SolidWorks, material selection (A36 Steel for the structure and 304 Stainless Steel for the control lever), and validation through static and numerical analyses to ensure structural integrity and system performance. The static analysis confirmed that the components operate within safe limits, and the integration of the oleo-pneumatic system provided a more stable and controlled damping response, closely replicating the behavior of the Airbus A320 Sidestick. Compared to traditional mechanical spring, electromechanical shock absorbers and hydraulic damper systems, the proposed design offers a smoother and more precise response while maintaining simplicity, low maintenance, and costefficiency. This innovation not only enhances the performance of the FSTD A320 simulator but also represents a scalable solution for other flight simulation models, contributing to more effective pilot training and opening opportunities for future improvements through advanced dynamic analysis.

    The aim of this research is to determine the average fluid velocity values and the average total pressure at the outlet of the ventilation system conduit for the drying, by air impulsion, of pineapples in packing plants, in order to ensure the required humidity level of the crown for its proper packaging. The CAD model of the air conduction was obtained in Solidworks and Computational Fluid Dynamics (CFD) techniques were applied to simulate the performance of the ventilation system. Air was indicated as the type of fluid, and an internal analysis of the pipe with roughness Rz = 3.2 μm. As a computational domain, the pipeline was established, from the connection to the fan to the outlet diffuser. As boundary conditions were established; a W and Z Manufacturing regenerative fan at the inlet of the flow pipe 618,439 m3/h, and at the outlet of the pipe the value of atmospheric pressure. As a result of the simulation, an average velocity value at the diffuser outlet of 127.294 m/s was obtained, higher than the required 96.06 m/s. An average total pressure value of 111718.73 Pa was obtained in the conduit suitable for the proposed purposes. For the conveyor belt, it is recommended to use, in each row of pineapples, the simulated fan with a simple diffuser with a rectangular section of 1 x 20 cm, or a regenerative fan with a flow of 1248.77 m3/h and a diffuser with two-outlet bifurcation.</jats:p>

    <jats:p>The goal of this paper is to obtain an automated system for the control of the quality of the combustion gases of a boiler. The concentration of oxygen present in the combustion gases is detected by means of a lambda sensor, and a proportional PID controller automatically regulates, through an actuator, the air inlet to the boiler, thus ensuring the emission of CO2 and other polluting gases into the atmosphere within the parameters established by the current environmental regulations. The control system has an HMI display and a modular PLC. The results achieved also ensure the reduction of fuel consumption of the boiler.</jats:p>

    In the last decade, AISI 316L austenitic stainless steel has been considered one of the most useful materials for high-demand equipment in the industry due to its mechanical properties. This work shows the multi-criteria analysis of the dry and MQL turning process of AISI 316L steel using the non-dominated sorting genetic algorithms class II and III (NSAG-II and NSAG-III). The wear of the cutting tool (VB), the energy consumption (E), and the machining time (t) are used as study variables, with the aim of minimizing the wear of the cutting tool based on the optimal selection of machining parameters. When comparing the results obtained from both methods, we found that NSAG-III was the best alternative for selecting parameters in the turning operation, with fewer tool wear, more efficient use of energy consumption, and more variants of material removal rate.
