Abstract This paper introduces a novel approach, the Modified Electric Eel Foraging Optimization (EELFO) algorithm, which integrates artificial neural networks (ANNs) with metaheuristic algorithms for solving multidisciplinary design problems efficiently. Inspired by foraging behavior of electric eels, algorithm incorporates four key phases: interactions, resting, hunting, and migrating. Mathematical formulations each phase are provided, enabling to explore exploit solution spaces effectively. The algorithm’s performance is evaluated on various real-world optimization problems, including weight engineering components, economic pressure handling vessels, cost welded beams. Comparative analyses demonstrate superiority MEELFO in achieving optimal solutions minimal deviations computational effort compared existing methods.

Abstract One of the most researched technologies among used for producing complex and diverse parts today is additive manufacturing. In manufacturing, production can be carried out using thermoplastic metal materials without requiring an additional process. Among manufacturing technologies, Fused Filament Fabrication (FFF) method widely worldwide due to its affordability broad application area. FFF a in which part formation achieved by depositing melted on each other. recent years, polymer such as polylactic acid (PLA), polyethylene terephthalate glycol (PETG), acrylonitrile butadiene styrene (ABS) have been frequently many industrial areas because they are lightweight, inexpensive, sustainable, provide sufficient strength engineering applications. This study conducted tensile, three-point bending, Charpy, compression tests PLA, PETG, ABS at angles 15°–75° 30°–60°, results were compared.

Abstract This study proposes a novel hybrid metaheuristic optimization algorithm named chaotic Runge Kutta (CRUN). In this study, 10 diverse maps are being incorporated with the base (RUN) to improve their performance. An imperative analysis was conducted check CRUN’s convergence proficiency, sustainability of critical constraints, and effectiveness. The proposed tested on six well-known design engineering tasks, namely: gear train design, coupling bolted rim, pressure vessel Belleville spring, vehicle brake-pedal optimization. results demonstrate that CRUN is superior compared state-of-the-art algorithms in literature. So, each case rest furnished best-optimized parameters least deviation. were enhanced RUN algorithm. However, these solution quality, prevent premature convergence, yield global optimized output. Accordingly, can also find aspects various spectrums managerial implications such as supply chain management, business models, fuzzy circuits, management models.

Abstract Nature-inspired optimization algorithms named meta-heuristics are found to be versatile in engineering design fields. Their adaptability is also used various areas of the Internet things, structural design, and thermal system design. With very rapid progress industrial modernization, waste heat recovery from power generating organization an imperative key point reduce emission support government norms. However, exchanger component applied processes. Out available designs, shell tube exchangers (SHTHEs) most commonly adopted for process. Hence, cost minimization major aspect while designing confirming constraints optimized variables. In this study, SHTHE performed by applying a novel metaheuristic algorithm which African vultures (AVOA). Adopting AVOA best-optimized value (least exchanger) parameters realized, all constraints. It was that able pursue best results among rest them can plate-fin tube-fin case studies.

Abstract Nature-inspired algorithms known as metaheuristics have been significantly adopted by large-scale organizations and the engineering research domain due their several advantages over classical optimization techniques. In present article, a novel hybrid metaheuristic algorithm (HAHA-SA) based on artificial hummingbird (AHA) simulated annealing problem is proposed to improve performance of AHA. To check HAHA-SA, it was applied solve three constrained design problems. For comparative analysis, results all considered cases are compared well-known optimizers. The statistical demonstrate dominance HAHA-SA in solving complex multi-constrained problems efficiently. Overall study shows robustness develops future opportunities optimize critical using HAHA-SA.
