Special Issue on “Simulation, Modeling, and Decision-Making Processes in Manufacturing Systems and Industrial Engineering”

1. Introduction

The rapid evolution of emerging technologies, the globalization of industrial networks, and the increasing complexity of production ecosystems have fundamentally reshaped the paradigm of modern manufacturing and industrial engineering. The advent of Industry 5.0, characterized by cyber–physical systems, artificial intelligence, big data analytics, and the Internet of Things (IoT), has not only transformed production processes but also redefined the way decisions are made across all levels of manufacturing systems. These transformations have resulted in an unprecedented need for integrating analytical rigor with digital intelligence to ensure system adaptability, operational resilience, and sustainability. Under such a dynamic context, organizations are challenged to respond to volatile market demands, resource constraints, and environmental responsibilities, while maintaining competitiveness and innovation capacity [1,2].

In this evolving industrial landscape, simulation, modeling, and decision-making processes represent the cornerstone of scientific inquiry and managerial practice. Simulation enables researchers and engineers to construct virtual representations of real-world systems, allowing for the exploration of complex interactions among production, logistics, and human factors without the cost or risk associated with physical experimentation. Modeling, both analytical and data-driven, provides a mathematical abstraction to interpret, predict, and optimize system behavior, facilitating the quantification of performance indicators under various operational scenarios. Decision-making processes, built upon these analytical foundations, transform quantitative insights into actionable strategies—supporting evidence-based planning, real-time control, and multi-objective optimization in uncertain environments [3].

Beyond their individual contributions, the integration of simulation, modeling, and decision analytics forms the intellectual core of modern industrial research, driving advances in intelligent manufacturing, digital twins, and sustainable production systems. This triad enables researchers to bridge the gap between theoretical frameworks and industrial realities, linking predictive analytics with prescriptive decision-making to enhance efficiency, flexibility, and competitiveness. Furthermore, as industries progress toward the era of Industry 5.0—emphasizing human-centric design, resilience, and ecological balance—these methodologies will play an increasingly pivotal role in ensuring that manufacturing systems evolve not only technologically but also socially and environmentally [1].

In light of these developments, this Special Issue, entitled “Simulation, Modeling, and Decision-Making Processes in Manufacturing Systems and Industrial Engineering”, aims to provide a comprehensive academic platform for advancing the theoretical foundations, computational methodologies, and empirical applications that define the future of industrial systems research. The Special Issue gathers sixteen carefully selected studies that collectively address how simulation-based approaches, modeling frameworks, and decision-support systems can be seamlessly integrated to improve operational performance, sustainability, and strategic decision-making across diverse manufacturing and industrial contexts. These contributions reflect a global and interdisciplinary perspective, showcasing the synergistic relationship between engineering science, data analytics, and managerial decision-making [4].

From a theoretical standpoint, the papers published in this Special Issue contribute to a deeper understanding of how modeling and simulation interact within complex, multi-layered production systems. They extend classical paradigms by incorporating modern algorithmic techniques, such as machine learning, evolutionary optimization, and digital twin technologies, offering enhanced accuracy, scalability, and adaptability to real-world uncertainties. Methodologically, these studies explore hybrid approaches that combine deterministic and stochastic models, qualitative and quantitative analyses, and computational and behavioral dimensions of decision-making. This multi-method integration provides a richer, more holistic framework for understanding how industrial systems evolve and how managers can make informed decisions in dynamic, uncertain environments [5].

Practically, the contributions emphasize the translation of theoretical insights into applicable solutions that can improve the design, control, and optimization of manufacturing processes. Case studies span a wide range of sectors, including energy conversion, chemical processing, logistics, metal forming, and smart production, demonstrating how simulation and modeling can guide efficiency improvements, resource allocation, and sustainable innovation. For example, data-driven decision-support frameworks are shown to assist policymakers in shaping renewable energy strategies, while optimization-based models enhance the flexibility and reliability of production scheduling, maintenance planning, and quality control systems. Such works exemplify how industrial research can directly contribute to technological advancement and socio-economic sustainability.

Moreover, this Special Issue underscores the importance of integrating human factors, environmental concerns, and digital transformation into industrial decision-making processes. As manufacturing systems increasingly rely on autonomous and intelligent technologies, the role of human cognition, ethics, and collaborative design becomes more critical in ensuring that technological progress aligns with societal and ecological values. By bridging theory, computation, and application, the research featured in this collection not only advances academic understanding but also offers practical pathways toward the realization of resilient, intelligent, and sustainable industrial systems.

2. Three Interrelated Strategic Directions Were Detected by the Set of Contributions Gathered in This Special Issue

The collective insights derived from the papers in this Special Issue reveal a clear trajectory toward three interrelated strategic directions that are reshaping the future of industrial and manufacturing systems—efficiency, resilience, and sustainability. These pillars represent not only operational objectives but also the conceptual foundation for the next generation of industrial transformation. In terms of efficiency, the contributions demonstrate how advanced simulation and optimization techniques can significantly enhance production throughput, minimize waste, and reduce system variability. The integration of computational intelligence, including metaheuristic optimization and machine learning, enables dynamic process control and predictive analytics, achieving higher productivity with fewer resources. This transition toward “smart efficiency” underscores the value of real-time data integration, digital twins, and adaptive modeling in achieving leaner yet more agile operations.

Equally important is the pursuit of resilience, as modern industries face increasing uncertainty due to supply chain disruptions, market volatility, and environmental fluctuations. The studies presented herein demonstrate how modeling and decision-making frameworks can be employed to design systems that can absorb shocks and maintain functionality under stress. Multi-scenario simulation, probabilistic modeling, and robust optimization methods are emerging as vital tools for developing decision-support systems that can anticipate disturbances, evaluate alternative responses, and facilitate rapid recovery. In this way, these methodologies contribute to building organizations that are not only efficient in steady states but also adaptable and self-correcting in dynamic contexts.

Ultimately, the theme of sustainability pervades the Special Issue as a unifying vision. Several contributions integrate environmental, social, and economic perspectives into the design and assessment of industrial processes, promoting the transition from resource-intensive production models to circular and regenerative systems. Simulation-based environmental assessment, life-cycle modeling, and energy efficiency optimization illustrate how data-driven strategies can reconcile profitability with ecological responsibility. More broadly, these studies affirm that sustainable industrial development requires both technological innovation and strategic governance, ensuring that the evolution of manufacturing systems aligns with global sustainability goals and social well-being.

In synthesis, the cross-pollination of efficiency, resilience, and sustainability reflects a paradigm shift—from isolated process optimization to systemic intelligence and collaborative adaptation. This integrated vision positions simulation, modeling, and decision-making not merely as analytical tools but as enablers of holistic transformation. As industries continue to navigate the convergence of digitalization, globalization, and environmental transition, these three pillars will define the roadmap for advancing industrial excellence in the decades to come [6,7].
