Special Issue on Reliability Evaluation and Optimization of Supply Chain Resilience
Submission Date: 2024-08-31

Supply chain resilience has become increasingly crucial due to the unpredictable and volatile nature of the business environment, which is subject to sudden disruptions, such as natural disasters (Covid–19), political instability (Russo–Ukrainian War), and supply chain cyber-attacks. These events can severely affect global organizations’ performance, reputation, and financial position, resulting in revenue lost, opportunities missed, costs increased, and customer relationship damaged. Thus, there is a growing need for advanced methods and tools to help organizations evaluate or optimize the reliability for supply chain resilience to mitigate the negative impacts of such disruptions. The advanced methods could involve using mathematical models and algorithms to optimize network design, risk analysis, and decision-making under uncertainty. Additionally, advanced technology, such as machine learning and artificial intelligence, could be utilized to identify and predict disruptions and develop proactive mitigation strategies.

We invite submissions on topics related to supply chain resilience using Operations Research methodologies. We encourage submissions focusing on advanced methods for designing, planning, and optimizing supply chain networks that can withstand unexpected events and disruptions. Topics of interest include, but are not limited to:

⚫ Robust supply chain network design
⚫ Supply chain resilience measurement and assessment
⚫ Supply chain disruption forecasting and response
⚫ Supply chain reliability and agility

Special Issue on Ensemble AI-Driven Metaheuristic Optimization in OR: Newest Contributions in Theory, Methods, and Applications
Submission Date: 2024-12-31

Operations research (OR) is an analytical method which attempts to achieve more optimality of the real system under the given circumstances. It interacts in various scientific fields ranging from statistics, mathematicians, management science, logistics and supply chain management, vehicle routing problem, economics and business intelligence, systems and control, big data mining and IoT, to ecology, psychology, biology, and education. Employing OR professionals can help companies in obtaining the best achievable performance considering all possible options and outcomes, while taking their risks into account.

Majority of optimization problems in OR suffer from various complex issues such as large number of objectives (many objective problems), large number of constraints (highly constrained problems), large number of decision variables with different types (binary, integer, permutation, discrete, continuous), non-linearity, discontinuities, time-dependency and uncertainty of objectives/constraints, the need for model and/or solution robustness, etc. Therefore, traditional optimization techniques cannot be effective enough to solve these problems, and thus, heuristic and/or metaheuristic techniques must be applied. Over the past years, a great deal of effort has been invested in field of nature-inspired metaheuristic algorithms, which have been established as the most practical approaches to tackle the complexities that arise in real-world OR problems.

In recent years, various ensemble AI-driven metaheuristic algorithms have been developed to intelligently deal with the complex issues in OR problems, based on the application specifications. These algorithms are designed by hybridization of metaheuristics with other soft computing and artificial intelligence tools such as knowledge-based heuristics, fuzzy sets and systems, artificial neural networks, and machine/deep/reinforcement learning. Ensemble AI-driven metaheuristics can be helpful for a better understanding of optimization/learning processes to provide an additional value on the sustainability and productivity of firms and organizations. An appealing solution to improve exploration-exploitation balance during the search process is to combine population- and solution-based metaheuristics via sequential/parallel hybridizations. By exploiting problem-dependent heuristic information, ensemble heuristic-metaheuristic algorithms achieve a better complexity-efficiency trade-off than the both techniques when applied separately. Metaheuristic-empowered crisp/fuzzy heuristics are interesting solutions to solve Just-in-Time problems through a heuristic-based solution generator and a metaheuristic-based model tuning procedure. Moreover, various hybridizations of metaheuristics with machine/deep/reinforcement learning have been performed to a wide range of applications in OR.

This special issue is designed to highlight recent theoretical and methodological advances in ensemble AI-driven metaheuristic optimization algorithms and their applications in all aspects of OR. Topics of interest include, but are not limited to:

• Ensemble population- and solution-based metaheuristics
• Ensemble knowledge-based heuristic-metaheuristic algorithms
• Ensemble metaheuristic-fuzzy learning models
• Hybridization of metaheuristics and machine/deep learning
• Ensemble multi-objective optimization techniques
• Ensemble constraint handling techniques
• Metaheuristics with multiple local search operators
• Metaheuristic-enabled heuristics for Just-in-Time problems
• Metaheuristics for resource allocation problems
• Metaheuristics for logistics and supply chain management
• Metaheuristics for cleaner production and manufacturing
• Metaheuristics for sustainable and renewable energy systems
• Metaheuristics for urban and agricultural planning
• Metaheuristics for structural and mechanical engineering
• Metaheuristics for wireless communication systems
• Metaheuristics for IoT and smart cities
• Metaheuristics for big data mining and analytics
