Using a hybrid approach, the fuzzy Delphi method was first applied to refine a set of 19 factors extracted from the literature, validating 14 context-relevant elements based on expert consensus.

This study proposes the HybridNGS algorithm, a hybrid metaheuristic framework that integrates Nearest Neighbour (NN) for solution initialization, Genetic Algorithm (GA) for global search, and Simulated Annealing (SA) for local refinement, to address the Drone Routing Problem (DRP) in blood logistics. The model incorporates domain-specific constraints, including blood-type compatibility, energy-aware routing, and cold-chain preservation. Empirical evaluations using synthetic and real-world datasets comprising 20–100 hospitals reveal that HybridNGS consistently outperforms benchmark approaches such as GRASP and TSP-D, achieving up to 20 % cost savings, 15 % reduction in drone usage, and notable energy efficiency.

In the initial stage, a novel hybrid methodology integrates data envelopment analysis with artificial neural networks to identify optimal sites for agricultural waste collection facilities. This approach combines the performance assessment strengths of data envelopment analysis with the predictive capabilities of neural networks, enabling a data-informed site selection process. The second stage employs a mixed-integer linear programming model to optimize a closed-loop biofuel supply chain under uncertain conditions, targeting both cost reduction and minimized carbon emissions. A probabilistic scenario-based approach is utilized to address uncertainties, enhancing the model’s real-world applicability. Additionally, the Lagrangian relaxation technique is implemented to achieve precise solutions while preserving computational efficiency. For large-scale scenarios, the study leverages the non-dominated sorting genetic algorithm and multi-objective simulated annealing to generate near-optimal solutions.

However, the growth of EVs will lead to higher emissions if, in supply sector, the energy sources rely mainly on Non-Renewable Energy Sources (NRES), forcing to transition to Renewable Energy Sources (RES). While managing these transitions, it is also important to make sure that energy requirements can still be fulfilled which is driven by population dynamics. Thus, this complex interdependence indicates the importance of using systemic framework, although most previous studies focusing on one of transitions which can lead to policy misalignment and unintended trade-offs of sustainability performance.

We screened 136 studies and conducted bibliometric-performance and science-mapping analyses to identify research topics and trends. We synthesized diverse definitions and measurements of food accessibility, analyzed barriers affecting food accessibility, and established a three-tier taxonomy that maps specific barriers onto the three dimensions of food accessibility and five barrier classes. For each barrier class, we traced the causal chain and summarized the interventions reported in the literature. A brief comparison between sub-Saharan Africa and Western Europe shows that barriers and interventions vary by region. Based on these findings, we present a decision matrix that links barriers to actionable interventions and analytical tools.
