The model simultaneously incorporates renewable and non-renewable generation, energy storage dynamics, and probabilistic resilience metrics to ensure system reliability, economic efficiency, and emission compliance. It employs a set of coupled energy balance equations, emission constraints, curtailment control strategies, and stochastic demand–supply interactions modeled via Beta and normal distributions. Applied to a rural Indian energy scenario, the model demonstrates a significant improvement over conventional configurations. Specifically, the optimized case with both storage and emission constraints yields a cost reduction of approximately 26%, a curtailment decrease of over 60%, and improved system resilience and reliability levels approaching 98%. These improvements validate the model’s effectiveness in mitigating renewable intermittency, reducing operational inefficiencies, and supporting decarbonization targets.

This paper dwells on sustainable post-disaster humanitarian logistics (SPD-HL) with environmentally friendly and conventional vehicles. The problem aims to establish the routes, schedules, and charges of the heterogeneous fleet, which designs the distribution of multi-relief items to vulnerable people in emergency assembly points and temporary shelter areas spread out in a geographically dispersed area. The objective of the SPD-HL is to minimize the total time that covers total travel time, charging duration, and total earliness and lateness. To solve this new complicated problem variation, we developed a sophisticated metaheuristic that integrates an adaptive large neighborhood search (ALNS) with a problem-specific construction and local search procedures. We conducted extensive experimental analyses on new real-world data instances to examine the performance of the heuristic. According to computational results, the proposed method effectively yields high-quality solutions compared to CPLEX results in small-size instances and improves solution quality in large-size instances. Additionally, we conduct scenario analyses with an energy and social cost-based combined objective function and the probability of road closure cases due to consecutive disasters.

Against this background, this paper proposes a capacity sizing model for PECS tailored for ACTs, considering the AGV charging load modeling and lifecycle carbon emissions across multiple equipment types and lifecycle stages. Firstly, a multi-cycle AGV scheduling and charging model is developed incorporating internal-external vehicle segregation constraints for typical ACT layouts. Secondly, a lifecycle carbon emission model for PECS is constructed by clearly delineating the model boundary, which encompasses six lifecycle stages and incorporates four types of critical equipment. Thirdly, the carbon emission model is systematically integrated with economic objectives through interface variables, including equipment capacity and purchased electricity power. Therefore, a bi-objective optimal sizing model for PECSs is developed to maximize annual economic benefits while minimizing annual carbon emissions. The model is solved effectively using computational intelligence, specifically the Non-dominated Sorting Dung Beetle Optimizer, and validated through an experiment of a representative ACT.

Responding to patient demands is highly time-sensitive, leading EMS providers to use motorized vehicles. Motorized ambulances carry battery-dependent medical devices such as automated external defibrillators (AEDs). In this context, employing electric motorcycles not only ensures rapid transportation but also facilitates continuous charging of onboard medical devices throughout their routes. In addition, EMS demands are unpredictable, and new requests may dynamically occur while vehicles are en route to provide services. Therefore, dynamic response capability becomes critically important. To address these issues, this study proposes a MILP dynamic emergency routing problem model for electric motorcycle fleets considering battery swapping stations. The proposed model integrates routing decisions for both patients and battery swapping stations to effectively manage response time. The model is capable of dynamically receiving new patient demands and updating optimal routes in real-time upon information changes. Furthermore, the model includes soft time windows, and patient service time is treated as uncertain. Small-scale instances are solved using exact methods, while larger-scale problems are addressed through a Variable Neighborhood Search (VNS) algorithm. Numerical experiments demonstrate that the proposed algorithm can obtain solutions with 98% accuracy, operating much faster than exact solutions.

In this paper, we aim to challenge this hypothesis, as it is well known that there is always a non-zero percentage of defective products and raw material waste in real-life situations. Thus, we are trying to combine scheduling theory with the current and essential initiatives of Zero Waste Manufacturing (ZWM) and Zero Defect Manufacturing (ZDM), which aim to reduce waste and avoid failures and imperfections during production, respectively. Given this effort, we revisit and analyze several classic single-machine scheduling problems given ZWM. We assume the machine’s performance deteriorates and tends to increase waste or produce faulty products. Therefore, a Calibration and Preventive Maintenance Activity (CPMA) is essential to guarantee optimal performance in the planning horizon. To this end, we postulate that each product is penalized with a job-dependent waste cost. Consequently, we seek to minimize a scheduling measure subject to an upper bound on the permitted total waste cost or, alternatively, an upper bound on the defective products’ fixing (repairing) cost. First, we address the fixed time CPMA interval and then the floating time interval. The researched scheduling measures are the makespan and the total weighted completion time. As these problems are known to be ordinary NP-hard, even without the new constraints, we introduce pseudo-polynomial dynamic programming (DP) algorithms.

In response, this paper introduces a game theory-based scheduling algorithm that optimizes transportation tasks in Industry 5.0 settings, where human–robot collaboration is essential. By modeling AIVs as rational agents within a potential game framework, we reformulate JSSPT as a Multi-robot task allocation problem (MRTA), applying iterative best-response strategies to reach a Nash equilibrium that minimizes the overall makespan. Our approach uniquely integrates human movements into the scheduling process, enabling real-time adaptation to fluctuating production environments. Experimental results demonstrate that the proposed algorithm outperforms state-of-the-art methods, namely the VNS and entropy-based approaches, particularly in settings where human unpredictability significantly impacts performance. On average, the game-theory-based algorithm reduces the makespan by 7 s compared to the entropy-based algorithm and by 17 s compared to the VNS algorithm.

In response to this regulation, liner shipping companies have passed the cost of carbon emissions onto their customers. These companies typically levy an emissions surcharge per twenty-foot equivalent unit (TEU) container and calculate the surcharge based on individual trades, which typically encompass multiple origin–destination (od) pairs within a region. However, this surcharge structure fails to account for variations in distance between od pairs within the same trade. To address this limitation, we propose a carbon emissions allocation policy using an optimization method to allocate emissions per TEU for each od pair. This method incorporates both the shortest sailing distance and the actual traveling distance of the od pair, combining these into a harmonic distance. The harmonic factor represents the chosen carbon emissions allocation policy. Considering that carbon emission allocation should be tailored to specific shipping routes, this study constructs an augmented shipping network of multiple routes. Based on this network, we develop two od-link-based models: one with transshipment and the other without transshipment. Both models aim to maximize the profits of liner shipping companies. The models are validated through experiments conducted using real-world and synthetic shipping networks. The results show that the model with transshipment yields higher profits than the model without.
