The exponential growth of Internet of Things(IoT)devices has created unprecedented challenges in data processing and resource management for time-critical applications.Traditional cloud computing paradigms cannot meet the stringent latency requirements of modern IoT systems,while pure edge computing faces resource constraints that limit processing capabilities.This paper addresses these challenges by proposing a novel Deep Reinforcement Learning(DRL)-enhanced priority-based scheduling framework for hybrid edge-cloud computing environments.Our approach integrates adaptive priority assignment with a two-level concurrency control protocol that ensures both optimal performance and data consistency.The framework introduces three key innovations:(1)a DRL-based dynamic priority assignmentmechanism that learns fromsystem behavior,(2)a hybrid concurrency control protocol combining local edge validation with global cloud coordination,and(3)an integrated mathematical model that formalizes sensor-driven transactions across edge-cloud architectures.Extensive simulations across diverse workload scenarios demonstrate significant quantitative improvements:40%latency reduction,25%throughput increase,85%resource utilization(compared to 60%for heuristicmethods),40%reduction in energy consumption(300 vs.500 J per task),and 50%improvement in scalability factor(1.8 vs.1.2 for EDF)compared to state-of-the-art heuristic and meta-heuristic approaches.These results establish the framework as a robust solution for large-scale IoT and autonomous applications requiring real-time processing with consistency guarantees. 展开更多

An aircraft carrier's formidable combat capability relies on sorties,with efficient deck operations as the core to enhance sortie and recovery capabilities.First,this study develops an integrated mathematical model for carrier-based aircraft deployment,sortie,and maintenance scheduling to assist decision-makers in formulating sorties and coordinating resource allocation(e.g.,personnel,equipment),aiming to optimize the comprehensive effectiveness index of integrated carrier-based aircraft scheduling.Second,a hybrid multi-layer coded genetic algorithm(HMCGA)integrated with heuristic rules is proposed;it uses four-layer coding to resolve inter-sub-process coupling and supports integrated carrier-based aircraft scheduling,covering hangar transfer,deck transfer,aircraft maintenance support,and sortie execution.Then,case simulation shows the proposed model and algorithm effectively improve operational effectiveness and ensure accuracy.Finally,comparisons of 50 independent simulation results(PSO,DE,WOA,CPLEX)effectively validate HMCGA's superiority and universality in solving integrated carrier-based aircraft scheduling problems across fleet scales,further confirming the model and algorithm's reliability. 展开更多

Building energy systems integrating multiple energy sources can effectively reduce energy consumption and facilitate renewable energy integration.Integrating electrical energy storage(EES)into these systems helps accommodate the increasing share of renewables;however,the stochastic and intermittent nature of solar power still poses challenges to supply reliability.This study proposes a photovoltaic(PV)‐oriented storage scheduling strategy,in which short‐term PV generation forecasts are applied to guide the operation of a building power supply network consisting of photovoltaic panels,the grid,and energy storage systems.The forecasting approach employs a hybrid framework combining a Long Short‐Term Memory(LSTM)network to capture temporal dependencies,an attention mechanism to emphasise critical time steps,and a Temporal Convolutional Network(TCN)to map the enhanced features to PV outputs.Experimental evaluation using historical datasets under multiple weather conditions and time periods shows that the proposed LSTM‐Attention‐TCN model achieves a mean absolute error(MAE)of 20.45 W/m2 and a Nash–Sutcliffe efficiency(NSE)of 0.94,outperforming both standalone LSTM and TCN models as well as their hybrid variants in terms of accuracy and robustness.By providing high‐accuracy solar irradiance forecasts to guide energy storage operation and grid interaction,the proposed model enables more efficient and economical scheduling of building energy systems.Compared with an uncontrolled scenario,the LSTM‐Attention‐TCN‐based scheduling reduces the total operating cost by approximately 52.1%,and achieves an additional 16.5%reduction compared to a conventional strategy without predictive coordination.In addition,compared to other hybrid forecasting models such as LSTM‐TCN and TCN‐Attention,the proposed model achieves the lowest total cost of CNY 14.83 and demonstrates superior scheduling efficiency,thereby enhancing the stability and flexibility of building energy utilization. 展开更多

The Agile Earth Observation Satellite Scheduling Problem(AEOSSP)is a complex NP‑hard challenge that involves selecting,sequencing,and timing observation tasks to maximize imaging profits while adhering to various constraints.In our study,we developed a mixed‑integer programming model for AEOSSP,incorporating key constraints related to visible time windows and time dependencies.To tackle this,we propose an Evolutionary Adaptive Large Neighborhood Search Algorithm(evALNS)enhanced by Large Language Models(LLMs).Our work pioneers the application of LLMs to ALNS by being the first to automatically develop and evolve its critical destroy heuristics.However,a naive application of LLMs is insufficient for such a complex domain.We therefore introduce a novel Dual‑Population Co‑Evolutionary Computing Framework(DPEC)to bridge the LLM’s knowledge gap by synergizing LLM‑generated heuristics with expert‑designed ones.This co‑evolution,guided by a Functional Natural Language Embedding(FNLE)strategy and customized prompts,significantly enhances the adaptability and efficiency of ALNS.Extensive numerical experiments demonstrated the superiority of the evALNS evolved under our framework,achieving an average profit improvement of 8.48%compared to the original ALNS with expert‑designed destroy operators. 展开更多

The proliferation of carrier aircraft and the integration of unmanned aerial vehicles(UAVs)on aircraft carriers present new challenges to the automation of launch and recovery operations.This paper investigates a collaborative scheduling problem inherent to the operational processes of carrier aircraft,where launch and recovery tasks are conducted concurrently on the flight deck.The objective is to minimize the cumulative weighted waiting time in the air for recovering aircraft and the cumulative weighted delay time for launching aircraft.To tackle this challenge,a multiple population self-adaptive differential evolution(MPSADE)algorithm is proposed.This method features a self-adaptive parameter updating mechanism that is contingent upon population diversity,an asynchronous updating scheme,an individual migration operator,and a global crossover mechanism.Additionally,comprehensive experiments are conducted to validate the effectiveness of the proposed model and algorithm.Ultimately,a comparative analysis with existing operation modes confirms the enhanced efficiency of the collaborative operation mode. 展开更多

The explosive proliferation of Large Language Models(LLMs)imposes significant energy and operational burdens on Geographically Distributed Data Centers(GDDCs),thereby demanding an efficient mechanism for LLMs task scheduling.While prior geo-distributed scheduling methods reduce cost and carbon emissions by exploiting regional heterogeneity,they largely overlook model and data reuse opportunities and the uncertainty of LLM execution times.In this paper,we introduce GCOS,to the best of our knowledge,the first green scheduling framework that incorporates a dual-cache system for both data and models,while jointly optimizing task assignment and cache migration.We firstly propose a dual-cache mechanism that decouples model and data caching to enable fine-grained reuse and minimize redundant transmissions.Subsequently,we propose the Multi-Agent Cache-aware Cooperative Scheduling(MACCS)algorithm,which leverages reinforcement learning to optimize task placement with a focus on minimizing both carbon emissions and cost.Additionally,we design a lightweight execution time predictor,DiPTree,to address the high variability in task execution times.Extensive experiments on real-world datasets demonstrate that GCOS reduces overall cost by up to 92.6%and carbon emissions by 90.3%,significantly outperforming existing baselines. 展开更多

To address the issue that hybrid flow shop production struggles to handle order disturbance events,a dynamic scheduling model was constructed.The model takes minimizing the maximum makespan,delivery time deviation,and scheme deviation degree as the optimization objectives.An adaptive dynamic scheduling strategy based on the degree of order disturbance is proposed.An improved multi-objective Grey Wolf(IMOGWO)optimization algorithm is designed by combining the“job-machine”two-layer encoding strategy,the timing-driven two-stage decoding strategy,the opposition-based learning initialization population strategy,the POX crossover strategy,the dualoperation dynamic mutation strategy,and the variable neighborhood search strategy for problem solving.A variety of test cases with different scales were designed,and ablation experiments were conducted to verify the effectiveness of the improved strategies.The results show that each improved strategy can effectively enhance the performance of the IMOGWO.Additionally,performance analysis was conducted by comparing the proposed algorithm with three mature and classical algorithms.The results demonstrate that the proposed algorithm exhibits superior performance in solving the hybrid flow-shop scheduling problem(HFSP).Case validations were conducted for different types of order disturbance scenarios.The results demonstrate that the proposed adaptive dynamic scheduling strategy and the IMOGWO algorithm can effectively address order disturbance events.They enable rapid response to order disturbance while ensuring the stability of the production system. 展开更多

This paper proposes a Deep Reinforcement Learning(DRL)algorithm for user scheduling in Millimeter Wave(mmWave)networks,which utilizes Channel Knowledge Map(CKM)for knowledge transfer to enhance the learning of scheduling strategies.The user scheduling and link configuration problems are modeled as a multiqueue system.Each queue represents the data demand of an individual user.This setup allows the base station to make dynamic scheduling decisions based on changing environmental conditions.This approach facilitates efficient management of user-specific requirements while addressing the challenges posed by dynamic network environments.Our model incorporates relay selection,codebook selection,and beam tracking to support flexible and efficient resource allocation.In contrast to traditional channel model-based optimization,we design algorithms for scheduling policy pre-training using CKMs,which provide information about the channel between specific pairs of locations.Specifically,we assume that the CKM is fully available to allow the complex scheduling network to have a better starting point or follow a more favorable gradient direction through knowledge migration.This integration of CKM with knowledge transfer significantly accelerates DRL convergence and enhances performance stability.Simulation results confirmed the effectiveness of the proposed approach.Relative to the baseline methods,integrating CKM with knowledge transfer accelerated the convergence of the DRL algorithm by approximately 20%,maintained the delay within 30 milliseconds,and reduced the average queue length by nearly 30%. 展开更多

With the large-scale integration of wind and solar energy into the power grid,the power system is facing uncertainty challenges in multiple links,such as source,grid,and load.How to efficiently dispatch flexible resources,such as energy storage,has become an urgent problem to be solved.To this end,this paper considers the correlation between new energy stations due to natural conditions,uses Vine-Copula theory to describe the correlation characteristics of the output of multiple new energy stations,and proposes a wind solar new energy output scenario generation method based on Vine-Copula theory;Then,to develop the optimal scheduling and operation plan,considering the goal of minimizing operating costs within a scheduling cycle,combined with the scenario of output of wind and solar energy,an optimization and scheduling model for wind-solar-thermal-storage power system operation of multiple energy stations was constructed;On this basis,considering the difficulty in obtaining the probability distribution of load uncertainty,a risk-averse model and a risk-seeking model based on information Gap Decision Theory(IGDT)were constructed,and a multi energy station power system operation optimization scheduling method based on correlation-IGDT was proposed.By setting risk strategies and risk deviation factors,the power system operation scheduling scheme under this strategy can be obtained.Simulation experiments were conducted based on an improved IEEE39 node system for verification,and the results showed that compared to traditional methods that do not consider correlation,this method can reduce thermal power costs by 0.63%and energy storage costs by 10.56%.Meanwhile,Monte Carlo sampling analysis shows that the model has good accuracy and stability within the range of load disturbances.Further analysis shows that under the risk avoidance strategy,the maximum power variation of thermal power is controlled at 284 MW,with an average of 172 MW;while under the risk acceptance strategy,the maximum variation is 198 MW,with an average of 127 MW,significantly improving the system’s adaptability and operational efficiency to uncertain environments.The main contribution of this article is to integrate the modeling of new energy correlation with information gap decision-making and construct a power system scheduling optimization framework for multiple uncertain factors,which has good promotion value and practical application potential. 展开更多

In response to the challenges faced by unmanned swarms in mountain obstacle-breaching missions within complex terrains,such as poor task-resource coupling,lengthy solution generation times,and poor inter-platform collaboration,an unmanned swarm scheduling strategy tailored is proposed for mountain obstacle-breaching missions.Initially,by formalizing the descriptions of obstacle breaching operations,the swarm,and obstacle targets,an optimization model is constructed with the objectives of expected global benefit,timeliness,and task completion degree.A meta-task decomposition and reassembly strategy is then introduced to more precisely match the capabilities of unmanned platforms with task requirements.Additionally,a meta-task decomposition optimization model and a meta-task allocation operator are incorporated to achieve efficient allocation of swarm resources and collaborative scheduling.Simulation results demonstrate that the model can accurately generate reasonable and feasible obstacle breaching execution plans for unmanned swarms based on specific task requirements and environmental conditions.Moreover,compared to conventional strategies,the proposed strategy enhances task completion degree and expected returns while reducing the execution time of the plans. 展开更多

Under extreme weather conditions(such as hurricanes and heatwaves causing sudden drops in renewable energy output and surges in load),microgrid operations face severe challenges due to the uncertainty of renewable energy and load fluctuations.Although existing research has focused on microgrid optimal scheduling or electric vehicle integration,there has not yet been a systematic approach to multi-timescale scheduling that combines electric vehicle fleets under extreme weather scenarios,and particularly,explicit modeling of weather events and their impact on component failure rates and transmission lines is lacking.This paper proposes,for the first time,a multi-timescale optimal scheduling strategy integrated with an electric vehicle fleet,filling this gap.By constructing a microgrid model containing diesel generators,micro gas turbines,renewable energy sources,energy storage,and demand response loads,and defining four typical extreme weather scenarios(high solar&high wind,high solar&low wind,low solar&high wind,low solar&low wind)to simulate the impact of extreme events,a day-ahead and intraday coordinated framework aiming to minimize total operating costs is established.In this framework,the day-ahead stage formulates a preliminary plan based on wind and solar forecasts,while the intraday stage employs the mobile energy storage characteristics of the electric vehicle fleet for rolling adjustments to cope with renewable fluctuations and sudden load changes.Simulations based on actual data from Huai’an City in 2024 show that this strategy can significantly reduce microgrid operating costs(by 5.6%–7.2%),increase renewable energy utilization(94%–96%),reduce carbon emissions(17.8%–22.6%),and enhance the system’s economic performance and resilience under extreme weather conditions. 展开更多

The scheduling optimization and task assignment of aero-engine fleets are complex and dynamic,presenting a significant challenge in aviation engineering.This study proposes a Dual-layer Collaborative Optimization Framework(DCOF)to address these challenges.The problem is decomposed into two interrelated sub-problems,scheduling optimization and task assignment,with distinct mathematical models formulated for each.For scheduling optimization,this study proposes an Improved Gravity Particle Swarm Optimization(IGPSO)algorithm.The algorithm enhances global search capability and convergence speed through dynamic weight adjustment and constraint processing repair strategies,effectively handling dynamic variations in engine health and remaining life.For task assignment,an Improved Branch-and-Price(IB&P)method is used.This method combines column generation with branch-and-bound strategies,while integrating heuristic rules and parallel computing techniques to efficiently find optimal solutions under multi-dimensional constraints.By clearly distinguishing between operational and maintenance tasks and considering their interdependencies,the proposed DCOF better captures real operational needs,improving fleet scheduling efficiency and reliability.Experimental validation and engineering simulations confirm the method’s effectiveness,showing advantages in repair balance,task assignment balance,and minimizing engine life waste.The approach enhances both usage efficiency and maintenance management of aero-engine fleets. 展开更多

High wind-solar penetration drives integrated energy systems(IESs)to act as cross-vector buffers that absorb surplus electricity via hybrid storage,or convert it into heat and hydrogen for cross-medium energy peak shaving.However,conventional mixed-integer linear programming(MILP)solvers and static incentive schemes often struggle with the high-dimensional,strongly coupled,non-convex,and time-varying nature of electric-heat-hydrogen scheduling.Thus,we propose an end-to-end optimization framework for a renewable electric-heat-hydrogen IES,and evaluate it through offline dispatch computations and cost settlement on a 24-h simulated case study.The proposed framework incorporates a coupled power-state of charge(SOC)dual penalty mechanism to ensure consistent storage operation over time.Additionally,it includes a bidirectional incentive-based demand response(B-IDR)mapping that is differentiable and can capture asymmetric feedback in response to price fluctuations.Furthermore,a long short-term memory(LSTM)-augmented maximum-entropy soft actor-critic(SAC)scheduler is utilized for stable and efficient control in this continuous and high-dimensional setting.Comparisons with other methods under identical settings show that the proposed method achieves lower operating costs and carbon emissions,as well as improved training stability. 展开更多

With the large-scale integration of new energy sources,various resources such as energy storage,electric vehicles(EVs),and photovoltaics(PV) have participated in the scheduling of active distribution networks(ADNs),posing new challenges to the operation and scheduling of distribution networks.Aiming at the uncertainty of PV and EV,an optimal scheduling model for ADNs based on multi-scenario fuzzy set based charging station resource forecasting is constructed.To address the scheduling uncertainties caused by PV and load forecasting errors,a day-ahead optimal scheduling model based on conditional value at risk(CVaR) for cost assessment is established,with the optimization objectives of minimizing the operation cost of distribution networks and the risk cost caused by forecasting errors.An improved subtractive optimizer algorithm is proposed to solve the model and formulate day-ahead optimization schemes.Secondly,a forecasting model for dispatchable resources in charging stations is constructed based on event-based fuzzy set theory.On this basis,an intraday scheduling model is built to comprehensively utilize the dispatchable resources of charging stations to coordinate with the output of distributed power sources,achieving optimal scheduling with the goal of minimizing operation costs.Finally,an experimental scenario based on the IEEE-33 node system is designed for simulation verification.The comparison of optimal scheduling results shows that the proposed method can fully exploit the potential scheduling resources of charging stations,improving the operation stability of ADNs and the accommodution capacity of new energy. 展开更多

In this paper,we propose a new privacy-aware transmission scheduling algorithm for 6G ad hoc networks.This system enables end nodes to select the optimum time and scheme to transmit private data safely.In 6G dynamic heterogeneous infrastructures,unstable links and non-uniform hardware capabilities create critical issues regarding security and privacy.Traditional protocols are often too computationally heavy to allow 6G services to achieve their expected Quality-of-Service(QoS).As the transport network is built of ad hoc nodes,there is no guarantee about their trustworthiness or behavior,and transversal functionalities are delegated to the extreme nodes.However,while security can be guaranteed in extreme-to-extreme solutions,privacy cannot,as all intermediate nodes still have to handle the data packets they are transporting.Besides,traditional schemes for private anonymous ad hoc communications are vulnerable against modern intelligent attacks based on learning models.The proposed scheme fulfills this gap.Findings show the probability of a successful intelligent attack reduces by up to 65%compared to ad hoc networks with no privacy protection strategy when used the proposed technology.While congestion probability can remain below 0.001%,as required in 6G services. 展开更多

Some critical applications of emergency,Active Safe Driving(ASD),eV2X,and LEO communications require ultra-low delay and highly reliable transmission according to beyond 5G-Advanced(5G-A),6G,and LEO specifications.Related studies proposed various scheduling algorithms in terms of single and multiple QoS requirements.However,these approaches tend to prioritize traditional QoS requirements while neglecting crucial considerations such as bearer costs and associated benefits.Moreover,most scheduling neglects the carrying cost according to the radio resource state and the bringing reward from different types of flows.Thus,this paper proposes a novel cost-based flow scheduling(eSCFS)framework that utilizes an extended sigmoid function to dynamically prioritize flows,taking into account all relevant key factors.The principal objective is to reduce latency while optimizing the utilization of radio RB and maximizing the net benefits of 5G-A NR networks.The eSCFS method has been validated through numerical simulations,which demonstrated superior key performance metrics,including network latency,resource utilization,and overall profitability.Consequently,several objectives are thus achieved:1)analyzing the QoS requirements of various services within limited radio resources,2)proposing a novel vRB state-dependent dynamic flow scheduling and adaptive virtual radio RB management to maximize network performance. 展开更多

With the growing emphasis on intelligent agriculture,scheduling problems involving multiple harvesters in largescale croplands have attracted increasing attention.In these scenarios,harvesters collaboratively perform tasks in expansive croplands,with each harvester taking on a portion of the workload.This study defines such problems as the harvester scheduling problem with splittable workloads(HSPSW).Unlike most multi-robot task allocation problems,HSPSW requires collaboration among several harvesters and involves more harvesters than croplands.These features increase the complexity of harvester-cropland interactions.To address these challenges,this paper proposes a novel two-step iterative local search(TSILS)algorithm.A greedy strategy that prioritizes croplands with higher workloads is proposed to generate initial solutions.Subsequently,a two-step iterative search strategy is employed to obtain high-quality solutions:the first step uses a predefined objective to facilitate rapid workload allocation for feasible solutions,and the second step integrates specific neighborhood operators and finegrained local search to improve its search capability.Experimental results demonstrate that the proposed method TSILS significantly outperforms existing approaches in both algorithmic performance and computational efficiency. 展开更多
