Conventional resilience approaches that simply aim to return functions to their pre-crisis state are insufficient for effective management in today’s industrial sector. This article introduces a comprehensive and innovative framework for antifragility that can use crises as opportunities to put better safety processes in place in industries. The framework was designed drawing on data from the scientific literature in vulnerability, resilience and antifragility, and the collective wisdom of experts in the field. Criteria from this qualitative data were then prioritized using the Spherical Fuzzy Delphi (SF-Delphi) method, and finally, with the participation of expert panels, the Comprehensive Antifragility Framework was developed. The framework is structured around three pillars: Direction (responsible leadership, systematic environmental awareness, aligned policymaking), Execution (criteria for achieving antifragility in the form of human resources, organizational structure, capital and resources, data and knowledge management, technology, risk and crisis management, and organizational safety and security), and Results (the organization’s recoverability, learning, reliability, flexibility and dynamism). The proposed framework represents a comprehensive, evidence-based antifragility framework for industries seeking a secure, adaptive, and forward-thinking future, that can make them resilient to system safety crises, and able to thrive in the face of disruption.
传统的弹性方法仅仅旨在将职能恢复到危机前的状态,这对于当今工业部门的有效管理是不够的。本文介绍了一个全面和创新的反脆弱性框架,该框架可以利用危机作为机会,在工业中实施更好的安全流程。该框架的设计借鉴了脆弱性、复原力和反脆弱性方面的科学文献数据,以及该领域专家的集体智慧。然后使用球面模糊德尔菲(SF-Delphi)方法对这些定性数据中的标准进行优先级排序,最后,在专家小组的参与下,开发了综合反脆弱性框架。该框架围绕三个支柱构建:方向(负责任的领导、系统的环境意识、一致的政策制定)、执行(以人力资源、组织结构、资本和资源、数据和知识管理、技术、风险和危机管理以及组织安全和保障为形式实现反脆弱性的标准)和结果(组织的可恢复性、学习能力、可靠性、灵活性和活力)。拟议的框架代表了一个全面的、以证据为基础的反脆弱性框架,适用于寻求安全、适应性和前瞻性未来的行业,使其能够抵御系统安全危机,并能够在面临中断时蓬勃发展。

Bayesian network-based reliability analysis approaches can effectively address structural limitations inherent in complex multi-state systems. However, three challenges of high computational complexity, multiple failure states, and multi-source uncertainty in the more-electric aircraft system pose significant obstacles to achieve accurate reliability analysis. To bridge these gaps, this study proposes a dynamic reliability analysis method for complex multi-state systems of more-electric aircraft based on fuzzy support radius and Markov chain enhanced trapezoidal membership function (E-TrMF) and interval grey number-lightweight dynamic Bayesian network (EI-LDBN). First, a grey Bayesian information criterion-based dynamic Bayesian network lightweighting strategy is developed to eliminate redundant structures of the DBN in the complex multi-state systems and enhance the model efficiency, which constructs a LDBN architecture. Then, the E-TrMF is developed by an integrating trapezoidal membership function with the fuzzy support radius and a discrete-time Markov chain, which dynamically quantifies multi-failure states of key components in the multi-state systems. Subsequently, a grey conditional probability table is developed for the LDBN model by using interval grey numbers to enable failure analysis under dynamic conditions, which effectively addresses multi-source uncertainty. Finally, an EI-LDBN framework is proposed to achieve accurate and dynamic reliability analysis for the complex multi-state systems of more-electric aircraft. A case of the starter-generator system (SGS) of more-electric aircraft has been conducted, and the experiment results demonstrate that the proposed EI-LDBN method can effectively achieve the lightweight modeling and dynamic reliability analysis with 39.1% and 63% efficiency improvements compared with EI-DBN and DFT methods under multi-source uncertainty.
基于贝叶斯网络的可靠性分析方法可以有效地解决复杂多状态系统固有的结构局限性。然而,高计算复杂度、多故障状态和多源不确定性这三大挑战对实现准确的可靠性分析构成了重大障碍。为了弥补这些不足,本研究提出了一种基于模糊支持半径和马尔可夫链增强梯形隶属函数(E-TrMF)和区间灰数轻量级动态贝叶斯网络(EI-LDBN)的多电动飞机复杂多状态系统动态可靠性分析方法。首先,提出了一种基于灰色贝叶斯信息准则的动态贝叶斯网络轻量化策略,消除复杂多状态系统中DBN的冗余结构,提高模型效率,构建了LDBN体系结构;然后,利用具有模糊支持半径的梯形隶属度积分函数和离散马尔可夫链建立E-TrMF,动态量化多状态系统中关键部件的多失效状态;随后,利用区间灰数建立LDBN模型的灰色条件概率表,实现动态条件下的失效分析,有效地解决了多源不确定性问题。最后,提出了一个EI-LDBN框架,以实现对多电动飞机复杂多状态系统的精确动态可靠性分析。以多电动飞机起动-发电机系统(SGS)为例,实验结果表明,在多源不确定性下,与EI-DBN和DFT方法相比,所提出的EI-LDBN方法能有效实现轻量化建模和动态可靠性分析,效率分别提高39.1%和63%。

With the expansion of subway infrastructures across urban China, deep excavations have become increasingly common. Predicting deformation during excavation is crucial during the construction of Mass Rapid Transportation (MRT) station buildings, as excessive displacement may result in severe economic and safety consequences. Traditional numerical methods and existing AI models fail to simultaneously process time-dependent and time-independent factors, limiting their predictive accuracy and adaptability. To address this problem, this study proposes a novel Artificial Satellite Search Algorithm-Neural Network-Revolving Gate Fourier Transformation (ASSA-NN-RGFT) framework with three key innovations: (1) a dual-stream architecture that separately processes sequential data through RGFT’s frequency-domain analysis and non-sequential data through NN; (2) a revolving mechanism that performs iterative FFT-iFFT transformations with cross-attention, capturing periodic deformation patterns missed by conventional recurrent models; and (3) automated ASSA-based hyperparameter optimization that eliminates the need for manual calibration. This model, trained to predict diaphragm wall deflection and ground settlement, is a tool tailored for real-time deformation monitoring and early warning. In comparison against six advanced AI models, the proposed ASSA-NN-RGFT achieved the best overall performance, earning the lowest error (wall displacement: MAPE = 3.54 %; ground settlement: MAPE = 5.78 %) and highest correlation metric (wall displacement: R2 = 0.952; ground settlement: R2 = 0.842). Real-world validation across ten MRT projects achieved 85.42 % high-accuracy predictions for wall displacement and 5.89 % average error for ground settlement. The exceptional predictive performance, dynamic adaptability, and strong reliability demonstrated by the proposed ASSA-NN-RGFT model support its viability as a decision-support system in excavation risk management.
随着中国城市地铁基础设施的扩张,深基坑开挖越来越普遍。在捷运车站建筑施工过程中,开挖变形预测是至关重要的,过大的位移会造成严重的经济和安全后果。传统的数值方法和现有的人工智能模型不能同时处理时间相关和时间无关的因素,限制了它们的预测精度和适应性。为了解决这一问题,本研究提出了一种新的人工卫星搜索算法-神经网络-旋转门傅里叶变换(ASSA-NN-RGFT)框架,该框架具有三个关键创新:(1)双流架构,通过RGFT的频域分析分别处理顺序数据和通过神经网络处理非顺序数据;(2)一种旋转机制,可进行交叉注意的迭代FFT-iFFT变换,捕捉常规循环模型遗漏的周期性变形模式;(3)基于assa的自动超参数优化,消除了手动校准的需要。该模型经过训练,可以预测地下连续墙的挠度和地面沉降,是为实时变形监测和预警量身定制的工具。与6种先进的人工智能模型相比,本文提出的ASSA-NN-RGFT综合性能最佳,误差最小(墙体位移:MAPE = 3.54%,地面沉降:MAPE = 5.78%),相关系数最高(墙体位移:R2 = 0.952,地面沉降:R2 = 0.842)。在10个MRT项目的实际验证中,墙体位移的高精度预测达到85.42%,地面沉降的平均误差达到5.89%。所提出的ASSA-NN-RGFT模型具有优异的预测性能、动态适应性和较强的可靠性,支持其作为开挖风险管理决策支持系统的可行性。

Accurate monitoring of the spatial position of cable dome structure nodes is crucial for their structural safety. Traditional measurement methods are inefficient, while existing visual techniques are limited by challenges such as the small scale of node targets, strong background interference, and insufficient localization accuracy. To address this, this paper proposes a knowledge-guided perception-solution collaborative framework, achieving automated reconstruction from UAV images to 3D spatial coordinates. This framework first constructs a multi-module optimized UAV-YOLOv11 detection model. By integrating Bi-level Routing Attention, lightweight convolution, and Normalized Wasserstein Distance loss, the detection accuracy [email protected]:0.95 is improved to 88.7%. In the reconstruction stage, by introducing geometric, topological, and symmetry constraints derived from the MATLAB form-finding algorithm, Python is guided to achieve coordinate back-projection and optimization solution, forming an inverse reconstruction mechanism, ultimately achieving an average point measurement accuracy of 2.72 cm. This research provides a reliable technical path for the construction and health monitoring of large-span spatial structures, promoting the practical application of knowledge-embedded engineering informatics methods in structural monitoring.

Tool breakage monitoring (TBM) during machining processes is crucial for ensuring manufacturing safety and product quality. Although data-driven methods have made significant progress in the field of TBM, existing studies generally overlook the intrinsic correlation between tool breakage and wear processes, as the probability and severity of tool breakage vary with wear accumulation. Meanwhile, conservative process parameters in industrial practices lead to a scarcity of breakage samples, and the normal samples caused by fluctuations in working conditions exhibit multiple pattern distributions, which further increase monitoring difficulties. To address these issues, this paper proposes a novel multi-task sequential network that integrates wear information to achieve tool breakage monitoring. Unlike traditional multi-task learning (MTL), this method jointly learns tool wear prediction and breakage monitoring tasks in a sequential manner. The two tasks share a feature extraction module, and the predicted continuous wear value is fed as conditional information into the subsequent breakage monitoring module, enabling the monitoring model to adapt to different wear states. Additionally, the weighted multi-scale distance (WMSD) loss function designed for the breakage monitoring module integrates Euclidean distance, angular difference, and Latent feature distance, enhancing the capability to model the distribution pattern of normal samples and strengthening its robustness. Experimental findings indicate that the proposed method achieved favorable results on both the actual machining dataset of aerospace engine casings and the PHM2010 dataset, validating its effectiveness and broad applicability in practical scenarios.
加工过程中刀具破损监测是保证生产安全和产品质量的重要手段。虽然数据驱动方法在TBM领域取得了重大进展,但现有研究普遍忽略了刀具断裂与磨损过程之间的内在相关性,刀具断裂的概率和严重程度随着磨损的积累而变化。同时,工业实践中工艺参数的保守性导致破损样品的稀缺,而工作条件波动导致的正常样品呈现多模式分布,进一步增加了监测难度。针对这些问题,本文提出了一种集成磨损信息的多任务序列网络来实现刀具破损监测。与传统的多任务学习(MTL)不同,该方法以顺序的方式共同学习刀具磨损预测和破损监测任务。这两个任务共用一个特征提取模块,并将预测的连续磨损值作为条件信息馈送到后续的破损监测模块中,使监测模型能够适应不同的磨损状态。此外,针对破损监测模块设计的加权多尺度距离(WMSD)损失函数集成了欧氏距离、角差和潜特征距离,增强了对正态样本分布模式的建模能力,增强了其鲁棒性。实验结果表明,该方法在航空发动机机壳实际加工数据集和PHM2010数据集上均取得了较好的结果,验证了该方法的有效性和在实际场景中的广泛适用性。

The major petroleum projects under the Belt and Road Initiative (BRI) encounter intricate hazard problems. Establishing a comprehensive and scientific hazard monitoring indicator system is important to realize early identification and proactive warning of risks. Therefore, this study innovatively proposes the “Dual-Path Grounded Theory” (DPGT) as a new paradigm for human–machine collaborative qualitative research. The paradigm combines the depth of human analysis with the broadness of LLMs’ processing through a system that allows for parallel coding, cross-validation, and complementary integration between human and LLM paths. It overcomes the limitations of depending merely on ineffective manual analysis or unreliable fully automatic methods. In implementation, the human-driven path utilizes the KeyBERT model and K-means clustering algorithm to help complete the three stages of coding. The LLM-driven path assesses the performance of DeepSeek-R1, Llama3, and Qwen3 models at various coding stages and chooses DeepSeek-R1 as the main engine. This is combined with Retrieval-Augmented Generation (RAG) to build a hybrid LLM deployment architecture (RAG-HLLM), making full use of superior cloud-based reasoning abilities and protecting local data privacy. According to the DPGT framework, after several rounds of integration and screening, a hazard monitoring indicator system including 2 major categories, 8 first-level indicators, 27 second-level indicators, and 109 specific factors was finally established. Validation indicates that this system has passed the theoretical saturation test and has achieved a recall rate of 92.61% on the International Association of Oil and Gas Producers (IOGP) standard database, which greatly surpasses the results obtained from single-path methods. Methodologically, this study pioneers a new paradigm for human–machine collaborative qualitative research. Technologically, the proposed hybrid architecture balances privacy concerns with processing efficiency. Practically, it provides a dependable tool for safety management in major energy projects, exhibiting significant theoretical value and broad engineering applicability.
“一带一路”倡议下的重大石油项目面临复杂的风险问题。建立全面、科学的灾害监测指标体系,是实现风险早期识别和主动预警的重要手段。因此,本研究创新性地提出了“双路径扎根理论”(Dual-Path Grounded Theory, DPGT)作为人机协同定性研究的新范式。该范式通过一个系统将人类分析的深度与法学硕士处理的广度相结合,该系统允许并行编码、交叉验证以及人类和法学硕士路径之间的互补集成。它克服了仅仅依赖无效的人工分析或不可靠的全自动方法的局限性。在实现中,人为驱动的路径利用KeyBERT模型和K-means聚类算法来帮助完成编码的三个阶段。llm驱动路径评估了DeepSeek-R1、Llama3和Qwen3模型在不同编码阶段的性能,并选择DeepSeek-R1作为主引擎。这与检索增强生成(RAG)相结合,构建混合LLM部署架构(RAG- hllm),充分利用卓越的基于云的推理能力并保护本地数据隐私。根据DPGT框架,经过多轮整合筛选,最终建立了包括2大类、8个一级指标、27个二级指标、109个具体因子的危害监测指标体系。验证表明,该系统通过了理论饱和测试,在国际石油天然气生产商协会(IOGP)标准数据库上的召回率达到92.61%,大大超过了单路径方法的结果。在方法上,本研究开创了人机协作定性研究的新范式。从技术上讲,提出的混合架构平衡了隐私问题和处理效率。在实际应用中,为重大能源项目的安全管理提供了可靠的工具,具有重要的理论价值和广泛的工程适用性。

Therefore, this study innovatively proposes the “Dual-Path Grounded Theory” (DPGT) as a new paradigm for human–machine collaborative qualitative research. The paradigm combines the depth of human analysis with the broadness of LLMs’ processing through a system that allows for parallel coding, cross-validation, and complementary integration between human and LLM paths. It overcomes the limitations of depending merely on ineffective manual analysis or unreliable fully automatic methods. In implementation, the human-driven path utilizes the KeyBERT model and K-means clustering algorithm to help complete the three stages of coding. The LLM-driven path assesses the performance of DeepSeek-R1, Llama3, and Qwen3 models at various coding stages and chooses DeepSeek-R1 as the main engine. This is combined with Retrieval-Augmented Generation (RAG) to build a hybrid LLM deployment architecture (RAG-HLLM), making full use of superior cloud-based reasoning abilities and protecting local data privacy. According to the DPGT framework, after several rounds of integration and screening, a hazard monitoring indicator system including 2 major categories, 8 first-level indicators, 27 second-level indicators, and 109 specific factors was finally established. Validation indicates that this system has passed the theoretical saturation test and has achieved a recall rate of 92.61% on the International Association of Oil and Gas Producers (IOGP) standard database, which greatly surpasses the results obtained from single-path methods. Methodologically, this study pioneers a new paradigm for human–machine collaborative qualitative research. Technologically, the proposed hybrid architecture balances privacy concerns with processing efficiency. Practically, it provides a dependable tool for safety management in major energy projects, exhibiting significant theoretical value and broad engineering applicability.</div></div>","PeriodicalId":50941,"journal":{"name":"Advanced Engineering Informatics","volume":"71 ","pages":"Article 104340"},"PeriodicalIF":9.9,"publicationDate":"2026-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146022933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Machining feature recognition plays a crucial role in process planning, as it assists in process arrangement by extracting dimensional and geometric information, and serves as a key step toward automatic programming. The recognition accuracy directly affects the quality of tool paths, Especially in the discrimination of similar machining features, features such as holes and shafts often exhibit a high degree of similarity in both geometric appearance and topological structure. Existing deep learning methods struggle to capture the underlying topological relationships among machining features and therefore tend to misclassify highly similar features as the same category. This misidentification adversely affects subsequent process planning and can significantly degrade machining quality and overall manufacturing efficiency. To address this issue, we propose the Machining Similar Feature Recognition Network based on a Kolmogorov–Arnold-Augmented Graph Neural Mixer (MSFRNet). Among these components, Kolmogorov–Arnold Network(KAN) provides learnable spline functions capable of accurately fitting arbitrarily complex geometric or topological mappings, making it more sensitive to intricate geometric relationships. Based on this advantage,KAN is incorporated into the local feature learning stage of the Graph Neural Network(GNN) to enhance the model’s capacity for fine-grained local geometric approximation. Optimizing the local and global feature vectors in GNN using KAN. Ultimately enhancing the recognition capability of MSFRNet for typical machining features. Meanwhile, the concepts of convexity,concavity and openness are introduced to further improve the discrimination of similar machining features. Convex and concave connections reflect the topological relationships between adjacent surfaces and serve as reliable indicators for distinguishing features with highly similar shapes. In addition, openness enables the detection of whether the topological boundary of a machining feature is open or closed, providing an additional criterion for differentiating certain types of similar machining features. The purpose is to leverage these two criteria to enhance the recognition capability of MSFRNet for similar machining features. Extensive experiments on publicly available benchmark datasets demonstrate that MSFRNet achieves outstanding performance in machining feature recognition tasks, reaching an accuracy of 99.95%. In the task of recognizing similar machining features, the method achieves an accuracy of 98.6%.
加工特征识别通过提取尺寸和几何信息来辅助工艺安排,是实现自动编程的关键步骤,在工艺规划中起着至关重要的作用。识别精度直接影响刀具轨迹的质量,特别是在相似加工特征的识别中,孔和轴等特征往往在几何外观和拓扑结构上都表现出高度的相似性。现有的深度学习方法难以捕捉加工特征之间的底层拓扑关系,因此往往将高度相似的特征错误地分类为同一类别。这种错误识别会对后续的工艺规划产生不利影响,并会显著降低加工质量和整体制造效率。为了解决这一问题,我们提出了基于Kolmogorov-Arnold-Augmented Graph Neural Mixer (MSFRNet)的加工相似特征识别网络。在这些组件中,Kolmogorov-Arnold Network(KAN)提供了可学习的样条函数,能够精确拟合任意复杂的几何或拓扑映射,使其对复杂的几何关系更加敏感。基于这一优势,将KAN纳入到图神经网络(GNN)的局部特征学习阶段,增强模型的细粒度局部几何逼近能力。利用KAN优化GNN中的局部和全局特征向量。最终提高了MSFRNet对典型加工特征的识别能力。同时,引入了凸性、凹性和开放性的概念,进一步提高了对相似加工特征的识别能力。凸和凹连接反映了相邻表面之间的拓扑关系,是区分形状高度相似的特征的可靠指标。此外,开放性可以检测加工特征的拓扑边界是开放的还是封闭的,为区分某些类型的类似加工特征提供了额外的标准。目的是利用这两个准则来增强MSFRNet对相似加工特征的识别能力。在公开可用的基准数据集上进行的大量实验表明,MSFRNet在加工特征识别任务中取得了出色的性能,准确率达到99.95%。在相似加工特征的识别任务中,该方法的准确率达到了98.6%。

Causal feature selection framework for stable soft sensor modeling based on time-delayed cross mapping 基于时延交叉映射的稳定软传感器建模因果特征选择框架

Soft sensor modeling plays a crucial role in process monitoring. Causal feature selection can enhance the performance of soft sensor models in industrial applications. However, existing methods ignore two critical characteristics of industrial processes. Firstly, causal relationships between variables always involve time delays, whereas most causal feature selection methods investigate causal relationships in the same time dimension. Secondly, variables in industrial processes are often interdependent, which contradicts the decorrelation assumption of traditional causal inference methods. Consequently, soft sensor models based on existing causal feature selection approaches often lack sufficient accuracy and stability. To overcome these challenges, this paper proposes a causal feature selection framework based on time-delayed cross mapping. Time-delayed cross mapping employs state space reconstruction to effectively handle interdependent variables in causality analysis, and considers varying causal strength across time delay. Time-delayed convergent cross mapping (TDCCM) is introduced for total causal inference, and time-delayed partial cross mapping (TDPCM) is developed for direct causal inference. Then, in order to achieve automatic feature selection, an objective feature selection strategy is presented. The causal threshold is automatically determined based on the model performance on the validation set, and the causal features are then selected. Two real-world case studies show that TDCCM achieves the highest average performance, while TDPCM improves soft sensor stability and performance in the worst scenario. On average over the two cases, TDCCM decreases root mean square error (RMSE) by about 8.93% compared with the best existing feature selection method, and TDPCM further decreases RMSE in the worst scenario by about 7.69% relative to TDCCM. The code is publicly available at https://github.com/dirge1/TDPCM.
软测量建模在过程监控中起着至关重要的作用。在工业应用中,因果特征选择可以提高软测量模型的性能。然而,现有的方法忽略了工业过程的两个关键特征。首先,变量之间的因果关系总是涉及到时间延迟,而大多数因果特征选择方法在同一时间维度上考察因果关系。其次,工业过程中的变量往往是相互依存的,这与传统因果推理方法的去相关假设相矛盾。因此,基于现有因果特征选择方法的软测量模型往往缺乏足够的精度和稳定性。为了克服这些挑战,本文提出了一种基于时滞交叉映射的因果特征选择框架。时滞交叉映射在因果分析中采用状态空间重构来有效处理相互依赖的变量,并考虑了不同时间延迟的因果强度。在全因果推理中引入了延时收敛交叉映射(TDCCM),在直接因果推理中发展了延时部分交叉映射(TDPCM)。然后,为了实现自动特征选择,提出了一种客观特征选择策略。根据模型在验证集上的性能自动确定因果阈值,然后选择因果特征。两个实际案例研究表明,TDCCM实现了最高的平均性能,而TDPCM在最坏的情况下提高了软传感器的稳定性和性能。在两种情况下,TDCCM平均比现有最佳特征选择方法降低了约8.93%的均方根误差(RMSE), TDPCM在最坏情况下比TDCCM进一步降低了约7.69%的RMSE。该代码可在https://github.com/dirge1/TDPCM上公开获得。

Nowadays, the proliferation of industrial internet of things brings the skyrocketing rise in large scale data analysis and processing. As the base to realize industrial intelligence, complex industrial applications are usually accompanied by computational workflows, which typically run in heterogeneous computing resources on cloud, and many factors such as makespan, cost, reliability, energy consumption and load balancing need to be optimized simultaneously. As an NP-hard problem, how to determine proper computing nodes for each task of workflow application with many tightly coupled performance concerns is extraordinarily challenging. Focusing on this many-objective optimization problem, we present a novel learnable co-evolutionary scheduler where multiple learnable offspring generators are integrated and work cooperatively toward robust search capability, the limited computational budgets are invested into multiple generators automatically by learning from historical successful experience and exploiting heuristic information. In addition, an adaptive cluster based ranking mechanism is devised to preserve prominent solutions in environmental selection of many-objective space, which is expected to leverage the solution diversity and expedite the convergence. Empirical studies on real-life workflows and extensive synthetic benchmark test suites confirm that our proposal outperforms or is at least comparable to other state-of-the-art contenders.
如今,工业物联网的普及带来了大规模数据分析和处理的飞速发展。复杂的工业应用作为实现工业智能的基础,通常伴随着计算工作流,这些工作流通常运行在云上的异构计算资源中,需要同时优化完工时间、成本、可靠性、能耗和负载均衡等诸多因素。作为一个np困难问题,如何为具有许多紧密耦合性能关注的工作流应用程序的每个任务确定合适的计算节点是非常具有挑战性的。针对这一多目标优化问题,提出了一种新型的可学习协同进化调度算法,该算法将多个可学习子代生成器集成在一起,通过学习历史成功经验和利用启发式信息,将有限的计算预算自动投入到多个生成器中,以实现鲁棒搜索能力。此外,设计了一种基于自适应聚类的排序机制,在多目标空间环境选择中保留突出的解,从而利用解的多样性,加快收敛速度。对现实工作流程和广泛的综合基准测试套件的实证研究证实,我们的建议优于或至少与其他最先进的竞争者相媲美。
