Life Cycle Assessment (LCA) often faces challenges such as low data transparency, limited traceability, and poor data sharing among entities. To address these issues, this study develops a blockchain based life cycle information management system that adopts a front end and back end separation architecture and integrates on chain and off chain collaborative storage. The system supports version tracking, auditing, and secure data sharing through unique identifiers, permission control, and smart contracts. Using bogie frame as a case study, it was validated under real data scenarios, showing zero error rates and high consistency in integrity and transparency. Performance tests indicated average response times of 30–60 ms and on chain delays of about 2.8 s, with stable operation at medium scale. The proposed framework enhances transparency, reliability, and efficiency, providing a scalable digital solution for integrating blockchain with LCA in sustainable manufacturing.

Crest settlement is a key indicator of seismic deformation in rockfill dams. However, the absence of a dedicated seismic settlement database and the incomplete recording of key parameters hinder systematic assessments of seismic damage. To address these limitations, this study develops a comprehensive database documenting crest settlement and associated dam damage. A novel Data–Physics Hybrid-Driven (DPHD) imputation method is introduced to reconstruct missing parameters, and its accuracy is rigorously validated. Single-factor analyses elucidate the mechanisms governing crest settlement, whereas grey relational analysis identifies the dominant influencing factors—namely, dam resistance, seismic-acceleration intensity, near-field effects, and epicentral distance. Based on the database and analytical results, seismic-settlement control standards corresponding to different damage levels are further proposed. The results demonstrate that the DPHD method effectively resolves data gaps, and the derived settlement standards provide practical guidance for seismic design and settlement-mitigation strategies in rockfill dams.
坝顶沉降是堆石坝地震变形的重要指标。然而,由于缺乏专门的地震沉降数据库和关键参数的不完整记录,阻碍了对地震损害的系统评估。为了解决这些限制,本研究开发了一个全面的数据库,记录波峰沉降和相关的大坝破坏。提出了一种新的数据物理混合驱动(DPHD)插值方法来重建缺失参数,并对其精度进行了严格验证。单因素分析阐明了控制波峰沉降的机制,而灰色关联分析确定了主要的影响因素,即大坝阻力、地震加速度强度、近场效应和震中距离。在数据库和分析结果的基础上,进一步提出了不同震害等级对应的地震沉降控制标准。结果表明,DPHD方法有效地解决了数据缺口,推导出的沉降标准对堆石坝的抗震设计和沉降减缓策略具有实用的指导意义。

Pollution of airborne dust particle poses serious challenges to the environment and human health, and the operational reliability of precision measurement laboratories, particularly in regions characterized by harsh climatic conditions. Accurate prediction of dust particle concentrations remains challenging due to complex nonlinear interactions among meteorological factors and the limited availability of fully labeled environmental datasets. Therefore, there is a critical need for advanced and robust modeling approaches that can improve the prediction accuracy while handling data uncertainty and sparsity. In this article, several regression analysis (models) and label propagation approaches have been applied and examined for predicting the airborne dust particle concentrations within the national measurement & calibration center (NMCC), saudi standards metrology and quality organization (SASO), Riyadh, Saudi Arabia. Six different models, namely, random forest regression (RFR), K-nearest neighbours regression (KNNR), cosine similarity-based label propagation regression (CS_LPR), adaptive fuzzy entropy-based label propagation regression (AFE_LPR), random forest-based label propagation (RF_LPR), and KNN-based label propagation (KNN_LPR) models were developed for forecasting the airborne dust particle levels and investigated the performance of each model. The airborne dust particles were experimentally counted using an advanced particle measurement technique by considering various factors, namely, air quality, environmental temperature, humidity, wind speed, and rainfall. The performance of the developed models was checked using different metrics such as mean absolute error (MAE), mean squared error (MSE), root mean squared error (RMSE), R2, adjusted R2, mean absolute scaled error (MASE), and Huber loss. The results obtained from each model demonstrate that the label propagation models (CS_LPR, AFE_LPR, RF_LPR, and KNN_LPR) have exhibited well fitted one, and achieved excellent accuracy on the test data (R2 > 0.98) due to effective learning of the training data, including noise and specific patterns present in the dataset. The finding obtained through this research work emphasize that the label propagation methods can effectively address the prediction challenges in environmental monitoring tasks. This paper addresses the comparative performance and features of each approach in airborne dust particle prediction.
空气中粉尘颗粒的污染对环境和人类健康以及精密测量实验室的运行可靠性构成严重挑战,特别是在气候条件恶劣的地区。由于气象因素之间复杂的非线性相互作用和完全标记的环境数据集的有限可用性,对尘粒浓度的准确预测仍然具有挑战性。因此,在处理数据不确定性和稀疏性的同时,迫切需要先进和健壮的建模方法来提高预测精度。在本文中,几种回归分析(模型)和标签传播方法已经应用和检验了预测空气中的尘埃颗粒浓度在国家测量和校准中心(NMCC),沙特标准计量和质量组织(SASO),沙特阿拉伯利雅得。建立了随机森林回归(RFR)、k近邻回归(KNNR)、基于余弦相似度的标签传播回归(CS_LPR)、基于自适应模糊熵的标签传播回归(AFE_LPR)、基于随机森林的标签传播(RF_LPR)和基于knn的标签传播(KNN_LPR) 6种不同的空气粉尘水平预测模型,并对每种模型的性能进行了研究。通过综合考虑空气质量、环境温度、湿度、风速和降雨量等因素,采用先进的粒子测量技术对空气中的尘埃粒子进行了实验计数。采用平均绝对误差(MAE)、均方误差(MSE)、均方根误差(RMSE)、R2、调整后R2、平均绝对缩放误差(MASE)和Huber损失等指标对所建立模型的性能进行检验。从每个模型得到的结果表明,标签传播模型(CS_LPR, AFE_LPR, RF_LPR和KNN_LPR)具有良好的拟合性,并且由于有效地学习了训练数据,包括数据集中存在的噪声和特定模式,因此在测试数据上取得了良好的准确性(R2 > 0.98)。研究结果强调了标签传播方法可以有效地解决环境监测任务中的预测挑战。本文讨论了各种方法在空气尘埃粒子预测中的比较性能和特点。

Modern datasets often exhibit high skewness and non-monotonic hazard rate patterns. These features reveal a gap in many traditional distributions, which struggle to model such behavior accurately. This study introduces the inverse power Akshaya distribution (IPAkD) to address this limitation. The IPAkD is developed using the inverse power transformation and provides greater flexibility for modeling right-skewed data. It has closed-form probability density function and cumulative distribution function expressions, and its hazard rate can capture an upside-down bathtub-shaped pattern. Key properties such as moments, extropy, and order statistics are also presented. The model parameters were estimated using several methods. The IPAkD was applied to seven right-skewed real datasets and compared with twelve existing models using twelve evaluation measures. The findings show that the IPAkD offers a better fit and stronger practical performance, filling an important gap in modeling complex right-skewed datasets.
现代数据集经常表现出高偏度和非单调的危险率模式。这些特征揭示了许多传统发行版的差距,它们难以准确地模拟这种行为。本研究引入逆幂Akshaya分布(IPAkD)来解决这一限制。IPAkD是使用逆功率变换开发的,为右倾斜数据建模提供了更大的灵活性。它具有封闭型的概率密度函数和累积分布函数表达式,其危险率可以捕捉到一个倒立的浴缸形状。关键属性,如矩,外向型和顺序统计也提出。采用多种方法对模型参数进行了估计。IPAkD应用于7个右偏真实数据集,并使用12个评价指标与12个现有模型进行比较。研究结果表明,IPAkD具有更好的拟合和更强的实用性能,填补了复杂右倾斜数据集建模的重要空白。

Intercity corporate networks have an important role in increasing enterprise efficiency and competitiveness. Therefore, they act as an engine for economic development and regional cooperation. The ability to predict and model them appropriately will lay the foundation for decision-making and optimization of the distribution of resources in such a way that effective communication across corporations is ensured. This paper presents an approach to the predictive modeling of a support vector regression to simulate the intercity corporation network. Precise data prediction and transmission across the network are very important for any simulated model to be deployed. Apart from optimization methods, the incorporation of meta-heuristic algorithms elevates the accuracy and speed of the forecast. This research investigates six optimization methods and their hybridization with SVR, with a critical investigation and comparison in terms of statistical performance metrics. It can be observed from the results that both the Manta-Ray Optimizer and Battle Royale Optimizer result in good performances with low error rates and high values of R and R2. In this regard, the Manta-Ray Optimizer is chosen as the final optimizer for the proposed hybrid algorithm since it had an R2 value of 0.9430 in the test data, followed by the Salp Swarm Optimization Algorithm with an R2 value of 0.9410, and the Battle Royale Optimizer with the lowest R2 value of 0.9320 observed for the test data.
城际企业网络对提高企业效率和竞争力具有重要作用。因此,它们是经济发展和区域合作的引擎。适当预测和建模的能力将为决策和优化资源分配奠定基础,从而确保公司之间的有效沟通。本文提出了一种基于支持向量回归的城际企业网络预测建模方法。准确的数据预测和跨网络传输对于任何模拟模型的部署都是非常重要的。除了优化方法外,元启发式算法的结合提高了预测的准确性和速度。本文研究了六种优化方法及其与SVR的融合,并从统计性能指标方面进行了批判性的调查和比较。从结果可以看出,Manta-Ray Optimizer和Battle Royale Optimizer都具有较好的性能,错误率低,R和R2值高。因此,我们选择Manta-Ray Optimizer作为混合算法的最终优化器,因为在测试数据中,Manta-Ray Optimizer的R2值为0.9430,其次是Salp Swarm Optimization algorithm, R2值为0.9410,在测试数据中,Battle Royale Optimizer的R2值最低,为0.9320。

High-precision machine tools are vital in modern manufacturing, yet their accuracy is often degraded by thermal errors. Traditional models lack cross-machine generalization and rely heavily on large labeled data. This paper proposes a thermal error modeling approach combining an encoder–decoder temporal convolutional network (ED-TCN) with representation subspace distance (RSD) transfer learning for cross-machine prediction. The encoder–decoder structure captures multi-scale features via dilated causal convolutions and residual blocks, enhancing long-term dependency modeling. The RSD-based domain adaptation reduces inter-machine distribution discrepancies while preserving feature scales. Through semi-supervised transfer learning, high-precision prediction is achieved using only 20% of labeled target data, greatly reducing collection costs. Experimental results on two different machine tools under three operating conditions demonstrate outstanding performance, achieving an R2 of 99.5%, an RMSE of 1.201 µm, and an MAE of 1.008 µm, thereby confirming the practicality and robustness of the proposed method.
高精度机床在现代制造业中至关重要,但其精度往往因热误差而降低。传统模型缺乏跨机器泛化,并且严重依赖于大量标记数据。本文提出了一种将编码器-解码器时序卷积网络(ED-TCN)与表征子空间距离(RSD)迁移学习相结合的热误差建模方法,用于跨机器预测。编码器-解码器结构通过扩展的因果卷积和残差块捕获多尺度特征,增强了长期依赖建模。基于rsd的领域自适应减少了机器间分布差异,同时保留了特征尺度。通过半监督迁移学习,仅使用20%的标记目标数据即可实现高精度预测,大大降低了收集成本。在两种不同机床上进行的三种工况下的实验结果表明,该方法的拟合R2为99.5%,RMSE为1.201µm, MAE为1.008µm,验证了该方法的实用性和鲁棒性。

The integration of intermittent renewable energy sources introduces significant operational uncertainties, challenging the economic efficiency and reliability of power systems. Centralized energy management strategies for multi-microgrid (MMG) networks face critical limitations in scalability, data privacy, and resilience to single-point failures. This study presents a scalable, privacy-preserving, and decentralized energy management framework for cooperative MMG networks to enhance operational efficiency and resilience. To achieve this, a novel consensus-based decentralized optimization algorithm is proposed, utilizing the Alternating Direction Method of Multipliers (ADMM), which decomposes the global optimal energy management problem into local subproblems that can be solved independently by each microgrid (MG). The method enables real-time coordination through iterative updates of local variables, consensus on power exchanges, and minimal information sharing—only power flows and dual variables between neighboring MGs. Simulation results on a modified 33-bus system with three interconnected MGs demonstrate that the proposed framework effectively balances supply and demand, optimizes energy storage utilization, and facilitates peer-to-peer energy trading, achieving lower operational costs and faster convergence compared to conventional ADMM, dual decomposition, consensus gradient, and proximal message passing methods. The proposed ADMM-based consensus framework provides a robust, scalable, and economically efficient solution for decentralized energy management in cooperative MMG systems.
间歇性可再生能源的整合引入了重大的运行不确定性,对电力系统的经济效率和可靠性提出了挑战。多微电网(MMG)网络的集中能源管理策略在可扩展性、数据隐私和单点故障恢复能力方面面临着严重的限制。本研究提出了一种可扩展、隐私保护和分散的能源管理框架,用于合作MMG网络,以提高运营效率和弹性。为此,提出了一种新的基于共识的分散优化算法,利用乘数交替方向法(ADMM)将全局最优能量管理问题分解为局部子问题,每个微电网(MG)都可以独立解决这些子问题。该方法通过局部变量的迭代更新、电力交换的共识以及相邻mg之间仅限潮流和双变量的最小信息共享实现实时协调。仿真结果表明,与传统的ADMM、对偶分解、共识梯度和近端消息传递方法相比,该框架有效地平衡了供需,优化了储能利用率,促进了点对点能源交易,实现了更低的运营成本和更快的收敛速度。提出的基于admm的共识框架为合作MMG系统中的分散能源管理提供了一个强大、可扩展且经济高效的解决方案。

To ensure accurate identification and control of coal and gangue during top-coal caving mining, this study proposes a multimodal information fusion method integrating vibration data, infrared images, and RGB images. The vibration signals were transformed into time–frequency spectrograms using the Continuous Wavelet Transform (CWT), and a Wasserstein Generative Adversarial Network with Gradient Penalty (WGAN-GP) was employed for data augmentation to mitigate sample scarcity. Comparative experiments between early and late fusion strategies revealed that the late fusion approach based on the ResNet architecture yielded superior performance. With the optimal combination of vibration spectrograms (ResNet-18), infrared images (ResNet-50), and RGB images (ResNet-18), the model achieved a favorable balance between high accuracy and computational efficiency. Finally, a multi-domain co-simulation control system was developed for verification, demonstrating an average response time below 0.66 s under various rock-mixing ratio conditions. The proposed framework offers an effective technical solution for high-efficiency, clean coal production.
为了保证放顶煤开采过程中煤、矸石的准确识别和控制,本研究提出了一种将振动数据、红外图像和RGB图像相结合的多模态信息融合方法。采用连续小波变换(CWT)将振动信号转换为时频谱图,并采用WGAN-GP (Wasserstein梯度惩罚生成对抗网络)进行数据增强,以缓解样本稀缺性。早期和晚期融合策略的对比实验表明,基于ResNet架构的晚期融合策略具有更好的性能。该模型通过对振动谱图(ResNet-18)、红外图像(ResNet-50)和RGB图像(ResNet-18)的优化组合,在高精度和计算效率之间取得了良好的平衡。最后,开发了一个多域联合仿真控制系统进行验证,在不同的岩石混合比条件下,平均响应时间小于0.66 s。提出的框架为高效、清洁的煤炭生产提供了有效的技术解决方案。

This paper proposes FUCOMSort, a novel consensus-based multi-criteria sorting method that utilizes the Full COnsistency Method (FUCOM) to categorize alternatives into predefined categories. By reducing pairwise comparisons, it significantly improves sorting efficiency and classification model consistency. Specifically, the LPHFSs Dombi Weighted Average (LPHFDWA) operator is introduced to effectively aggregate expert information. In addition, a redefined hybrid centrality measure, combining trust relationships with K-core decomposition, is proposed to evaluate their substantial impact on the classification outcomes. A consensus-reaching process is further constructed using trust networks and regret theory, addressing conflicts in expert evaluations. FUCOM is extended to the LPHFSs environment, incorporating both subjective and objective weights through linear equations. The proposed FUCOMSort method reduces pairwise comparisons to just n-1, thereby substantially improving efficiency in large-scale multi-criteria sorting problems. To validate the proposed method, we applied it to the classification of green patent values and conducted sensitivity analysis and comparative analysis. The analysis results demonstrate that the method possesses strong robustness and effectiveness.
FUCOMSort是一种新的基于共识的多准则排序方法,它利用完全一致性方法(fucomom)将备选方案分类到预定义的类别中。通过减少两两比较,显著提高了分类效率和分类模型的一致性。具体来说,引入了LPHFSs Dombi加权平均算子(LPHFDWA)来有效地聚合专家信息。此外,提出了一种重新定义的混合中心性度量,将信任关系与K-core分解相结合,以评估它们对分类结果的实质性影响。利用信任网络和后悔理论,进一步构建共识过程,解决专家评估中的冲突。FUCOM扩展到lphfs环境,通过线性方程结合主观和客观权重。提出的FUCOMSort方法将两两比较减少到只有n-1,从而大大提高了大规模多准则排序问题的效率。为了验证所提出的方法,我们将其应用于绿色专利价值的分类,并进行了敏感性分析和对比分析。分析结果表明,该方法具有较强的鲁棒性和有效性。

Identifying a specific disease, especially based on common symptoms, can be challenging due to uncertainty and ambiguity, making similarity measures crucial for accurate diagnosis. Therefore, in this article, a novel structure, the similarity measures of a novel mathematical structure called complex picture fuzzy soft sets (cPFSS), is formulated. Firstly, two definitions of similarity measures for cPFSS are established: one based on the membership, non-membership, and neutral functions associated with the set, and the second one based on the distance measures of cPFSS. After that, an algorithm is suggested that is based on the proposed measures between cPFSS, and it is then applied to disease diagnosis. The computational complexity of the proposed algorithm shows that it takes a constant time, even in the case of a large dataset. Additionally, the outcomes show that one patient has the highest similarity with Tuberculosis, while another patient most closely matches Hepatitis.
由于不确定性和模糊性,确定特定疾病,特别是基于常见症状,可能具有挑战性,因此相似性测量对于准确诊断至关重要。因此,本文提出了一种新的结构,即复杂图像模糊软集(cPFSS)的相似度度量。首先,建立了cPFSS相似性度量的两种定义:一种是基于与集合相关的隶属函数、非隶属函数和中立函数,另一种是基于cPFSS的距离度量。在此基础上,提出了一种基于cPFSS间测度的算法,并将其应用于疾病诊断。该算法的计算复杂度表明,即使在大数据集的情况下,它也需要恒定的时间。此外,结果显示,一名患者与结核病最相似,而另一名患者与肝炎最相似。
