Purpose Supply chains, as prototypical uncertain systems, are crucial for national security and socioeconomic development. Grey system theory (GST) is an effective tool addressing uncertainties has played a pivotal role in related research within the supply chain domain. This study aims to systematically summarize achievements knowledge structures pertaining GST studies. Current potential hotspots also analyzed. Design/methodology/approach CiteSpace used conduct bibliometric analysis of 1,617 articles sourced from Web Science (WOS). The current state structure field. A strategic diagram incorporating two data indicators, namely, novelty concern, constructed based on keyword clustering identify analyze hotspots. Findings Studies utilizing guide practices have attracted interest scholars 205 institutions across 85 countries regions globally, which earned recognition 183 high-level academic journals. In this field, School Economics Management at Nanjing University Aeronautics Astronautics stands out core institution, with Professor Deng Julong, who founder GST, being most frequently cited scholar. complex equipment drivers challenges management, risk closed-loop operation big era. addition, emerging include digital intelligent logistics technology, sustainable supplier determinants flexibility contracts, strategy, purchase grey prediction demand consumption, forecasting economy efficiency, China-specific issues model construction. Originality/value reveals Previous studies primarily relied subjective judgments, lacked empirical support. constructs provide more objective reliable

ABSTRACT Accurate container throughput forecasting is critical for enhancing port efficiency and ensuring global trade stability, particularly in the face of economic uncertainties, geopolitical tensions, supply chain disruptions. Existing methods often struggle to model nonlinear, nonstationary, noise‐laden characteristics data, creating a clear gap ability provide reliable predictions. To address this, we propose novel hybrid model, VMD‐ISE‐TCNT, designed tackle these challenges. The employs variational mode decomposition (VMD) decompose time series into intrinsic modes, with an improved signal energy (ISE) criterion automating selection optimal numbers. These modes are categorized low‐ high‐frequency components forecasted separately using temporal convolutional networks (TCNs), leveraging their strength capturing multiscale dependencies. Theil UII‐S loss function integrated enhance robustness by prioritizing proportional accuracy reducing outlier sensitivity. Empirical evaluations 24 years data from China's two largest ports—Shanghai Shenzhen—demonstrate superior performance VMD‐ISE‐TCNT compared traditional benchmarks. By addressing frequency‐specific patterns key processes, this provides scalable interpretable solution advancing operations resilience trade.

This study introduces a novel multi-criteria group evaluation approach grounded in the theory of basic uncertain information (BUI) to facilitate selection green recycling suppliers for shared electric bikes. Firstly, comprehensive index system is established, encompassing capacity, environmental sustainability, financial strength, maintenance capabilities, and policy support, provide solid foundation scientific process. Secondly, generalized power weighted average (BUIGPWA) operator proposed aggregate with BUI pairs, some related properties are investigated. Furthermore, information-based best–middle–worst TOPSIS (BUI-BMW-TOPSIS) model incorporating best, middle, worst reference points enhance decision-making accuracy proposed. Ultimately, by integrating BUIGPWA aggregation BUI-BMW-TOPSIS handle decision information, (MCGDM) method constructed evaluate Case analyses comparative demonstrate that compared BUIWA operator, yields more reliable results because its consideration degree support among decision-makers. contrast traditional method, incorporates credibility provided decision-makers, leading trustworthy outcomes. Notably, variations attribute weights significantly impact results. In summary, our methods excel handling complex decisions, boosting rigor reliability, supporting optimization sustainability bike suppliers.
