三、精读内容（Intensive reading content）

本文构建了一个面向云弹性扩展的多粒度三向决策融合模型，分析了跨时间尺度的自适应决策聚合如何影响资源配置效率和服务质量。通过内生化跨粒度决策，该研究揭示了自适应扩展的内在机制，为在动态云环境中平衡响应性和审慎性提供了理论基础。

This paper constructs a multi-granular, three-way decision fusion model for cloud elastic scaling, analyzing how adaptive decision aggregation across timescales affects resource allocation efficiency and service quality. By internalizing cross-granularity decisions, this research reveals the inherent mechanisms of adaptive scaling and provides a theoretical basis for balancing responsiveness and prudence in dynamic cloud environments.

结果表明，与现有方法相比，所提出的多粒度决策融合策略显著提高了资源效率和服务水平协议的遵守率。该机制的有效性取决于局部和全局决策粒度之间的相互作用：当短期波动保持在自适应阈值范围内，且能够充分捕捉长期趋势时，多粒度融合可实现最优性能。一旦偏差超过阈值，单粒度或基于规则的策略将变得更加适用，这表明弹性自适应策略应该能够动态地响应工作负载的波动性。这一发现解释了当前云管理实践中多种扩展策略并存的情况，并强调了根据工作负载特征校准时间粒度阈值的重要性。

Results show that the proposed multi-granularity decision fusion strategy significantly improves resource efficiency and service level agreement compliance compared to existing approaches. The effectiveness of this mechanism depends on the interplay between local and global decision granularity: multi-granularity fusion achieves optimal performance when short-term fluctuations remain within an adaptive threshold and long-term trends are fully captured. Once deviations exceed a threshold, single-granularity or rule-based strategies become more applicable, suggesting that elastic adaptive strategies should be able to dynamically respond to workload volatility. This finding explains the coexistence of multiple scaling strategies in current cloud management practices and highlights the importance of calibrating temporal granularity thresholds based on workload characteristics.

进一步的分析揭示了多粒度扩展决策背后的协调机制：短期响应能力可在快速变化的工作负载下提高资源利用率，而长期审慎策略则可在持续的需求周期内稳定资源分配。基于注意力机制的聚合机制的集成确保了决策过程的可解释性和自动化，从而加深了对时间依赖性如何影响自适应云扩展性能的理解。

Further analysis reveals the coordination mechanism behind multi-granularity scaling decisions: short-term responsiveness improves resource utilization under rapidly changing workloads, while long-term prudence stabilizes resource allocation over ongoing demand cycles. The integration of an attention-based aggregation mechanism ensures the interpretability and automation of the decision-making process, deepening our understanding of how temporal dependencies influence the performance of adaptive cloud scaling.

未来的研究将内化工作负载波动性，并探索系统如何自主学习最佳时间粒度。扩展将结合能效和成本约束，以分析不同优化目标下的权衡取舍，并将该框架扩展到多云或竞争性资源环境，以检验所提方法的可扩展性和适应性。

Future research will internalize workload volatility and explore how the system can autonomously learn the optimal time granularity. Extensions will incorporate energy efficiency and cost constraints to analyze trade-offs under different optimization objectives, and extend the framework to multi-cloud or competitive resource environments to test the scalability and adaptability of the proposed approach.

四、知识补充（Knowledge supplement）

本研究通过引入一个多粒度三向决策融合框架，将局部和全局自适应统一在一个决策范式中，丰富了云计算弹性资源管理的研究。与传统的反应式或预测式扩展机制不同，该方法明确地模拟了跨时间尺度的层级决策交互，从而弥合了资源分配中短期响应能力与长期稳定性之间的差距。

This study enriches the research on elastic resource management in cloud computing by introducing a multi-granular, three-way decision fusion framework that unifies local and global adaptivity in a single decision-making paradigm. Unlike traditional reactive or predictive scaling mechanisms, this approach explicitly models hierarchical decision interactions across timescales, thereby bridging the gap between short-term responsiveness and long-term stability in resource allocation.

从理论角度来看，本研究将三向决策理论扩展到动态多粒度环境中，在该环境中，分布式决策输出通过多头注意力机制进行聚合，以实现自适应且可解释的扩展。这在粒度计算、三向决策理论和基于注意力机制的自适应学习之间建立了一种新颖的联系，为处理云系统中的时间异质性提供了统一的视角。

From a theoretical perspective, this study extends three-way decision theory to a dynamic multi-granularity setting, where distributed decision outputs are aggregated via a multi-head attention mechanism to achieve adaptive and interpretable scaling. This establishes a novel connection between granular computing, three-way decision theory, and attention-based adaptive learning, providing a unified perspective for handling temporal heterogeneity in cloud systems.

从方法论角度来看，该模型引入了一种灵活的决策融合机制，支持自适应阈值和粒度选择。该机制能够根据工作负载波动性实时学习决策边界，为弹性管理系统提供更智能、更自主的基础。该方法可推广至其他资源控制任务，例如任务调度、能耗优化和跨云协调，这些任务需要多层次的自适应性和可解释性。

From a methodological perspective, this model introduces a flexible decision fusion mechanism that supports adaptive threshold and granularity selection. This mechanism learns decision boundaries in real time based on workload volatility, providing a foundation for smarter and more autonomous elastic management systems. This approach can be extended to other resource control tasks, such as task scheduling, energy optimization, and cross-cloud coordination, which require multiple levels of adaptability and explainability.
