发现具有理想性能的新材料对推动创新至关重要。工业4.0与智能制造通过实时数据整合和自动化生产规划控制,有望在此领域带来变革性进展。然而,仅依赖自动化常因缺乏灵活性而难以应对复杂流程。为充分释放智能制造潜力,需从自动化转向自主系统,突破固定编程限制,动态优化解决方案搜索。现有发现方法通常耗时且成本高,尤其在多属性同时优化时更为显著。本文提出一种贝叶斯多目标序贯决策(BMSDM)框架,可在制造过程中智能选择实验,加速向最优设计的探索。该框架通过贝叶斯优化实现序贯学习,迭代更新代表制造过程的统计模型,作为替代真实实验的代理模型,大幅减少所需实际实验次数。在制造数据集上,与传统实验设计(DoE)及两种多目标优化方法对比,BMSDM在五项评估指标中均表现更优。该方法显著推进了智能自主平台在新材料发现中的应用。
原文摘要 · Abstract (English)
Discovering novel materials with desired properties is essential for driving innovation. Industry 4.0 and smart manufacturing have promised transformative advances in this area through real-time data integration and automated production planning and control. However, the reliance on automation alone has often fallen short, lacking the flexibility needed for complex processes. To fully unlock the potential of smart manufacturing, we must evolve from automation to autonomous systems that go beyond rigid programming and can dynamically optimize the search for solutions. Current discovery approaches are often slow, requiring numerous trials to find optimal combinations, and costly, particularly when optimizing multiple properties simultaneously. This paper proposes a Bayesian multi-objective sequential decision-making (BMSDM) framework that can intelligently select experiments as manufacturing progresses, guiding us toward the discovery of optimal design faster and more efficiently. The framework leverages sequential learning through Bayesian Optimization, which iteratively refines a statistical model representing the underlying manufacturing process. This statistical model acts as a surrogate, allowing for efficient exploration and optimization without requiring numerous real-world experiments. This approach can significantly reduce the time and cost of data collection required by traditional experimental designs. The proposed framework is compared with traditional DoE methods and two other multi-objective optimization methods. Using a manufacturing dataset, we evaluate and compare the performance of these approaches across five evaluation metrics. BMSDM comprehensively outperforms the competing methods in multi-objective decision-making scenarios. Our proposed approach represents a significant leap forward in creating an intelligent autonomous platform capable of novel material discovery.
