裁剪顺序规划(COP)是纺织业的关键挑战,直接影响面料利用率和生产成本。传统基于静态启发式和目录估算的方法难以适应动态生产环境,导致次优解和浪费增加。为此,我们提出一种新型量子启发深度强化学习(QI-DRL)框架,结合长短期记忆(LSTM)网络与奥恩-乌伦贝克(OU)噪声。该混合方法旨在解决量子启发概率表征的优势、LSTM在捕捉序列依赖中的作用,以及OU噪声在平滑探索与加速收敛方面的有效性。经过1000轮训练,系统表现稳健,平均奖励为0.81(±0.03),预测损失稳定下降至0.15(±0.02)。对比分析显示,该方法相比传统方法可实现最高13%的面料成本节约。统计评估表明结果变异性低,收敛稳定。尽管仿真模型存在若干简化假设,这些成果仍凸显了该可扩展、自适应框架在提升制造效率方面的潜力,为未来COP优化创新奠定基础。

原文摘要 · Abstract (English)

Cut order planning (COP) is a critical challenge in the textile industry, directly impacting fabric utilization and production costs. Conventional methods based on static heuristics and catalog-based estimations often struggle to adapt to dynamic production environments, resulting in suboptimal solutions and increased waste. In response, we propose a novel Quantum-Inspired Deep Reinforcement Learning (QI-DRL) framework that integrates Long Short-Term Memory (LSTM) networks with Ornstein-Uhlenbeck noise. This hybrid approach is designed to explicitly address key research questions regarding the benefits of quantum-inspired probabilistic representations, the role of LSTM-based memory in capturing sequential dependencies, and the effectiveness of OU noise in facilitating smooth exploration and faster convergence. Extensive training over 1000 episodes demonstrates robust performance, with an average reward of 0.81 (-+0.03) and a steady decrease in prediction loss to 0.15 (-+0.02). A comparative analysis reveals that the proposed approach achieves fabric cost savings of up to 13% compared to conventional methods. Furthermore, statistical evaluations indicate low variability and stable convergence. Despite the fact that the simulation model makes several simplifying assumptions, these promising results underscore the potential of the scalable and adaptive framework to enhance manufacturing efficiency and pave the way for future innovations in COP optimization.
