用类人思维解决运筹优化难题,提升代码准确性和流程透明度。
ORMind: A Cognitive-Inspired End-to-End Reasoning Framework for Operations Research
- 模仿人类认知,端到端将需求转为数学模型与可执行代码
- 在NL4Opt和ComplexOR数据集上分别提升9.5%和14.6%
- 适合需要高可靠性和可解释性的企业级运筹决策场景
运筹学(OR)广泛应用于制造、物流、金融和医疗等关键决策问题,影响实际业务结果。尽管大语言模型(LLMs)在多个领域展现潜力,但其在真实工业运筹问题中的应用仍面临重大挑战。现有工业实践存在两大痛点:一是自我修正仅关注代码语法而非数学正确性,易引发严重错误;二是复杂专家选择导致流程不可预测,降低透明度并增加维护成本,难以满足时效性要求。为此,我们提出ORMind,一种受认知启发的端到端推理框架,通过反事实推理增强优化能力。该方法模拟人类思维,实现从需求到数学模型及可执行求解器代码的系统化转化。目前已在联想AI助手内部测试,计划扩展至企业与消费者客户。实验表明,ORMind在NL4Opt数据集上提升9.5%,在ComplexOR数据集上提升14.6%。
原文摘要 · Abstract (English)
Operations research (OR) is widely deployed to solve critical decision-making problems with complex objectives and constraints, impacting manufacturing, logistics, finance, and healthcare outcomes. While Large Language Models (LLMs) have shown promising results in various domains, their practical application in industry-relevant operations research (OR) problems presents significant challenges and opportunities. Preliminary industrial applications of LLMs for operations research face two critical deployment challenges: 1) Self-correction focuses on code syntax rather than mathematical accuracy, causing costly errors; 2) Complex expert selection creates unpredictable workflows that reduce transparency and increase maintenance costs, making them impractical for time-sensitive business applications. To address these business limitations, we introduce ORMind, a cognitive-inspired framework that enhances optimization through counterfactual reasoning. Our approach emulates human cognition, implementing an end-to-end workflow that systematically transforms requirements into mathematical models and executable solver code. It is currently being tested internally in Lenovo's AI Assistant, with plans to enhance optimization capabilities for both business and consumer customers. Experiments demonstrate that ORMind outperforms existing methods, achieving a 9.5\% improvement on the NL4Opt dataset and a 14.6\% improvement on the ComplexOR dataset.
