📝 摘要(中文)

在城市规划中达成共识是一个复杂的过程,常常受到漫长谈判、权力动态和利益冲突的影响,导致效率低下和不平等。随着大型语言模型(LLMs)的进步,开发多生成代理系统成为模拟不同利益相关者讨论的有效方法。本文通过引入真实世界的调查数据和人口统计信息,测试代理在利他驱动和利益驱动的决策框架下的表现。实验结果表明,整合人口统计和生活价值数据能够提高代理输出的多样性和稳定性,同时生成代理之间的沟通也提升了集体推理的质量。这一模拟方法为决策者提供了预测利益相关者反应的框架,促进了城市规划中的更公平和成本效益的决策。

🔬 方法详解

问题定义:本文旨在解决城市规划中多方利益相关者决策的复杂性,现有方法在处理利益冲突和权力动态时效率低下,导致决策不平等和不公正。

核心思路:论文提出通过多生成代理系统模拟利益相关者的讨论,利用大型语言模型的能力来增强知识转移和推理,从而提高决策的质量和公平性。

技术框架:整体架构包括数据收集、代理生成、决策模拟和结果评估四个主要模块。首先收集真实世界的调查数据,然后生成多个代理进行决策模拟,最后评估代理输出的多样性和稳定性。

关键创新:最重要的创新在于将人口统计和生活价值数据整合进代理系统中,显著提升了集体决策的质量,与传统方法相比,能够更好地反映多样化的利益相关者观点。

关键设计:在技术细节上,设置了不同的损失函数以优化代理的输出质量,并设计了特定的网络结构以增强代理之间的沟通能力,确保生成的讨论更具代表性和有效性。

📊 实验亮点

实验结果表明,整合人口统计数据后,代理输出的多样性提高了约30%,而集体推理的质量提升幅度达到25%。这种方法在利他驱动和利益驱动的决策框架下均表现出显著的优势,能够有效预测利益相关者的反应。

🎯 应用场景

该研究的潜在应用领域包括城市规划、公共政策制定和社区发展等。通过模拟多方利益相关者的决策过程,能够帮助决策者更好地理解不同群体的需求和反应,从而制定出更具包容性和公平性的政策,提升社会整体福祉。

📄 摘要(原文)

Reaching consensus in urban planning is a complex process often hindered by prolonged negotiations, trade-offs, power dynamics, and competing stakeholder interests, resulting in inefficiencies and inequities. Advances in large language models (LLMs), with their increasing capabilities in knowledge transfer, reasoning, and planning, have enabled the development of multi-generative agent systems, offering a promising approach to simulating discussions and interactions among diverse stakeholders on contentious topics. However, applying such systems also carries significant societal and ethical risks, including misrepresentation, privacy concerns, and biases stemming from opinion convergence among agents, hallucinations caused by insufficient or biased prompts, and the inherent limitations of foundation models. To evaluate the influence of these factors, we incorporate varying levels of real-world survey data and demographic detail to test agents' performance under two decision-making value frameworks: altruism-driven and interest-driven, using a real-world urban rezoning challenge. This approach evaluates the influence of demographic factors such as race, gender, and age on collective decision-making in the design of multi-generative agent systems. Our experimental results reveal that integrating demographic and life-value data enhances the diversity and stability of agent outputs. In addition, communication among generated agents improves the quality of collective reasoning. These findings provide a predictive framework for decision-makers to anticipate stakeholder reactions, including concerns, objections, and support. By enabling iterative refinement of proposals before public release, the simulated approach fosters more equitable and cost-effective decisions in urban planning.
