Integrated Assessment Models (IAMs) are important tools to analyse cross-sectoral interdependencies and the use of global resources. Most current tools are highly detailed and require expert knowledge and proprietary software to generate scenarios and analyse their insights. In this paper, the complementary Global Least-cost User-friendly CLEWs Open-Source Exploratory (GLUCOSE) model is presented as a highly-aggregated global IAM, open and accessible from source to solver and using the OSeMOSYS tool and the CLEWs framework. The model enables the exploration of policy measures on the future development of the integrated resource system. Thanks to its relatively simple structure, it requires low computational resources allowing for the generation of a large number of scenarios or to quickly conduct preliminary investigations. GLUCOSE is targeted towards education and training purposes by a range of interested parties, from students to stakeholders and decision-makers, to explore possible future pathways towards the sustainable management of global resources.

综合评估模型 (IAM) 是分析跨部门相互依存关系和全球资源使用情况的重要工具。当前的大多数工具都非常详细，需要专业知识和专有软件来生成场景并分析其见解。在本文中，互补的全球最低成本用户友好 CLEWs 开源探索 (GLUCOSE) 模型被呈现为高度聚合的全球 IAM，从源代码到求解器都是开放和可访问的，并使用 OSeMOSYS 工具和 CLEWs 框架。该模型能够探索整合资源系统未来发展的政策措施。由于其结构相对简单，它需要的计算资源较少，可以生成大量场景或快速进行初步调查。
