PRISM, a new forest management decision support system, was developed for United States national forest planning at the same time existing tools were deprecated. PRISM has a friendly graphical user interface to facilitate model development, database management, sensitivity analysis, and data visualization. It integrates SQLITE engine for database storage and exploration. It supports both classic forest planning Model I and II to schedule management activities and achieve multiple management objectives through the lifecycle of a forest plan. Multiple models may be created through the PRISM interface and solved in batch mode for convenient sensitivity analysis. Various options to visualize model outputs are available through the embedded JFREECHART library. The open-source nature of PRISM makes it free to use and allows for long-term software development and collaboration. This paper presents the architecture, core functionality, and selected applications of PRISM in the United States national forest planning.

PRISM 是一种新的森林管理决策支持系统，是为美国国家森林规划开发的，同时弃用了现有工具。PRISM 具有友好的图形用户界面，便于模型开发、数据库管理、敏感性分析和数据可视化。它集成了用于数据库存储和探索的 SQLITE 引擎。它支持经典的森林规划模型 I 和 II 来安排管理活动并通过森林规划的生命周期实现多个管理目标。可以通过 PRISM 界面创建多个模型并以批处理模式求解，以便于进行灵敏度分析。通过嵌入式 JFREECHART 库可以使用各种可视化模型输出的选项。PRISM 的开源特性使其可以免费使用并允许长期的软件开发和协作。本文介绍了 PRISM 在美国国家森林规划中的体系结构、核心功能和选定的应用。
