离散事件物质流模拟工具长期以来一直提供实时3D可视化。此功能允许经验不足的用户分析底层系统。除此之外，可视化不用于与模拟（底层制造）系统交互以改善或控制物料流，特别是在干扰下。本文提出了一个基于仿真的两层框架，旨在通过实时用户沉浸式可视化来控制或改善物料流。第一层通过从基于确定性干扰的大量备选策略中进行选择，使用静态优化来计算物料流。第二层是响应式算法，用于计算概率干扰的解。这两层的结果用于通过可视化与底层系统进行交互。我们表明，所提出的系统能够处理复杂的替代策略，支持3D材料流模拟的交互式分析。
Discrete event material flow simulation tools have long been offering real time 3D visualization. This feature allows less experienced users to analyze the underlying system. Beyond this, visualization is not used to interact with the simulated (underlying manufacturing) system to improve or control the material flow, especially under disturbances. This paper presents a simulation based 2-tier framework, which seeks to control or improve material flow by means of real time user immersive visualization. The first tier uses static optimization to compute the material flow by selecting from a large number of alternative policies based on deterministic disturbances. The second tier is a reactive algorithm which computes solutions for probabilistic disturbances. The results of the two tiers are used for interacting with the underlying system using visualization. We show that the proposed system is able to handle complex alternative policies, which supports interactive analysis of 3D material flow simulations.
