本文研究了一种基于系统动力学的多尺度仿真方法，分为微观和宏观模型尺度。在微观模型规模上模拟少量零件，从而通过基于物理的模拟明确地实现每个离散元件的运动。在宏观模型尺度上，基于二维双曲偏微分方程（PDE），实现了对大量零件的物料流的模拟。我们明确地检查了虚拟调试的要求，即一毫秒范围内的强时间确定性计算、鲁棒高效的计算算法和系统动态特性。两种仿真模型都针对真实的传送带进行了验证。
In this paper a multi-scale simulation approach based on system dynamics is investigated that is divided into a microscopic and a macroscopic model scale. On the microscopic model scale small amounts of parts are simulated, whereby the motion of each single discrete element is explicitly realized by means of a physically-based simulation. On the macroscopic model scale, based on a two-dimensional hyperbolic partial differential equation (PDE), a simulation of the material flow with a large amount of parts is realized. We explicitly examine the requirements on the virtual commissioning, which are a strongly time-deterministic computation in the range of one millisecond, robust and efficient computing algorithms and system-dynamic features. Both simulation models are validated against a real conveyor belt.
