摘要:

测试新的创新技术是安全和验收的关键任务。但是,如果没有历史真实数据,如何测试新系统?模拟为这个重要问题提供了答案。经典的仿真工具,如基于事件的仿真是公认的。但这些建立的仿真模型大多需要设定许多参数。此外,模拟运行,例如,CFD模拟非常耗时。生成对抗网络(GANs)是为各种任务生成新数据的强大工具。目前,它们最常见的应用领域是图像生成。本文研究了GANs在模拟仿真中的适用性。我们正在比较技术系统的仿真输出与GAN的输出。为了验证这种方法,选择了一个著名的多轿厢电梯系统模拟器。我们的研究证明了这种方法的可行性。它还讨论了在实施过程中出现的陷阱和技术问题。虽然我们能够证明,原则上,GANs可以作为昂贵的模拟运行的替代品,但我们也证明了它们不能“开箱即用”。需要进行微调。我们提出了一个概念验证,这可以作为进一步研究的起点。

英文摘要:

Testing new, innovative technologies is a crucial task for safety and acceptance. But how can new systems be tested if no historical real-world data exist? Simulation provides an answer to this important question. Classical simulation tools such as event-based simulation are well accepted. But most of these established simulation models require the specification of many parameters. Furthermore, simulation runs, e.g., CFD simulations, are very time consuming. Generative Adversarial Networks (GANs) are powerful tools for generating new data for a variety of tasks. Currently, their most frequent application domain is image generation. This article investigates the applicability of GANs for imitating simulations. We are comparing the simulation output of a technical system with the output of a GAN. To exemplify this approach, a well-known multi-car elevator system simulator was chosen. Our study demonstrates the feasibility of this approach. It also discusses pitfalls and technical problems that occurred during the implementation. Although we were able to show that in principle, GANs can be used as substitutes for expensive simulation runs, we also show that they cannot be used "out of the box". Fine tuning is needed. We present a proof-of-concept, which can serve as a starting point for further research.
