Analyses of case studies are used to evaluate new or existing technologies, measures or strategies with regard to their impact on the overall process. However, data availability is limited and hence, new technologies, measures or strategies can only be tested on a limited number of case studies. Owing to the specific boundary conditions and system properties of each single case study, results can hardly be generalized or transferred to other boundary conditions. virtual infrastructure benchmarking (VIBe) is a software tool which algorithmically generates virtual case studies (VCSs) for urban water systems. System descriptions needed for evaluation are extracted from VIBe whose parameters are based on real world case studies and literature. As a result VIBe writes Input files for water simulation software as EPANET and EPA SWMM. With such input files numerous simulations can be performed and the results can be benchmarked and analysed stochastically at a city scale. In this work the approach of VIBe is applied with parameters according to a section of the Inn valley and therewith 1,000 VCSs are generated and evaluated. A comparison of the VCSs with data of real world case studies shows that the real world case studies fit within the parameter ranges of the VCSs. Consequently, VIBe tackles the problem of limited availability of case study data.
案例研究分析用于评估新的或现有的技术、措施或策略对整体过程的影响。然而，数据的可用性有限，因此，新技术、措施或策略只能在有限数量的案例研究中进行测试。由于每个单独案例研究的特定边界条件和系统特性，结果几乎无法推广或转移到其他边界条件。虚拟基础设施基准测试（VIBe）是一种软件工具，它可以为城市水系统自动生成虚拟案例研究（VCS）。评估所需的系统描述从 VIBe 中提取，其参数基于真实世界的案例研究和文献。因此，VIBe 为水模拟软件 EPANET 和 EPA SWMM 编写输入文件。通过这样的输入文件，可以进行大量的模拟，并在城市规模上对结果进行随机基准测试和分析。在这项工作中，根据因河河谷的一个部分应用了 VIBe 的方法，并生成和评估了 1000 个 VCS。将 VCS 与真实世界案例研究的数据进行比较表明，真实世界案例研究的数据在 VCS 参数范围内。因此，VIBe 解决了案例研究数据有限的问题。
