挑战
联邦交通管理局 (FTA) 要求现代公交系统在全美范围内提供更高效的服务。目前，美国公共巴士交通当局接受大量补贴以满足运营预算，州和地方补贴每年超过 190 亿美元，联邦补贴每年超过 70 亿美元。面临的挑战是设计和制造一种比现有公交车具有更高燃油经济性、更低排放和更低生命周期成本的新型公交车。 BUSolutions 项目的目标是满足这些要求，并为未来的公共交通提供可持续的解决方案。
关于客户
本案例研究中的客户是联邦运输管理局 (FTA) 和美国公共巴士运输当局。这些当局负责在美国各地提供高效、可靠的公共交通服务。他们得到州和联邦政府的大力补贴，以满足运营预算。 FTA 要求这些当局提高服务效率、减少排放并降低公交车的生命周期成本。 BUSolutions 项目的启动是为了满足这些要求，并为未来的公共交通提供可持续的解决方案。
解决方案
BUSolutions 是政府和行业之间的一项合作项目，旨在展示生产易于维护、高效的城市公交巴士的可行性。项目负责人 Altair ProductDesign 与密歇根州东南部的 Automation Alley 合作，实施了仿真驱动的设计方法。他们广泛使用优化技术和方法来驾驶轻型、节能的车辆。该巴士的铝制框架是通过一系列优化研究来设计的，这些研究有助于根据预定义的负载和已知的制造限制来定义理想的材料布局。对于推进，选择了串联液压混合系统，该系统将存储的液压转换成能量，通过液压马达驱动客车。制动能量被捕获并转换为加压流体，然后重新用于提供加速。该液压系统使车辆的燃油效率显着提高，但仍然能够在不更新交通当局现有基础设施的情况下运行。

Case Study
Integral Plant Maintenance
Mercedes-Benz and his partner GAZ chose Siemens to be its maintenance partner at a new engine plant in Yaroslavl, Russia. The new plant offers a capacity to manufacture diesel engines for the Russian market, for locally produced Sprinter Classic. In addition to engines for the local market, the Yaroslavl plant will also produce spare parts. Mercedes-Benz Russia and his partner needed a service partner in order to ensure the operation of these lines in a maintenance partnership arrangement. The challenges included coordinating the entire maintenance management operation, in particular inspections, corrective and predictive maintenance activities, and the optimizing spare parts management. Siemens developed a customized maintenance solution that includes all electronic and mechanical maintenance activities (Integral Plant Maintenance).

Airport SCADA Systems Improve Service Levels
Modern airports are one of the busiest environments on Earth and rely on process automation equipment to ensure service operators achieve their KPIs. Increasingly airport SCADA systems are being used to control all aspects of the operation and associated facilities. This is because unplanned system downtime can cost dearly, both in terms of reduced revenues and the associated loss of customer satisfaction due to inevitable travel inconvenience and disruption.
