本文阐述了铁路承运人在其最佳成本的方式与检查和维护的问题。通常存在外部压力，要求提高可靠性和可用性，并大幅降低成本。为了克服这个问题，本文提出了一个模型，试图找到最佳的检查间隔。不是所有的维护公司都有与系统的实际可靠性相匹配的检查间隔，并且检查间隔不一定是最佳成本。本研究检索的实际故障和维修数据，并结合这与系统的可用性，以找到最佳的检查间隔的成本。应用优化方法在荷兰的铁路承运人维修公司。
This paper states the problem that railway carriers have with inspections and maintenance in its most cost optimal way. Often there is external pressure to improve reliability and availability and to reduce costs significantly. To overcome this problem this paper suggests a model that tries to find the optimal inspection interval. Not all maintenance companies have their inspection intervals that match with the actual reliability of a system anymore and the inspection intervals are not necessarily at a cost optimum. This research retrieves the actual failure and repair data and combines this together with the availability of a system to find the optimum inspection interval in terms of costs. The application of the optimization approach to a railway carrier maintenance company in the Netherlands is also presented.
