系统的可靠性评估，特别是其可用性，取决于子系统和组件的功能失调行为和维护策略。铁路系统由于列车和路线的数量而变得庞大，但由于信号和联锁所保证的安全性而变得复杂。我们需要一种方法和工具，能够同时为负责设计、运营和维护的人员提供以最佳成本开发基础设施的关键。本文的目的是展示如何自动生成一个满足所有这些需求的模型，以及如何进行性能分析，以获得生产线容量和维护需求方面的指标。
The dependability assessment of systems and in particular their availability depends on the dysfunctional behaviors and maintenance policies of their subsystems and components. Railway systems are large due to the number of trains and routes but also complex due to the safety assured by the signalization and the interlocking. There is a need of methods and tools which could give, at the same time to people in charge of the design, operation and maintenance, the key to exploit the infrastructure at the best cost. The aim of this paper is to show how it is possible to generate automatically a model which satisfies all these requirements and how to do a performance analysis in order to get metrics in terms of capacity of the line, needs of the maintenance.
