Its aim is to plan the range of engineering activities that will ensure that systems comply with the applicable requirements, from design to implementation.** Our experience of transport projects around the world for over 65 years gives us a unique insight into systems assurance for complex systems. We work with engineers at the design stage to ensure that the overall objectives of RAMS (Reliability, Availability, Maintainability, Safety) are achieved and maintained throughout the lifecycle of a project. The choice of a solid systems assurance procedure at the start of a project has proved its effectiveness in ensuring that the system security validation process runs smoothly, in particular by avoiding late modifications and delivery delays. It is also an essential component of performance improvement, as it ensures that the design meets availability and reliability targets well before the system is deployed. ## OPTIMISING THE SECURITY AND PERFORMANCE OF YOUR SYSTEMS ![](https://www.systra.com/wp-content/uploads/2024/02/hum7370-1024x683.jpg) In terms of safety, for example, it is essential that the lines of communication are clear and traceable, ensuring that movement orders given by the communication and train control systems are transmitted only to the trains concerned. In terms of performance, the operator and maintainer must be sure that the system meets the availability target and that service performance is maintained. ## AN INDEPENDENT, PROGRESSIVE AND GLOBAL APPROACH Our approach is based on international systems assurance standards. We provide independent expertise in RAMS. We support you from the design phase through all the stages of your project, ensuring that the documentation, and in particular the safety files, receive formal approval at each key stage. This progressive approach to assurance means that problems can be identified as early as possible and corrective action taken. We are also certified to provide independent safety assessment in a wide range of areas. As a result, our holistic approach to systems is not limited to RAMS, but also covers human factors (for example, taking into account the needs of central control station (CCS) operators during the design phase) and fire safety. ## Our achievements in images - ![Grand Paris Express (Lines 15, 16, 17 and 18) – France](https://www.systra.com/wp-content/uploads/2020/06/header_grand_paris-express-474x474.jpg) - [ Grand Paris Express (Lines 15, 16, 17 and 18) – France ](https://www.systra.com/en/project/grand-paris-express-lines-15-16-17-and-18/) - ![Dubai Metro – United Arab Emirates](https://www.systra.com/wp-content/uploads/2020/07/13-dubai-474x474.jpg) - [ Dubai Metro – United Arab Emirates ](https://www.systra.com/en/project/dubai-metro-united-arab-emirates/) - ![Paris-Bordeaux High Speed line – France](https://www.systra.com/wp-content/uploads/2020/06/lgv_paris_bordeaux-1-474x474.jpg) - [ Paris-Bordeaux High Speed line – France ](https://www.systra.com/en/project/paris-bordeaux-high-speed-line/) [Discover all our projects](https://www.systra.com/en/group/our-projects/) ![visuel-brochures-marches-webfactory-5](https://www.systra.com/wp-content/uploads/2024/02/visuel-brochures-marches-webfactory-5-1024x683.png) ### See our Booklet⏎ “Autonomous mobility: think beyond the vehicle” With this technical notebook, SYSTRA invites you to think about autonomous mobility from the point of view of transport system engineering as a whole, and reveals the key issues involved in these projects.
