ABSTRACT
Implementing systems engineering in a large-scale driverless rail transit system has never been easy or straightforward. It takes many years of experience working in the design, development, integration and testing to understand how systems engineering can be applied at each stage of the project. With this in mind, we have constructed a generic system-of-systems requirements model derived from our experiences to guide our future rail transit system development.
There are enormous benefits expected from implementing this model at the early stage of the project. Such benefits include establishing the source requirements in line with the contract requirements; identifying full system requirements from the operation concept plan; ease of work assignment and traceability and effective contract interface partitioning. Having an implementable high-level system design before calling tender is essential as it speeds up the system design phase through defining clear system requirement objectives, reuse of mature and best design practices incorporating lessons learned from past projects, and identifying potential areas for improvement for operation and interface issues.
Applying this model will provide a detailed analysis of each requirement breakdown in the areas of operation, system architecture, interface design, safety and other design considerations. Lastly, it also guides the development of configuration management and system testing and commissioning activities that are streamlined with design development in the process of building the project model.
Keywords: Systems engineering, Systems integration, Generic requirements, Reuse, Rail transit system.
