Addressing Aircraft System Development Disconnects


System design is, by nature, a process of decomposition, starting from specifications and resulting in a detailed, multi-discipline design. Systems failures are often the result of disconnects in the process. However, gaps can be closed by moving to model-driven development in a structured, requirements-driven process. By applying a seamless, concurrent development process, engineers are able to move validation and verification earlier into the design cycle, when changes can have positive impacts and real improvements can be made.

This presentation demonstrates a top-down, multi-discipline, concurrent design methodology that provides a structure for managing system complexity and ensuring design success. Models from different domains are integrated at each phase of the design flow, allowing system integration issues to be identified and addressed earlier, and helping to reduce overall program time and costs.
