摘要

Whereas concurrent design engineering (CDE) processes show great promise for reducing design time and cost, the implicit management of technical risk raises questions about the reliability of resulting designs. CDE team members (chairs) may not possess the skills to perform risk assessment. The authors propose that a risk analyst be integrated into concurrent design engineering teams to explicitly manage a design objective. The contributions that such an analyst could make in the aerospace industry and the tools and information that would be needed to support real-time analysis are discussed. A terrestrial observer swarm problem illustrates the top-down approach to technical risk assessment during the concurrent design process. The swarm model is analyzed in increasingly adaptable models, starting with an instant dual-redundant system and ending with a discrete-time Markov model of swarm life involving dependent satellite lifetimes and an uncertain number of satellites due to the possibility of failures of launch and dispensing operations.
