System safety as an emergent property in composite systems
2009
2009 IEEE/IFIP International Conference on Dependable Systems & Networks
Correctly specifying requirements for composite systems is essential to system safety. In a distributed development environment, safety requirements must be clearly defined for subsystems. Unfortunately, decomposing non-functional requirements, also known as goals, is not always straightforward. Quantifiable goals, such as cost or performance, may be decomposed by allocating a fixed limit on each component. However, system safety is usually not expressible as a sum of parts. Rather, it is
