Abstract
P. Martorell and colleagues model demand-caused failure and standby degradation — showing how a single weak component’s unavailability propagates through safety-system architecture.
Martorell, P., Martón, I., & Sánchez, A. I. (2017). Reliability Engineering & System Safety, 168, 18–27. DOI
Key findings
- Demand stress — Repeated activation degrades components — failure probability rises with use intensity.
- Series logic — Weakest-link behaviour in redundant architectures when mitigation is incomplete.
- Unavailability model — Combines failure probability, testing, and maintenance — engineering formalism, not personal OS proof.
Limits
Nuclear safety-component domain — personal revenue-chain metaphor is coaching translation only.
Application
When one skill gap voids the whole revenue chain, treat it as series reliability — reinforce the weak node first. See Single point of failure.
