Redundancy, uptime & failure — how systems are designed and measured to keep running.
Chain a feed switch, motor and pump in series and watch component survival probabilities multiply into a fragile mission result.
Run two independent full-capacity server nodes in parallel and see how at-least-one survival beats a single branch.
Install N+1 cooling modules, fail units one at a time and track capacity margin against the mission capacity probability.
Feed a dual-input rack from two complete power trains and compare dual-train survival with a single train.
Run a seeded up/repair event simulation and compare observed uptime with the availability implied by MTBF and MTTR.
Put two redundant pumps behind one shared valve and see how much reliability separate outlet paths recover.
Place an outage and a maintenance window on a timeline and compare availability with and without maintenance in the denominator.
Toggle basic events through AND and OR gates and read the top-event probability and minimal cut sets.
Expose two redundant radio towers to a shared storm and see how a common cause erodes the benefit of redundancy.
Combine early defects, a steady hazard and wear-out, then inspect hazard and survival at any equipment age.
