Mapping the Transfer Function
Based on the Risk Decomposition of the Vibration Test, we build the transfer function as following:
Assumption
We simplified the testing scenario that after they fail in the first test and redesign the product, they’ll pass the second test.- The probabilities used to determine if the product passed (95%) or failed (5%) the initial test.- The reliability increases and the liability decreases to approximately 1% of the potential liability cost, compared to 10% for no testing.
For the Test Fail Case:
The redesign cost is added, as well as 10% of the total test cost. Monte Carlo simulations are performed on the test cost, liability cost, and redesign cost.
For the Test Pass Case:
No redesign costs or test cost added.
From the above assumption the transfer function was developed as follows
