I might not have emphasized this sufficiently in the post, but the aim is not to achieve near 100% robustness. Instead, the goal is to provide people with a fair chance of survival in a subset of crisis scenarios. This concept is inspired by established systems like Nordic civilian defense against nuclear threats or lifeboats on ships. Neither of these protections guarantees survival for everyone—lifeboats, for instance, are not designed to save lives in every conceivable disaster, such as an airplane crash into shallow water at high speed.
The shelters are similarly intended to offer a reasonable chance of survival under specific catastrophic scenarios, recognizing that perfection is neither feasible nor necessary.
Setting Performance Requirements
Determining the appropriate performance threshold will require ongoing dialogue and input from various stakeholders, including potential users. There are several considerations:
User Expectations: Inhabitants’ wants, needs, and available resources will play a significant role in defining acceptable performance levels.
Justifying the Investment: The level of protection must also justify the effort and resources required to produce and deploy the shelters. For example, a hypothetical 90% survival rate might make this intervention compelling compared to doing nothing. On the other hand, if the expected success rate falls near or below 1%, the intervention is unlikely to garner much support.
My initial intuition is that even if 70% of the units function effectively in a crisis, this would be a success. However, these thresholds should not be set arbitrarily—they should involve input from a wide range of stakeholders, particularly those who might depend on these shelters for survival.
