Policy and Resilience Calculators

Find 26 calculators for service continuity, backup power, delivery capacity, forecast accuracy, costs and policy review. Each includes a worked example.

Start with a real question

Can a delivery reach people?

Two routes can carry 110 crates a day between them. A shared receiving point can handle only 80. See how that limit leaves 20 of 100 requested crates unmet.

What happens if a shared system fails?

A public service depends on a shared portal. See which functions can continue with a tested local backup and which need more evidence.

Does AI help once people check its work?

Compare staff time and mistakes on the same workload. In the example, AI assistance saves half an hour but produces more audited errors.

Try the human and AI review comparison

The examples are fictional. For your own case, use dated records and state what you are assuming. Compare the current process, a coordinated process run by people, and an AI-assisted process under the same conditions. The tools show practical trade-offs, such as time, cost, errors and service gaps. They do not estimate the chance of war.

Which calculator should I use?

Use the service backlog calculator for queued requests, or service coverage for the share of demand met over time.
Use backup battery runtime for stored energy and power limits, or recovery objectives for verified restoration and data-loss intervals.
Use parallel delivery capacity for shared route limits, or minimum opening stock for scheduled receipts and demand.
Use forecast error to compare supplied predictions against observations, or process cost break-even to compare costs at equal workload.

Start with the fictional inputs, then enter your own. Each calculator shows the formula, units, and limits. Read the policy registry when you have a subject in mind and want to see which tools cover part of it.

Service continuity and capacity

Service Backlog and Clearance Calculator

How many requests remain queued, and when does the backlog clear?

Backup Battery Runtime Calculator

How much of the outage load can a backup battery cover before it reaches reserve?

Recovery Time and Data-Loss Objective Check

Did verified recovery meet the time and data-loss objectives?

Parallel Delivery Capacity Calculator

How much can parallel routes deliver when they share a downstream limit?

Service Coverage and Shortfall Hours Calculator

What share of demand was met, and how long did service fall below its target?

Minimum Opening Stock Calculator

How much stock must be available at the start to cover a declared receipt and demand schedule?

Daily inventory and confirmed receipts

How much demand can the declared stock, confirmed receipts and daily service capacity cover?

Serial service bottleneck

What is the theoretical service ceiling of this serial chain for one common period?

Dependency and tested fallback exercise

Which declared functions remain retained, unavailable or unknown after the supplied outage?

Evidence and measured performance

Forecast Error and Baseline Comparison

How accurate were the supplied forecasts against a baseline on the same observations?

Evidence provenance graph

How many declared traceable origin clusters support these reports, and which origins remain unknown?

Source freshness and comparability

Which records exceed the declared age threshold, have unknown observation dates, or use incomparable periods and units?

Measured manual and AI review workload

How many measured staff-hours and audited errors did each process use on the same workload?

Alert, action and interruption ledger

What false alerts, audited misses, unknown outcomes, ordering delays and measured customer-hours are documented?

Program Evaluation Readiness

Which evaluation-design records are documented, and what descriptive differences can these supplied observations support?

Costs, constraints and trade-offs

Process Cost Break-Even Calculator

At what workloads does the alternative cost the same as or less than the baseline?

Declared fiscal lifecycle ledger

What is the undiscounted and discounted fiscal footprint of the supplied cost ledger?

Budget envelope and restricted balances

Which declared accounts have remaining funds or a funding gap after commitments and proposals?

Declared linear sensitivity exercise

How do declared input ranges change this explicit linear arithmetic result?

Pareto trade-off comparison

Which complete alternatives are no worse on every declared dimension and strictly better on at least one?

Aggregate service coverage differences

What observed coverage differences exist among supplied aggregate groups, and can these groups safely be totaled?

Declared provider concentration

How concentrated is the supplied total, including common parents, and what quantity is retained using only evidenced independent substitutes?
