One Resource Wey Fit Disrupt Other Parts of Life
Trace how failed resource interrupt activities wey depend on am, and compare one backup at a time.
Your numbers
Resources wey the failure affect
Deterministic what-if graph, no be failure probability estimate. Every named dependency must dey available. Loss rates must represent separate losses so you no count the same revenue twice. Backups bypass that resource dependencies with the recovery time wey you enter; each comparison activate only one backup.
Compare scenarios
You fit keep up to three snapshots for this tab. Loading one go replace the present inputs.
Formula
For downstream resource wey failure affect, use dᵢ = max(dⱼ)+rᵢ across im dependencies. d na interruption hours and r na restart delay; di initial failure dey use direct repair time. Backup fit shorten one interruption. Total modeled loss na L = Σ(ℓᵢdᵢ)+B, where ℓ na independent hourly loss and B na cost of di backup wey activate.
Trace how failed resource interrupt activities wey depend on am, and compare one backup at a time.
Example wey show the calculation
- Name of resource wey fail first
- Internet connection
- Resources wey the failure affect
- 3
- Interruption wey last longest
- 11 hours
- Loss if backup no dey
- 940
- Loss plus cost when failed resource get backup
- 270
- Net benefit from backup for failed resource
- 670
Resources and wetin dem depend on

Where e fit work and limits
Deterministic what-if graph, no be failure probability estimate. Every named dependency must dey available. Loss rates must represent separate losses so you no count the same revenue twice. Backups bypass that resource dependencies with the recovery time wey you enter; each comparison activate only one backup.
We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
