Library — Critical logistics
When the supply chain is the mission
For some operations a late part or a missed delivery is not a cost. It decides whether the operation happens at all.
01The problem
In most supply chains a disruption costs money. In some, it costs the operation.
Where a single component can take an asset out of service, where a supply route can close without warning, and where demand rises exactly when conditions are hardest, the question stops being how efficiently goods move. It becomes whether the right thing will be in the right place at the moment it is needed.
Operations like these usually run on the same fragmented estate as everyone else — inventory in one system, maintenance in another, transport in a third, supplier status in email. The picture of readiness is assembled by hand, which means it is always slightly out of date and never quite the same twice.
Readiness is not a report. It is the current state of a network, and it changes every hour.
02How it plays out
A remote site runs a small group of heavy assets that the rest of the operation depends on. One of them needs a pump assembly at its next service, eleven days out.
An illustrative sequence, not a customer account.
The signal
The supplier’s confirmed ship date for the assembly slips by a week. In the purchasing system it is one changed field on one order line, and nothing about it looks urgent.
What it means
Theralon follows the change forward. The assembly is single-source, with no stock anywhere else in the network; the service cannot be deferred without taking the asset out of use; and the only route into the site runs through a hub already close to capacity for the next fortnight. Propagation puts the asset out of service from day eleven, with two more on the same service cycle exposed within the month.
What is recommended
Three options are weighed against the whole operation: release an assembly held as a spare at a lower-priority location, bring forward the service on a second asset to free a unit already on site, or pay for a route that avoids the congested hub. Each carries its cost, what it displaces and a stated confidence. The first is preferred, because it is reversible and touches nothing else on the critical path.
What follows
The planner approves the transfer the same morning. The decision, the evidence behind it and the outcome are recorded together, so the next time that supplier slips, the history is already there.
Nothing in this sequence needed new data. Every fact already sat in a system somewhere. What changed is that they were read together, early enough to choose.
On your operation
We'd show you readiness as a live picture.
Terra reads critical spares, lead times, routes and assets together, so the part eleven days out is seen against the route that might close and the asset that depends on it.
- Critical spares against long lead times
- Routes that can close, and what they carry
- Decisions laid out with their evidence, under time pressure

03Where Theralon applies
- 01
Readiness as a live picture
Stock, asset condition, maintenance backlog and inbound supply read together, so availability is known now rather than reconstructed for the next review.
- 02
Critical spares and long lead times
The components whose absence would stop an asset, how long each takes to replace, and where alternative supply exists — surfaced before the shortfall is felt.
- 03
Routes that can close
Which movements depend on a single route, hub or carrier, and what reaches the end of the chain if that dependency fails.
- 04
Surge
What a sudden rise in demand does to stock, transport capacity and maintenance throughput across the whole network, not one location at a time.
- 05
Dependencies below the surface
A requirement followed back through suppliers and sub-suppliers to the single source nobody had written down.
- 06
Decisions under time pressure
Recommendations weighed against the whole operation, each carrying its evidence and a stated confidence — so a fast decision is not a blind one.
04What changes

05Under the hood
Assets, parts, locations, routes, suppliers and movements are held in the Principia as connected objects, so a question such as what depends on this route has a direct answer rather than being a spreadsheet exercise. Propagation carries a disruption forward through timing and buffers; Exposure consolidates it into the few concentrations that genuinely matter. Every organisation’s model is held in strict isolation, and access within it is scoped per person.
Two questions
- Does anything tell you which critical assets will be down for want of one part, and when?
- If a route closed tomorrow, could you see today what would not arrive?
Terra does both. See it on your own operation.
Show us where the operation breaks down. We build around your data, your systems and how you actually operate, at whatever size the operation is. Then compare it with what you run today.
There's no cost while we work with you, for the foreseeable future. You see what the software does on your own operation before it costs you anything.
When it has shown its value there, we agree terms with you, sized to what you run, and nothing becomes a contract until you agree to it.
