Wiring it together
Model the relationships that matter.
Connect equipment models into a process. The twin follows the dependencies between assets so a local change can be understood in context.
What you provide, and what you do not
| You | The engine |
|---|---|
| Which machines exist | What has to be calculated first |
| What feeds what | What can run at the same time |
| Which model each machine uses | Following a change through everything downstream |
| The units you work in | Refusing a connection that does not make sense |
§ 01
What it takes care of.
- 01It works out the order for you
You say the pump feeds the pipe and the pipe feeds the tank. Nobody has to write down that the pump must be calculated first — that falls out of the connections.
- 02Independent parts run at the same time
Two lines that do not touch each other are calculated side by side, which is what keeps a large plant inside the time available on a small box.
- 03Connections that cannot be wrong
An output in litres per second will not connect to an input expecting bar. It is refused when you wire it, not discovered as nonsense three weeks later.
- 04Swap a model without stopping
A better model for one machine can replace the old one while everything else keeps running, so improving one part does not mean an outage.
§ 02
Why this is worth having as a proper piece of software.
Plants get modelled in spreadsheets all the time, and it works until the plant changes. Then somebody has to find every cell that assumed the old arrangement, and usually one is missed.
When the connections are described rather than implied, a change is a change to the description. Nothing downstream has to be found by hand, because the engine already knows what depends on what.
Refusing bad connections is the underrated part. Most modelling errors are unit errors, and they are invisible until the answer is wrong by a factor you cannot explain.
“Not the physics. The afternoon somebody added a pump and forgot what it fed.”
What breaks a plant model
Describe one line and watch it resolve.
Sketch a process train on paper the way you would explain it to a new engineer. That sketch is effectively the input, and the working model can be running against your readings the same day.
