Realtime modeling that includes realtime data is starting to be called digital twinning in various industries. E.g. each car off a line has its specific torques of each bolt traveling along with it as a digital twin. Power plants with sensors on all the equipment trying to predict preventive maintenance is being called digital twinning too.

Is this only applied to 'real time' modelling or is 'near real time' also included? Curious because I used to write software for IIOT predictive analysis (3 years ago?) and I never heard the term 'digital twin.' Curious if it applies to NRT or if this is a different beast.

  Use of the term in searches seems to have picked up quite a bit over the past couple of years, so might not have been in such common use ~3yrs ago: https://trends.google.com/trends/explore?date=today%205-y&q=digital%20twin https://trends.google.com/trends/explore?date=today%205-y&q=...

  I work in a field adjacent to all this. My org used to use the term "real time" to mean anything up to and including near-real time. We've recently switched to calling our work "in time" prediction to clarify that we're not referring to real-time in the RTOS sense. Digital twins are a hot topic in aerospace maintenance right now.

  Digital Twin is essentially a buzzword like Cloud. It can mean whatever you want it to, I’m afraid

    I think I've figured out the IBM-style buzzwords like "mobile productivity cloud", and I'm making good progress on all the ones in SJC airport ads, but the one that's still got me is "digital transformation". Shows up all the time in my promoted tweets. Didn't everyone digitally transform in like the 90s?

You can't just affix the word realtime to everything and expect it to make sense. And of course every car manufactured in the last 30 years used tools with exact torques, no worker is pressing on a drill until it feels just right.

  The exact torque measurement within a tolerance is what's recorded, which is different for each car. Less trivially, the vibrations, driving history, etc can be put on the digital twin.
