It would be extremely difficult to keep the factory from destroying itself.

I work in a medical lab. The company bought a new automated coagulation analyzer. The old machine was shut down (proper shut down procedure) and kept in storage in case it was needed. They should have replaced the wash fluid with water. This procedure isn't documented because nobody expects that kind of machine to just sit unused for a long time. After a few months we needed to start it again (can't remeber why, I think there was a delivery problem with the reagents for the new analyzer). We couldn't. The washing fluid dried and detergents and other chemicals it contained solidified inside the valves, just like it happens with an inkjet printer if left unused. They were all stuck. Repair would have been too expensive and it was scrapped.

I saw this happen with a haematology analyzer too. It was kept as a backup but wasn't need for a few months. I was able to resurrect that one after several hours of repeated washing.

An electrolyte analyzer is even worse. Keep it turned off for only a few hours and the electrodes will need to be replaced.

I don't think any other advanced industrial machine is any different. They can't be just left unused for a while and then expect them to work. It's even more problematic if the shut down procedure isn't done right (exceeding the documented requirements) or not at all.
