Estimate remaining useful life

Is it possible make a RUL with someone categorical variables (strings)?

[Walter Roberson]

Fuzzy logic?

[hugo monstans thurler dos santos]

Maybe not. I think that work with Just linear regression datasets.

If you have an exemple with RUL with categorical variables, i m going keep grateful with you.

[Walter Roberson]

What do some example entries look like?

[hugo monstans thurler dos santos]

Subsystem, Item name, observerd failure, root cause. this is some examples about categorical variables dataset of blowout preventer (dataset of petroleum engineering).

Follow below the dataset that i explain to you.

[Walter Roberson]

That dataset cannot be used to predict remaining useful life, as it does not contain any information about how long each item was in successful service before a problem was found.
