Circular dependency calculation

Maybe a short example is better to explain:

- Equip A is incorrect. 
- Equip B is correct but its status depends on the equip A status. 
- Equip C is correct but its status depends on the equip B status. 

So, in a first calculation I can determine a new column of status and the result will be:

- A incorrect 

- B incorrect (because of the dependency with A)

- C correct (because the last known status of equip B is correct)

In a second calculation, the result must be the desired one:

- A incorrect

- B incorrect

- C incorrect

But I have multiple equipments and multiple dependencies. 

thanks!
