Greetings,

I'd like to know in your production equipments, how do you calculate the final stoppage / breakdown time?. Example: There are 5 machines in the production module with capacity: 10 ton/h, 8 ton/h, 10 ton/h, 5 ton/h, 8 ton/h. A specific day occurs a general stoppage, where all equipments have been stoped by this problem. The stoppage time of each equipment was: 5.5 h, 3.4 h, 5.5 h, 8.2 h, 5.9 h. There aren't production lines.

What was the final stoppage time of production module?. Is the largest? (5.9 h). Is the smallest? (3.4 h).

Thanks.

PS. If someone knows bibliography about this, I'll appreciate the references.
