For equipment that works very few hours per day, the derived equipment lives may be very long and local conditions should be checked for the reasonableness of the estimate. 3.3.3 Salvage Value (S) This is defined as the price that equipment can be sold for at
A world class example of equipment downtime is anything less than 10%, meaning that a facility's equipment should be running at 90% availability or greater. How to calculate equipment downtime Because this term can apply to any event that halts manufacturing, it's important for an organization to first figure out what kind of downtime they want to calculate.

Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...
All times should be in minutes not hours, with precision down to a tenth of a decimal, for a more granular view of the problem. One can also look at unit ops as VE (value enabling), VA (Value Producing or Value Added) and NVA (no value added, such as a conveyor that simply needs to get product from point A to point B without inducing any quality defects).

Total Down Time = 1.5 hours Since there are 2 failures of 1 and 0.5 hours, overall downtime for this system is 1.5 hours. TOT is calculated using the formula given below TOT = ∑ (Start of Downtime after last Failure – Start of Uptime after last Failure)
On a particular day Machine A recorded downtime of 2 hours (e.g. equipment breakdown, waiting on materials etc..). Scheduled Production Time = 16 Hrs Downtime (planned & unplanned)= 2 Hrs Available Time (Uptime) = 16 Hrs - 2 Hrs = 14 Hrs
