    OVERALL EQUIPMENT EFFICIENCY
     
    OEE = Availability * Performance * Quality
    Availability = Planned Production time / Available Time (hr.)
    Quality = Weight of good products / Weight of all products
    Performance = Actual rate of machines per item / Ideal rate of machines per item
    Down time percent = down time / Planned production time
    Planned production time = Quantity of Production (km) / Ideal rate of machines (km/hr)
     
    I understand the application in factories as following:
    ·        Availability that if the machine is available 24 hours daily but the sales can only insure orders that make the machine work 12 hours then Availability = 12/24 = 50%
    ·        Quality : If the weight of daily good products 3000 kg while the weight of all products is 3200 kg then Quality = 3000/3200 = 93.57 %
    ·        Performance : if the ideal productivity of the machine is 500 km/hr while the actual was 300km/hr (because of downtime and / or not using the machine with it’s full capacity) then the performance = 300/500 = 60%
    ·       Then OEE = 50% * 93.57% * 60% = 28%
    Would any body approve different understanding ? and is OEE better to be calculated monthly or daily and for each machine or for all machines in one factory together?
