    Hello AllI had this problem in calculating the OEE for our machines,
    1- the problem is that the shift is 8 hours per day and it doesn’t change for the whole year..
    2- another problem is that the machines are not working for the whole 8 hours per day…
    the solution proposed is to know that planned hours and the calculate the worked hours from planned hours…for example your planned hours for a certain day is 5 hours and the machine only worked for 3 hours and the rest 2 hours are wasted for setup,breakdown of m/c,etc..
    This can help in improving the machine to achieve the number of hours it should work per day…The question will be it a machine was planned to work 5 hours and it didn’t work due to breakdown of a certain kind…will the machine be consider to be 0% available or what????Hope this help and hope that you can help on my questionAbdelaziz
