People are manually loading the parts into the machine, machine cycles, operators lift parts to next machine, machine cycles, and so on. This condition happens approx. When I cycle time the line in the morning when people are starting work feeling rested, cycle time is fast and output is better. Question: Is there a calculation that I can use to calculate a Fatigue Factor We calculate OEE of the line using the bottle neck cycle time. Should I take an average of the cycle time at the start of the shift VS. Based on your description it would seem that the best way to characterize your process would be to build a regression model with cycle time as the outcome and measurement time as the predictor. That would give you cycle time as a function of elapsed time along with an estimate of the variation you could expect to observe at any time during the day. Your post gives the impression that you only take cycle time measurements at the start and the end of a shift. If true you would want to increase your sampling to something like once every two hours for a given period of time in order to have sufficient data for model building. As I understand your current system of measurement you are measuring the time it takes a given operator to complete one part and that time measurement is the amount of time it takes that operator to complete a 10 step process. If this is the case then the smallest unit of independent measures is a given operator. This means that the cycle-to-cycle time measurements for that operator are not independent events. If the above is true then you will have to use repeated measures regression methods to accurately model cycle time as a function of time of day.
