Re: capacity vs Load analysis

How about a number of average hours in the shift capacity desired of  PDM. 
The example would be the same for any number of workers or less hours  due to 
plant HR break lunch structure of actual employee work time.
 
        1 worker @ 8 hours as the  desired capacity in the PDM facility
 
        1 worker x 8 hours = 40  hours per week
        40 hours per week x 50 work  weeks (Holidays = 2 weeks) = 2000 hours 
per year.
 
        now, back out 1 worker  for 10 days vacation for 80 hours
 
        2000 hours - 80 hours  vacation = 1920 hours over 50 weeks
 
        1920 hours per year / 50  weeks = 38.4 hours per week
 
        38.4 hours per week / 5 =  7.62 hours per shift
 
This pure math only calculation would give you a desired shift for planning  
purposes of 7.62 as an average. Many other shift factors are in play, but the  
DESIRED SHIFT LENGHT in PDM facility may be a help.
