  • Publication number: 20040148212
    Abstract: A method for evaluation of optimality of a master production schedule begins by obtaining a forecasted operation schedule, the master production schedule, and an operation completion time. A master production schedule variance is determined from the master production schedule and the operation completion time. Then, a forecasted operation schedule variance is determined from the forecasted operation schedule and the operation completion time. An optimality index is an indicator of the optimality of the master production schedule, which is determined as a function of the operation schedule variance to the forecasted schedule variance. A penalty for deviation of the operation completion time deviation from the master production schedule may be incorporated into the determination. A third embodiment of the method evaluates the concentration/dispersion of the master production schedule variance and provides a better optimality index for a more concentrated distribution of the planned operation index.
