A manufacturing shop processes sheet metal jobs, wherein each job must pass through two machines (M1 and M2, in that order). The processing time (in hours) for these jobs is: Machine Jobs P Q R S T U M1 15 32 8 27 11 16 M2 6 19 13 20 14 7 The optimal make-span (in hours) of the shop is:
A moving average system is used for forecasting weekly demand. F1(t) and F2(t) are sequences of forecasts with parameters m1 and m2, respectively, where m1 and m2 (m1 > m2) denote the numbers of weeks over which the moving averages are taken. The actual demand shows a step increase from d1 to d2 at a certain time. Subsequently,
