Document Summary

Eoq = (2dco/ch) tc = co(d/q) + ch(q/2) Q system: r = d l + z d(l ) P system: q = d (p + l) + z d(p + l) i. Ft+1 = (dt + dt 1 + l + dt (n 1)) / n. Ft+1 = wtdt + wt 1dt 1 + l + wt (n 1)dt (n 1) Aft+1 = ft+1 + tt+1 = [ dt + (1 )ft] + [ (ft+1 ft) + (1 )tt] Ft+1,i = forecast for season i in t+1 = sift+1. Ft+1 = forecast for total demand in t+1. Mean absolute deviation = dt ft / n. Si = seasonal factor for season i = di/ di. Di = actual total past demand for season i. Mean squared error = (dt ft)2 / n. Mean absolute percentage deviation = dt ft / dt. Cumulative avg. demand = (total cumulative demand open. Netting (net requirements) = (gross reqts) (on-hand inventory) (quantity on order)
