Single product. Cycle inventory = Q/2 Average flow time = (average inventory)/(average demand) Holding cost H = hC Annual material cost = CD Annual order cost = (D/Q)S Annual holding cost = (Q/2)H Optimal lot size Q* = SQRT((2DS)/H) Optimal order frequency n* = D/Q* = SQRT((DH)/2S) Order cost given a desired lot size S = (H(Q2))/2D Multiple products ................
