Chapter 7: managing flow variability: safety inventory 7.1 Objective In the previous chapter on inventory‚ we focused on economies of scale as the major driver for inventory. The purpose of this chapter is to introduce the notion of safety inventory as a buffer against stochastic variability in supply / demand and discuss various levers for reducing it. The chapter is covered over two classes each of duration 100 minutes. In the first class‚ we first motivate the need for forecasting as a way
