Controlling replenishment rule induced bullwhip via good systems design


Demand amplification (or bullwhip as it is now popularly called) is not a new phenomenon. Industry typically has to cope with bullwhip measured not just in terms of the 2:1 amplification in orders which is frequently encountered across a single echelon, but sometimes it is as high as 20:1 across the extended enterprise. In this Chapter we consider how bullwhip due to various Forrester effects may be avoided. This leads to our exploitation of a particular Replenishment Rule already widely used in industry and for which analytical formulae for bullwhip generation and inventory variance have been recently derived.
