Evans", publisher="SAE International", title="Minimum Reasonable Inventory and the Bullwhip Effect in an Automotive Enterprise; A “Foresight Vehicle” Demonstrator", booktitle="SAE Technical Paper", year="2002", month="03", abstract="Demand amplification, or the bullwhip effect, has been identified as contributing to increased uncertainty in the supply chain and hence poor performance in terms of increased costs, protracted lead-times and poor customer service levels. This paper shows the application of a simulation based improvement activity focussing on the ordering decisions within a supply chain. An example of a preliminary business diagnostic and subsequent redesign in a four-tier automotive supply chain is presented including value-volume analysis, variability-volume analysis, part clustering and service level - stocking profiles. Specific improvements of up to 5 to 1 in stock holding are realized for continued customer service levels.", doi="10.4271/2002-01-0461" }
