Was planned for use in communication with customers for cooperative work on reduction of the bullwhip effect.ĪnyLogic software was utilized by the Supply Chain Innovations team at Infineon.Was used for internal company trainings for bullwhip effect illustration.Helped to analyze particular situations emerging in the market, the consequences of a bullwhip effect, and the amplification of demand along the supply chain.The modelers reproduced the typical behaviors of the agents in a supply chain with the bullwhip effect. Agents under-ordered when careless (-50 % of demand).Agents over-ordered when anxious (+ 20 % of demand).Agents had two states, anxious and careless, determined by inventory reach:.Agents produced generic output (information flow was delayed in the supply chain).
The agents, Infineon, and the market were then all linked together using Discrete Event simulation method to combine a hybrid model with a highly realistic structure.Īll agents outside the semiconductor manufacturer (Infineon) were modeled identically: Base system – a branch where material flowed and orders were executed.Planning and control – a branch where capacity decisions were taken and where forecasts and orders were made.The Infineon agent was separated into two parts: Finally, they recreated a simplified internal structure of Infineon. The modelers used the real GDP and semiconductor market data as input signals. The information and the orders went backwards. Goods were going from the raw material supplier to the semiconductor manufacturer (Infineon), then to the tier 1 and tier 2 suppliers, the OEM (the final manufacturer), and the market. The modelers created agents for each of the major players in the supply chain and gave them behaviors based on the well known "Beer Distribution Game". What connection there is between market demand fluctuation and the fluctuation in demand they received from direct customers.What the bullwhip effect looks like in their supply chain and to what extremes it exists.The Infineon Supply Chain Innovations team wanted to explore the following: The semiconductor industry is very sensitive to outer problems. The demand fluctuates much more at the point of semiconductor production in the supply chain than at the point of the final product. The bullwhip effect refers to a trend of larger and larger swings in inventory in response to changes in demand, as one looks at firms further back in the supply chain for a product. They used AnyLogic software to build a model of a supply chain – from raw materials to the market. The supply chain management at Infineon, a large semiconductor manufacturer, wanted to investigate the bullwhip effect in their market in order to decrease expenses and better forecast market behavior.
