What are the impact of bullwhip effect in supply chain?

Distorted information from one end of a supply chain to the other can lead to tremendous inefficiencies: excessive inventory investment, poor customer service, lost revenues, misguided capacity plans, ineffective transportation, and missed production schedules.

How do you calculate bullwhip effect?

A measure for this bullwhip effect is the variability of upstream demand – measured by the standard deviation of demand relative to mean demand – divided by the variability of downstream demand. A value for this measure greater than one indicates amplified order variability.

What is bullwhip effect PDF?

The bullwhip effect refers to the phenomenon where order variability increases as the orders move upstream in the supply chain. Early econometric evidence of bullwhip is highlighted. Findings from empirical and experimental research are compared with analytical and simulation results.
