Analyzing disturbances in Global Supply Chains.

      Аннотация: The topic of this project, as it’s possible to understand from the title “Analyzing disturbances in Global Supply Chains”, is to analyze the main disturbances that can born between the actors of a Global Supply Chain. These disturbances can be grouped all inside a unique word:the Bullwhip effect (or Forrester effect). It’s useful to give a definition of this phenomenon: “The Bullwhip effect is the amplification, oscillation and phase lag of the demand (or orders) from downstream to upstream of the Supply Chain”. This demand variability can cause serious problems between the actors of the supply chain, as an increasing of schedule variability, of cycle times, of working and safety stock, of overall costs and so on. As a consequence customer service and profits can decrease. The first author that began to speak about this problem was Forrester, that with his book “Industrial dynamics” (1958) gave a important contribution for the study of this phenomenon.
