in the simulator, set the number of days to 365, the number of retailers to 100, the base batch size to 100, the retail order pattern to {30%, 8%, 8%, 8%, 30%, 8%, 8%}, mean daily demand at each retailer to 10, and standard deviation of daily demand at each retailer to 4. This ordering pattern mimics the situation where many retail stores place their orders about the same timein this case 30% on the first day of the week, 30% on the fifth day of the week, and the remainder spread across the other five days. Simulate. What evidence does the simulation provide for or against the presence of a bullwhip effect? If the simulation suggests bullwhip exists, what are the primary causes and how might they be affecting operations?
