Stage 2 and 3 are Walmart local supermarkets, which supports demands at Stage 4, 5 and 6, 7, respectively. Stages 4, 5, 6, and 7 are Walmart neighborhood stores, which you can apply EOQ inventory management policy. 5 3 A) In this setting, how many Echelons will be needed if you want to apply series system approach? (Hint: Remember, the inventory pattern in any single Echelon should follow EOQ.) B) Please also describe composition of stages in each Echelon. C) Select one of your Echelon. Please draw the inventory pattern over time in stages and in the echelon. (You may take arbitrary m value). Question 5. Consider the distribution system below.
