Sherwin-Williams procurement team will release (place) an order for pigments to meet the gross requirement over the next 5 weeks as indicated in the inventory status record below. The lead time for pigments is one week. Currently, there are 40K gallons of pigment on hand. Assuming that Sherwin- Williams follows Lot-for-lot method to determine the lot size (i.e., order quantity), when and how much pigment should Sherwin-Williams order? What inventory balance would you project at the end of Week 5?
