This column comes to you from Triangle Towne Center in Raleigh, N.C., where many shoppers appear to be getting a jump on the holidays. For this editor, today’s mall visit is all about fashion, not Santa shopping. My teenage daughter and her best friend, who recently returned after living in London for two years, are checking out winter jackets.
I was curious to hear, in the eyes of a 15-year-old, how shopping in the United States compares to European choices. Not good, I learned.

European retailer Zara is known for delivering hot, edgy fashion—and for fast-paced inventory turns. I recently talked with Professor Jeremie Gallien of the MIT Sloan School of Management about the inventory-optimization models he developed for Zara, in collaboration with professors Felipe Caro, Juan Correa and Jose Antonio Ramos from the UCLA Anderson School of Management and all graduates of the Sloan School. Together they defined mathematical algorithms that would optimize Zara’s replenishment processes.
“Zara replenishes all of its stores two times each week, which creates an enormous amount of decisions to determine every garment and every size that is needed at every store,” reported Gallien.
Replenishment decisions were being made by what Gallien described as “an army of people who spent an entire week doing data entry and very little time thinking about the massive decisions that had to be made or the trade-
