The New Science of Retailing

How Analytics Are Transforming the Supply Chain and Improving Performance

Authors Marshall Fisher and Ananth Raman, argue that the time is ripe for “rocket science retailing.” Just as Wall Street was transformed in the 1970’s by the influx of physicists, engineers, and “rocket scientists” with mathematical techniques that allowed the harnessing of vast, complicated transaction data, so too retailing is now ready, and in fact beginning a “rocket science revolution.”

Research Summary

Supply Chain Coordination for Products with Uncertain Demand

Ananth Raman has been investigating supply chain coordination for products with uncertain demand in industries as diverse as apparel, power tools, computers, and footwear. Most recently he has been exploring the role of intermediaries, particularly in supply chains that transcend national boundaries. This research, spurred by the steadily rising costs of mismatched supply and demand, takes on added importance with the continuing proliferation of product models and ever-diminishing product life cycles. Raman has identified a number of operational changes that might enable a firm to better match supply with demand, and has developed tools for quantifying the impact of those changes. His findings have been reported in Harvard Business Review and Operations Research, as well as in a number of industry publications.
