Marriott & Demand Forecasting
A few years back, my friend and I came up with a business case for demand forecasting tool for the retailing industry.
Here is what Mariott does , using the same concept. This model as such was present from 1980s where it was first used in the airlines industry. Look at what James Marriot has done to the concept. Applying an old idea to a totally different context.Hats off to him !
