“Inventory Assortment and Substitution Problems” (Joint work with Feng Chen)

We consider general substitution problem, in which consumers can choose one of N variants. We start with a choice model that ranks the preference of each consumer. The preferences of each of the consumers are not known to the retailer and thus, he/she must assume that the demand for each variant is random. We are able to calculate the retailer’s optimal stocking policy. We show that the role of safety stock is to hedge against the uncertainty in the market size but not the uncertainty in the demand for each of the variants. We then move the describe competition between retailer. Again, we are able to characterize the equilibrium inventory levels and assortments. When competition is considered safety stock may be carried even if market size is known. But, in most practical cases if market size is known but consumer choice is random no safety stock is carried with a very high probability.
