讲座内容摘要:
Scarf’s max-min order formula for the risk-neutral and ambiguity-averse newsvendor problem is a classical result in the field of inventory management. In this article, we extend Scarf’s formula by deriving an analogous closed-form order formula for the risk and ambiguity-averse newsvendor problem. Specifically, we provide and analyse the newsvendor order quantity that maximizes the worst-case expected profit vs risk tradeoff (risk-averse) when only the mean and standard deviation of the product’s demand distribution are assumed to be known (ambiguity-averse), and the risk is measured by the newsvendor’s profit standard deviation. We provide both analytical and experimental results to illustrate the combined effect of considering risk and ambiguity aversion in computing the newsvendor order.
