# Asymmetry and Ambiguity in Newsvendor Models

@article{Natarajan2018AsymmetryAA, title={Asymmetry and Ambiguity in Newsvendor Models}, author={Karthik Natarajan and Melvyn Sim and Joline Uichanco}, journal={Manag. Sci.}, year={2018}, volume={64}, pages={3146-3167} }

A basic assumption of the classical newsvendor model is that the probability distribution of the random demand is known. But in most realistic settings, only partial distribution information is available or reliably estimated. The distributionally robust newsvendor model is often used in this case where the worst-case expected profit is maximized over the set of distributions satisfying the known information, which is usually the mean and covariance of demands. However, covariance does not…

Regret in the Newsvendor Model with Partial Information

- Computer ScienceOper. Res.
- 2008

This paper derives the order quantities that minimize the newsvendor's maximum regret of not acting optimally, which can be extended to a variety of problems that require a robust but not conservative solution.

Newsvendor optimization with limited distribution information

This model tries to minimize the regret that is defined as the ratio of the expected cost based on limited information to that based on complete information, called Relative Expected Value of Distribution (REVD), and shows how to derive an optimal solution to the REVD model.

This work proves the proposed approach is (weakly) consistent under some technical regularity conditions and analytically characterize its rate of convergence, and develops theoretical and numerical results for the ambiguity-averse, repeated newsvendor setting.

A Maximum Entropy Approach to the Newsvendor Problem with Partial Information

This paper considers the newsvendor model under partial information, i.e., where the demand distribution D is partly unknown, and shows that the average performance of the maximum entropy approach is considerably better than either minimax regret or Scarf's rule.

Distributionally robust multi-item newsvendor problems with multimodal demand distributions

- Computer ScienceMath. Program.
- 2015

This work presents a risk-averse multi-dimensional newsvendor model for a class of products whose demands are strongly correlated and subject to fashion trends that are not fully understood at the time when orders are placed and demonstrates that disregarding ambiguity or multimodality can lead to unstable solutions that perform poorly in stress test experiments.

It is shown that there exist demand distributions for which the intuition is misleading, i.e., for which larger variances occur in combination with lower costs.
