Constrained Pricing under Finite Mixtures of Logit
Hoang Giang Pham, Tien Mai
The mixed logit model is a flexible and widely used demand model in pricing and revenue management. However, existing work on mixed-logit pricing largely focuses on unconstrained s…
Joint Binary-Continuous Fractional Programming: Solution Methods and Applications
Hoang Giang Pham, Ngan Ha Duong, Tien Mai +2
In this paper, we investigate a class of non-convex sum-of-ratios programs relevant to decision-making in key areas such as product assortment and pricing, and facility location an…
Constrained Assortment and Price Optimization under Generalized Nested Logit Models
Hoang Giang Pham, Tien Mai
We study assortment and price optimization under the generalized nested logit (GNL) model, one of the most general and flexible modeling frameworks in discrete choice modeling. Des…
On the Estimation of Multinomial Logit and Nested Logit Models: A Conic Optimization Approach
Hoang Giang Pham, Tien Mai, Minh Ha Hoang
In this paper, we revisit parameter estimation for multinomial logit (MNL), nested logit (NL), and tree-nested logit (TNL) models through the framework of convex conic optimization…
Outer Approximation and Super-modular Cuts for Constrained Assortment Optimization under Mixed-Logit Model
Hoang Giang Pham, Tien Mai
In this paper, we study the assortment optimization problem under the mixed-logit customer choice model. While assortment optimization has been a major topic in revenue management…
