Title: Data centric approach for supply chain optimization
Abstract: We are working on the project called "Development of data-based identification of discrete optimization problems". In this talk, two topics are introduced. The first topic is the simultaneous optimization of product configuration and supply chain planning considering customer's participation in product design. The second topic is the learning-based approach for identification of objective function for production scheduling problems.

Paper accepted in European Journal of Operational Research


Our paper "A Branch and Bound Approach for Large Pre-marshalling Problems" has been accepted to the European Journal of Operational Research. The paper was coauthored with Prof. Shunji Tanaka, Consuelo Parreno-Torres, Prof. Ramon Alvarez-Valdes and Prof. Ruben Ruiz. We provide new lower bounds and a specialized branch-and-bound approach for solving the container pre-marshalling problem, an optimization problem found in certain types of container terminals. Our exact approach is extremely fast, providing solutions to even large scale problems in under an hour.
