Constraint relaxation for the Discrete Ordered Median Problem
Luisa I. Martínez-Merino, Diego Ponce, Justo Puerto
This paper compares different exact approaches to solve the Discrete Ordered Median Problem (DOMP). In recent years, DOMP has been formulated using set packing constraints giving r…
Production-Inventory games: a new class of totally balanced combinatorial optimization games
Luis A. Guardiola, Ana Meca, Justo Puerto
In this paper we introduce a new class of cooperative games that arise from production-inventory problems. Several agents have to cover their demand over a finite time horizon and…
Production-inventory games and pmas games: characterizations of the Owen point
Luis A. Guardiola, Ana Meca, Justo Puerto
Production-inventory games were introduced in Guardiola et al. (2007) as a new class of totally balanced combinatorial optimization games. From among all core-allocations, the Owen…
Dynamic Realization Games in Newsvendor Inventory Centralization
M. Dror, Luis A. Guardiola, Ana Meca +1
Consider a set N of n (>1) stores with single-item and single-period nondeterministic demands like in a classic newsvendor setting with holding and penalty costs only. Assume a ris…
Unitary Owen points in cooperative lot-sizing models with backlogging
Luis A. Guardiola, Ana Meca, Justo Puerto
Cooperative lot-sizing models with backlogging and heterogeneous costs are studied in Guardiola et al. (2020). In this model several firms participate in a consortium aiming at sat…
Budget-constrained cut problems
Justo Puerto, José L. Sainz-Pardo
The minimum and maximum cuts of an undirected edge-weighted graph are classic problems in graph theory. While the Min-Cut Problem can be solved in P, the Max-Cut Problem is NP-Comp…
