Decomposition methods for mixed-integer nonlinear programming
(UMA Editorial, 2021-11-05)La programación no lineal de enteros mixtos es un campo de optimización importante y desafiante. Este tipo de problemas pueden contener variables continuas e enteras, así como restricciones lineales y no lineales. Esta ... -
Experiments with Active-Set LP Algorithms Allowing Basis Deficiency
Hendrix, Eligius Maria Theodorus; Guerrero-Garcia, Pablo (IOAP-MDPI, 2022-12-23)
n interesting question for linear programming (LP) algorithms is how to deal with solutions in which the number of nonzero variables is less than the number of rows of the matrix in standard form. An approach is that of ... -
Generating order policies by SDP: non-stationary demand and service level constraints
Pauls-Worm, Karin G.J.; Hendrix, Eligius Maria Theodorus (2015-07-06)
Inventory control implies dynamic decision making. Therefore, dynamic programming seems an appropriate approach to look for order policies. For finite horizon planning, the implementation of service level constraints ... -
Heuristics for Longest Edge Selection in Simplicial Branch and Bound
Herrera, Juan F.R.; Casado, Leocadio G.; Hendrix, Eligius Maria Theodorus; García-Fernández, Inmaculada (2015-07-06)
Simplicial partitions are suitable to divide a bounded area in branch and bound. In the iterative re nement process, a popular strategy is to divide simplices by their longest edge, thus avoiding needle-shaped simplices. ... -

Inventory control for a non-stationary demand perishable product: comparing policies and solution methods
Hendrix, Eligius Maria Theodorus; Pauls-Worm, Karin G.J (2018-03-02)
This paper summarizes our findings with respect to order policies for an inventory control problem for a perishable product with a maximum fixed shelf life in a periodic review system, where chance constraints play a role. ... -
Modelling vessel fleet composition for maintenance operations at offshore wind farms
Gutiérrez-Alcoba, Alejandro; García-Fernández, Inmaculada; Ortega López, Gloria; Hendrix, Eligius Maria Theodorus (2018-12-20)
Chartering a vessel fleet to support maintenance operations at offshore wind farms (OWF's) constitutes one of the major costs of maintaining this type of installations. Literature describes deterministic optimization models ... -
On computational procedures for Value Iteration in inventory control
Kortenhorst, Cleo; Ortega, Gloria L; Hendrix, Eligius Maria Theodorus (2019-09-11)
Dynamic programming (DP) is often seen in inventory control to lead to optimal ordering policies. When considering stationary demand, Value Iteration (VI) may be used to derive the best policy. In this paper, our focus is ... -
On multimodality of obnoxious faclity location models
(2016-07-21)Obnoxious single facility location models are models that have the aim to find the best location for an undesired facility. Undesired is usually expressed in relation to the so-called demand points that represent locations ... -
