Minimizing late deliveries in a truck loading problem

Autor: Alice E. Smith, Alejandro Teran-Somohano, Mario C. Vélez-Gallego

Publikováno v: European Journal of Operational Research. 286:919-928

In this work we address the problem of determining the optimal types of products and their quantities that should be loaded on a fleet of heterogeneous one or two level trucks so that the weighted sum of delivered products is maximized, with the weig

A simulation-optimization heuristic for configuring a selective pallet rack system Heurístico de simulación-optimización para la configuración de un sistema de estantería selectiva simple

Autor: Mario C Vélez Gallego, Diego A Valencia Ramírez, Carlos A Castro Zuluaga

Publikováno v: Ingeniare: Revista Chilena de Ingeniería, Vol 20, Iss 1, Pp 17-24 (2012)

A discrete event simulation-optimization heuristic is presented for configuring a selective pallet rack system. To the rack system under study pallets arrive dynamically over time to be stored for a given period of time. The storage duration, arrival

On the Performance of the Subtour Elimination Constraints Approach for the p -Regions Problem: A Computational Study

Autor: Laura Catalina Echeverri, Mario C. Vélez-Gallego, Juan Carlos Duque

Publikováno v: Geographical Analysis. 50:32-52

The p-regions is a mixed integer programming (MIP) model for the exhaustive clustering of a set of n geographic areas into p spatially contiguous regions while minimizing measures of intraregional heterogeneity. This is an NP-hard problem that requir

Technology Updating Decisions for Improving the Environmental Performance of an Operating Supply Chain: A Multiobjective Optimization Model for the Cement Industry

Autor: Gonzalo Guillén-Gosálbez, Mario C. Vélez-Gallego, Nora Cadavid-Giraldo

Publikováno v: Industrial & Engineering Chemistry Research. 55:12287-12300

The obsolescence and related energy inefficiency of many industrial processes are currently an obstacle in the transition toward a more sustainable manufacturing sector. The objective of this work is to exploit the advantages of technology updating f

Multi-product capacitated facility location problem with general production and building costs

Autor: Alejandro Montoya, Mario C. Vélez-Gallego, Juan G. Villegas

Publikováno v: NETNOMICS: Economic Research and Electronic Networking. 17:47-70

This research introduces the multi-product capacitated facility location problem with general production and building costs (MP-CFLPGC). The MP-CFLPGC extends previous problems found in the literature by including multiple products and general produc

Carbon emissions reduction and financial effects of a cap and tax system on an operating supply chain in the cement sector

Autor: Nora Cadavid-Giraldo, Mario C. Vélez-Gallego, Alexandre Restrepo-Boland

Publikováno v: Journal of Cleaner Production. 275:122583

While the cement industry is perceived as one of the major contributors to climate change, with a 7 % share of total C O 2 emissions, direct taxes on emissions of these gases have been little applied to this productive sector. The present study addre
