Mathematical formulations and optimization algorithms for solving rich vehicle routing problems.
Publicado 2018“…This variant aims to find a route for which the total cost (transportation plus purchasing costs) and the sum of the customers’s waiting time are simultaneously minimized. A mixed integer bi-objective programming formulation of the problem is presented and tested with CPLEX 12.6 within an ǫ-constraint framework which fails to find non-dominated solutions for instances containing more than 10 nodes. …”

Evaluación de la calidad del agua de tres ríos de la subcuenca del “Río Limón” en el estado de Nuevo León
Publicado 2005“…However none chamical constituent exceeded set standards but concentrations of several constituents (pH, CE, Ca2+, Mg2+ Na1 + CO3 - HCO3 Cl- , SO42-) varied according to time, river and location. The time source of variation was explained by increased discharge which appeared to control the concentration of several chemical constituents by dilution. …”

Poverty dynamics in rural Mexico: What does the future hold?
Publicado 2013“…Additionally, asset accumulation dynamics show that there is low asset mobility and that the level of welfare Mexican rural households are expected to reach in the long run would be above poverty, but still quite low (per capita income equal to 6.35 times the Mexican food poverty line). JEL Classification: I32, O12.…”

Cognitive responsive e-assessment of constructive e-learning
Publicado 2016“…A trained neural net successfully recognized students who integrated course schemata related concepts in their lexicon from those who did not by analyzing recognition times after a course. Thus, an innovative e-assessment was implemented by developing a software system that integrates cognitive reports of mental representation due to learning (constructive assessment) with cognitive reports of automatic recognition processing of course content (reactive assessment). …”
