Abstract
La investigación realizada en el contexto de la logística, muestra que las ciudades actuales mantienen una inmensa actividad comercial debido a la demanda de la población, por satisfacer sus distintas necesidades básicas. La demanda trae consecuencias positivas pues al incrementarse el flujo comercial trae desarrollo generando fuentes de empleo; sin embargo no tomar decisiones oportunas traería consecuencias negativas afectando la salud de los ciudadanos, por ello constituye un desafío para las autoridades ya que mantener la sustentabilidad es importante. Viabilizar la red logística para un óptimo abastecimiento de productos y la colecta de restos generados, fue posible mediante el desarrollo de un modelo de programación entera binaria y una metaheurística llamada GRASP, basado en ruteo de vehículos con ventanas de tiempo. Los resultados obtenidos con las implementaciones muestran la importancia de la propuesta, la cual puede ser extendida a situaciones reales sin necesidad de grandes cambios

The demand brings positive consequences because when the commercial flow increases it brings development generating sources of employment; However, not making timely decisions would bring negative consequences affecting the health of citizens, for this reason it constitutes a challenge for the authorities since maintaining sustainability is important. Making the logistics network viable for an optimal supply of products and the pickup of generated waste, was possible through the development of a binary integer programming model and a metaheuristic called GRASP, based on vehicle routing with time windows. The results obtained with the implementations show the importance of the proposal, which can be extended to real situations without the need for major changes
