Abstract: The purpose of the research is to reduce the logistics costs of a warehouse supplier of products belonging to the primary consumer located in the central area of the State of Veracruz, Mexico. There is an increase in the number of stores to supply due to the quarantine. As a result, its high costs have been negatively affected. Therefore, the project focuses on minimizing the distances travelled in delivering its products, which will reduce costs. From applying vehicle routing with capacity (CVRP), a redesign of delivery routes is carried out weekly, proposing a new weekly delivery schedule of 22 routes and 162 destinations. Whit the CVRP application decreased 23.61% in the distance travelled even with an 8% increase in recipients. Thus, it reflects the fulfilment of the delivery objective to the current stores and those added by the warehouse. The research addresses two problems, first the costs incurred by the warehouse for the delivery of its products. The second is the increase in supply due to the initiative to prevent the spread of the COVID-19 virus, avoid the displacement of long distances to purchase products by the inhabitants and reduce those who attend the stores' Warehouse supplies.
