Optimización del cronograma de abastecimiento semanal para una cadena de restaurantes en Guayaquil

Abstract

This study addresses the distribution problem of a restaurant chain in the city of Guayaquil. Due to the presence of perishable refrigerated products, replenishment visits must be scheduled in compliance with operational constraints to ensure the maintenance of the cold chain. The objective is to schedule and optimize distribution routes, establishing new delivery frequencies per location and improving efficiency compared to the current supply schedule. The methodology was implemented using a constructive heuristic divided into two phases: assigning customers to visit days and routing for a heterogeneous fleet per day. Computational experiments were conducted by varying parameters such as the number of clusters and maximum number of customers. Solutions were analyzed using selection criteria that represent the company's actual operating context to choose the ideal scenario to compare with the current situation. The selected solution minimizes the number of trips and kilometers traveled per week while meeting operational constraints. Thus, the proposed delivery and route planning methodology offers a replicable and scalable approach for companies with analogous distribution processes.
