The evaluation of the strategic supply chain configuration is considered one of the strategic logistics decisions, especially in food assistance supply chains focused on generating better nutritional conditions in vulnerable populations. In Colombia, there is a social program called Bienestarina, which aims to promote food and nutritional security in a vulnerable population. Although the government supports the program for improving nutritional support, there are currently inconsistencies in freight flows, lack of coverage in some areas, and delivery delays. Therefore, this work aims to evaluate the current configuration of the supply chain and propose improvements related to the facility location. Such advances would enable the increase in the efficacy of the network and the reduction of malnutrition in the country. For this purpose, a mixed-integer mathematical programming model is presented, which considers the weighted distance criterion for different demand scenarios and supports the location-allocation decision in a social assistance supply chain. The current network configuration was compared with the optimal proposed structure. The comparisons show highly potential improvements in freight flow allocation, suggests several variations in the existing warehouses emplacement, and generates public policy implications to reduce the logistic cost in the system, prioritizing in turn the demand covering.
The food assistance programmes (FAP) has the mission to guarantee minimum nutrition requirements in a vulnerable population. Nevertheless, the small deliveries for a spread population, the social conditions, and the limited technological infrastructure could make it difficult to adequately aid supply. To solve these limitations, this chapter proposes a methodology for the design of traceability systems in FAP which allows increasing supply chain visibility, coordination between deliveries and social conditions, and therefore, possible impacts on public policy implications. A qualitative and quantitative comparison of the conventional frameworks is carried out and contrast with the needs of the programmes studied. Also, new criteria are also added to adapt the design to the technological infrastructure and the socio-demographic conditions of the territory. The methodological proposal is applied to the Bienestarina nutritional programme in Colombia, where the technologies and tools to subsequently design the traceability system are proposed.
El actual contexto de los escenarios globales de defensa ha impulsado el desarrollo de conceptos cómo el de logística focalizada, creado para brindar soporte logístico en ambientes de alta volatilidad e incertidumbre. Dentro de ese marco la logística focalizada requiere de herramientas que permitan agilizar los procesos de toma de decisiones en donde la modelación matemática es útil como herramienta de soporte. En orden a lo anterior, se presenta un modelo que pretende soportar la decisión de localización de una plataforma de cross-docking y asignación de medios de transporte utilizando distancias euclidianas de tal manera que se permita garantizar una distribución ágil desde orígenes de suministro hasta los orígenes de demanda siendo especialmente novedosa la estratégica de solución del mismo.
