El objetivo de este estudio es evaluar herramientas de manufactura esbelta como una estrategia de mitigación de riesgos operacionales en cadenas de suministro del aguacate Hass en el departamento del Valle del Cauca, Colombia. Se usa el mapa de la cadena de valor y se identifican los riesgos. Para priorizarlos, se implementa el Análisis Modal de Efectos y Fallas (AMFE), y el Despliegue de Función Calidad y Lógica Difusa (FQFD). Estos se relacionan con las mudas para proponer herramientas de acciones de mitigación asociadas a herramientas de manufactura esbelta. Los resultados muestran que las 5S (Sort, Set-in-order, Shine, Standardize, Sustain), el Mantenimiento Productivo Total (TPM), el trabajo estándar y la gestión visual respaldan la mitigación de los riesgos en los eslabones estudiados. En conclusión, la cadena productiva está compuesta por productores, transporte primario, línea de empaque y transporte secundario, los cuales son eslabones fundamentales y la fuente principal de riesgos operacionales.

Aplicación de la herramienta Value Stream Mapping a una empresa embaladora de productos de vidrio

Products’ classification according to their importance has been a topic addressed by academia and industry for many years, mainly due to the great importance of this process to obtain efficient inventory policies that reduce lost sales while reducing inventory maintenance costs. This research has to perform an ABC inventory classification in a medium-sized company that sells hardware goods and construction materials, considering multiple quantitative and qualitative criteria. AHP fuzzy TOPSIS multicriteria tool was used as a methodological approach which implies the definition and initial weighting of a set of relevant criteria for the study based on the AHP fuzzy methodology, to obtain an inventory products’ importance assessment according TOPSIS technique procedure. After applying the technique, it is possible to obtain that 0.26% of the inventory was classified as highly critical. Likewise, 5.45% represents products of medium relevance to the organization. Finally, it is observed that many of the products (approximately 94%) have little or almost no impact within the company under study. This methodology was used in a practical case where some criteria were taken from the reviewed literature. In addition, the criticality criterion was used from a financial perspective.

Despite the growing global interest in promoting rural development as a strategy to guarantee food security, in developing countries there are large gaps to achieve a sustainable countryside, mainly in rural areas. This research work delves into a methodological approach definition to establish the baseline for the public policy implementation and prioritize the intervention needs in the different items considered in an integral rural development public policy. The proposed methodology combines a qualitative characterization of needs and goals, a social cartography, a quantitative characterization of indicators and the use of multicriteria classification for prioritizing development policies. Eight localities with sixteen small rural settlements are taken as a research unit, to apply the proposed methodology and determine the implementation level of a public policy. The results show that a set of priority policies that both meet the authorities’ objectives and the population’s needs can be defined. Moreover, a vector of priority is proposed to define the weakest items, as a guide to local government administrations to focus efforts on interventions to achieve greater impacts on the rural community development under study. Finally, via a double field validity assessment, those strategic lines are hierarchized and analyzed regarding their potential relationships, as a social system.
