The effectiveness of distribution models in Latin America is constrained by unique structural challenges, such as market heterogeneity, infrastructure deficiencies, and high levels of informality, which invalidate the direct application of logistical paradigms from developed economies. This reality highlights a significant gap in the academical literature: the absence of a holistic evaluation framework that integrates operational metrics with sociocultural and inclusion dimensions, especially for the vital proximity store ("nanostore") channel. In response to this need, the main objective of this study is to propose and develop the Comprehensive Evaluation Framework for Distribution Models in Latin America (MEIMDL). To construct it, a qualitative research approach was undertaken through a narrative review of scientific literature and specialized reports, synthesizing existing knowledge to formulate a robust and contextualized conceptual framework. The result is the MEIMDL, a multidimensional model articulated around five interconnected dimensions: Acceptability (alignment with consumer expectations), Affordability (balance between price and perceived value), Accessibility (physical and logistical product availability), Awareness (effective communication of the value proposition), and Adaptability (flexibility to environmental changes and capacity to integrate sustainable practices). This framework, complemented by contingency theory, allows for a deep and adaptive evaluation. In conclusion, MEIMDL is not merely a measurement tool but a strategic guide that enables companies and policymakers to design and optimize distribution systems that are efficient, profitable, inclusive, and resilient, thereby contributing to the region's sustainable economic and social development.
