In recent years, agriculture has become an essential activity in Colombia, despite the challenges faced by farmers due to low yields and insufficient resources to improve their main activities, such as irrigation systems, agricultural practices, and industrial machinery. This Hass avocado approach has been addressed in previous research considering system dynamics simulation to evaluate farmers’ behavior strategies and improve their competitiveness. However, these studies typically examine a single strategy effect and avoid multiple integrated strategies. Other studies focused on the complex interactions between different factors in the production chain and their feedback effects on farmers’ productivity and cash flow. For these reasons, this research provides a comprehensively dynamic model and evaluates long-term strategies and their effects on supporting and improving small farmers’ productivity and profitability. A system dynamics methodology was used to model complex systems processing Hass avocado farmer association data and explore their effects on competitiveness for long-term sustainable and profitable agriculture. This research proposes optimal scenarios for small farmers, including strategies such as low-interest credit access, logistics practices, and government technical support. The scenarios provide a proactive tool for decision makers and promote rural farmers’ development, aligning high-quality fresh product supply and demand.
Objective: This research work proposes and evaluates a model for the provision of physical rehabilitation services supported by teleoperated technological aids, using the Internet as a communication channel for the care of the rural population, and by taking as the study region, a western subregion of Colombia around the municipality of Santiago de Cali- Colombia. Methodology: From the dynamics generated by the interaction between the service system and the users, characterized by the occurrence of events, a formal model was built, using a Colored Petri Net. To do this, a modelling methodology based on a top-down approach was proposed. Results: A model of the care system was developed and evaluated using Petri nets, based on a case study consisting of the current care model offered by a typical health service provider in Cali called "La Ladera ESE Health Network". The weighted improvements through the proposed system were: greater objectivity of traceability, speed of communication, better quality of rehabilitation, as well as the ability of the new system to contribute to greater precision in the initial diagnosis and subsequent periodic evaluation of recovery. Conclusions: The proposed protocol based on the model made it possible to attend concurrently and accurately diagnose up to three patients, through the implementation of technological aids to improve diagnostic support and allow a subsequent periodic evaluation of the patient´s recovery.
El presente artículo de investigación propone un Modelo de Dinámica de Sistemas para la Gestión del Emprendimiento del Fondo Emprender, el cual se construyó mediante la caracterización de la cadena de valor del proceso, usando la herramienta SIPOC,(Suppliers,Inputs,Process,Outputs and Costumers). Para la definición del problema, en términos estructurales, también fue aplicada mediante una adaptación del Modelo Causal, con el fin de establecer las interdependencias sistémicas y los ciclos de retroalimentación, posibilitando la construcción del modelo a través de la herramienta VENSIM, (Ventana Systems Inc), que utilizó como base conceptual el Diagrama Forrester. De igual manera se realizó una calibración del mismo con datos reales, y se desarrollaron simulaciones que determinaron los principales atributos y permitieron la caracterización del Modelo de Emprendimiento del Fondo Emprender; la quiebra de las empresas, el tiempo dedicado por los asesores a la evaluación de los proyectos, y, en menor grado, el número de planes de negocios evaluados, toda vez que el paradigma propuesto permitió identificar tanto los puntos críticos como de apalancamiento de un modelo dinámico como es el del emprendimiento, convirtiéndose así en una herramienta importante para su gestión.
Avocado is an important export and consumption product in Colombia, and its economic importance is expected to increase in the coming years. With its vast potential territory for avocado cultivation, the department of Cauca is a crucial area for producing this variety. However, small producers in the region often need more knowledge of the most suitable locations for planting. This study seeks to determine the ideal areas for Hass avocado cultivation in Cauca using geographic information tools and multi-criteria decision analysis, using a set of official data from different governmental entities and the hierarchical analytical process that allows determining the intensity of the interrelation of factors in the cultivation of Hass avocado. The results indicate that the municipalities near the Popayán plateau have the most significant potential for Hass avocado production, using the analytical hierarchy process. Approximately 9.2% of the administrative territory of the region is classified as highly suitable for Hass avocado cultivation, and an additional 14.2% is considered moderately suitable, constituting about 700,000 hectares of arable land. This research provides decision-makers and producers with valuable knowledge to support and improve Hass avocado agriculture in the region by implementing agricultural engineering practices.
