    (2018) Alméciga Álvarez, María Alejandra; Velásquez Osorno, Mateo; López Rivera, Yohana Marcela
    At present, companies must take into account a factor of vital importance to ensure the proper management of their suppliers, which is the procedure of selection and evaluation of the provider. Through this important factor, companies can choose the supplier that best fits their strategic policies, and, therefore, have control over customer satisfaction, reputation and the quality of their product. The objective of this project is to formulate strategies to support and strengthen the supplier selection and evaluation process, which increases the efficiency of the supply area in companies and, consequently, contributes to reinforce the integrated management of all the links in the supply chain. The process of selection and evaluation of suppliers in companies requires the use of tools that provide support and facilitate the process of multicriteria decision making, allowing to increase the efficiency, effectiveness and effectiveness of this process. Therefore, in the present project, the use of the hierarchical analysis process, AHP, was considered, which is a mathematical model that considers a series of criteria on which to base the decision-making that is desired to be carried out, in order to choose one among several alternatives. It is important to highlight that the decision criteria used in the present project were selected under a previous literary review, they made a document that implements the AHP tool for the management of suppliers in companies

    (2018) Jiménez Gaviria, William Alexander; Rentería García, Samir Andrés; López Rivera, Yohana Marcela; Serna Urán, Conrado Augusto
    In the present investigation strategies were proposed to strengthen the fruit sector of the department of Antioquia, taking into account the high losses that are had in the postharvest and therefore in the physical distribution. To solve the problem of losses, a bibliographic analysis was carried out from which a database of criteria already used in projects and articles with the technique of the Hierarchical Analytical Process (AHP) was taken, these criteria were classified for the physical distribution (storage and transport). Using the technique Hierarchical Analytical Process (AHP) with storage and transport criteria, a survey was conducted, which was carried out at the Wholesale Center of Medellin where all the fruits of the surrounding municipalities arrive and these in turn are commercialized. At the end of the surveys it was obtained that for transportation one of the aspects to be more careful is the hygiene, and for the storage to have an adequate control over the temperature. When obtaining these data, it was necessary to carry out the Benchmarking analysis, which was done specifically in countries where fruit-growing powers have been implementing innovation technologies to reduce losses in the criteria thrown by the AHP, contemplating in this way the possibility of bringing said technology to the country and thus empower the fruit sector.

    Revisión: estado de la gestión energética
    (2014) López Rivera, Yohana Marcela; Díaz Bermúdez, Jonathan; Pérez Garcés, Helena
    El presente artículo es una revisión de la literatura existente acerca del desarrollo del concepto de Sistema de Gestión Energética (SGE) y avances en materia de documentación y tecnologías tomando como ejemplo Colombia, España y Chile. En el 2011 se lanzó oficialmente la ISO 50001, lo que hace que el tema recobre importancia y las empresas vean la necesidad de implementar la norma en sus procesos productivos, buscando una reducción en los costos. Para lograr esto es necesario medir la eficiencia energética de los procesos, la cantidad de energía que se consume en la elaboración del producto es considerada un costo de producción y lo que se desperdicia significan gastos de producción, además de una gestión energética eficiente se pueden garantizar productos o servicios que cumplan con políticas de sostenibilidad ambiental, lo que ayuda a la organización a posicionarse competitivamente por encima de otras frente a los exigentes consumidores del mercado globalizado actual.
