Aplicación de métodos multicriterio para el soporte de selección de proveedores en la empresa Provemel Ltda

Hoy en día, la logística comercial requiere decisiones estratégicas que deben estar bien fundamentadas con la mayor cantidad de información posible para lograr las ventajas competitivas que las organizaciones necesitan para tener éxito. La selección de proveedores es una parte indispensable de cualquier estrategia de la organización, ya que proporcionan las materias primas necesarias para que comience el proceso de producción. Provemel Ltda tuvo diferentes problemas en términos de proveedores que les impidieron alcanzar tales ventajas competitivas en el mercado. Durante mucho tiempo, la empresa mantuvo una producción ineficiente porque el proveedor real vende los materiales a un alto costo y no siempre tienen el material disponible. Para generar mejores resultados a lo largo de la cadena de suministro de la empresa ya que se entiende que esto debe ser una armonización de los procesos internos entre el comprador y el proveedor, y mejorar el desempeño de la empresa respaldada en la utilidad, calidad, desempeño, tiempo y servicio de lo mismo. Este trabajo presenta un análisis de proveedores enfocado en la aplicación de dos métodos multicriterios. Uno de estos métodos de multicriterios es AHP Difuso que facilita la toma de decisiones en problemáticas donde se involucran varios criterios, el otro es TOPSIS, que se estructura en un algoritmo que genera mejores alternativas para cada criterio. Además, presenta un modelo de orden de pedido que se adapta a las necesidades de la empresa. A través del análisis y la implementación de estos métodos multicriterios, se propuso una solución para la selección de los proveedores, que permite modelar las preferencias de los especialistas y tomar la mejor decisión.Nowadays, business logistics requires strategic decisions that must be well founded with as much information as possible in order to achieve the competitive advantages that organizations need to succeed in the market. The supplier selection is an indispensable part of any organizations strategy, because they provide the raw materials needed for the production process to start. Provemel Ltda had different problems in terms of suppliers which prevented them to reach such competitive advantages in the market. For a long time, the company maintained an inefficient production because the actual supplier sells the materials at a high cost and they do not always have the material available. In order to generate better results along the supply chain of the company as it is understood that this should be a harmonization of the internal processes between the buyer and the supplier, and improve the performance of the company supported in the utility, quality, performance, time and service of the same. In order to take into account the different criteria considered relevant by the company, in this work is presented a supplier analysis focused on the application of two multicriteria methods selected after a deep bibliographical review. One of these multicriteria method is Fuzzy AHP (Hierarchical Analysis Process) that facilitates the decision making in problematics where several criteria are involved. With the help of an expert committee of the company and the information found in the literature, the criteria to be taken into account in the analysis was selected. With this methodology the criteria and their weight was given. The other method is TOPSIS (Technique for Order Performance by Similarity to Ideal Solution), which is structured in an algorithm in which each possible supplier (previously selected by contacting and asking for a quotation to different companies with the aluminum rod 6063HEX 7/16” T5 X3 m in their portfolio), is evaluated according to the criteria and giving as a result the supplier that better fits to the company needs, according to the criteria previously selected and weighted. Additional to this, given that the company does not follows an specific model of order, a deep analysis was made to determine that the best option for the company was to follow an S,T model of order, reason why this work also propose to the company a way to order, avoiding delays and reducing costs
