En la modelación matemática, planteada desde el enfoque de la teoría de grafos, se conjugan ecuaciones del modelo clásico-determinista con una ecuación que incluye un número difuso. Para resolver el problema se propone un método que combina la técnica heurística del algoritmo de los ahorros o de Clarke &amp; Wright, con el enfoque paramétrico del criterio de Verdegay que soluciona problemas de programación lineal difusa. Tras implementarse como una función en el RStudio, se resuelve un problema real para demostrar que el método obtiene soluciones adecuadas.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT The goal of this paper is solving a vehicle routing problem with fuzzy constraints, particularly the capacity constraints has been represented with fuzzy number. The mathematical model was made as a network flows model that combines classic equations with fuzzy parameters. It is proposed a method based in Verdegay&#8217;s approach for solving fuzzy linear programming problems and Clarke and Wright Savings Algorithm, a classical heuristics. The proposed method is implemented as a function in RStudio software and a real problem is solved with it to show that the obtained method provides a good solution.]]></p></abstract>
