In this research some considerations are made about the possibility of improving making the transportation management, specifically in operations decisions, like routing vehicles, using simple and well known heuristic methods mentioned in the literature. Using a case study, it is possible to show the benefits of changing an empirical routing method based on implicit knowledge towards an empirical application using fixed routes. In additional, is applied a dynamic routing method: the Clarke and Wright`s Method. Results are compared, and after that are recommended routine and tools development to use this application method, consistent and emphatically, in the company case study operation.
