    Abstract [en]

    Route optimization aims to optimize routes for vehicles withregards to resource usage. Especially when the vehicle needsto visit multiple customers on the route, a route optimizationtool is beneficiary. The purpose of this study is to comparehuman experience with a route optimization program. This isdone by comparing how a truck driver makes his routes to theroute a GIS-tool has calculated and then see which of theroutes was shorter, measured in kilometers. The data for thisstudy was gathered from a big shipping company. In order toachieve the purpose of this study 10 routes were analysed bya GIS program called ArcGIS. The algorithm used by ArcGISin route optimization is tabu search, this type of program wasused because it is based on heuristic methods that is muchfaster than exact methods. Expert systems are based onknowledge from experts that have been accumulated duringmany years of experience. Providing recommendations basedon probability reasoning instead of absolute answer. Thesekind of systems is often used in GIS programs to improveresults and calculation time. The aim of this study wasanalyze if a optimization program finds a better route than theexpert. This study shows an improvement of 60% of theanalyzed routes. To verify the results of this study anhypothesis test was made which gave a level of significanceby more than 85 %. The routes were optimized to a certainextent even before the study was done due to the driveralready being familiar with the routes in question. Because ofthis the results of this study were lower compared to othersimilar studies. Another reason may be that the coordinatesgiven to us did not always correspond perfectly with actuallocation of the stops.
