In mathematics and economics often appears the term “small numbers”. The point is that small losses over time begin to turn into significant costs. Add to this, in the case of fleet management, a number of units that generate costs, couse that the total loss can be extremely large. Therefore, for some time in the world, as well as in our large companies that follow global trends, are introduced surveillance systems for the vehicles. Although the starting point was control of the vehicles, over time the systems have developed to the point where they help in the organization of the transport process and generate a number of reports so the person responsible for fleet management has a grat help in planning a better transport process. The beginnings of fleet management are related to the analysis tachograph sheets but today fleet management relyes on information provided by GPS and the computer processing of the collected data. By using computers and the databases are achieved connections between the obtained data. This allows the appearance of new relations among the data which makes programs for fleet management become “living organism” which is is constantly expanding and evolving.
