The selection of the petrol station for refuel and the amount of refilled fuel are not determined centrally at most transport companies, but depend on the individual decision of the driver, so that the total cost of the burned fuel is not minimal. The goal of this study is to elaborate a precise and reliable mathematical model and method for the determination of the optimal refuel points and the amount of loaded fuel to fulfil specific transport tasks. The model is a mixed valued non-linear programming model, which can be handled by optimization procedures. Based on the elaborated model and method, a decision-supporting software was developed, which provides the required information that is necessary for the economical fulfilment of transport trips.
