The economic efficiency of outsourcing of transport and logistics services. Case study of the Polish road transport market

The paper deals with the problem of the economic efficiency of outsourcing of organization of transport processes. It presents the results of the research studies from the literature and also research made with the use of an electronic model of economic benefits of cooperation with an external service provider. The model was developed by the Author of the paper and was used to make simulations of different strategies from the perspective both of a carrier and a transport user. According to the results profitability depends rather on the parameters of a process of delivery of goods – average demand, standard deviation, weight and value of transported commodities than on the costs of transport.
