This article addresses the optimal choice of transport mode for a specific transport task. Knowing each branch’s
limitations, strengths, and weaknesses facilitates decision-making when identifying them for use in a given
situation. This is of particular importance when transporting oversized loads and heavy pieces. Therefore, this
article aims to propose a new model of the game with nature based on SWOT analyses for transport systems
selection for oversized and heavy loads. Firstly, for this solution, it is necessary to define measures for each
of the four elements of a SWOT analysis (i.e., strengths, weaknesses, opportunities, and threats). Secondly,
these four elements are the states of nature in a defined game with nature. Here, the transport mode builds the
scenarios that are possible to select. The SWOT analysis determines the strategic position, market attractiveness
(MA), and market position (MP) of transport modes. Next, applying very well-known decision-making criteria
in the theory of games with nature makes it possible to create appropriate decision-making models for transport
mode selection. The application of the method is shown in the example of selecting the most competitive modes
of transport for oversized loads.
