Abstract
Various organizational structure options are proposed in the application of the given model, taking into account the fact that transport authorities should be designed and dimensioned so as to achieve the rudimentary goals and tasks for fulfillment of which they were established. Each task set before the transport authorities requires a reliable and top-quality performance in all environmental conditions. Since most of the acquired data is characterized by a high degree of imprecision, subjectivity and uncertainty, fuzzy logic was used for displaying these. Fuzzy linguistic descriptors were used for describing the criteria used for evaluating the proposed alternatives. In this way, fuzzy logic enables the exploitation of tolerance that exists in imprecision, uncertainty and partial truth of the acquired research results. The paper presents a model for designing the organizational structure of transport support authorities.
