<jats:title>Fuzzy Interpretation of a Transport System Operation Quality Assessment</jats:title>
<jats:p>The paper deals with issues connected with an assessment of transport systems operation quality. The considerations concern real, systems with an intended set of operations, belonging to socio - technical systems of the type whose operation quality assessment is performed depending on value changes of features describing actions of operators, technical objects operated by them and he impact of he environment. Their assessment and providing them with the required functional and operational quality, both in terms of their operation safety efficiency, reliability and ecology, provides basis for accomplishment of the transport service according to the set requirements. This work presents possibilities of application of elements of fuzzy logic in selected stages of the assessment, on the basis of the developed method and the assessment model. Operation quality has been defined as being expressed by means of numerical values identified features, whereas it should be emphasized, that in some cases their direct identification is a significant problem. In connection with this, there was built a fuzzy assessment model for which the scope of changes of the system analyzed features is covered with fuzzy numbers, whereas, their sharp values account for the model initial data. Then, there was presented a fuzzy representation of values of features determined for the system assessment, their graphic interpretation was presented, along with an example of application of fuzzy logic elements for a municipal transport system assessment.</jats:p>
