The article analyzes mathematical models for evaluating the effectiveness of systems and processes. A model based on the theory of fuzzy logic for complex stochastic systems with multiple initial indicators is selected and substantiated. The concepts and mathematical apparatus of fuzzy logic are described, on the basis of which an algorithm for the implementation of this model is formed to assess the effec-tiveness of the functioning of public urban passenger transport systems. The obtained algorithm, which reduces the complexity of the data processing and the calculation of effective values, has been implemented in the software developed by the authors of the study.
