The paper describes the analysis of the application of classic and optimized triangular norms in the hierarchical structure of weighted fuzzy Petri nets on the example of passenger transport logistics. The research is presented in a scheme with several levels of tasks. Each task includes some knowledge sets which were previously given by the experts and set into tables of "Object-property" type. It leads to the creation of a hierarchical structure of weighted fuzzy Petri net model which includes 125 possible combinations of triples of functions for calculation processing. A classic triple of functions (ZtN, GtN, ZsN) is tested and compared with an optimized triple (ZtN, ZtN, LsN). Additional verification methods are applied to confirm the practical usefulness of these triples. These techniques imply the use of additional triples which can be associated with each other along with practically efficient mathematical calculations.

This paper continues the analysis of the application of different triples of t-/s-norms and their results in the weighted fuzzy Petri nets for the subject area of passenger transport logistics. The analysis applies the range of 27 different triples of functions which are located in-between minimal (LtN, LtN, ZsN) and maximal (optimized) (ZtN, ZtN, LsN) triples. It also includes classical triple (ZtN, GtN, ZsN) which is located exactly in the middle of this range and remains a good starting point in the comparison of the achieved results. This paper includes a deeper look on the already achieved numerical values as well as decisions and proposes a new approach which will unleash the full potential of the net and applied triples of functions. The idea includes the conception of application of user's expectation. Therefore, the decision-support system provides the results based not only on the input values which were previously filled by the experts in the corresponding subject area, but also on the expectations which can be either met or rejected in the process of calculation.

This paper presents the analysis of a group of triples of functions which imply different combinations of t-/s-norms in the weighted fuzzy Petri nets. The wFPN model was realized in the system PNeS for the subject area of passenger transport logistics. The experiment describes the realization of 15 different triples of functions associated in the range between a minimal triple (LtN, LtN, ZsN) and a classical one (ZtN, GtN, ZsN). It is expected to achieve a numerical rise of the resulting calculations in accordance to the change of the triples in the range from the minimal to the classical one. Additionally, the analysis of achieved decisions with the change of triples is considered for the given subject area.
