Purpose: The conducted research was aimed at constructing a structural and functional model for the interaction of bodies providing aviation safety during crisis management. Design/methodology/approach: The methods of mathematical simulation and the graph theory, the methods comparison and formalization have been applied to study the process of interaction between the bodies assuring aviation safety. Using methods of the linear algebra allowed constructing a mathematical model for the functional structure of the interaction process that contains description of this process by the main methods of interaction. Findings: It has been proved that the interaction process has a certain functional properties that reflect the functional relations between the modes of violator actions, the modes of using the response forces and the modes of interaction. A structural and functional model of interaction in semantic, algebraic forms and in the form of graphs has been created. using typical operations with incidence matrices, the possibility of obtaining the physical interpretation of the simulation results within the introduced algebra of functional structure models has been justified. Research limitations/implications: Discusses interactions between the bodies that assure aviation safety and at the same time, the possibility of a crisis situation is taken into account. Practical implications: The developed models allow reflecting the current state of the functional system and the elements of the process of interaction rather completely. It makes a structural and functional analysis of interaction possible and allows defining the priority directions of its organization, simulating the options and methods of interaction in solving relevant tasks by the bodies that assure aviation safety. Originality/value: That allowed not only describing the formal relations between the methods of interaction and interacting units, between the interacting units and the modes of violator actions, but also considering the influence of the interaction process on the current state of the functional system.

Przepływ informacji, który jest w dzisiejszych czasach niezbędny do działania organizacji na rynku wspomagany powinien być technikami informatycznymi. Wiedza, która jest konieczna do pozyskania na rynku logistyki jest pochodną danych i informacji, którymi dysponuje przedsiębiorstwo logistyczne. Niezbędne jest szybkie zbieranie danych, gromadzenie ich oraz przetwarzanie i analiza nie tylko wewnątrz firmy ale również czerpanie wiedzy z zewnątrz. Pomocne w tym zakresie mogą okazać się metody bazujące na eksploracyjnej analizie danych tekstowych – text mining. Zaprezentowano możliwe przykłady wykorzystania i korzyści płynące z zastosowania metod text miningowych w logistyce. W artykule przedstawiono zagadnienie grupowania towarów/produktów, jako atrybutów, według których dokonuje się porównywania, oceny i grupowania kontrahentów. Dokonano zarówno przeglądu jak i przedstawiono propozycje metod i algorytmów grupowania w katalogu towarów.

Necessary the flow of the information which is in contemporary times to the working of the organization should be helped computer technicians. The knowledge which is essential to gaining over on the field of the logistics is the derivative data and information which the logistic company disposes. He indispensable is fast data setting, collection their and processing and analysis not only inside the firm but also draws knowledge from outside. Helpful in this field can prove methods of the text mining. Introduced the possible examples of exploitation and advantages flowing from the use of methods text mining in the logistics. In the paper introduced the question of clustering goods/ products as the attributes according to which achieved comparing, estimation and clustering contractors. It was achieved both the inspection as and the introduced proposals of methods and the algorithms of clustering in the catalog of goods.
