This article presented the hypothesis that expert systems can extend traditional economic modelling. Before this hypothesis was examined, expert systems were specified and example swere given. Expert systems use a knowledge base, often of the form of “if A, then B” rules. It has been highlighted that expert systems have not as often been applied in economics as in other disciplines, like medicine or business science. A SWOT analysis for the stated hypothesis was conducted. Based on this qualitative analysis, the hypothesis was not rejected. An expert system for supporting inflation forecasts will be built in the nearer future.

W niniejszym artykule postawiono hipotezę, że system ekspercki może rozszerzyć tradycyjne podejście modelowe w ekonomii, a także, że systemy te z powodzeniem możemy zastosować do problemów ekonomicznych. Zanim przetestowano hipotezę przedstawiono przykłady zastosowań systemu eksperckiego oraz wykazano, w jaki sposób korzysta ów system z bazy wiedzy. System ten w wielu przypadkach opiera się na warunku, „jeżeli A to B”. Zaznaczono także, że stosowanie systemu eksperckiego jest nieporównywalnie mniej popularne w ekonomii niż w medycynie czy w praktyce biznesowej. Przeprowadzono analizę SWOT w celu weryfikacji hipotezy. Wyniki analizy jakościowej nie pozwalają odrzucić hipotezy, system ekspercki pozwala zmniejszyć niepewność zmiennych ekonomicznych, gdy tylko dostarczymy jemu rzetelną bazę wiedzy. System ekspercki także pomógłby w prognozowaniu inflacji, dlatego ciekawym rozwinięciem powyższych rozważań byłaby budowa systemu eksperckiego wspomagająca prognozowanie inflacji.

In the recent years, one can observe the increase in the number of malicious software (malware) samples analyzed by the antivirus companies. One explanation is associated with attacker's antivirus systems hider tactic, which modifies hostile programs form, without changing it functionality. In effect, the first step of analysis is associated with the check if a given sample is a new threat or modification of existing. Very often such simple test can be performed automatically by dedicated information system. Paper describes information system, which allows dynamic analysis of malicious sample. Presented system was developed and deployed in the Institute of Computer Science, Warsaw University of Technology. During performed security research concerning ransomware threats system proves its usefulness. Additionally, the system become a knowledge base of known malware recently analyzed by our security team.

The paper presents the concept of an expert system supporting knowledge man-agement. The rule-based expert system (RES) uses original, proprietary solutions: a self-organizing Horn clauses table, which simplifies editing and recording of knowledge bases as well as conversion and deduction expert spreadsheets - combin-ing the possibilities of a spreadsheet (algebraic models) with forward deduction ex-pert system, (logical models). The proposed system can be applied in early warning systems and risk management.

The objective of the paper is to present the issue of safety management during the construction process. Threats in the form of disturbances may occur in the preparatory phase, during the execution of the construction project and also during its operational use. The article presents the concept of applying the methodology based, among others, on Learning Bayesian Networks, Artificial Neural Networks and Support Vector Machine, which can be used for building a system for diagnostic and decision-making support at each stage of the construction process. The use of expert systems when it comes to making choices related to construction issues can bring many benefits to decision-makers, as it reduces the risk of taking a wrong decision, and, thus, increases the construction process safety.

W artykule przedstawiono ogólną budowę systemu ekspertowego oraz sposoby przekazywania wiedzy przez człowieka. Uwagę zwrócono również na rolę nauczyciela, a także na to, jak istotny jest proces uczenia takiego systemu w trakcie późniejszej pracy.

This article presents the general structure of expert system and methods of transmitting human knowledge. Attention is also paid to role of teacher and how important is the learning process of this system during the later work.
