Opis:
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.

Opis:
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.

Opis:
Atherosclerosis remains the main cause of death worldwide. Most important issues concerning atherosclerosis are hemodynamics and how it affects plaque prevalence and distribution, as well as the symmetry and asymmetry of vasculature and plaques. To present the symmetry in the vascular system an analysis of PubMed and MEDLINE databases was performed. As of February 21, 2023, the results were as follows: for “symmetry” AND “atherosclerosis” there were 47 results; for “symmetry” AND “atherosclerotic lesions” – 20 results; for “symmetry” AND “artery stenosis” – 82 results; for “asymmetry” AND “atherosclerosis” – 87 results. Not without meaning are preventive measures. In the light of the Fourth Industrial Revolution artificial intelligence (AI) solutions help to develop new tools outperforming already existing cardiovascular risk scales. The aim of this paper is to present a current view on symmetry within vasculature and atherosclerosis as well as present a new approach to assess individuals’ cardiovascular risk in accordance with precision medicine assumptions. Symmetry and asymmetry within the human vascular system play a crucial role in understanding of arterial diseases, including atherosclerosis. Moreover, it is unavoidable to use AI in cardiovascular risk stratification.

Opis:
Artificial intelligence (AI) technologies are one of top investment priorities in these days. They are aimed at finding applications in fields of special value for humans, including education. Chatbots are one of those AI-driven solutions that support learning and teaching processes also in higher education institutions. In this paper there are presented two cases of chatbot technology implementation at Polish universities. Chatbots develop students’ technical and programming skills, but also provide the possibility of gaining linguistic expertise. However, a chatbot’s teaching mastery depends also on its users. That is why it is important to get students to truly understand AI systems and feel responsible for the conversation. But above all, we should ensure that chatbots respect human and civil rights.

Opis:
Nowadays, society claim for efficiency and efficiency of managed resources, so, making-decision people look for transparency and good planning practices. In particular case of ports, many variables are involved on it, so Bayesian networks are a useful tool to make an efficient planning because this kind of networks allow to know relationships between variables, even when they are a great number of them. In order to facilitate this work, the following study is carried out in which, through the construction of a Bayesian network, the. Agent can know interesting information about how port variables are connected and can insert possible actions based on utility of their results, even when number of variables is high as occurs in planning and management of port terminals. There are a low number of studies related to this, so, our research includes more than 40 port variables, belonging to the four dimension of port sustainability. Main obtained conclusion shows that economic variables are the network parents in most of cases, so, their consideration is very important in planning decision-making. Their knowledge even allows to estimate probability of the rest of variables including in the network.

Opis:
The first two decades of the 21st century witnessed the emergence of technical and technological solutions that have enabled digital transformations in the global economy. Registration of unstructured data and bringing them together into large datasets have enriched the cognitive process comprising traditional generation of human knowledge and the digital transformation of data into information and then into industrial knowledge. As a result, we obtain augmented knowledge. Yet, robots and bots (i.e., a device which, unlike a robot, is not connected with mechanisms and other peripheral devices) fuelled by technologies collectively referred to as artificial intelligence, primarily by the machine learning technology, are not able to develop wisdom. That is because robots and bots operate only within two dimensions: perception and context, while a human being has his/her autonomous and subjectively defined axiological system, which shapes his/her capacity to make value judgements and generate wisdom. This system is the third dimension in the aquarium with the glass front wall and the remaining three walls carved in stone. It provides stability ensured by a solid foundation of an axiological system that is thousands of years old and has been approved by the entire global community. Subjectivity of value judgements made by individuals and social groups produces a great variety of assessments of available knowledge. That is evidenced, inter alia, by decisions about the use of nuclear energy or decisions regulating free access to personal data and interfering with private life.

Opis:
Sediment is a universal issue that is generated in the river catchment and affects the river flow, reservoir capacity, hydropower generation and dam structure. This paper aims to present the result of experimentation in sediment load estimation using various machine learning algorithms as a powerful AI approach. The data was collected from eight locations in upstream area of Ringlet reservoir catchment. The input variables are discharge and suspended solid. It was found that there is strong correlation between sediment and suspended solid with correlation coefficient of R = 0.9 . The developed ML model successfully estimated the sediment load with competitive results from ANN, Decision Tree, AdaBoost and SVM. The best result was produced by SVM (v-SVM version) where very low RMSE was generated for both training and testing dataset despite its more complicated hyperparameters setup. The results also show a promising application of machine learning for future prediction in hydro-informatic systems.

Opis:
In this paper focus is set on data reliability. We propose a few methods, which calculate credibility coefficients for objects stored in decision tables. Credibility coefficient of object is a measure of its similarity with respect to the rest of the objects in the considered decision table. It can be very useful in detecting either corrupted data or abnormal and distinctive situations. It is assumed that the proper data appear in majority and can be separated from improper data by exploring mutual resemblance. The proposed methods take advantage of well known and widely used data mining technique - rough sets.

Opis:
A fuzzy control system which is a typical system utilizing fuzzy model is mainly using the Max-Min CRI (Compositional Rule of Inference) method by Zadeh and Mamdani for fuzzy inference. But the Max-Min CRI method suffers from drawbacks including: error-prone weighting strategy, inefficient compositional rule of inference, and subjective formulation of membership functions. Because of these problems in the Max-Min CRI method, the inference often results in significant error regions specifying the difference between the desired outputs and the inferred outputs. To overcome such problems, we propose here a new fuzzy inference system for artificial intelligence control.

Vehicles route planning in large transportation companies, where drivers are workers, usually takes place on the basis of experience or intuition of the employees. Because of the cost and environmental protection, it is important to save fuel, thus planning routes in an optimal way. In this article an example of the problem is presented solving delivery vans route planning taking into account the distance and travel time within the constraints of vehicle capacities, restrictions on working time of drivers and having varying degrees of movement. An artificial immune system was used for the calculations.
Planowanie tras samochodów dostawczych w dużych firmach transportowych, w których kierowcy są pracownikami najemnymi, najczęściej odbywa się na podstawie doświadczeń lub intuicji pracowników. Ze względu na koszty i na ochronę środowiska ważne jest oszczędzanie paliwa, a więc układanie tras w sposób optymalny. W artykule rozwiązano przykładowy problem planowania trasy samochodów dostawczych ze względu na długość drogi i czas przejazdu przy ograniczeniach ładowności pojazdów, ograniczeniach czasu pracy kierowców i przy uwzględnieniu zmiennego natężenia ruchu. W obliczeniach zastosowano sztuczny system immunologiczny.

Opis:
The paper presents skeleton rule-based expert system of a new generation, named EXPERT 3.0, worked out and programmed by the Author. Notion of a new generation refers here to implementation of a knowledge base of the system in a form of a computer database; previous skeleton expert systems implemented knowledge bases as text files. At first, a theory of expert systems, as one of the branches of Artificial Intelligence, is briefly presented. Then the Author’s original algorithms of the system are described in the paper. Using the EXPERT 3.0 system, execution of the inference processes: forward, backwards or mixed, as well as of falsification of the main hypothesis, is possible. The EXPERT 3.0 system may be loaded with any number of parallel knowledge bases from such domains as technical, medical or financial diagnostics, as well as providing equipment, forecast and many other systems; in the paper, the inference process is illustrated by an example of the diagnostics of the damage to a MKM33 coal mill, working in a 200 MW power unit. Finally, conclusions and recommendations are formulated in the paper.

Opis:
The smart grid concept is predicated upon the pervasive use of advanced digital communication, information techniques, and artificial intelligence for the current power system, to be more characteristics of the real-time monitoring and controlling of the supply/demand. Microgrids are modern types of power systems used for distributed energy resource (DER) integration. However, the microgrid energy management, the control, and protection of microgrid components (energy sources, loads, and local storage units) is an important challenge. In this paper, the distributed energy management algorithm and control strategy of a smart microgrid is proposed using an intelligent multi-agent system (MAS) approach to achieve multiple objectives in real-time. The MAS proposed is developed with co-simulation tools, which the microgrid model, simulated using MATLAB/Simulink, and the MAS algorithm implemented in JADE through a middleware MACSimJX. The main study is to develop a new approach, able to communicate a multi-task environment such as MAS inside the S-function block of Simulink, to achieve the optimal energy management objectives.

Waste collection problems are one of the most important logistic tasks to solve. The paper deals with the optimization of vehicle routes, which is one of the ways of reducing costs of waste collection. In this paper it was formulated the problem of optimization for a single vehicle. This task can be reduced to the Euler’s problem in the mathematical sense. The task was resolved using artificial immune systems. The methods have been adapted to solve real problems of selective waste collection on a small settlement. The solutions were discussed. It was described further plans for the development of methods for waste collection needs.
Problem zbiórki odpadów jest jednym z najważniejszych logistycznych zadań. Celem artykułu jest optymalizacja tras pojazdów odbierających odpady, która jest jednym ze sposobów redukcji kosztów ich zbiórki. W artykule sformułowano kwestię optymalizacji trasy pojedynczego samochodu. Przedstawiony problem może być zredukowany w sensie matematycznym do zadania Eulera. Problem został rozwiązany metodą sztucznych systemów. Metody zostały zaadaptowane do potrzeb rozwiązania rzeczywistego problemu selektywnej zbiórki odpadów na małym osiedlu. Otrzymane wyniki przeanalizowano. Przedstawiono dalsze plany rozwoju metody na potrzeby selektywnej zbiórki odpadów.
