Indonesia is widely known as a country with rich biodiversity. Medicinal plants that thrive in Indonesia are utilized as traditional medicine locally known as “jamu”. One of the islands famous for jamu production is Madura Island. As a well-known jamu producer, Madura Island are facing problems related to jamu production. Procurement of medicinal plants is not well controlled. There are no reports of spices procurement and production. When there is an increase in demand or sale of certain jamu, the stock of jamu is commonly inadequate/insufficient This may result in order cancellation. The solution to this problem is to create a production forecasting information system by using single exponential smoothing. The data used is a weekly report on the number of sales of 3 types of jamu from August to October 2024. Mean Absolute Percentage Error (MAPE) testing using an alpha value of 0.1 to 0.9 resulted in “high” accuracy and the forecasted values were close to the actual data values.

The article offers conceptual foundations for formalizing the process of assessing a level of human capital (HC) management at the enterprise using mathematical and computer modeling based on neural network technologies. The methodological approach for assessing the level of human capital management has been improved. This allows the use of neural network tools to identify accurately and reasonably the level of HC management with the help of self-learning multilayer perceptron. The weight coefficients of such a network were calculated. An appropriate artificial neural network – a multilayer perceptron – was built using the mathematical software MatLab and it was successfully diagnosed. The improved mathematical model for assessing the level of HC management at the enterprise makes it possible to display transparently a set of input parameters on a set of output solutions, to decompose such a process, and to simplify the procedure of its formalization. The designed neural network allows us to determine quickly and accurately the level of HC management at the enterprise. The conceptual approach proposed by the authors has several significant advantages over existing alternative methods: accuracy of assessment; taking into account a wide range of various evaluation parameters of impact; high speed of making decisions and self-learning ability. The proposed approach was successfully implemented to assess the level of HC management at 24 domestic enterprises. The information system "HC" developed by the authors allows to calculate the estimated parameters of the evaluation process; to determine the level of HC management based on the mathematical apparatus of the multilayer perceptron. Such estimates correlate with the estimates obtained by the experts of these enterprises which indicates the adequacy of the approach proposed by the authors. Therefore, the proposed information system for assessing the level of management of the HC allows accurate implementation of such a process with minimal time and money costs.

W artykule przedstawiono koncepcyjne podstawy sformalizowania procesu oceny poziomu zarządzania kapitałem ludzkim (HC) w przedsiębiorstwie z wykorzystaniem modelowania matematycznego i komputerowego opartego na technologiach sieci neuronowych. Udoskonalono podejście metodyczne do oceny poziomu zarządzania kapitałem ludzkim. Pozwala to na wykorzystanie narzędzi sieci neuronowych do dokładnej i rozsądnej identyfikacji poziomu zarządzania HC za pomocą samouczącego się perceptronu wielowarstwowego. Obliczono współczynniki wagowe takiej sieci. W programie matematycznym MatLab zbudowano odpowiednią sztuczną sieć neuronową – perceptron wielowarstwowy, która została pomyślnie zdiagnozowana. Udoskonalony model matematyczny oceny poziomu zarządzania HC w przedsiębiorstwie pozwala w przejrzysty sposób przedstawić zbiór parametrów wejściowych na zbiorze rozwiązań wyjściowych, rozłożyć taki proces i uprościć procedurę jego formalizacji. Zaprojektowana sieć neuronowa pozwala szybko i trafnie określić poziom zarządzania HC w przedsiębiorstwie. Podejście koncepcyjne zaproponowane przez autorów ma kilka istotnych zalet w porównaniu z istniejącymi metodami alternatywnymi: dokładność oceny; uwzględnienie szerokiego zakresu różnych parametrów oceny wpływu; duża szybkość podejmowania decyzji i umiejętność samokształcenia. Zaproponowane podejście zostało z sukcesem wdrożone do oceny poziomu zarządzania HC w 24 przedsiębiorstwach krajowych. Opracowany przez autorów system informatyczny „HC” pozwala na obliczenie szacunkowych parametrów procesu oceny; określenie poziomu zarządzania HC w oparciu o aparat matematyczny perceptronu wielowarstwowego. Szacunki te korelują z szacunkami uzyskanymi przez ekspertów tych przedsiębiorstw, co wskazuje na adekwatność podejścia zaproponowanego przez autorów. Dlatego też zaproponowany system informatyczny oceny poziomu zarządzania HC pozwala na dokładną realizację takiego procesu przy minimalnych kosztach czasowych i finansowych.

In this research paper, we examine classes of decision tables that are closed under attribute (column) removal and changing of decisions associated with rows. For decision tables belonging to these closed classes, we investigate lower bounds on the minimum cardinality of reducts. Reducts are minimal sets of attributes that allow us to determine the decision attached to a given row. We assume that the number of rows in the decision tables from the closed class is not limited by a constant. We divide the set of these closed classes into two families. In one family, the minimum cardinality of reducts for decision tables is bounded by standard lower bounds of the forms Ω(log cl(Τ), where cl(Τ) represents the number of decision classes in the table Τ. In the other family, these lower bounds can be significantly tightened to the form Ω(cl(Τ) 1/q) for some natural number q.

In the article, a modification of Formal Model of Risk Analysis FoMRA was proposed. The Modified FoMRA (1) method takes into account the guidelines of ISO/IEC 27001 and ISO/IEC 27005 standards. The applied modification and abstraction by resources and security controls (also called countermeasures) significantly shortened the time of risk weight calculation in comparison with the MEHARI method. An attempt was also made to further reduce the time of risk analysis using agents collecting information and data from various network nodes, from operating systems and devices, and additional agents containing information on reports on security procedures, security services, security management and organizational activities related to the information systems (maintenance, insurance, outsourcing contracts, etc.) and transfer it to the local FoMRA1 database. The obtained results indicate that the proposed method together with agents installed in various nodes enable a quick reaction to the system threats and prevention of their impacts (quasi-real-time security monitoring system).

In a connected and uncertain world, where almost two thirds of the world's population are now online, the integration of digital tools in the social and economic context is becoming a priority and an imposed choice for any organization. As a result, the strategic position of the Information System (IS) in these organizations is necessarily linked to performance. The creation of added value or net benefits through the use of these platforms becomes an ultimate and strategic objective for any organization. This study evaluates the success of the information system (IS) for electronic payment of port fees. From a quantitative approach of a hypothetico-deductive nature and using partial least squares structural equation modeling (PLS-SEM), we found that the success of the IS implies a quality of the electronic payment system, as well as the information produced influences the use and satisfaction of the users and finally these last two findings impact the individual and organizational performance of the organizations. (Net benefits).

Background: The purpose of this study is to create a theoretical framework for analyzing the causal relationship between supply chain management practices and firm performance, in the FMCG sector of Pakistan. A quantitative research approach was adopted, in which a multi-item scale Web-based survey using a structured online questionnaire was utilized to collect the primary data. A total of 232 questionnaires were collected from a sample of Karachi-based FMCG companies in Pakistan. Confirmatory Factor analysis and internal consistency were used to test the reliability and fitness of the measurement model, and structural equation modeling-SEM was employed to test the proposed hypotheses. Empirical findings reveal that there is a significant positive relationship between SCM practices and firm performance. However, the results of the individual-level analysis of SCM practices appear to vary from practice to practice. Of various SCM practices, supplier strategic partnership SSC with the highest beta value (i.e., ß = 0.488; t-value = 32.381; p _ 0.000) was found to have the greatest impact on firm performance, followed by information sharing customer relationship, and finally the outsourcing. This study will guide supervisors with a more in-depth understanding of SCM practices and their potential contribution to firm performance. The findings also encourage managers to place supplier strategic partnerships and information systems on high priority, on both inter-firm and intra-firm relationships, as prerequisites for achieving superior firm performance. The propositions and results of the study provide managers with guidelines about effective management of upstream supply chain networks and awareness of the potential synergies that arise from suppliers and the information system. This article further enriches the literature in an evolving area of supply chain management practices. Two key factors facing supply chain managers and scholars are addressed, and establish their ability to drive firm performance.

Modern integrated information and telecommunication systems are upgraded on a continuous basis. Such systems contain both new and old components. The approaches to developing individual components of access control systems are different in the majority of cases. As a rule, modernization of outdated but efficient systems that have been operating without any failures for long periods of time is economically unfeasible. Such an approach requires that different subsystems function based on shared data. This necessitates the coordination of various access control systems in order to ensure proper information security levels. This article examines how joint functioning of various versions of access control systems deployed in IT and telecommunication spheres may be achieved at the stage of their modernization. Potential ways in which information flows may bypass the security policies of one of the access control systems concerned are determined. The authors discuss traditional access control models. For role-based and thematic access control models, specific hypotheses are formulated to comply with security policies when different versions of access control systems work together. The structure of the model assuming that different versions of access control systems operate jointly has been developed. Based on the model, the necessary and sufficient conditions are determined under which unauthorized information flows are prevented. The security theorem for the joint functioning of different versions of access control systems is presented and proved. The results of the study showed that the methodological basis for coordinating access control models applicable to information and telecommunication systems undergoing modernization consists in observing, separately, the equality of information flows between shared objects in each of the versions of the access control systems. The approaches developed in this article can be extended to combined access control systems.

Soldiers of the Territorial Defense Forces (TDF) (Polish name: Wojska Obrony Terytorialnej - WOT) have been supporting medical services and local government entities in the fight against COVID-19 for over 2 years. During the pandemic period, as the number of cases increased, so did the number of operations carried out by TDF soldiers. The considerations presented in the article are related to the territorial defense forces, and the aim of research is to check, verify, and evaluate the status of involvement of TDF in supporting public administration, sanitation and emergency services in the fight against the Sars-CoV-2 coronavirus pandemic. The research hypothesis was adopted, which assumed that the IT application implemented in the Territorial Defense Forces supporting the activities of the Territorial Defense Forces would enable universal access by entities of the non-military system applying for TDF assistance and would shorten the time needed to provide assistance. The implementation of the above-outlined aims of the article required answers to research questions: To what extent did the "Pomoc WOT" IT platform support the public administration, sanitary and emergency services in the fight against the pandemic? The following empirical research methods were applied: the method of analysis and criticism of the literature of the research subject and statistical methods concerning non-military actors, to which the soldiers of the TDF provided support in the fight against COVID-19. From among theoretical methods, the following were used: analysis, synthesis, and inference methods. Scientific research results. More than 1,000 TDF soldiers are deployed every day to carry out the tasks in the fight against the pandemic, providing support in dozens of hospitals and sanitary stations, vaccination points, as well as blood donation and transfusion centers. "WOT Pomoc" application implemented in the TDF Command was developed to facilitate submission, without physical contact, of support requests for TDF soldiers. Through its use, each of the state's non-military system entities eligible to receive military support has the ability to log into the application and submit a request for support. This eliminated the need for multi-level approval of requests, from the voivode up to the Minister of Defense. Since the launch of the application, all the activities related to submitting requests are done automatically, without the need to perform additional actions, and information about the approval of the request is transferred directly to the appropriate brigade commander of the Territorial Defense Forces.

Semantic checking of railway infrastructure information support data is one of the ways to improve the consistency of information system data and, as a result, increase the safety of train traffic. Existing ontological developments have demonstrated the applicability of description logic for modelling railway transport, but have not paid enough attention to the data resources structure and the railway regulatory support. In this work, the formalization of the tabular presentation of data and the rules of railway transport regulations is carried out using the example of a connection track passport and temporary speed restrictions using ontological means, data wrangling and extraction tools. Ontologies of the various formats data resources and railway station infrastructure, tools for converting and extracting data have been developed. The semantic checking of the compliance of railway information system data with regulatory documents in terms of the connection track passport is carried out on the basis of a multi-level concretization model and integration of ontologies. The mechanisms for implementing the constituent ontologies and their integration are demonstrated by an example. Further research includes ontological checking of natural language normative documents of railway transport.

The theory of rough sets was founded by Zdzisław Pawlak to serve as a framework for data and knowledge exploration. Following Professor Pawlak's seminal paper titled "Rough Sets'' published in 1982 in International Journal of Computer and Information Sciences, it is important to discuss the history, the presence and possible future developments of this theory, as well as its applications. One of the key aspects that lets us use rough sets in practical scenarios is the notion of information system, which in fact comes from even earlier Professor Pawlak's works. Information systems are the means for data and knowledge representation. They constitute the input to rough set mechanisms aimed at computing concept approximations and deriving compacted and interpretable decision models. Accordingly, in this paper we discuss where information systems come from. We claim that in many applications it is not enough to treat a data set - represented as an information system - as a purely mathematical object with no linkage to the data origins. Quite oppositely, in practice we may need to work with information systems more actively, giving ourselves a technical possibility to construct them dynamically, taking into account interaction with physical environments where the data is created.

This paper proposes an approach that is suitable for solving multi-criteria decision-making problems that are characterized by fuzzy (subjective) criteria. A finite set (universe) of alternatives will be expressed as a decision table that represents a fuzzy information system, in which every fuzzy criterion is connected with a set of its linguistic values. We apply subjective preference degrees for linguistic values that should be provided by a decision-maker. To simplify the process of decision-making in big data environments, an additional stage will be introduced that can produce a smaller set of alternatives represented by fuzzy linguistic labels of similarity classes. We select a small set of similarity classes for a final ranking. A measure of compatibility will be defined that should express the accordance of a selected alternative with preferences given for the linguistic values of a particular fuzzy criterion.

In this paper a modification of Mike Cohn's test pyramid is described for adaptation during testing in distributed information processing systems which allows expanding the possibilities of testing and applying the features of such systems. Recommendations for further use of the mechanisms of modified Mike Cohn's pyramid are developed. The method of testing the user interface software of the nodes of a distributed system was improved to differ from the existing techniques by including a mechanism of simulation of its operation to allow testing of individual components of the system interface. It is shown that in comparison with end-to-end testing of user interfaces the advantages of using the mechanisms of user interface test simulators allow reducing the time spent on testing any UI service. The time is reduced by decreasing the number of simultaneous user interface services. With a small number of nodes, end-to-end testing of user interfaces is faster than simulation testing of the same user interfaces. As the number of nodes increases, the time required to test the services of a distributed system by simulation tests becomes shorter than the time required to test the same system by a traditional method.
