Decision-making is a process which has accompanied the human being since time immemorial and in various areas of their activity. It should result in making a choice that meets the expectations (conditions) of the decision maker to the greatest extent. Decisions can be made on the basis of information which is not always complete and reliable. Sometimes it may happen that it is incomplete and reliable or complete but unreliable. Then, it concerns ill-structured problems. The purpose of this article is to verify whether ill-structured problems can be solved/supported in a way based on an operating algorithm. In the article, a case study with complete but unreliable information as well as with complete and reliable information was used. Logical decision trees were employed in the study. The result of the study allowed for, among others, establishing that the analysis of an ill-structured problem using logical decision trees consists in performing steps which follow one another in a logical sequence creating thus a sequence of operations, and therefore an operating algorithm, which confirms that solving ill-structured problems can be supported/implemented using an algorithm.

Podejmowanie decyzji stanowi proces, który towarzyszy człowiekowi od zawsze i w różnych obszarach jego działalności. Jego rezultatem powinno być dokonanie wyboru, który w największym stopniu spełnia oczekiwania (warunki) decydenta. Decyzje można podejmować na podstawie informacji, które nie zawsze są pełne i pewne. Czasem może się zdarzyć, że są niepełne i pewne lub pełne, ale niepewne. Wówczas dotyczą one problemów słabo ustrukturalizowanych. Celem niniejszego artykułu jest weryfikacja, czy problemy słabo ustrukturalizowane można rozwiązywać/wspierać ich rozwiązywanie w sposób oparty na algorytmie działań. W artykule wykorzystano analizę przypadku z informacjami pełnymi, ale niepewnymi oraz pełnymi i pewnymi. Posłużono się w niej logicznymi drzewami decyzyjnymi. Jej wynik pozwolił m.in. na stwierdzenie, że analiza problemu słabo ustrukturalizowanego za pomocą logicznych drzew decyzyjnych polega na wykonaniu kroków, które następują po sobie w logicznej kolejności. Tworząc tym samym ciąg czynności, a zatem algorytm działania, co potwierdza, że rozwiązywanie problemów słabo ustrukturalizowanych może być wspierane/realizowane za pomocą algorytmu.

Decision-making in companies is often based on the managers' personal experience. However, their consequences can have an impact on the development of the daily activities. To illustrate the managerial impact of decision-making, the biggest African power utility company based in South Africa will be analyzed. Various data such as annual productivity and energy sales were extracted over 15 years from his annual reports and two artificial neural network techniques named Levenberg-Marquardt and Scaled Conjugate Gradient used to analyze them. It emerged from the results obtained that between 2018 and 2020 the company experienced good growth which could extend until 2025 in the best-case scenario or else will drop again to reach its 2020 well-being state. Thus, the obtained results could be used to reinforce the decision-making and to determine the moment when decisions should be taken to prevent the demise of the company.

Podejmowanie decyzji w firmach często opiera się na osobistym doświadczeniu menedżerów. Jednak konsekwencje tychże decyzji mogą mieć wpływ na rozwój codziennych działań. Aby zilustrować wpływ podejmowania decyzji na zarządzanie, przeanalizowana zostanie największa afrykańska firma energetyczna z siedzibą w RPA. Różnorodne dane, takie jak: roczna produktywność i sprzedaż energii, zostały wyodrębnione z raportów rocznych z 15 lat. Do analizy wyodrębnionych danych wykorzystano dwie techniki sztucznych sieci neuronowych o nazwach: Levenberg-Marquardt i Scaled Conjugate Gradient. Z uzyskanych rezultatów badań wynika, że w latach 2018-2020 firma doświadczyła dynamicznego wzrostu, który w najlepszym przypadku może potrwać do 2025 r po czym spoadnie do poziomu z 2020 r. Uzyskane wyniki można zatem wykorzystać do wzmocnienia procesu decyzyjnego i określenia momentu, w którym należy podjąć decyzje zapobiegające upadkowi firmy.

In the digital society, states’ information security has become one of the key elements of ensuring the competitiveness and sustainable development of the state, guaranteeing its integrity and security in general. An important component of state security is the internal security of the state, which must ensure the personal and public safety of its citizens. Modern Ukraine is building a new system of criminal justice, which requires a new information system for risk assessment and support for optimal decision-making. Today, applied research and the development of information and analytical software for the internal security of the state have acquired a special meaning. In the paper, there is built a set of models for providing operational information for decision-making in criminal justice. This is a cluster model for creating criminal profiles of convicts, and a scoring model for identifying individual characteristics of criminals that have the greatest impact on their propensity to reoffend. The obtained models can provide reliable support for decision-making in the field of criminal justice and become part of the information support system for the internal security of Ukraine in general.

The paper aims to identify how Industry 4.0 technologies affect the quality and speed of the managers’ decision-making process across the different stages of the value chain, based on the example of the manufacturing sector. The paper adopts qualitative research, based on nine in-depth interviews with key informants, to capture senior executives’ experiences with implementing Industry 4.0 technologies in their organisations. The research is focused on three manufacturing industries: the automotive, food and furniture industries. The research shows that depending on the stage of the value chain, different Industry 4.0 technologies are more suitable for the support of managers’ decisions. Various Industry 4.0 technologies support decisionmaking at different stages of the manufacturing value chain. In the Design stage, 3D printing and scanning technologies play a crucial role. In the case of Inbound Logistics, robotisation, automation, Big Data analysis, and Business Intelligence are most useful. During the Manufacturing stage, robotisation, automation, 3D printing, scanning, Business Intelligence, cloud computing, and machine-to-machine (M2M) integration enable quick decision-making and speed up production. Sensors and the Internet of Things (IoT) optimise distribution in the Outbound Logistics stage. And finally, Business Intelligence supports decisions within the Sales and Marketing stage. It is also the most versatile technology among all particular stages. The paper provides empirical evidence on the Industry 4.0 technology support in decision-making at different stages of the manufacturing value chain, which leads to more effective value chain management, ensuring faster and more accurate decisions at each value-chain stage. When using properly selected Industry 4.0 technologies, managers can optimise their production processes, reduce costs, avoid errors and improve customer satisfaction. Simultaneously, Industry 4.0 technologies facilitate predictive analytics to forecast and anticipate future demand, quality issues, and potential risks. This knowledge allows organisations to make better decisions and take proactive actions to prevent problems.

The intuitionistic fuzzy sets (IFSs) have a more significant contribution to describing and dealing with uncertainty. The intuitionistic fuzzy measure is a significant consideration in the field of IFSs theory. However, Pythagorean fuzzy sets (PFSs) are an extension of the IFSs. PFSs are more capable of modelling uncertainties than IFSs in real-world decision-making scenarios. The majority of PFSs research has concentrated on establishing decision-making frameworks. A similarity measure is a key concept which measures the closeness of PFSs. IFSs-based similarity measures have been proposed in the literature. This type of similarity measure, however, has a drawback since it cannot satisfy the axiomatic definition of similarity by offering counter-intuitive examples. For this study, a similarity-based on logarithmic function for Pythagorean fuzzy sets (PFSs) is proposed as a solution to the problem. A decision-making approach is presented to ascertain the suitability of careers for aspirants. Additionally, numerical illustration is applied to determine the strength and validity of the proposed similarity measures. The application of the proposed similarity measures is also presented in this article. A comparison of the suggested measures with the existing ones is also demonstrated to ensure the reliability of the measures. The results show that the proposed similarity measures are efficient and reasonable from both numerical and realistic assessments.

This research is focused on decision-making problems with redundant and incomplete information under a fuzzy environment. Firstly, we present the definition of incomplete fuzzy soft sets and analyze their data structures. Based on that, binary relationships between each pair of objects and the “restricted/relaxed AND” operations in the incomplete fuzzy soft set are discussed. After that, the definition of incomplete fuzzy soft decision systems is proposed. To reduce the inconsistency caused by the redundant information in decision making, the significance of the attribute subset, the reduct attribute set, the optimal reduct attribute set and the core attribute in incomplete fuzzy soft decision systems is also discussed. These definitions can be applied in an incomplete fuzzy soft set directly, so there is no need to convert incomplete data into complete one in the process of reduction. Then a new decision-making algorithm based on the above definitions can be developed, which can deal with redundant information and incomplete information simultaneously, and is independent of some unreliable assumptions about the data generating mechanism to forecast the incomplete information. Lastly, the algorithm is applied in the problem of regional food safety evaluation in Chongqing, China, and the corresponding comparison analysis demonstrates the effectiveness of the proposed method.

Transportation appraisal has a potential important role in prioritization of transportation investment projects and other transportation measures. Appraisal practices vary much over countries and time, but these differences are not fully known. More knowledge on the variation in practices may contribute to smoother knowledge exchange between countries and more informed choices in the further development of each national practice. In this paper, we present both an updated mapping and a meta-analysis of impact coverage in national appraisal guidelines for transportation measures and spatial measures more generally. Our updated mapping of impact coverage covers 18 national and regional guideline sets and 44 sorts of impact. It shows rather similar overall impact coverage in the reviewed guidelines for economic, social and environmental impacts. The most advanced appraisal practices are found in Northern and Western Europe and Oceania. We find that supplementary quantitative analyses are most common for economic impacts, while multi-criteria analyses are most common for environmental impacts. Our meta-analysis covers ours and 15 earlier impact mappings, jointly covering 42 countries and regions. In this examination, we show how impact coverage in appraisal practices has improved over time, particularly for environmental, user and wider economic impacts. The meta-analysis also reveals that Western and Northern European and Oceanian countries and dependencies have had the widest impact coverage from 1998 to 2020, both in CB and overall. To examine what characterize countries with broad and narrow impact coverage, we have applied econometric regression models that are linear (i.e. linear least squares), quasi-linear (i.e. Tobit) and fractional response-based (i.e. fractional probit and fractional logit). In these regression analyses, we control for study-specific characteristics and clustering the standard errors on countries. Our results show that the CB impact coverage tends to increase with economic wealth, equality and population size in developed countries, while we find no such patterns for overall impact coverage.

This paper aims to examine how specific domestic social, political, and cultural motives impact national security agendas’ formation and implementation. The following assumptions drive this essay’s research rationale: Security-making processes are considered non-similar among states due to different domestic political processes, cultural discourses, and socialisation patterns. Therefore, national security agents are constantly being guided by various intrastate settings, which construct attitudes that are ultimately reflected upon policy formation and implementation through strategic behavioural manifestations. Thus, the realisation of national security is dependent on each state actor’s existent strategic culture, and given that, choices cannot be contemplated strictly under rationality. The methods of literature review and multi-layered analysis are applied throughout this study. In particular, this text’s reasoning is based on contextualisation, identification, categorisation of variables, and correlational implications. Concerning findings, the theoretical examination of the objects assessed provides adequate clarifications on the interaction among the domestic motives, decision-makers’ perspectives, and strategic cultural manifestations. Specifically, it was critically identified that the two last concepts may complementary function during security-making processes; hence, producing unique outcomes for each state actor. Consequently, this paper wishes to contribute by giving direction for future research and broader methodological implications on the role of intrastate socio-political and cultural motives as sources of strategic culture and determinants of national security-making attitudes; without ignoring that other factors can respectively affect the aforementioned schemes.

In order to strengthen public health management, the main aim of the study was to identify possible changes in alcohol consumption during the health crisis, classified according to the socio-economic status of the Slovak population. The research sample consisted of 506 respondents (33% males and 67% females), and data were collected through an online questionnaire distributed from 29th of April 2020 to 1st July 2020. A crosstabulation showed that alcohol consumption did not change in about half of the respondents, while the majority of the remaining respondents reported a decrease in alcohol consumption compared to those who reported an increase. Females were more stable in their drinking than males. Correspondence analysis showed that high-income males (2500 to 2999 EUR) were more likely to drink excessively. Conversely, high-income females reported much less alcohol consumption. Health care professionals should pay increased attention to alcohol consumption in vulnerable groups at risk of developing an addiction. The findings of this study provide valuable information for improving public policy management and for effective decision-making in public health.

W celu wzmocnienia zarządzania zdrowiem publicznym, głównym celem badania była identyfikacja możliwych zmian w spożyciu alkoholu podczas kryzysu zdrowotnego, sklasyfikowanych według statusu społeczno-ekonomicznego ludności słowackiej. Próba badawcza składała się z 506 respondentów (33% mężczyzn i 67% kobiet), a dane zostały zebrane za pomocą ankiety internetowej rozprowadzanej od 29 kwietnia 2020 r. do 1 lipca 2020 r. Tabela krzyżowa wykazała, że spożycie alkoholu nie zmieniło się w około połowie badanych, podczas gdy większość pozostałych respondentów zgłosiła spadek spożycia alkoholu w porównaniu z tymi, którzy zgłosili wzrost. Kobiety były bardziej stabilne w piciu niż mężczyźni. Analiza korespondencji wykazała, że mężczyźni o wysokich dochodach (2500 do 2999 euro) częściej nadużywali alkoholu. Z drugiej strony kobiety o wysokich dochodach zgłaszały znacznie mniejsze spożycie alkoholu. Pracownicy służby zdrowia powinni zwracać większą uwagę na spożywanie alkoholu w grupach wrażliwych, zagrożonych uzależnieniem. Wyniki tego badania dostarczają cennych informacji na temat poprawy zarządzania polityką publiczną oraz skutecznego podejmowania decyzji w zakresie zdrowia publicznego.

By discretising the stochastic demand, a deterministic nonlinear programming formulation is developed. Then, a hybrid simulation-optimisation heuristic that capitalises on the nature of the problem is designed. The outcome is an evaluation problem that is efficiently solved using a spreadsheet model. The main contribution of the paper is providing production managers with a tractable formulation of the production planning problem in a stochastic environment and an efficient solution scheme. A key benefit of this approach is that it provides quick near-optimal solutions without requiring in-depth knowledge or significant investments in optimisation techniques and software.

Mining-method selection (MMS) is one of the most critical and complex decision making processes in mine planning. Therefore, it has been a subject of several studies for many years culminating with the development of different systems. However, there is still more to be done to improve and/or create more efficient systems and deal with the complexity caused by many influencing factors. This study introduces the application of the entropy method for feature selection, i.e., select the most critical factors in MMS. The entropy method is applied to assess the relative importance of the factors influencing MMS by estimating their objective weights to then select the most critical. Based on the results, ore strength, host-rock strength, thickness, shape, dip, ore uniformity, mining costs, and dilution were identified as the most critical factors. This study adopts the entropy method in the data preparation step (i.e., feature selection) for developing a novel-MMS system that employs recommendation system technologies. The most critical factors will be used as main variables to create the dataset to serve as a basis for developing the model for the novel-MMS system. This study is a key step to optimize the performance of the model.

The paper provides a multiple-experts Fuzzy-TOPSIS decision-making model for the selection among maintenance contractors based on the quality of tendering documents. The study introduces a set of selection criteria utilizing benefit and cost criteria from literature. The proposed model aggregates subjective linguistic assessments of multiple experts that express their opinions on the degree of importance of criteria and allows multiple decisionmakers to evaluate the compliance of contractors’ documents. For a case study, the model is applied to select among contractors tendering to maintain the heavy-duty cranes of an international steel company from literature. Several decision-making scenarios are investigated, and major changes in the final decision are observed. The changes in obtained results illustrate the need to better address uncertainties in rating and tendering an overqualified contractor at a higher cost.

This paper addresses an application of the specific methods of multi-criteria decision analysis to specify the appropriate supplier of an autonomous train in a certain production–distribution company. This company identifies three potential suppliers dealing with the development and purchase of autonomous train systems. In terms of the multi-criteria decision analysis, the WSA method, the Scoring method and the TOPSIS method were used to define a suitable compromise solution. To apply each method, individual suppliers were sorted depending on the appropriateness for the examined company based on relevance with all the identified criteria and their weights. The evaluation criteria include procurement cost, time of the whole autonomous train system project implementation, references from plants where such a technology has already been introduced, service department availability and battery charge time. Thereafter, the outcomes obtained using individual methods were compared to each other and the compromise supplier of the autonomous train system to be implemented in the selected company was determined.

Introduction/background: This paper’s aim is to contribute to overcoming the limitations of existing policies intended to facilitate innovativeness. This article addresses the need for more tailored and targeted innovation support measures for small and medium-sized enterprises (SMEs) to help maximize their economic and societal impact. Aim of the paper: Specifically, the aim is to advance methodological frameworks for segmenting or selecting innovative SMEs by providing a conceptual proposition based on the innovation cycle at the firm level. Materials and methods: This objective is achieved by exploring the literature on the innovation cycle concept, and adapting the model developed by Abernathy and Utterback (the A–U model) for the purpose of innovation policy. Particular phases of the innovation cycle are transformed into variables and values, and based on the research regarding the behaviour of SMEs illustrative weights are assigned; this assignment depends on the preferred policy approach: either supporting innovativeness in and of itself or supporting innovativeness and an SME’s standing in the long run. Results and conclusions: As a result, the paper presents a tentative working procedure for assessing enterprises according to operationalized criteria derived from the A–U model. Added to this, collaborative efforts in developing innovations are briefly discussed from the innovation policy perspective. It is believed that the new conceptual proposition outlined in the paper will be instrumental in segmenting companies and selecting innovative projects, and will serve policy-makers and intervention organizations in the implementation phase of the innovation policy process, thus contributing to a more efficient and transparent allocation of support instruments by public institution.

The triggering of a “dirty bomb” generates a complex scenario, with enormous challenges for the responders due to initial misinformation and the urgency to act quickly yet effectively. Normally, the first 100 h are decisive for perceiving the risk in a more realistic dimension, but the support of methodologies that rely on computational simulations can be valuable when making key decisions. This work seeks to provide support for the early decision-making process by using a Gaussian model for the distribution of a quantity of Cs-137 spread by a radiological dispersive device (RDD). By sequentially joining two independent programs, HotSpot Health Physics codes and RESidual RADiation (RESRAD)-RDD family of codes, we came up with results that suggest a segmented approach to the potentially affected population. These results advocate that (a) the atmospheric stability conditions represented by the Pasquill–Gifford classes and (b) the population subgroups defi ned by radiation exposure conditions strongly influence the postdetonation radiological effects. These variables should be taken into account in the elaboration of flexible strategies that include many climatic conditions and to prioritize attention to different groups of public at risk. During the initial phases of such an event, it is believed that simulations using Gaussian models may be of value in anticipating the possible changes in key variables during the decision-making process. These variables may severely affect the effectiveness of the actions of responders and the general public’s safety.
