Opis:
Road construction has been an ongoing engineering practice throughout human history. Although road construction technologies have changed over time, the raw material used has not changed for centuries, and it seems that it will not change in the upcoming centuries. Although some standards are used to determine the aggregate quality in road construction works, it is often complex and laborious to identify the aggregates that best meet the standards. Long-lasting and high-quality roads can be built and the most suitable aggregate is selected for the road. This study aims to select the most suitable aggregates used in hot-mix asphalt pavement production for road construction. In this study, multi-criteria decision-making methods were used for the selection of the aggregate that provides the best conditions. Aggregates used in constructing roads within the provincial borders of Ankara are produced from six stone quarries. To rank these aggregates and determine the ideal quarry for hot-mix asphalt production, the analytical hierarchy process (AHP) and the technique for order preference by similarity to an ideal solution (TOPSIS) method, which are multi-criteria decision making (MCDM) methods, were used. The results obtained from the tests on aggregates and hot-mix asphalts (HMA) were compared with the the best results based on the maximum and minimum limits determined in the standards. By comparing the the best results of the standards with the test results of the aggregates, weight scores were made for each test. Weight scores were scored and classified using the AHP and TOPSIS multi-criteria decision-making methods. As a result, the aggregate with the highest score and the quarry area represented by the aggregate were determined as the most suitable for hot-mix asphalt construction.
Budowa dróg była stałą praktyką inżynierską w całej historii ludzkości. Choć technologie budowy dróg zmieniały się na przestrzeni dziejów, to stosowany surowiec nie zmienia się od wieków i wydaje się, że nie zmieni się w kolejnych stuleciach. Chociaż niektóre normy są stosowane do określania jakości kruszyw w robotach drogowych, to często skomplikowane i pracochłonne jest uszeregowanie kruszyw spełniających te normy. Trwałe i wysokiej jakości drogi można budować przy użyciu najodpowiedniejszego kruszywa dobranego do drogi. Niniejsze opracowanie ma na celu wybór najodpowiedniejszych kruszyw do produkcji nawierzchni asfaltowych na gorąco do budowy dróg. W niniejszym badaniu zastosowano wielokryterialne metody decyzyjne do wyboru agregatu, który zapewnia najlepsze warunki. Kruszywa wykorzystywane do budowy dróg w granicach prowincji Ankary produkowane są w sześciu kamieniołomach. Aby uszeregować te agregaty i określić idealny kamieniołom do produkcji gorącej mieszanki asfaltowej, zostały użyte: analityczny proces hierarchiczny (AHP) i technika preferencji zamówień na podstawie podobieństwa do metody idealnego rozwiązania (TOPSIS), które są metodami wielokryterialnego podejmowania decyzji (MCDM). Wyniki uzyskane z badań kruszyw i asfaltów na gorąco (HMA) porównano z najlepszymi wynikami wynikającymi z maksymalnych i minimalnych limitów określonych w normach. Porównując najlepsze wyniki wzorców z wynikami testów agregatów, dla każdego testu wykonano oceny wagowe. Oceny wagowe zostały ocenione i sklasyfikowane przy użyciu wielokryterialnych metod podejmowania decyzji, AHP i TOPSIS. W rezultacie kruszywo z najwyższą punktacją i obszar kamieniołomu reprezentowany przez kruszywo zostały uznane za najbardziej odpowiednie do budowy gorących mieszanek mineralno-asfaltowych.

Opis:
The Analytical Hierarchy Process (AHP) is one of the multi-criteria methods with tools that are effective for decision-making in complementary or alternative medicine (CAM). This approach, in combination with other available methods, such as the Utrecht Method, allows medical professionals and patients themselves to take a balanced choice of special treatment and health control. This is particularly important for pregnant women who suffer from nausea and vomiting during pregnancy (NVP). The mechanisms of toxicosis occur, and the way of treatment have certain uncertainties. The decision-making process for therapeutic care must consider several factors, the determination of which is the result of collaboration between the patient and the healthcare provider. This paper presents the results of a decision-making study regarding the use of the ginger medicinal plant in helping a woman with NVP symptoms. The research was conducted using the original questionnaire according to the methodology proposed by the developers of the Utrecht Method. The chosen respondents were healthcare professionals with experience in treating NVP and pregnant women. The Analytical Hierarchy Process (AHP) capabilities in decisionmaking were shown in an example of analyzing the benefits, risks, and side effects of using ginger during pregnancy. The combination of two methodological approaches allowed to successfully connect the proven facts of using CAM therapy with the subjective assessment of all stakeholders. The study demonstrates that this approach successfully uses decision-making by structuring hierarchical decision elements and weighing the criteria involved in the decision-making issue. The article examines the practicality and effectiveness of using AHP when making decisions regarding the treatment and improvement of the condition of pregnant women with NVP, and summarizes the quantitative and qualitative indicators of the effectiveness of this method. The presented combination of two methodological approaches in decision-making allows for choosing an optimized medical strategy for supporting pregnant women through CAM therapy.

Opis:
The linguistic q-rung orthopair fuzzy (Lq-ROF) set is an important implement in the research area in modelling vague decision information by incorporating the advantages of q-rung orthopair fuzzy sets and linguistic variables. This paper aims to investigate the multicriteria decision group decision making (MCGDM) with Lq-ROF information. To do this, utilizing Hamacher t-norm and t-conorm, some Lq-ROF prioritized aggregation operators viz., Lq-ROF Hamacher prioritized weighted averaging, and Lq-ROF Hamacher prioritized weighted geometric operators are developed in this paper. The defined operators can effectively deal with different priority levels of attributes involved in the decision making processes. In addition, Hamacher parameters incorporated with the proposed operators make the information fusion process more flexible. Some prominent characteristics of the developed operators are also well-proven. Then based on the proposed aggregation operators, an MCGDM model with Lq-ROF context is framed. A numerical example is illustrated in accordance with the developed model to verify its rationality and applicability. The impacts of Hamacher and rung parameters on the achieved decision results are also analyzed in detail. Afterwards, a comparative study with other representative methods is presented in order to reflect the validity and superiority of the proposed approach.

Opis:
The problem of selecting 3PL (Third Party Logistics) suppliers is a major issue in the management of the supply chain and the improvement of the production management of a manufacturing company. A 3PL supplier can be defined as a company that provides contract logistics services to a manufacturer, supplier or main user of a product or service. It is called a third party because the logistics provider does not own the products but participates in the supply chain between the manufacturer and the user of a given product. In actual cases, several decision-makers intervene in the selection of 3PL suppliers and each one has his own points of view and wishes to take into account criteria which are not generally the same for all the decision-makers. Furthermore, the criteria have different weights. In this study, we propose a method to solve this problem. It consists of a combination of the fuzzy Stepwise Weight Assessment Ratio Analysis (SWARA) method with the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The objective is to optimize the decision-making process and have another, more dynamic model and satisfy the needs of the decision-maker. Fuzzy SWARA is one of the new methods being used for ranking evaluation criteria based on decision makers’ expected degree of importance to determine the weights of evaluation criteria (Selçuk, 2019). This method can be used to facilitate estimation of decision makers’ preferences regarding the meaning of attributes in the weight determination process. TOPSIS is a multi-criteria method for identifying solutions from a finite set of alternatives (Behzadian et al., 2012). To the best of our knowledge, this combination has not been developed in the literature, especially in the third-party logistic problems. The proposed model will be implemented to solve a 3PL problem of a company selling steel products.

Opis:
Currently, an important issue in multi-criteria decision-making (MCDM) problems are vagueness and lack of precision of decision-making information because of insufficient data and incapability of the decision maker to process the information. Intuitionistic fuzzy sets (IFS) are a solution to eliminate the vagueness and the uncertainty. While fuzzy sets (FS) deal with ambiguity and vagueness problem, IFSs have more advantages. Moreover, the CODAS-SORT method cannot handle the uncertainty and ambiguity of information provided by human judgments. The aim of this study is to develop an IF extension of CODAS-SORT combining this method with the IFS theory. To achieve this, we use the fuzzy weighted Euclidean distance and fuzzy weighted Hamming distance instead of the crisp distances. A case study of a supplier selection assessment is used to clarify the details of our proposed method.

Opis:
Research background: Individual car transport significantly burdens the environment, especially in the centres of large cities. There is pollution, traffic jams and an increase in overall noise. In the area of passenger car transport, legislation is being significantly tightened. Therefore, there are also increasing demands on public transport operators in the Czech Republic. Previously, most of the fleet consisted of diesel vehicles. These have been gradually replaced by drives that are significantly more environmentally friendly, such as the Compressed natural gas drive. The requirements defined in relation to the reduction of vehicle emissions are increasingly stricter. A number of cities, not only within the European Union, are addressing significant issues concerning the future of public transport. Purpose of the article: The main objective of the article is to demonstrate an in-depth analysis of the operation of transport vehicles in the Statutory City of Ostrava, both from the cost and environmental point of view. The comparison of transport means using CNG, electric and diesel propulsion is made. Specific factors such as the route profile or the environmental impact of the mode of transport are also taken into account. The extent of the data processed and the multidimensional nature of the assessment offer a unique analysis of the problem. The article provides an exact view of the advantages and disadvantages of operating specific means of transport. Everything is based on data on transport operations in the city of Ostrava (the Czech Republic, EU). Methods: The comprehensive evaluation is based on the application of methods from the field of financial accounting, evaluation of measured data from the operation of transport means and, last but not least, on the analysis of empirical data from the given area. The analysed data set is unique due to the time period, as is the multi-criteria evaluation methodology.  Findings & value added: The analysis performed demonstrated the economic viability of operating CNG vehicles. The main added value of the article is the unique multi-criteria evaluation procedure for the vehicles. The paper shows the evaluation of a complex decision problem in the transport field in the form of a case study implemented in the city of Ostrava. The evaluation results then consider both cost and environmental factors, which can be described as a comprehensive and highly innovative approach. The defined assessment can then be applied to other European and world metropolises.

Opis:
Celem artykułu jest przybliżenie koncepcji pomiaru postępu transformacji energetycznej z wykorzystaniem wskaźników kompozytowych. W pierwszej części pracy przedstawiono sposób konstrukcji i opisano własności dwóch popularnych kompozytowych wskaźników transformacji energetycznej publikowanych odpowiednio przez Światowe Forum Ekonomiczne (indeks ETI) i Światową Radę Energetyczną (indeks WETI). W drugiej części pracy przedstawiono autorską koncepcję wyznaczania zmodyfikowanego indeksu ETI (indeks METI) wykorzystującą zaawansowany aparat statystyczny zapewniający minimalizację wpływu uznaniowości w procesie konstrukcji wskaźnika kompozytowego. Proponowaną metodykę METI zastosowano do „przeliczenia” wyników indeksu ETI dla roku 2020. Uzyskane rezultaty znacznie różnią się od „oryginalnego” rankingu ETI, w szczególności co do pozycji Polski. W ostatniej części artykułu omówiono możliwe kierunki dalszych prac i zarysowano główne rekomendacje w zakresie możliwości stosowania zmodyfikowanych wskaźników kompozytowych do oceny postępu transformacji energetycznej w Polsce.
The aim of this paper is to outline the concept of using composite indicators to evaluate the progress of energy transition. The first part of the study presents the construction and properties of two popular composite energy transition indicators published by the World Economic Forum (the ETI index) and the World Energy Council (the WETI index). The second part of the paper is aimed at presenting the novel methodology of determining a particular variant of modified ETI index – the METI index – that is based on advanced statistical tools which minimize the negative impact of arbitral setting of weights in the process of constructing the composite indicators. The new methodology was used to obtain the METI country ranking for the year 2000. In comparison to the original index, the METI2020 turned out to be significantly different, particularly with respect to the position of Poland. The last part of the study depicts possible directions of future research and outlines the main recommendations regarding the possibility of using the modified composite indicators to assess the progress of the energy transition in Poland.

Opis:
Crisp values are insufficient to model real-life situations and imprecise ideas are frequently represented in multicriteria decision aid analysis. In fact, it is difficult to treat the evaluation criteria precisely and to fix exact preferences rating. The triangular intuitionistic fuzzy numbers succeeded to treat this kind of ambiguity in a great deal of research than other forms of fuzzy representation functions. The field of sorting issues is an active research topic in the multiple criteria decision aid (MCDA). This study extended one of the sorting methods, FLOWSORT, for solving multiple criteria group decision-making problems. This extension described the preferences rating of alternatives as linguistic terms which can be easily expressed in triangular intuitionistic fuzzy numbers. To validate our extension, an illustrative example as well as an empirical comparison with other multi-criteria decision making methods is presented.

Opis:
A concern about the current state of relations between industry and the environment is often neglected. However, it is important to underline that industry and sustainability are not mutually exclusive. There are many industrial processes to blame when analyzing the negative impact on current socio-ecological environment. The emerging question is whether companies nowadays are ready to face challenges in the name of sustainability, the future of the planet and generations to come. In addition, an assessment of industrial processes may be very time-consuming and costly in financial terms. This fact allows developing sustainability assessment approach and its measures for keeping track on to evaluate scale of environmental, social and economic changes. The goal of the paper is to develop a multicriteria decision-making approach for sustainability assessment of renewable energy technology. A sustainability assessment approach combines life cycle-based methods integrated with multi-criteria decision-making method based on analytical hierarchy process. The resulting assessment method allows finding a compromise between industry and the environment and identify potential intervention points for further research. As a result of decision-making process, string ribbon technology was considered as the most sustainable. The applicability of the proposed method is assessed based on photovoltaic panels.

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.

Opis:
Global brown coal resources are estimated to be extracted at around 512 million Mg. They are found in over a dozen countries, including primarily: Australia, China, the Czech Republic, Greece, Germany, Poland, Russia, the United States and Turkey. More than 80% of total brown coal production in the EU takes place in: Germany, Poland, Greece and the Czech Republic. This means that the majority of production still uses conventional fuels, including both hard coal and brown coal. Given the current energy needs in the context of brown coal reserves depletion and the impacts of the current climate and energy policies of the EU, it is very important that all new investments in mining and energy complexes based on brown coal resources must be prepared carefully to ensure high production efficiency and minimize negative environmental impacts. This article attempts to solve a problem involving the choice of the location of the opening cut to expose brown coal deposits. Due to the stratified nature of brown coal deposits and the associated open-cast mining technology used in a continuous mining system with bucket wheel excavators, belt conveyor systems and spreaders, the location of the opening cut is not completely random and the number of potential solutions is finite. The multifaceted technical, organizational, economic, social and environmental problems require a holistic approach to this research problem. Such an approach should take the different, often opposing, perspectives of the many stakeholders into account. These issues can be solved using mathematical tools designed for multiple-criteria decision support. With the proposed method, a ranking of alternatives can be created, depending on the predefined location of the opening cut.
Światowe zasoby węgla brunatnego możliwe do wydobycia szacowane są na około 512 mln Mg i koncentrują się w kilkunastu krajach, przede wszystkim: Australii, Chinach, Czechach, Grecji, Niemczech, Polsce, Rosji, Stanach Zjednoczonych i Turcji. Ponad 80% całkowitej produkcji węgla brunatnego w UE koncentruje się w Niemczech, Polsce, Grecji i Czechach. Mając na uwadze aktualne potrzeby energetyczne w horyzoncie wyczerpujących się obecnie eksploatowanych złóż oraz realia obecnej polityki klimatyczno-energetycznej Unii Europejskiej, bardzo istotne jest, aby ewentualna inwestycja w nowy kompleks górniczo-energetyczny oparty na węglu brunatnym była przygotowana w sposób niezwykle staranny, zapewniający wysoką efektywność produkcji oraz minimalizację negatywnego wpływu na środowisko. Celem artykułu jest wskazanie możliwości rozwiązania problemu badawczego polegającego na opracowaniu metody wyboru lokalizacji wkopu udostępniającego pokład węgla brunatnego. Z uwagi na pokładowy charakter zalegania złóż węgla brunatnego oraz związaną z nim technologię eksploatacji metodą odkrywkową z wykorzystaniem przede wszystkim systemów ciągłych układów koparka-taśmociąg-zwałowarka (KTZ), przestrzenna lokalizacja wkopu udostępniającego nie jest dowolna, a liczba rozwiązań skończona. Wieloaspektowość problematyki obejmująca zagadnienia techniczno-organizacyjne, ekonomiczne, społeczne i środowiskowe wymaga holistycznego podejścia do problemu badawczego uwzględniającego różne, często przeciwstawne punkty widzenia. Problem ten może zostać rozwiązany z wykorzystaniem narzędzi matematycznych dedykowanych do wielokryterialnego wspomagania decyzji. Opracowana metoda pozwala na stworzenie rankingu wariantów w zależności od uprzednio zdefiniowanych lokalizacji wkopów udostępniających.

The engineering building of the University Leicester built-in 1963 has been a British icon for decades now. Applications of Robotic technologies are uprising nowadays, which provides a contingency to manipulate the benefits of robotics for executing challenging and precarious facade cleaning processes. This paper surveys the facade cleaning robotic technologies exist in the market. It exhibits the comparative analysis of four notorious robotic facade cleaning solutions namely Sky Pro, Gekko, BFMR (Building Façade Maintenance Robot) and Sirius_c. The comparison is executed using Multi Criteria Decision Analysis (MCDA) and Quality Function Deployment (QFD) techniques. This study analyses the performance of the robots based on the critical parameters such as water consumption, cleaning efficiency, cleaning dimensions and ease of implementation. Although none of these robotic solutions are implemented off the shelf, some adaptation on these solutions is necessary for the development of robotic techniques work successfully in real time. This paper proposes a hybrid robotic solution combining the vacuum pump adhesion and wheeled locomotion for the effective cleaning of the complex external building structure based on the MCDA and QFD analysis. It highlights the significant future research directions in this field.

Opis:
The paper relates to the trading systems supporting traders ma- king decision on the forex market. Typical trading systems using tech- nical analysis generate a buy or sell signal when the technical indicator crosses a given oversell or overbought levels. The paper extends the approach in which the above strict crisp conditions are replaced by fuzzy relations. The indicators are treated not independently as it is in the typical systems but jointly. Currency pairs are compared in the muliticriteria space in which each criterion is dened by a membership function referring to a given indicator. New formulations of the mem- bership functions for dierent indicators are proposed. General ideas of the algorithm generating non-dominated alternatives in the multi- criteria space are presented. The algorithm has been implemented in an experimental system. Computational results for dierent time win- dows using real-world data from the forex market are presented and discussed.

Opis:
The aim of the paper is to present the practical use of a combination involving two multicriteria methods: AHP (analytic hierarchy process) and TOPIS (The Technique for Order of Preference by Similarity to Ideal Solution), in order to expertly assess the level of sustainable development of counties in the West Pomeranian Province in 2010 and 2017. The article was divided into two main parts. The theoretical (methodological) part contains the characteristics of AHP and TOPSIS methods; in turn, the results of the analysis were presented in the empirical part. The main source of statistical data is the annual report published by Statistical Office in West Pomeranian Province, which contains the information on most important development areas (e.g. population, ecology, pollution, health, employment, macroeconomics, transport, tourism, agriculture, etc.). In other words, the purpose of the article is to build a synthetic measure of sustainable development, which will take into account socio-economic determinants for deliberately selected entities from a regional perspective. This approach will allow a detailed analysis of sustainable development according to the adopted criteria for 2010 and 2017, and may be the basis for further investigations in order to look for more complex dependencies among the factors which determine sustainable development of the studied phenomena and objects.
