Opis:
Research background: Although some authors propose that economic growth should reduce crime rates as wider opportunities to earn money in a legal way diminish the incentives to commit illegal activities and lead to rising costs of the latter, the results of many studies indicate that an increase in crime rates is also possible under the conditions of economic growth. There are also differing views on the relationship between various economic indicators and crime rates as well as the nature of the relationship between the above-mentioned phenomena in the long and short run. Purpose of the article: After classifying the EU member states by their crime and economic indicators, the main objective of the article is to assess the relationship between the crime and economic development and identify the causes of this relationship. Methods: Systematic and comparative literature analysis, the Promethee and Entropy methods, Spearman?s correlation coefficient. Findings & value added: The Promethee method, together with the Entropy method, were used to estimate the weights of the EU member states with respect to their crime and economic development indicators. The most pronounced differences were recorded in Portugal, Spain, and the Slovak Republic. The rankings estimated for the EU member states revealed that although economic situation affects crime rate, it can also be affected by the differences in cultural and political development. Scientific novelty lies in complementing the theory of the shadow economy with the results showing that compared to other crimes, corruption has the greatest weight when examining the relationship between economic development and crime. The practical significance of the research lies in classifying the EU member states into 4 groups with consideration of the relationship between crime and economic development, which may help public authorities to devise the target measures for the effective fight against crime given the nature of the relationship between crime and economic development.

Opis:
The Logistics Performance Index (LPI), created by the World Bank, is a benchmark tool used to determine the threats and opportunities faced by countries in their logistics performances and to improve their performances. Countries aim to increase their LPI scores and rank higher on the LPI list while developing their strategies. Methods: In this study, it was aimed to compare the domestic logistics performances of Turkey and the European Union countries with an integrated model using the domestic logistics performance index data for 2018, which was recently published by the World Bank. In this direction, firstly, the importance levels of the criteria were determined with the CRITIC (Criteria Importance Through Intercritera Correlation) method, and then, using the importance levels of the criteria, the countries were ranked according to the domestic logistics performance score with the COPRAS (Complex Proportional Assessment) method. Results: As a result of the CRITIC method, the most important criterion in the ranking according to the importance levels of the criteria was “without physical examination”, which is the sub-criterion of the customs clearance period, while the Netherlands was the country with the best performance in the ranking performed by the COPRAS method, using the importance levels of the criteria determined by the CRITIC method. Conclusions: The study differs from current studies in the literature in that it is the first study to perform a domestic logistic performance comparison using CRITIC and COPRAS methods with an integrated model. The results of the current study can be compared with the results obtained by using different integrated models and different data in the studies to be conducted.
Wskaźnik Logistics Performance Index (LPI), utworzony prze Bank Światowy, służy do benchmarkingu w określaniu zagrożeń i możliwości dla krajów w ich działalności logistycznej oraz dla działań w celu poprawy tej działalności. Państwa dążą do poprawy wartości swojego wskaźnika LPI poprzez ciągła poprawę swojej strategii działania. Metody: Celem pracy jest porównanie wskaźników krajowej działalności logistycznej Turcji oraz krajów Unii Europejskiej ze zintegrowanym modelem w oparciu dane za 2018 rok, opublikowane niedawno przez Bank Światowy. W tym celu wpierw określono ważność poszczególnych kryteriów przy pomocy metody CRITIC (Criteria Importance Through Intercritera Correlation), a następnie utworzono ranking krajów dotyczących ich działalności logistycznej przy użyciu metody COPRAS (Complex Proportional Assessment). Wyniki: Używając metodę CRITIC, ustalono, że najważniejszym kryterium w ranking było kryterium „bez badania fizycznego”, które jest podkryterium w okresie odpraw celnych. Holandia umiejscowiła się na pierwszym miejscu rankingu stworzonego przy użyciu metody COPRAS. Wnioski: Prezentowana praca różni się od prac obecnie publikowanych użyciem metody porównawczej, wykorzystującej metody CRITIC oraz COPRAS w odniesienie do zintegrowanego modelu. Jednak otrzymane wyniku mogą być porównywane z wynikami uzyskanymi przy zastosowaniu innych modeli zintegrowanych oraz na podstawie innego zestawu danych.

Opis:
The paper presents a framework for optimising a sailing yacht rig using Multi-objective Evolutionary Algorithms and for filtering obtained solutions by means of a Multi-criteria Decision Making method. A Bermuda sloop with discontinuous rig is taken under consideration as a model rig configuration. It has been decomposed into its elements and described by a set of control parameters to form a responsive model which can be used for optimisation purposes. Considering the contradictory nature of real optimisation objectives, a multi-objective approach has been chosen to address this issue. Once the optimisation process is over, a Multi-criteria Decision Making method based on a w-dominance relation is applied for filtering out the most interesting solutions from the obtained Pareto set. The proposed method has been implemented, and selected results are provided and discussed.

Opis:
Occupational accidents on board criteria determining is a challenging procedure in shipping industry as the ideal safety ship management strategy depends on many factors involving in shipping transportation There are many legislations, agreements and practices to obtain series of security measures in order to ensure safety and security of seafarers. Causes of on-board occupational accidents need to be evaluated in a correct manner to regulate more functional practices and also to lower the on-board accident rates. However, causes of on-board accidents can be extremely complex. Therefore, scientific methods should be used to evaluate the causes and to determine the measures to be taken. The evaluation of the parameters is of great importance for the future of the maritime sector and in terms of development. In this study, factors have been identified that lead to seafarers? occupational accidents on board and we tried to present alternative solutions which can be applied on this issue. Severity of the reasons that led to the accidents and their relationships with each other are identified to be able to sort through the alternative solutions with a model using the fuzzy AHP (Analytic Hierarchy Process) method approach. Results of the study revealed that the most important criteria for the occupational accidents on board criteria selection are respectively; human factors, lack of management, ship-borne troubles, cargo troubles and environmental factors.

The current collapsible pot hauler uses a wooden frame, thus making much space in the working area of the fishing boat and also at this time challenging to find the best quality wood at this time. In this study, the wood material would replace by metal; the selection of the proper material is critically needed. A suitable material means the applied material has to deal with environmental conditions. Finding the appropriate material applied to the collapsible pot hauler; can be determined using a Multi-Criteria Decision Making (MCDM) approach. After selecting the proper material, the collapsible pot hauler simulates the material stress using the Finite Element Analysis (FEA) simulation. The material for the new model of collapsible pot hauler was selected using the WSM method. The material with the highest rank (selected) is AISI 304, with a preference value of 3.58. The static strength simulation using the FEA method utilizing Solidworks Software shows that the yield strength value is still below the material properties, which a maximum value is 200. MPa, the material safety factor is the minimum value above one, which is 1.24 on the line spool plate shafts. It means that the material AISI 304 is safe to be applied to the collapsible pot hauler.

Opis:
Supply chain management firms are gradually pressurized to incorporate social sustainability practices to address social issues. Though, the researchers emphasized on different dimensions of sustainable supply chain management (SSCM), i.e., social, environmental and economic but fewer considered the social aspect of sustainability. The purpose of this research is to take into account the social dimension of sustainability into manufacturing industries. The social dimension of sustainability as compared to other sustainable, has severe adverse impact across supply chains. In order to demonstrate the applicability and efficiency of social sustainability in supply chain management, a sample of 53 practitioners of Pakistani manufacturing companies has been selected to prioritize and evaluate the SCSS criteria by applying a decision-making multi-criteria method called the best worst method (BWM). The criteria of the study are ranked according to their average weight achieved through BWM. The criterion employment practices has been chosen as the most significant criterion while cultural values criterion is considered as least important. The results of this study are helpful for industry managers, practitioners and decision-makers to take the decisions for the implementation of social criteria to enhance the social sustainability that lead to sustainable development.
Firmy zarządzające łańcuchem dostaw są poddawane presji, aby wprowadzić praktyki zrównoważonego rozwoju społecznego w celu rozwiązania problemów społecznych. Chociaż naukowcy zwracają uwagę na różne wymiary zrównoważonego zarządzania łańcuchem dostaw (SSCM), tj. społeczny, środowiskowy i ekonomiczny, jednak należy zauważyć, że w najmniejszym stopniu dyskutowane są aspekty społeczne. Celem tych badań jest uwzględnienie społecznego wymiaru zrównoważonego rozwoju w przemyśle wytwórczym. Społeczny wymiar zrównoważoności, w porównaniu z innymi, ma poważny negatywny wpływ na łańcuchy dostaw. W celu wykazania możliwości zastosowania i efektywności zrównoważoności społecznej w zarządzaniu łańcuchem dostaw, wybrano próbę 53 praktyków z pakistańskich firm produkcyjnych w celu ustalenia priorytetów i oceny kryteriów SCSS poprzez zastosowanie wielokryterialnej metody decyzyjnej zwanej najlepszą/najgorszą metodą (BWM). Kryteria badania są uszeregowane według ich średniej wagi osiągniętej w BWM. Kryterium dotyczące zatrudnienia zostało wybrane jako najistotniejsze, natomiast kryterium wartości kulturowych jest uważane za najmniej ważne. Wyniki tego badania są pomocne dla menedżerów branży, praktyków i decydentów w podejmowaniu decyzji dotyczących wdrażania kryteriów społecznych w celu zwiększenia zrównoważości społecznej, która prowadzi do zrównoważonego rozwoju.

Opis:
Multi-criteria decision-making (MCDM) is one of the most popular problems handled by researchers in the literature. Since the interval-valued intuitionistic fuzzy set (IVIFS) theory generates as realistic as possible evaluation of linguistic expressions, researchers have been expanding traditional MCDM methods to the IVIF environment, especially in the last decade. This study provides a literature review of the relevant articles from several academic databases on applications of IVIF-MCDM methods. The review of 131 publications addresses specific research questions. To understand the research publication trend, this review offers a visual analysis that examines the studies from different perspectives, such as application areas, IVIF-MCDM methods, citations, most relevant journals, and validation methods. One of the most remarkable results of the literature review is that most publications in this field are published in SCIE indexed journals. Another noteworthy issue is that China is the country that produces the most articles in this field. In addition, English journals are mostly selected for the publication of articles. While it is seen that the investment selection problem is chosen mostly as the application area, the TOPSIS method is preferred mostly in the applications. This study stands out as the most comprehensive one that compiles publications containing extended traditional MCDM methods for IVIF sets. This review will be an important reference for future researchers and decision-makers involved in advancing MCDM methods considering vagueness and ambiguity.

The aim of this study is to determine the optimum location for an oil spill response center in the Marmara Sea. The analytic hierarchy process (AHP) and technique for the order of preference by similarity to ideal solution (TOPSIS) method as the most preferred multi-criteria decision-making (MCDM) technique were used. The results reveal that the LOC criterion and PRA sub-criterion have the highest effects on the optimal location selection of the oil spill response center. According to the results, the most suitable location for the oil spill response center in the region is Izmit Bay Entrance. This location has been proposed for the response headquarters to manage the whole operation with the assistance of auxiliary installations in the area. In this study, only technical and operational variables are taken into account, but political and administrative criteria are excluded.

Management processes in an organization involve decision-making based on many criteria (MCDM), and in this process ranking of variables plays a vital role. This paper presents the analysis of key business issues of an Indian automotive organization using an efficient interpretive ranking (eIRP) approach. This paper integrates the Situation-Actor-Process (SAP) and Learning-Action-Performance (LAP) framework of the organization with eIRP. It evaluates the ranking of actions to be carried out in an organization with respect to performance parameters. The study highlights the area where the organization should focus on achieving desired business excellence. From the analysis, it is revealed that the top-ranked suggested action for the organization is the adoption of energy policy as a core business policy followed by technology management, maintenance management, and the use of information technology for cost management. This case study is one of the few that uses the SAP-LAP framework for ranking the actors and actions of the organization using the eIRP approach, to make MCDM an easy task.

Inland waterway transport (IWT) is currently in focus for EU countries due to a shift in policy towards a more sustainable and green economy. The aim of this article is to analyze the possibility of using a grey incidence analysis (GIA) to identify key factors related to the functioning of the IWT system. GIA is classified as a multi-criteria decision-making method and is one of the key applications of grey systems theory (GTS), i.e., systems with incomplete and uncertain information about structure and behavior. GIA identifies the most favorable (or quasi-preferred) system characteristics and the most favorable (or quasi-preferred) system factors. The identification of such characteristics and factors enables a reduction in the inconsistencies in decision making on the functioning of the system. The application of the GIA to the assessment of the IWT system is an original concept.

Opis:
Supplier selection and evaluation are among the most critical issues in supply chain management, affecting companies’ performance because of the important role of suppliers in the chain’s profitability. For this reason, it is important for companies to have an objective methodology to evaluate and choose an appropriate supplier based on convenient criteria in a competitive market. Determination of a convenient supplier selection is a multi-criteria decision-making (MCDM) problem. In the literature, several applications of the MCDM methods for supplier evaluation and selection can be found; however, research studies in the clothing industry are still limited. Indeed, apparel supply chain managers have to consider their supplier-related decisions to reduce risks affecting the company’s performance. This study aims to fill this gap by providing apparel manufacturers with different hybrid models for selecting the best supplier. According to a literature review and questionnaire conducted, the main criteria related to supplier selection were identified and determined. Then, the analytic hierarchy process method was performed to determine the criteria’s weights, and then suppliers were ranked using hybrid multicriteria decision-making models (AHP-TOPSIS, AHP-WSM, and AHP-WPM) to select the suitable one in the apparel chain. This research methodology can be considered useful for apparel companies and other industries.

This paper presents a practical case involving a shopping mall location problem in the northeast countryside of Brazil. In this problem, conflicting objectives have been expressed in terms of seven criteria. Then, ten cities of the northeastern countryside have been selected to compose the space of actions. The problem plays a special role since Brazil is a big country that requires investments in the countryside. Thus, the shopping mall aims to stimulate economic growth in the respective region. In the study, this multi-objective problem is solved using the FITradeoff method. In FITradeoff, the combination of the paradigms of holistic evaluation and elicitation by decomposition in preference modeling are well explored, bringing different perspectives for the decision-maker during the decision process.

Opis:
The ready-to-wear sector is one of the areas where outsourcing is used extensively due to reasons such as being a labour-intensive sector, having a wide range of products, and the time pressure caused by the very short shelf life of the product. Therefore, garment companies work with a large number of subcontractors, which raises the problem as to which subcontractor/subcontractors work will be distributed to as well as how much to each subcontractor. Using multi-criteria decision-making methods in solving this complex problem helps decision-makers make the right decisions. From this point of view, multi-criteria decision-making methods are very important decision-making tools in terms of the optimal distribution of work to subcontractors. Within the scope of the study, the TOPSIS and AHP methods were used to distribute orders to subcontractors and compared.
Sektor odzieżowy jest jednym z obszarów, w których szeroko stosowany jest outsourcing, głównie z takich powodów, jak: pracochłonność sektora, szeroka gama produktów oraz presja czasowa spowodowana bardzo krótkim okresem trwałości produktu. Dlatego firmy odzieżowe współpracują z dużą liczbą podwykonawców, co rodzi problem, do jakiego podwykonawcy/podwykonawców zostanie przydzielona praca, a także do jakiej kwoty zostanie przydzielona każdemu z podwykonawców. W podejmowaniu właściwych decyzji w kwestii tego złożonego problemu pomaga decydentom możliwość korzystania z wielokryterialnych metod podejmowania decyzji. Z tego punktu widzenia wielokryterialne metody podejmowania decyzji są bardzo ważnymi narzędziami decyzyjnymi z punktu widzenia optymalnego podziału pracy na podwykonawców. W ramach badania wykorzystano metody TOPSIS i AHP do dystrybucji zamówień do podwykonawców i porównano je.

Opis:
Human error is recognized as the most common factor that causes maritime accidents. The human error assessment and reduction technique (HEART) is a human reliability assessment (HRA) that has been widely applied in various industries. Furthermore, the HEART – 4M method has been proposed to assess maritime accidents. The HEART – 4M method can clearly define the relationship between man, machine, media, and management factors and the human error. However, the calculation process to determine the weight of every selected error-producing condition (EPC) suffers from the uncertainty of the assessor's estimation in practical applications, which may affect the objectivity of its result. In this study, a modification of the HEART – 4M method with the technique for order preference by similarity to ideal solution (TOPSIS) is proposed. TOPSIS is a multi-criteria decision making (MCDM) tool. This study aims to develop the HEART – 4M method to make it more comprehensive and objective when assessing maritime accidents. First, the parameter of the generic task is determined as in the conventional HEART method. Second, the causal factors are converted to the suitable EPC – 4M, and there are four classification factors for the 38 standard EPCs, which are divided into man, machine, media, and management factors. Third, the TOPSIS is applied to handle the problems of interdependencies and interaction among EPC – 4M and the uncertainty that exists in the assessor´s judgment. The proportion effect of each EPC – 4M is determined through TOPSIS by considering the correlation among EPC – 4M. Finally, thirteen collision data obtained from the National Transportation and Safety Committee of Indonesia are assessed to apply the proposed method.

Opis:
The use of robotic equipment and a new technique called contour crafting allows for the construction of buildings at lower labor and material costs. The selection of the type of robot is an important factor that affects the overall performance of the contour crafting (CC) system. Various robot configurations, such as gantry, cylindrical, and SCARA, may be employed for contour crafting. There are benefits and drawbacks to using different types of robots for various tasks, including cost, work volume, material compatibility, and precision. Identifying a proper robot using the multi-criterion decision-making (MCDM) technique is crucial for successful building automation. This article uses the analytical hierarchy process (AHP) method to rank the best robots according to several characteristics. Cartesian robots, cylindrical robots, and SCARA robots were evaluated based on cost, accuracy, work volume, surface finish, type of profile, and speed. The results showed that the gantry-type robot is the most suitable option, while the cylindrical robot is unsuitable for building construction due to lower accuracy.
