In many areas of life, uncertainties exist, and decisions under these uncertainties require mathematical data. This study evaluates the investment suitability of real estate companies listed on Borsa Istanbul (BIST) by integrating neutrosophic sets with AHP and TOPSIS methods. The aim is to help investors minimize risks and make optimal decisions in highly uncertain environments. The study defines neutrosophic sets and presents an integrated neutrosophic AHP and TOPSIS model. The past performance of BIST-listed real estate companies was analyzed for investment suitability. Three stock market analysts indicated the importance of various criteria and expressed company statuses using verbal terms, which were converted into neutrosophic scores. Criteria importance weights were calculated with neutrosophic AHP, and company statuses were evaluated with neutrosophic TOPSIS, resulting in a ranking of companies. The study's uniqueness lies in significantly accounting for uncertainty to minimize risks, allowing decision-makers to use unrestricted verbal expressions for uncertainty. This method considers external factors crucial to the stock market, offering a new approach to minimize risks from uncertainties. [ABSTRACT FROM AUTHOR]

In the process of transitioning to digital businesses, managers are faced with numerous decision-making challenges across various domains. This complexity poses a significant hurdle for traditional businesses seeking to embrace digital transformation. To address this challenge, the Preference Selection Index (PSI) and Additive Ratio Assessment (ARAS) methods are utilized for selecting Big Data Analytics (BDA) software, employing multi-criteria decision-making (MCDM) approaches. With a scenario involving 8 alternatives and 7 criteria, the PSI method is employed to establish the weights of the criteria. Subsequently, the ARAS method is utilized to rank the alternatives. The analysis identifies "Ease of Use" as the criterion with the highest importance weight (0.1464), while "Data Workflow" emerges as the least significant criterion (0.1378). Based on the highest utility degree (0.9548), the fifth alternative was identified as the most suitable big data analytics software for this scenario. Furthermore, the proposed method's applicability is validated through comparative analysis with five different MCDM methods, reinforcing the reliability of the obtained results.

Fires in rural and urban areas cause significant loss of life and property within minutes. For this reason, it is very important to respond effectively to fires in a short time. Fire stations need to be placed in appropriate places to reach the scene as soon as possible. As a result of the research on this subject, some criteria are determined by making many researches for the fire station location selection. Multi-Criteria Decision Making method is used to effectively solve the problems in which the determined qualitative or quantitative criteria are evaluated. This method is divided into two: the methods used to determine the weights of the criteria and the methods used to rank the weights. In this study, FUCOM-F (Fuzzy Full Consistency Method), which is one of the methods of ordering the weights, was used. After the literature research and expert opinions for the location selection of fire stations, 6 main criteria and 10 sub-criteria under the main criteria were determined and listed according to the importance of the weights. Then, comparative preferences were made according to the FUCOM-F method, and then optimum fuzzy weights were calculated. The exact weight values were calculated from the obtained fuzzy weights. For this reason, by looking at the final weight values of the main criteria and sub-criteria, a recommendation was made for the selection of the most suitable fire station location.

This study proposes a new multi-criteria decision-making method called Neutrosophic Critic and Neutrosophic Waspas, applied to the problem of determining the level of happiness, which varies by age groups and years within the scope of the 'Life Satisfaction Survey' conducted by the Turkish Statistical Institute. The proposed method follows the basic steps of the well-known Waspas method but differs from the classical case in expressing attribute values using single-valued neutrosophic sets. Additionally, the determination of the weights of selection criteria is not left to the discretion of the decision-maker; instead, the basic steps of the well-known critic method are used. In the presented happiness level determination problem, the alternatives are individuals aged 18-65+ for the years 2003-2022, and the criteria are chosen. The aim of this article is to extend the measurement of happiness levels in the specified age groups each year from 2003 to the present, using a widely used integrated multi-criteria decision-making model to the domain of single-valued neutrosophic sets. Thus, the approach enables dealing with attribute values with a larger uncertainty set. By leveraging the expressive power of neutrosophic set theory, the proposed approach will assist the decision-maker in developing models that can handle uncertainties arising from various reasons, such as insufficient and precise information, perceptual differences, language variables, and personal opinions.

Creating a closed-loop economy by recycling used products is of great importance in terms of ensuring economic and environmental sustainability. In order to maximize the benefit obtained from the recovery process, it is necessary that the products are included in the system according to the most suitable recovery option. One of the most important product types within the scope of the recycling process is rental products, which are covered in this study. Due to the nature of rental products, entering the recycling process frequently makes the need to determine the most suitable recovery option even more important. In the relevant decision process, one of the situations encountered in practice is that different departments of the institutions have different purposes. The values of recovery options may differ according to the relevant purposes. With this study, it is aimed to present a structure where scores can be generated for each recovery option, taking into account the objectives of different departments. In this structure, Spherical Fuzzy AHP (SF-AHP) and Spherical Fuzzy TOPSIS (SF-TOPSIS) from fuzzy Multi-Criteria Decision Making (MCDM) techniques are used in an integrated manner. To demonstrate the validity of the presented approach, an application was made on leased modems in one of Turkey's major telecommunications companies. All possible scenarios have been analyzed and interpreted from various perspectives under different department weights and different situations that the criteria may take. Thus, the effects of the department goals on the criteria were observed and their effects on the decisions could be examined numerically. [ABSTRACT FROM AUTHOR]

This study aims to examine sustainable portfolio selection for conservative investors. In this context, a two-stage approach is proposed. In the first stage, the sustainability scores of stocks are obtained by utilizing expert knowledge through a fuzzy multicriteria decision-making (FMCDM) approach abbreviated as R-FES. In the second stage, a robust optimization problem that takes into account the sustainability score vector, the sample mean vector and the sample covariance matrix is formulated. Moreover, the analytical solution of this problem is given under certain assumptions. In order to introduce the proposed robust theoretical approach, an application on BIST participation sustainability index stocks is made. In the application, it is seen that sustainable investment may not cause performance loss. In addition, the constraint of not taking short positions is found to improve performance while reducing risk and return. [ABSTRACT FROM AUTHOR]

The decision to determine the new product or products to be added to the product mix is one of the important strategic decisions for businesses. In making this decision, besides the conditions such as the demand for the product at the desired level in the competitive environment, the production process and costs are also effective. The application was carried out in a company operating in the cosmetics and cleaning products sector. In the first stage of the two-stage application, a pre-selection was made with multi-criteria decisionmaking methods (AHP and TOPSIS) among the natural products that the company thought to include in the product mix. In the second stage, a simulation model was created and run in Arena Rockwell program for the demand and production processes of the first two alternatives. With this, it is possible to see the status of the manufacturing process before the products are produced in the company. Then with the Process Analyzer tool of the Arena program, by trying different values of controllable variables, it was tried to reach values that would reduce the cost and the amount of lost sales, while increasing the amount of sales at the same time. After determining the most suitable variable values, the final selection was made by selecting the product according to the sales revenue and cost advantage. The study aims to contribute to the literature by carrying out a study that considers both the selection criteria and the manufacturing process in the selection of new products.

It is foreseen that blockchain technology would be more integrated into various fields such as health, law, supply chain and logistics, information technologies, energy, in addition to finance sector. Based on this foresight, the starting point of the study is to determine which features come to the fore in preference of blockchain technology and the sectors where its utilization holds greater significance. In this direction, the study aims to identify the importance level of the features of blockchain technology and the level of preference for adopting blockchain technology across the sectors. In the first stage, the importance level of the features of blockchain technology is determined using the DEMATEL. In the second stage, the preference level for adopting blockchain technology across different sectors is investigated through the WASPAS. The findings show that transparency, independence, and immutability are the three most crucial characteristics of blockchain technology. Furthermore, the law sector, followed by the public sector and insurance sector, are identified as the top three sectors where the preference for utilizing this technology is expected to be the highest. These findings emphasize the need to expand the focus of blockchain technology beyond the finance sector and explore it in various other domains. [ABSTRACT FROM AUTHOR]

In this study, the financial performance of the firms in the Borsa Istanbul technology index is evaluated with TOPSIS and MABAC methods. The financial performance analysis of technology companies, which differ from other sector companies in terms of the return on investments and high borrowing levels, was carried out covering the years 2019-2022, and the weights of the financial ratios considered as evaluation criteria were obtained by the CRITIC method, which is an objective weighting method. As a result of the analysis, Papıl and Ard Group had the highest value in different methods and years, while Netaş had the lowest value. Escom and Kfeın were the companies with the highest fluctuations in the rankings over the years. [ABSTRACT FROM AUTHOR]

All elements in the supply chain, from the field to the delivery of fresh fruits and vegetables to the consumer, are of great importance to humanity. Different decision makers occur in the supply chain of delivering fresh fruits and vegetables to consumers in our country and the world. Considering the situation in our country, there are steps to deliver the products from the field to the wholesale markets, from the wholesale markets to the markets/grocers and from the markets/grocers to the consumers in the process from the production to the consumer. In this study, the wholesale markets brokers, market/grocery managers and consumers who have a say in the supply of fresh fruit and vegetable products, product selection approaches in the fields, selection approaches in wholesale markets and selection approaches in the grocery stores were investigated, respectively. It is aimed to determine the most important criteria in the supplier selection for each supply channel examined. Within the scope of the study, the wholesale markets brokers in the province of Denizli, domestic and national markets operating in the province and consumers living in different regions in the province are evaluated on quality, price, delivery, service, main product criteria and sub -expansions of these main criteria. AHP and TOPSIS methods were used to find important criteria in the election decisions of the suppliers at different levels, to select the most appropriate supplier and to compare the results. When the results obtained are examined, it is seen that the perspectives of the decision-makers other than consumers in the fresh fruit and vegetable supply chain are far from consumer expectations.

The cable industry carries out production with high raw material costs. Extruder lines make a difference in terms of product quality and costs. Therefore, the selection of the best line is important. In this study, four extruder lines were considered for a cable company for the production of a new insulation material. A total of seven evaluation criteria were determined for all alternatives. The decision-making group, consisting of production managers of the company, evaluated all alternatives under the criteria using linguistic expressions defined in Pythagorean fuzzy and triangular fuzzy number sets. As a result of the evaluations, objective criterion weights were determined using the Fuzzy CRITIC method with Pythagorean fuzzy numbers, and then the extruder line selection was carried out using the Fuzzy MAIRCA method with triangular fuzzy numbers. Sensitivity analyses were conducted to measure the impact of criteria on the obtained results. In the step of weighting the criteria, the energy usage criterion stood out. It was determined that the "Bobin" line is the most suitable for the conversion of the HFFR product into the final product. The study identified the priority line for the company where the application was carried out. [ABSTRACT FROM AUTHOR]

The concept of decision making is the process of choosing one of the available alternatives to achieve the goals and objectives. The problems that are frequently encountered today and that require evaluation of many criteria together are selection problems. Multi-criteria decision-making techniques offer suitable solutions to these selection problems. In this study, CRITIC integrated TOPSIS Method was used to determine which University Hospitals in Türkiye are closest to the ideal. In order to select the most suitable University Hospital in study, the most ideal solution was tried to be determined by considering 13 (thirteen) criteria. The criteria used in the study were first weighted with the CRITIC method, and then these weight values were used when ranking the University Hospitals with the TOPSIS method. Thus, it was aimed to determine the University Hospitals closest to the ideal by weighting the criteria. The intended meaning is for hospitals to be ranked at the top according to the assigned criterion weights. As a result of the study, the most ideal University Hospital was U18 (Erciyes University). Then, the University Hospitals are listed as U17 (Ege University Hospital) and U19 (Hacettepe University Hospital), respectively. University Hospitals that are not close to the ideal are U7 (Bozok University Hospital), U8 (Kafkas University Hospital) and U16 (Duzce University Hospital), respectively. [ABSTRACT FROM AUTHOR]

The balance of payments is defined as systematic and statistical tables that record a country's financial transactions with the rest of the world, influencing the economic performance of both developed and developing countries. Transportation activities are in a very important position in order to continue the exchange of goods and services in the international arena without any disruption, one of the main factors affecting the development of the world economy. In this study, the income and expenditure items related to transportation activities in Türkiye's balance of payments between 2012 and 2021 were analyzed using the CRITIC, ARAS and WASPAS techniques, which are Multi-Criteria Decision-Making Methods. According to the CRITIC Analysis, the criterion with the highest level of significance in measuring the performance of transportation activities in Türkiye's balance of payments was passenger expenditures (0.2167), while the criterion with the least significance was freight income (0.1328). The CRITIC, ARAS and WASPAS Analyses revealed that the year 2013 had the highest performance, while the year 2012 had the lowest performance in the 10-year performance ranking of transportation activities in Türkiye's balance of payments.

Supplier selection can be shown as one of the most critical decision-making processes for businesses today. When the literature on Multi-Criteria Decision Making (MCDM) Methods is examined, it is seen that there are many different methods from traditional methods to modern methods. With the help of these methods, it becomes possible for decision makers to choose between different alternatives by using different measurement units and criteria. However, different methods may produce different results due to details such as the different structures of these methods and the characteristics of the data sets. With this study, it is aimed to compare and evaluate together the results obtained through different MCDM methods as ARAS and EDAS on the same data set. When the results obtained are evaluated, it has been determined that the final rankings obtained from the two methods differ, 3 suppliers are in the same order in both methods, and the other 5 suppliers are in different rankings. In addition, it is seen that different suppliers are in the best supplier position in the two methods used. [ABSTRACT FROM AUTHOR]

The construction of the railway, which is needed for the development of the Eastern Black Sea Region, is an issue that has been discussed and unresolved for about 110 years. The geomorphological structure of the region and the developments in the highway played a role in the delay of the railway construction. However, the developing technology in the railway, Turkey's being a part of the Iron Silk Road Project, and the agreements made with international connections have brought the railway construction to the region again. In the Environmental Plan (EP) approved and in force by the Ministry of Environment, Urbanization and Climate Change, four railway routes are planned to integrate the Eastern Black Sea region with the national/international railway network. These routes are; Samsun-Sarp, Trabzon-Erzincan, Of-Erzurum and Tirebolu-Bayburt. However, some of these routes are alternatives to each other and are not feasible and rational since the implementation of all planned routes requires great costs. The aim of this study is to develop a method for prioritizing and selecting the railway routes planned in the EP. Within the scope of this purpose, by using Analytical Hierarchy Process (AHP) and TOPSIS techniques, which are multi-criteria decision making methods, the routes were listed according to 4 criteria and 10 sub-criteria determined with the help of literature and expert team. As a result of the study; In both techniques, the order was the same and it was determined that the Samsun-Sarp railway was the most priority railway route. Trabzon-Erzincan came second, Of-Erzurum came third and Tirebolu-Bayburt came fourth. [ABSTRACT FROM AUTHOR]

In recent years, expectations from internal audit have changed with globalization, diversification of risks, technological innovations and developments, international standards and legal regulations. Within the framework of both legal regulations and international internal audit standards, it has emerged that internal audit activities should integrate a risk-based perspective into internal audit processes rather than the traditional perspective. While this situation affects all internal audit units operating in different sectors, it has affected the internal audit units of banks, which are mandatory units for banks in Turkey, relatively more. The first stage of the risk-based perspective in internal audit is the planning of the areas to be audited through the risk assessments carried out objectively by the internal audit units. However, there are some difficulties as there is no method for objective risk assessment in practice. For this purpose, in this study, an application has been proposed on how a bank's internal audit unit can objectively prioritize the branches that should be audited, based on an imaginary example. In the proposed application, criteria for the branches to be prioritized in the annual internal audit plan were defined and scored, their weights were calculated with the standard deviation method, and the prioritization rankings for the branches were carried out using the ARAS method.

Amaç: Çalışmanın temel amacı, tatmin seviyesi tayin edilmemiş EATWOS ve OCRA yöntemlerinin verimlilik ölçümlerinde kullanılabilirliğini karşılaştırmalı olarak araştırmak ve söz konusu yöntemler arasındaki farklılıkları sağlık turizmi üzerinden sunmaktır. Yöntem: Bu çalışmada verimlilik ölçümü için tatmin seviyesi tayin edilmemiş EATWOS ve OCRA yöntemleri kullanılmıştır. İlk olarak araştırma problemine uygun olarak girdiler ve çıktılar belirlenmiş ve ENTROPI yöntemi kullanılarak ağırlıklandırılmışlardır. 2006-2019 yılları arasında Türkiye’deki sağlık turizm hizmetlerinin verimliliği ENTROPI+tatimin seviyesi tayin edilmemiş EATWOS ve ENTROPI+OCRA yöntemleri kullanılarak ölçülmüştür. Ardından, söz konusu yöntemlerle elde edilen sonuçlar karşılaştırılmış ve yorumlanmıştır. Bulgular: Bulgular, tatmin seviyesi tayin edilmemiş EATWOS yönteminin bir üretim biriminin verimli çalışıp çalışmadığını belirlemek için daha uygun bir yöntem olduğunu göstermiştir. Bunun aksine, OCRA yöntemi, üretim birimlerinin verimlilik ve performanslarına göre bir sıralama elde edilmesi istenen durumlar için daha uygundur. OCRA yöntemiyle elde edilen indeks değeri, bir üretim biriminin gerçekten verimli veya verimsiz olduğunu göstermemektedir. Bu indeks değeri, sadece, üretim biriminin sıralamadaki yerini göstermektedir. Özgünlük: Bu çalışma, tatmin seviyesi tayin edilmemiş EATWOS ve OCRA yöntemlerinin sağlık turizm hizmetlerinin verimliliğinin ölçülmesi için kullanılan ilk çalışma olarak gözükmektedir.

Bu çalışmanın amacı, G-20 Ülkelerinin Positive Money araştırma organizasyonu tarafından oluşturulan Yeşil Merkez Bankacılığı verileri ile sıralamasını yapmaktır. Yeşil Merkez Bankacılığı kapsamında G-20 ülkelerinin iklim ile mücadele için dört kategoride bilgileri toplanarak her ülke için karne puanı oluşturulmaktadır. Bu kategoriler “Araştırma ve Savunuculuk”, “Para Politikası”, “Finans Politikası” ve “Örnek Liderlik”tir. Çalışmada G-20 ülkelerinin Yeşil Merkez Bankacılık performansları bu kategorilerle değerlendirilmektedir. Analiz için Çok Kriterli Karar Verme yöntemlerinden biri olan PSI yöntemi tercih edilmiştir. PSI yöntemi birçok alternatif ve kriteri eş zamanlı analiz ederek çözüme ulaştıran yöntemlerden biridir. Analiz sonuçlarına göre ilk iki sırada, Fransa ve Brezilya çıkmıştır. İlk sıralarda çıkan ülkelerin merkez bankalarının iklim değişikliği konusunda daha hassas ve aktif oldukları görülmektedir. Sonuç olarak G-20 ülkeleri merkez bankalarının iklim değişikliğiyle faaliyet boyutları belirlenmektedir. Bununla birlikte çalışmada G-20 ülkelerinin merkez bankalarının iklim değişikliği konusunda ne kadar aktif olduğu ve diğer ülkeler içerisinde hangi konumda olduğu belirlenerek farkındalık oluşturulmak istenmiştir.

The taxes on which all states generate their income are levied on the income or assets of the citizens. These taxes collected from the citizens are used in line with public needs, and it is desired to be collected on a voluntary basis with the expectation of full compliance with the tax. In this context, in this study, it is aimed to analyze the importance of the factors affecting tax compliance and the relations between them by the DEMATEL method by taking the opinions of experts working in Kütahya Revenue Office. 20 expert working in Kütahya Revenue Office were included in the study. As a result of the study, it was seen that the most important main factor was "Economic Factors", while the least important factor was "Factors Related to the Tax System". In addition, while “Psychological Factors” and “Factors Related to the Tax System” were determined as influencing factors, the affected factors were Economic, Political, Social and Demographic factors. While "Economic Factors" was the factor with the most impact on the other four factors, "Factors Related to the Tax System" were determined as the most affected factors. [ABSTRACT FROM AUTHOR]
