    A comparative analysis of incremental and disruptive innovation policies in the european banking sector with hybrid interval type-2 fuzzy decision-making models
    (Springer, 2020) Dinçer, Hasan; Yüksel, Serhat; Martinez, Luis
    Nowadays innovation is a key issue in all business sectors, maintaining a positive correlation with the countries' economic development. The banking sector stands out among the different economic sectors, as globalization has pushed banks into tough competition. Hence, banks within this competitive framework must innovate by developing new products to be competitive and survive. The innovation in banking products is usually sorted as incremental or disruptive. Therefore, this paper aims to evaluate the innovation policies for the European Banking Sector by analyzing incremental and disruptive innovation policies. The novelty of the paper is to propose a set of dimensions and criteria for the innovation policies of European banking industry and to construct a hybrid decision-making model based on interval type-2 fuzzy sets. Accordingly, a comparative analysis of the top five GDP European countries has been carried out using a multiple criteria decision model (MCDM). The MCDM defines different criteria for incremental and disruptive innovations according to the specialized literature. Interval type-2 fuzzy DEMATEL (IT2 FDEMATEL) is used for weighting factors, and interval type-2 fuzzy VIKOR (IT2 FVIKOR) and interval type-2 fuzzy TOPSIS (IT2 FTOPSIS) are considered for ranking alternatives in the integrated modeling. Eventually, the findings highlight the most important criteria in this analysis and the results demonstrate that the comparative analysis of IT2 FVIKOR and IT2 FTOPSIS provides comprehensive and coherent results to select the best country in the innovation policies. In addition, the need to redesign the European banking system with necessary regulations to contribute to the development of the innovations is pointed out.

    A hybrid decision making approach for new service development process of renewable energy investment
    (Elsevier, 2023) Martinez, Luis; Dinçer, Hasan; Yüksel, Serhat
    This study aims at evaluating new service development (NSD) process of renewable energy in-vestments. A novel fuzzy hybrid multi-criteria decision-making model is then introduced. Firstly, selected criteria are weighted with a multi stepwise weight assessment ratio analysis (M-SWARA) methodology based on bipolar q-rung orthopair fuzzy sets (q-ROFSs) and golden cut. Secondly, balanced scorecard (BSC)-based project network for the NSD process of renewable energy investments is constructed. These alternatives are ranked by using the elimination and choice translating reality (ELECTRE) approach with bipolar q-ROFSs and golden cut. Afterwards, the Project Evaluation and Review Technique (PERT) diagram is developed by defining immediate predecessors based on the ranking results. Consequently, different paths are created to understand effective ways to generate NSD process. Our findings will show the crucial processes for the NSD process of renewable energy investments, and the PERT analysis will provide optimal paths to increase the performance of NSD process of the renewable energies. It is concluded that analysis is the most critical NSD process for clean energy investment projects. The findings indicate that the shortest path is defined as Path 2 with 48.6% of the total importance degree. On the other hand, the longest path is determined as Path 1 with 100%. Path 4 has the weakest importance with 65.2% in comparison to Path 3 with 83.4% with respect to the comparison same activity numbers. It is strongly recommended that both technical and financial aspects should be evaluated with necessary research while generating new products. This issue can have a positive contribution to the early solution of any potential problems.

    Analysis of balanced scorecard-based servqual criteria based on hesitant decision-making approaches
    (Pergamon-Elsevier Science Ltd, 2019) Dinçer, Hasan; Yüksel, Serhat; Martinez, Luis
    The measurement of quality of services has an important influence in the companies' competence, being even more relevant in the banking sector because of the high competition to keep and attract customers. Due to this fact, this paper proposes a balanced scorecard based SERVQUAL to rank competitors in the banking sector. The analysis will deal with hesitant fuzzy information that models the hesitancy of the experts involved. This analysis will be applied for weighting criteria and dimensions, ranking alternatives and different results that will define the Turkish banking sector. Its main goal is to show that banks should be more willing to help and support their customers to increase the quality of their services. Therefor the analysis aims at showing which is the most relevant factor in the balanced scorecard based-SERVQUAL dimensions according to the correlation coefficient? It also aims at providing a clear view about what type of actions should take banks to be closer to the customers. Additionally, it will be identified which is the importance of the different dimensions of the approach? Eventually the main conclusions obtained from the analysis will be detailed regarding the quality services offered by banks in Turkey and different recommendations will be elicited to increase the banks performance in service quality according to the criteria and dimensions emphasized in this study.

    Balanced scorecard-based analysis about European energy investment policies: A hybrid hesitant fuzzy decision-making approach with quality function deployment
    (Pergamon-Elsevier Science Ltd, 2019) Dinçer, Hasan; Yüksel, Serhat; Martinez, Luis
    This study aims at analyzing the performance results of the European policies in energy investment within an integrated multidimensional quality measurement approach. For this purpose, the quality function deployment is adopted to the multidimensional performance measurement based on the balanced scorecard method. The dimensions and criteria of customer and technical requirements, process design, and performance measurement are defined to measure each process of QFD (Quality Function Deployment) for the energy investment policies with the supported literature. Within this context, the customer and technical requirements for energy investment policies are evaluated by considering the fuzzy decision matrix in the first process of the QFD and then, the technical requirements are used to rank the new service/product process of the energy investments in the second process of QFD. The balanced scorecard perspectives and the key factors are defined to rank the European energy investment policies respectively. Accordingly, the possible priorities of the European energy investment policies are discussed to conduct the most remarkable and efficient energy operations and the relevant results to contribute the improvement of energy sector are highlighted.

    House of quality-based analysis of new service development using context free grammar evaluation-enhanced fuzzy hybrid modelling
    (IEEE - Institute of Electrical and Electronics Engineers, Inc, 2021) Dinçer, Hasan; Yüksel, Serhat; Martinez, Luis
    The purpose of this study is to analyze new service development competencies based on house of quality (HoQ) in the healthcare industry by using a hybrid interval-valued intuitionistic decision-making approach with fuzzy linguistic information modelled by hesitant fuzzy linguistic term sets (HFLTSs) and linguistic 2-tuples. The novelty of the manuscript is to identify a list of criteria, dimensions, and alternatives for HoQ-based new service development used for the investment decisions in healthcare industry. Thus, a hybrid model with HFLTSs has been proposed, considering 2-tuple linguistic information, Interval-Valued Intuitionistic Fuzzy Sets (IVIFSs) and a defuzzification process with an attitudinal expected score function. Hence, a DEMATEL extension dealing with HFLTSs, linguistic 2-tuple and IVIFS has been developed and used to weigh the criteria and dimensions of customer needs. Similarly, a TOPSIS extension dealing with the same type of information is introduced and applied in order to rank the technical requirements, the so- called "new service development competencies in healthcare industry". Thus, this study contributes to the literature of health economics and management by proposing an original methodology. It is identified that financial expectations play the most significant role for demanders of healthcare services. Hence, competitive pricing strategies should be generated to obtain consumer loyalty in the healthcare industry. Moreover, technological infrastructure is found as the best ranked technical requirement of new service development competencies.

    Interval type 2-based hybrid fuzzy evaluation of financial services in E7 economies with DEMATEL-ANP and MOORA methods
    (Elsevier Science Bv, 2019) Dinçer, Hasan; Yüksel, Serhat; Martinez, Luis
    The financial services are key instrument for the right evolution of economy, mainly in the emerging countries. Therefore, the evaluation of the financial services is crucial for the economic development of such a type of countries. Different methods have been applied to accomplish this service evaluation, but its complexity greatly involves uncertain information. Therefore, this paper aims at considering in a more comprehensive way the managing of such uncertainty by the use of interval type-2 fuzzy sets. Hence, it will be proposed a novel evaluation methodology based on a hybrid multi-criteria decision method integrating DEMATEL-ANP (DANP) and MOORA able to deal with interval type-2 fuzzy sets. For the robustness check, the TOPSIS and VIKOR based on interval type-2 fuzzy sets are compared with the MOORA method and the sensitivity analysis is also applied to analyze the consistency of decision makers' priorities. This novel hybrid methodology will be used to evaluate the financial service performance in the emerging seven (E7) economies to conclude what kind of strategic actions should be taken by governments to improve their financial systems as well as to identify a ranking regarding the financial service quality of the E7 economies.
