  • An Evaluation of Supermarkets from the Lens of Multiple Criteria: The
           Intuitionistic Fuzzy TOPSIS Method

    • Authors: Feride TUĞRUL
      Abstract: This study is an attempt to evaluate supermarkets by both the consumer and the market researcher through the intuitionistic fuzzy TOPSIS. In this regard, the decision makers' views were expressed in linguistic terms and ranked from the most preferred supermarket to the least preferred supermarket. The satisfaction of using linguistic terms is that it gives decision makers the chance to express views that they cannot express in numerical values. Furthermore, undecided situations were interpreted through the IFS. This method, which may be easily used in many application areas, offers researchers more consistent results than the others due to its advantages. Besides, this study attempts to innovative implementation of the intuitionistic fuzzy TOPSIS method on its algorithm and mathematical basis.

  • Using Real Options in Wind Power Plant Evaluation

    • Authors: Duygu BIYIKLI; Faik Ahmet SESLİ, Pelin KASAP
      Abstract: The selection of the valuation method is one of the most important decisions in the valuation of large-budget investment projects such as the Wind Power Plant (WPP). The fact that traditional valuation methods do not take risks and uncertainties into account during the economic life of the investment and do not offer flexible solutions such as expansion, abandonment or postponement against possible situations in any period creates negative situations in applications. Real options enable the risk and uncertainty in the investment to be handled by using various analytical methods or simulations through probability distribution. Considering that the investment started in June 2021, pre-feasibility reports prepared beforehand were used in this regard, and the project parameters were determined considering the market values. Firstly, Net Present Value (NPV) was obtained by using the Discounted Cash Flows (DNA) method, which is one of the traditional valuation methods, for this WPP, which has a 5 MW electricity generation capacity, a capacity factor of 35% and an economic life of 15 years in the province of Sinop. are the most commonly used methods in the literature. Secondly, in the real options valuation process, the Black-Scholes valuation method, one of the analytical methods, used the option value and the Extended Net Present Value (GNPV) to evaluate whether the project is viable or not. In order for the investment project to be viable, the NPV obtained by the valuation method used must yield positive results and the investor must have earned a profit at the end of its economic life. The project is not viable for an investment with a negative result. The aim of the valuation study for RES was that while the project could not get the applicable approval with the negative result with NPV, the project was able to get the applicable approval with the real options by incorporating the risk and uncertainty into the project. In this case, although the superiority of real options over traditional methods has been demonstrated, it has also been concluded that traditional methods should be replaced by real options in practice.

  • Performance Comparison of K-Means and DBSCAN Methods for Airline Customer
           Segmentation

    • Authors: Kevser ŞAHİNBAŞ
      Abstract: Organizations are now fully embracing ideas such as customer success, customer loyalty, customer experience management and customer satisfaction. The application of these concepts must be based on three pillars of technology, process and people, to ensure that the organization ultimately has satisfied, loyal and successful customers. In today's competitive environment, as in all sectors, gaining great services in the aviation industry can provide a competitive advantage. With this study, it is aimed to help aviation companies to know how their services should meet the needs of customers and to obtain passenger satisfaction. Customer segmentation is widely used, which groups objects according to the similarity difference on each object and provides a high level of homogeneity in the same cluster or a high level of heterogeneity between each group. The aim of this study is to examine airline passenger satisfaction by using data mining methods including K-Means and Density-based spatial clustering of applications with noise (DBSCAN) clustering algorithms to reveal the service quality importance for customer satisfaction. K-Means algorithm achieved slightly better results than DBSCAN algorithm with a Silhouette value of 0.1450671.

  • Yorùbá Character Recognition System Using Convolutional
           Recurrent Neural Network

    • Authors: Jumoke AJAO; Shakirat YUSUFF, Abdulazeez AJAO
      Abstract: Handwritten recognition systems enable automatic recognition of human handwritings, thereby increasing human-computer interaction. Despite enormous efforts in handwritten recognition, little progress has been made due to the variability of human handwriting, which presents numerous difficulties for machines to recognize. It was discovered that while tremendous progress has been made in handwritten recognition of English and Arabic languages, very little work has been done on Yorùbá handwritten characters. Those few works, in turn, made use of Hidden Markov Model (HMM), Support Vector Machine (SVM), Bayes theorem, and decision tree algorithms. To integrate and save one of Nigeria's indigenous languages from extinction, as well as to make Yorùbá documents accessible and available in the digital world, this research work was undertaken. The research presents a convolutional recurrent neural network (CRNN) for the recognition of Yorùbá handwritten characters. Data were collected from students of Kwara State University who were literate Yorùbá writers. The collected data were subjected to some level of preprocessing such as grayscale, binarization, and normalization in order to remove perturbations introduced during the digitization process. The convolutional recurrent neural network model was trained using the preprocessed images. The evaluation was conducted using the acquired Yorùbá characters, 87.5% of the acquired images were used for the training while 12.5% were used to evaluate the developed system. As there is currently no publicly available database of Yorùbá characters for validating Yorùbá recognition systems. The resulting recognition accuracy was 87.2% while the characters with under dot and diacritic signs has low recognition accuracy.

  • Use of Generalized Additive Models in Animal Science

    • Authors: Nursen KURDAL; Hasan ÖNDER
      Abstract: Regression analysis is one of the most frequently used statistical methods in the field of animal science, as it is in many branches of science. However, it is not possible to provide linear regression assumptions for many biological studies. It is known that especially in cases where discrete data should be used as explanatory variables, the models obtained using linear regression can produce statistically incorrect results. For such cases, it is recommended to use non-parametric or semi-parametric methods instead of linear regression. In this study, it is aimed to introduce the generalized additive models proposed in the presence of discrete explanatory variables, using a dataset obtained from the field of animal science (n=166). While lactation milk yield was used as the outcome variable, lactation period and maternal age taken from dairy goat were used as explanatory variables. It was determined that the variables of lactation milk yield, lactation period and maternal age did not show normal distribution. It was determined that the obtained linear regression model was statistically significant (P0.05), the variables were not normally distributed. In this case, it can be said to recommend to use of generalized additive models. As a result, it has been determined that when it is necessary to create a model with discrete variables in animal science studies, using generalized additive models instead of linear models can be recommended as it will increase the reliability of the model to be obtained.
