The research was performed between customers from Turkey and Georgia. ServQual scale was conducted to obtain the data and evaluated using SPSS. Regression analysis was performed in order to see the impact of dimensions on the satisfaction and loyalty. Furthermore, Independent Samples T Test was performed to see which country was more satisfied about internet service provision than one another.

Elaborating Determinants of Location Strategy: A Case Study in Sulaymaniyah, Kurdistan Region of Iraq, 2020

Yet a significant number of them fail in making efficient footprints that slows down their progress in the long-term. Making decisions on location strategy is thought as risky as it affects flexibility, labor availability, changes in costs, and tax regulations. In this respect, the current paper provides insight to discuss how location affects the effectiveness of a company. Based on the results, it was seen that location costs were the determinant which impacted the revenues of the GSM card sales significant at P<0.01. Secondly, traffic crowdedness, popularity of the location, crowdedness of the location, accessibility, and popularity of the neighbor shops were the other significant determinants which effected the shop GSM card revenues at P<0.05, respectively. Besides, it was observed that free parking, crowdedness of shop, and distance from the center are not the significant determinants of the revenues of the shops from the GSM card sales.

To do this, we developed the list of main and sub-criteria from the current literature for evaluation of experts in the market of the Kurdistan region of Iraq. The experts evaluated and rated each main and sub-criteria with utmost care. The results were evaluated using the Analytic Hierarchy Process (AHP) methodology. The study explored the importance weights for each sub-criteria of the retail shop selection, which could be used for the practitioners when one evaluates the alternative locations to open a shop.

For this purpose, authors have discussed issue with the experts of this field and explored 7 dimensions such as communication, data transfer, features, aesthetics, security, feedback, and marketing. The survey questionnaire was asked to 1012 people who have been utilizing the one of the Instant Messaging Applications in Turkey. 620 of the data were ready to be used for analysis and remaining data was not used due to the reliability issues. Explanatory factor analysis was conducted to elaborate the dimensions and reliability analysis was conducted in order to check the reliability of the questionnaire. Finally, Structural Equation Modeling (SEM) was conducted to see how those dimensions effected the satisfaction of the customers. It was seen that all of those seven dimensions had significant effect on customer satisfaction of the Instant Messaging applications. However, those dimensions explained 60% of the total variance of satisfaction.

Bu anlamda SERVPERF ölçeğini GSM ve internet hizmet sektörüne uygun bir şekilde düzenleyerek uygulamak suretiyle veri toplanmış ve toplanan bu veri Yapısal Eşitlik Modeli yöntemiyle incelenerek hipotezler test edilmiştir. Ortaya çıkan analiz sonuçlarına göre GSM ve internet sektöründe her beş boyutun hizmet kalitesini anlamlı bir şekilde etkilediği yeterli kanıtla desteklenmiştir. Her iki sektör incelendiğinde, hizmet kalitesindeki bir birimlik yapılan iyileştirmenin müşteri memnuniyetine GSM sektöründe 0,86 ve internet sektöründe ise 0,93 birimlik etki ettiği görülmüştür. Ayrıca, bağımlı ve bağımsız değişkenler arası anlamlı farklılıkları ortaya koymak adına ilgileşim ve ANOVA testleri uygulanmıştır. Abstract The aim of this research is to investigate the effect of the five dimensions of service quality on customer satisfaction in a multisectoral area. In this manner the data has been collected by reorganizing and applying the SERVPERF scale for GSM and internet service sectors. Collected data has been used to test the hypthesis using Structural Equation Modeling. Test results clearly indicated that all five dimentions have meaningful effect on service quality in both GSM and internet sectors. Results also show that in case of one unit increase on the service quality has 0,86 unit effect on GSM customer satifcation and 0,93 unit effect on Internet customer satısfaction. Moreover, correlation and ANOVA tests were proposed in order to elaborate the significant differences between dependent and idependent variables.

In this concept, researchers conducted a survey questionnaire that was adopted from the research of Parasuraman et al.’s ServQual. Regression analysis has been proposed in order to see the significance of each dimensions of service quality on satisfaction. Later on the same model has been applied to see the significance of satisfaction on loyalty. Furthermore, the effect of loyalty and satisfaction on willingness to pay more was also tested by regression analysis model. Analysis of variance model had been conducted to see if there is any significant difference between demographic information (monthly spending, GSM operators, and age of the customers) and evaluation of dimensions of the service quality. The results show that responsiveness, reliability, and tangibles have significant effect on the satisfaction of the customers. It also has been seen that satisfaction has significant effect on the customer loyalty and both (satisfaction and customer loyalty) have significant impact on the willingness to pay more for GSM operators.

In this case efficiency plays a strategic role. On the other hand, customer satisfaction also must be considered when optimizing the human resources capacity. In this research, human resources capacity of a call center was calculated regarding to arrival of calls to the center and optimized by using waiting lines method. As a result it was seen that queuing theory worked and efficiency of the call center was increased

Furthermore, researchers compared countries from the satisfaction, loyalty, and willingness to pay more points. However, impact of satisfaction and loyalty on willingness to pay more was also tested in this research cross-nationally. Finally, countries were put in order from the satisfaction and loyalty points of view. To do these, regression analysis and ANOVA were proposed. As a result it was observed that both loyalty and satisfaction effect willingness to pay more in all countries those were included in this research. However, Iraq was the most satisfied country from the GSM service provision point. Georgia and Turkey didn’t have significant difference from the satisfaction point of view. Moreover, Iraq was more loyal to the GSM service companies rather than Turkey and Georgia.

However, many researches show that ANN models provide better optimum results than other competitive models in most of the researches. But does it provide optimum solutions in case ANN is proposed as hybrid model? The answer of this question is given in this research by using these models on modelling a forecast for GDP growth of Japan. Multiple regression models utilized as competitive models versus hybrid ANN (ANN + multiple regression models). Results have shown that hybrid model gives better responds than multiple regression models. However, variables, which were significantly affecting GDP growth, were determined and some of the variables, which were assumed to be affecting GDP growth of Japan,were eliminated statistically.
