PurposeService quality is an evaluation of how well a delivered service meets customers’ expectations. The purpose of this paper is to provide a reliable scale of measurement for service quality in banks.Design/methodology/approachThe SERVQUAL model was adopted based on a Banking Service Quality (BSQ) model and a two-phase multiobjective optimization model was designed. A structured questionnaire with five-point Likert scale was administered with a 93 percent response rate of 270 sample size. A total of 22 variables were considered based on the BSQ model and the significance of these variables to customers’ satisfaction were investigated. Factor analysis was used to extract the most influential factors on the measure of service quality and four factors were selected namely: they deliver when promised, precision on account statements, queues that move rapidly and sufficient number of ATMs per branch. In order to determine the reliability of the multiple Likert questions in the survey, Cronbach’sαwas used indicating a scale reliability of 0.743. Moreover, multiple regression analysis was carried out on the selected factors to design an objective function for the design and evaluation of service quality model. The model design used for benchmarking was done using multiobjective genetic algorithm in MATLAB. Similarly, the model evaluation was done in a java interface using multiobjective particle swamp optimization.FindingsThe evaluation results validated the designed model and showed that the factors they deliver when promised and queues that move rapidly are a more reliable scale of measurement for customer’s satisfaction than the factors precision on account statements and sufficient number of ATMs per branch.Research limitations/implicationsThe implication of the results is that effectiveness and assurance combined with access is a more significant factor for measuring customers’ satisfaction than tangibles based on the BSQ model.Originality/valueThe introduction of a two-phase optimization model for model benchmarking and evaluation as compared to ordinary factor analysis of the dimension constructs.

Purpose The purpose of this paper is to promote and analytically verify an advanced assessment design to evaluate service quality (SQ) especially in postgraduate higher education. Design/methodology/approach This research adopts a quantitative approach through a survey method. A structured questionnaire was designed as a means for collecting data. Data were collected from 182 postgraduate students in an Egyptian higher education university. Data were examined by exploratory factor analysis to pinpoint the main irregularities explained by the extracted factors. Then, confirmatory factor analysis was carried out to filter the ratios and empirically test the assessment efficiency of the developed model. Findings The final model consists of 33 items loaded into eight dimensions for measuring performance-based SQ of the postgraduate higher education. The results are satisfactory in terms of unidimensionality, trustworthiness, and validity tests. Research limitations/implications Although the empirical results are significant, a comparative study can identify relative strengths and weaknesses of this model. Practical implications For improving postgraduate higher education institutions’ quality, this paper highlights some dimensions and attributes that should be considered. Originality/value The literature proposes that there is an opportunity to handle SQ from the point of view of postgraduate students covering different contexts to further build a more comprehensive structure specifically for postgraduate higher education SQ. This paper deals with this research gap with analytical confirmation within the context of postgraduate programs in an Egyptian university.

Purpose – This paper aims to identify the gaps and differences between customer expectations and perceptions on service quality of Islamic banks in Malaysia based on six dimensions of service quality, namely, reliability, responsiveness, assurance, empathy, tangibles and Islamic Shari’ah compliance. Design/methodology/approach – This study surveyed 179 customers who have first-hand experience with Islamic banking services in Malaysia. The research data were analysed using reliability analysis, independent samples t-test and one-way analysis of variance. Findings – The results indicated that customers’ perceptions failed to meet their expectations on the service quality of Islamic banks in Malaysia. The results also indicated that those customers (respondents) aged below 30 years have higher expectations on empathy from the Islamic banking service compared to other age groups. However, there is no significant difference between customer expectations and perceptions of Islamic banking service quality based on educational background and occupation. Research limitations/implications – This research focused solely on Islamic banks in Malaysia and thus the results might not be applicable for other conventional banks. Originality/value – The findings are expected to provide guidelines for enhancing the satisfaction level of clients of the Islamic banking system in Malaysia and other countries.

Purpose This study aims to develop a comprehensive LOHAS (lifestyles of health and sustainability) restaurant service quality scale by using a rigorous qualitative and quantitative research process to effectively measure the service quality of LOHAS restaurants. Moreover, this study aims to further identify the Kano quality characteristics and strategic meanings of service attributes in LOHAS restaurants. Design/methodology/approach This study designed the preliminary items of the service quality scale for LOHAS restaurants (LORSERV scale) based on relevant literatures and expert interview procedures. This study identified the goodness of fit of the questionnaire content, construct validity and validity of the LORSERV scale using exploratory factor analysis and confirmatory factor analysis. The moderated regression was conducted to identify the Kano quality characteristics and strategic meanings of each service attribute in LOHAS restaurants. Findings The results indicated that the LORSERV scale included seven dimensions (internal sense of happiness, transitiveness, environment, healthy catering, service commitment, green practicability and thoughtfulness), for a total of 33 items. According to the results of the Kano model, the seven service attributes were categorized into the attractive quality. A total of 25 service attributes were categorized into the one-dimensional quality, and one service attribute was categorized into the must-be quality. Originality/value The contribution of this study is that the scale could facilitate operators of LOHAS restaurants to effectively understand customer perceptions of service quality and serve as a reference to upgrade and improve service quality. The identification of Kano quality characteristics for each service attribute is conducive for LOHAS restaurants to understand the strategic meanings of each service attribute and can serve as a reference to make distinctive service strategies to reach sustainable operations.

Purpose The purpose of this paper is to evaluate the perceptions of Nigerian banking customers regarding customers’ evaluation of their banks service quality based on their banks actual performance on current banking service delivery. Design/methodology/approach A survey has been used to collect primary data and 1,245 usable questionnaires were used in the analysis. A conjoint analysis with stated preference data were used to construct the consumers’ behavior, while discrete choice method was employed to evaluate the preferences. More information was obtained by in cooperating heterogeneity into the model by the random coefficient and the test variance with the primary attributes and social demographics and individual characteristics. Findings Discrete choice analysis shows that bank management should focus on: reduction of transaction errors, transaction cost, waiting time and initial online learning time. This four attributes have strong impact on customer’s satisfaction depending on quality performance. Relative to other services the reduction in waiting time and transaction cost are the most important services to the Nigerian banking customers. Other findings of willingness to pay and consumer preference for other attributes reveal more information for improved banking policies. Research limitations/implications The sample only focussed on the urban areas and did not consider rural dwellers. Future research should aim to improve on these by including a variable in the utility set up that captures the distance of the respondent to the main city. Practical implications Nigerian banking customers do not care about a friendly smile as customer care. Rather, they value more on the waiting time and transaction cost showing that convenience and cost dimensions have strong and direct effect on service quality. Other dimensions identified includes, reliability, product portfolio, security and privacy, ease of use, accessibility, and competence and credibility. Originality/value This study has drawn on a sample of 1,245 Nigerian banking customers and evaluating how the survey respondents perceive their respective banks’ performance by their evaluation of the current banking service delivery.

PurposeEducation plays a key role in socio-economic development and globalization has increased the numbers of students wanting to study abroad. Attracting international students is therefore an important objective for universities as international students open up opportunities to bring economic, cultural and academic benefits to both the universities themselves and to the countries in which they are located. This study therefore aimed to assess student satisfaction with a Jordanian university using the dimensions of quality contained within the established SERVQUAL model.Design/methodology/approachTo achieve these goals, quantitative data was collected from international students attending one university located in Jordan via a questionnaire survey, using a randomized sample. Structural equation modeling (SEM) was used to analyze the construct validity, and correlations between student satisfaction and the different dimensions of quality were tested.FindingsConsistent with other studies, the findings demonstrated that the five dimensions of service quality, i.e. tangibility, reliability, responsiveness, assurance and empathy, and the university of study, have a strong relationship with student satisfaction. However, there was no statistically significant correlation between country satisfaction and the tangibility and assurance sub-dimensions of quality.Practical implicationsPractical implications – The findings of this study are of interest and practical benefit to university leaders in developing their quality and student acquisition strategies.Originality/valueThis study makes a useful contribution to the growing body of evidence of service quality in higher education set within the context of a developing country.

Purpose The purpose of this paper is to present the development and implementation of a multiobjective optimization model and information system based on mobile technology, to support decision making in humanitarian logistics operations. Design/methodology/approach The trade-off between economic and social (deprivation) costs faced by governmental and nongovernmental organizations (NGOs) involved in humanitarian logistics operations is modeled through a Pareto frontier analysis, which is obtained from a multiobjective optimization model. Such analysis is supported on an information system based on mobile technology. Findings Results show useful managerial insights for decision-makers by considering both economic and social costs associated to humanitarian logistics operations. Such insights include the importance of timely and accurate information shared through mobile technology. Research limitations/implications This research presents a multiobjective approach that considers social costs, which are modeled through deprivation functions. The authors suggest that a future nonlinear approach be also considered, since there will be instances where the deprivation cost is a nonlinear function throughout time. Also, the model and information system developed may not be suitable for other humanitarian aid instances, considering the specific characteristics of the events considered on this research. Practical implications The inclusion of several types of goods, vehicles, collecting points off the ground, distributions points on the ground, available roads after a disaster took place, as well as volume and weight constraints faced under these scenarios, are considered. Social implications Deprivation costs faced by affected population after a disaster took place are considered, which supports decision making in governmental and NGOs involved in humanitarian logistics operations toward welfare of such affected population in developing countries. Originality/value A numerical illustration in the Latin American context is presented, the model and information system developed can be used in other developing countries or regions that face similar challenges toward humanitarian logistics operations.

PurposeThis study envisioned plausible influential factors on service quality and academic excellence relatable to graduate self-confidence in an open distance learning (ODL) outlook. The objective was to expose the moderating role of academic excellence (graduate satisfaction) between service quality and self-confidence (engagement, achievement, loyalty and opportunity, EALO). It was also of interest to explore how, in what routines factors involved interrelated.Design/methodology/approachThis study utilized exploratory design. Qualitatively, service quality included acclimation, advising, module, tutorial, assessment, feedback and referral factors. Service quality led to academic excellence (GPA, study length, relevance and recognition). Besides, academic excellence influenced self-confidence. Quantitatively, service quality, academic excellence and self-confidence were the independent, moderating and dependent variables. Respondents were randomly selected through a survey of eligible Universitas Terbuka alumni.Findings11 hypotheses were assessed under structural-equation modeling (SEM). Responses from 122 out of 500 graduates were completed. Eight hypotheses were validated by the analysis. The tutorial was the most influential factor followed by module, assessment and acclimation; advising, feedback and referral were excluded. Academic excellence also led to self-confidence. The study was able to visualize a substantial role of academic excellence in moderating service quality to EALO. Besides, important-performance analysis and customer-satisfaction index (IPA-CSI) recognized 21 out of 32 attributes as the pillars of academic excellence.Originality/valueThree of the hypotheses were invalidated by the quantitative analysis. Further inquiry with much broader coverage is then required to diminish the variance to finally find the ideal framework.
