Abstract

Purpose

The purpose of this paper is to propose a novel approach based on utility mining for store layout.

Design/methodology/approach

A utility mining-based data mining algorithm is utilized in this paper.

Findings

A real-life case study in a supermarket is conducted to illustrate the proposed approach. The findings show that the proposed approach can be used easily and efficiently to arrange store layout.

Research limitations/implications

There are two limitations to this study. First, space allocation to each product family is not considered. Second, product placement in each product family is not taken into account in the proposed approach.

Originality/value

In this paper, a novel approach is proposed for business intelligence in retail business. The proposed approach uses a utility-based data mining approach, namely, the high-utility itemset mining (HUIM) algorithm, to rearrange store layout and to determine the relations among product families. The quantities and prices of items purchased corresponding to product families are taken into account in the proposed approach to address the needs in practice. Business intelligence software is also developed as an integral part of the proposed approach to utilize the HUIM algorithm.

Abstract

Purpose

This study aims to propose a service quality evaluation model for health-care services.

Design/methodology/approach

In this study, a service quality evaluation model is proposed based on the service quality measurement (SERVQUAL) scale and machine learning algorithm. Primarily, items that affect the quality of service are determined based on the SERVQUAL scale. Subsequently, a service quality assessment model is generated to manage the resources that are allocated to improve the activities efficiently. Following this phase, a sample of classification model is conducted. Machine learning algorithms are used to establish the classification model.

Findings

The proposed evaluation model addresses the following questions: What are the potential impact levels of service quality dimensions on the quality of service practically? What should be prioritization among the service quality dimensions and Which dimensions of service quality should be improved primarily? A real-life case study in a public hospital is carried out to reveal how the proposed model works. The results that have been obtained from the case study show that the proposed model can be conducted easily in practice. It is also found that there is a remarkably high-service gap in the public hospital, in which the case study has been conducted, regarding the general physical conditions and food services.

Originality/value

The primary contribution of this study is threefold. The proposed evaluation model determines the impact levels of service quality dimensions on the service quality in practice. The proposed evaluation model prioritizes service quality dimensions in terms of their significance. The proposed evaluation model finds out the answer to the question of which service quality dimensions should be improved primarily?

Abstract

Purpose

The purpose of this study is to find the relationships among advanced manufacturing technology (AMT), innovation, export and firm performance by using data obtained from 310 Turkish manufacturing firms.

Design/methodology/approach

A survey study was performed to obtain data from manufacturing firms. Multiple-item scales were adapted from the literature to conduct the survey in this study. Data were collected from five cities located in the Southeastern Anatolia Region in Turkey (Gaziantep, Adiyaman, Kilis, Diyarbakir and Sanliurfa). Structural equation modeling was utilized to investigate the relationships among AMT, innovation, export and firm performance in Turkish manufacturing firms operating in several industries. The direct and indirect relations between these variables are examined in the proposed conceptual model. In addition, the complex relations including in the proposed model are assessed in detail through the mediation analysis.

Findings

Six of the proposed ten hypotheses related to manufacturers are validated by the empirical evidence from manufacturing companies in Turkey. Significant findings obtained in this study include the following: there are strong positive associations between the use of AMT and innovation and between export and firm performance. In addition, innovation mediates the relationship between AMT and firm performance and between AMT and export. Finally, export mediates the relationship between AMT and firm performance and between innovation and firm performance. It is expected that the results obtained from this empirical analysis will help decision makers and managers to construct a good technology and production management strategy for manufacturing systems.

Originality/value

In this study, a novel conceptual model is proposed to examine the relationships among AMT, innovation, export and firm performance via the use of survey responses from 310 Turkish manufacturing firms. To the authors’ best knowledge, this is the first study that proposes such a conceptual model in the literature.

Abstract

Purpose

The purpose of this study is to determine the relationships between technology transfer, innovation and firm performance.

Design/methodology/approach

The relationship between technology transfer, innovation and firm performance is examined by using data obtained from 252 Turkish export firms, which are among the top 1,000 firms in terms of export volume in Turkey. To examine these relationships, a theoretical framework is empirically tested using structural equation modeling and tested via an empirical study of Turkish export companies.

Findings

The results of this study can benefit policymakers in government at the national level and company decision-makers at the firm level. Furthermore, an understanding of the relationship between technology transfer, innovation and firm performance may help firms to make correct technology transfer decisions and focus on the correct type of innovation to increase firm performance in practice. The findings indicate the positive effects of technology transfer on innovation and firm performance. In addition, innovation mediates the relationship between technology transfer and firm performance in Turkish export companies. This study suggests that decision-makers should transfer the right technology because well-realized technology transfers lead to the improvement of corporate innovation capacities and improvement of firm performances for export companies.

Originality/value

There is no study that fully examined the relationship between technology transfer, innovation and firm performance. The proposed literature-based theoretical framework in this study is novel for Turkish export companies.

Abstract

Purpose

The purpose of this paper is to propose an innovative and integrated approach based on service quality measurement (SERVQUAL), quality function deployment (QFD) and failure modes and effects analysis (FMEA) for service quality improvement.

Design/methodology/approach

The SERVQUAL scale is used for service quality measurement, QFD is used for service design and FMEA is used to prevent possible failures during service delivery.

Findings

A case study in a public hospital in Turkey is performed to show how the proposed approach works in practice. The results of the study show that the proposed approach can be used effectively to assess service quality in practice.

Originality/value

Service quality has become an important issue for service enterprises facing a fiercely competitive environment to provide sustainability. This is the first study that applies an integrated methodology based on SERVQUAL scale, QFD and FMEA to service quality improvement.

Abstract

Purpose

The literature on corporate social responsibility (CSR) neglects the link between values and their ideological underpinnings. This paper aims to fill this void by grounding the managerial values towards CSR on an ideological ground by following the Schwartz’s (1994) value framework.

Design/methodology/approach

This paper provides a theoretical construct that builds the ideological stances of different managerial values towards CSR.

Findings

The study proposes that ideologically liberal managers might be involved in CSR based on their openness to change values, whereas their conservative counterparts are likely motivated by the conservative values such as security, conformity and tradition. On the other hand, egalitarian managers can engage in CSR based on their self-transcendence values, while non-egalitarian managers might involve in CSR based on their self-enhancement values as achievement and power.

Practical implications

The study can provide to all stakeholders a new perspective and a sound reference point to understand and monitor the socially responsible behaviours of managers.

Originality/value

The proposed bases of managerial values to CSR deepen the understanding on the antecedents of CSR. Based on the study, the future studies can configure out the role of diverse values on CSR in line with their ideological roots.
