      Piyathanavong, V., Garza-Reyes, J.A., Kumar, V., Maldonado-Guzman, G., Kumar Mangla, S.; University of Derby (Elsevier, 2019-02-19)
      Evidence suggests that manufacturing companies have tried to address the current environmental challenges derived from their operations by implementing various operational environmental sustainability approaches, including green manufacturing (GM), cleaner production (CP), green lean (GL), green supply chain management (GSCM), reverse logistics (RLs) and circular economy (CE). However, although their adoption is well documented in developed nations and few other countries, very little has been done to understand such phenomenon in a rapid developing country such as Thailand. This paper aims at filling this gap by providing light into some fundamental issues regarding the implementation of these approaches in the manufacturing sector of Thailand. A survey-based exploratory research was carried out based on 287 Thai manufacturing companies. The data was analysed using a combination of descriptive and inferential statics. The study revealed that a large amount of investment capacity, and proper training & knowledge are needed to fully implement the studied operational approaches. This resulted in some of the weakest elements of Thai manufacturing firms and hence the main barriers to their implementation. The study also showed that Thai manufacturing firms consider the impact on the environment and benefits from adopting these operational approaches as company’s policy and own initiative, environmental awareness, and cost saving from conservation of energy as the main reasons for adopting the studied operational approaches. Finally, the findings also indicate that Thai manufacturing firms tend to implement them because of internal factors and that they lack of motivation from external factors and involvement from other stakeholders. The paper extends the current limited knowledge on the deployment of operational environmental sustainability approaches in Asia, and its results can be beneficial for organisations that aim at effectively adopting them to improve their operation’s sustainability.
    • Aerospace industry in México and biofuels: a sustainability approach

      Rocha-Lona, L., Muñoz-Sanchez, C., Garza-Reyes, J.A., Kumar, V., Lopez-Torres, G.C.; University of Derby (ET Pub, 2019-03)
      The development of the aerospace industry in Mexico shows potential growth measured through the levels of state investment and the arrival of several international manufacturers to set up manufacturing production because of advantages offered by the country’s proximity to North America and its international trade agreements with the European Union and some Asian countries, which are considered to be the biggest markets in this sector. Very high demand is expected for jet fuels in the coming decades due to intense global economic activity. Under this context, the Mexican government has developed infrastructure and several programs aimed at developing sustainable longterm biofuels for the industry. The objective of this research is to provide a literature review of the aerospace industry and the main biofuel crops currently deployed for this industry (mainly transportation). The main results show a promising and innovative industry fostered by public and private investments motivated by Mexico’s recent regulatory changes in the energy sector. The main raw material crops for the production of biofuel in Mexico are Jatropha, sunflower, canola, and palm oils, all of which present significant advantages with production in Mexican soils. Important challenges remain, however, for continued development of capabilities in R&D, manufacturing production, supply chain optimization, and market development for biofuels.

      Maldonado-Guzman, G., Garza-Reyes, J.A., Solano-Romo, L.I.; University of Derby (IEOM Society, 2019-03)
      The prediction of the production of food is a very important topic that is attracting more the attention of researchers, scholars and professionals in the field of business and management since it is currently an issue at a global level considering the shortage of food and the exponential increase of the population. Similarly, the development of forecasting models about production are commonly used by different researchers and scholars to create predictions of the production systems, including good, as they normally provide valuable information for both making business decisions and reducing costs. For this reason, the main objective of this empirical research is the proposal of a forecast production model by applying a case study for a family agro-industrial enterprise from Aguascalientes (Mexico) through the implementation of a computer system that improves significantly their planning and commercial system of agro-industrial products (i.e. broccoli).

      Binti Aminuddin, Nur Ainunnazli; Garza-Reyes, Jose Arturo; Kumar, Vikas; Antony, Jiju; Rocha-Lona, Luis; University of Warwick; University of Derby; University of the West of England; University of Edinburgh; National Polytecnic Institute of Mexico (Taylor and Francis, 2015-06-15)
      To ensure manufacturing organisations remain competitive, most of them are turning to total productive maintenance (TPM) and lean manufacturing to ensure seamless operations. Overall equipment effectiveness (OEE) is the foundation of these two business improvement strategies as it tackles the underlying losses that impede equipment efficiency. This study presents the prevalence of managerial issues related to the implementation and use of OEE in the manufacturing industry. To do this, five hypotheses and four research questions were formulated and tested using a combination of descriptive statistics and cross-tabulation, chi-square, analysis of variance, Tukey’s pairwise comparison, Z-test and correlation tests. Data were collected through a survey questionnaire responded by 139 manufacturing organisations worldwide. The results establish, among other ‘soft’ aspects, the linkage of the OEE implementation with that of TPM and lean manufacturing, and the drivers, most critical factors, barriers and the role of management in its implementation. The study also identifies how manufacturing organisations employ the information provided by OEE and how the data for its computation are collected. This study supports the very limited empirical research on the implementation and use of OEE. Thus, this research provides organisations, and their managers, with a better understanding of different factors that affect the successful deployment and management of this highly used measure in industry.
    • Assessing systematic literature review bias: kaizen events in hospitals case study

      Gonzalez Aleu, Flores, F.F., Perez, J., Gonzalez, R., Garza-Reyes, J.A.; University of Derby (IEOM Society, 2020-04)
      A systematic literature review (SLR) is a protocol used to identify publications, select relevant publications, collect data, conduct scientometric analyses, and report research results (SLR outcomes or findings). Despite the increasing use of SLR to assess the maturity or evolution of a research field, as Engineering Management, there are a limit number of publications focused to test SLR biases. Therefore, the purposes of this investigation are to test search field bias (precise SLR vs. sensitive SLR) and to identify statistically significant differences between SLR outcomes. In order to achieve these goals, a three steps methodology was used in three platforms/databases. First, a precise SLR in ProQuest (search terms only in abstract) was conducted to identify publications describing a single Kaizen event in a hospital. From these publications, five metrics were assessed: new authors per year, number of authors per paper, number of publications per year, Kaizen event duration (days), and number of tools used during the Kaizen event per paper. Second, a sensitive SLR in ProQuest (search term in full text) was conducted using the same search terms, exclusion criteria, and metrics from the first step. Third, t-test hypotheses were conducted in SPSS version 20 to identify statistically significant difference for each metric between precise SLR vs. sensitive SLR. The same three steps were used in two more platforms/databases: EBSCOhost and Scopus. Initial results from this ongoing investigation show statistically significant differences between precise SLR and sensitive SLR for some of the five metrics assessed, such as the number of publications per year. Final results will be available in November 2018.

      Cherrafi, Anass; Elfezazi, Said; Garza-Reyes, Jose Arturo; Benhida, Khalid; Mokhlis, Ahmed; Cadi Ayyad University; University of Derby (Taylor and Francis, 2017)
      Green Lean has recently emerged as an alternative strategy for organizations to pursue both operational and sustainability excellence. The interest on this approach has rapidly risen in both academic and industry circles. However, despite this interest, very limited research has focused on its implementation, and no research has investigated the barriers that hinder the success of such activity. This study investigates the Green Lean implementation barriers and their contextual relationships and effects on the integration and deployment of this approach. A Systematic Literature Review (SLR), Interpretative Structural Modelling and fuzzy Matriced’ Impacts Croise’s Multiplication Appliqée a UN Classement (MICMAC) analyzes were carried out. Fifteen barriers were extracted from the SLR and then validated in consultation with industry and academic experts. The Interpretive Structural Modelling (ISM) method was used to understand the relationship between the fifteen barriers and to develop a hierarchical model of these. The different barriers were classified into ‘linkage’ and ‘dependent’ barriers by using MICMAC analysis. The results suggested that all the identified barriers play an important role, and hence can equally act as a significant hurdle to the implementation of Green Lean projects. This study can help managers and policy makers in better understanding these barriers. Thus, they can be assisted in managing and prioritizing barriers towards the successful implementation of Green Lean initiatives for better financial and environmental performance.
    • Barriers to innovation in service SMEs: Evidence from Mexico

      Maldonado-Guzman, Gonzalo; Garza-Reyes, Jose Arturo; Pinzon-Castro, Sandra Yesenia; Kumar, Vikas; The University of Derby (Emerald, 2017)
      Purpose – Specific research related to the study of innovation barriers in service SMEs in the Latin American region is limited. This study thus investigates the effects that external environmental, financial and human barriers have on innovation activities, particularly, within the context of Mexican service SMEs. Design/methodology/approach – Three hypotheses were formulated and tested using structural equation modelling (SEM). Data were collected through an instrument that was developed based on relevant constructs adapted from the literature. The instrument was validated using Confirmatory Factor Analysis, Cronbach’s alpha test and Composite Reliability Index to ensure the reliability of the theoretical model. The instrument was distributed among service SMEs in the Aguascalientes state of Mexico, from were 308 valid responses were obtained. Findings – In general, the results indicate that all of the three barriers investigated (i.e. external environmental, financial and human) hinder innovation in service SMEs, with the external environmental barrier being the most significant of the three. Practical implications – The findings of this research can inform managers of service SMEs and policy makers when formulating and implementing strategies to reduce innovation barriers. Originality/value – Evidence suggests that specific research related to the study of innovation barriers in service SMEs in the Latin American region is limited. This paper fills this research gap by expanding the limited body of knowledge in this field and providing further evidence on this phenomenon. The study also enables the distinctive characteristics of innovation barriers to be understood within a particular context, expanding in this way the body of knowledge on this field.
    • Behavioural factors on the adoption of sustainable supply chain practices

      Kumar, Anil; Moktadir, Md. Abdul; Rehman Khan, Syed Abdul; Garza-Reyes, Jose Arturo; Tyagi, Mrinal; Kazançoğlu, Yiğit; University of Derby; University of Dhaka, Bangladesh; Tsinghua University, Beijing, China; BML Munjal University, Gurgaon, India; et al. (Elsevier, 2020-02-05)
      Sustainable supply chain management (SSCM) has become a popular research topic among scholars as evidence suggests it has significantly contributed to achieve more environmentally conscious and socially responsible supply chains. Operational excellence (OE), on the other hand, can be achieved by incorporating SSCM practices within existing supply chain operations. However, due to human expertise, involvement and commitment towards excelling at sustainable and operational performance, the effective deployment of SSCM practices now depends on various humanbased behavioural factors (BFs). Human behaviour is dynamic in nature and hence has an effect on the implementation of SSCM practices. Nevertheless, research on BFs in view of SSCM practices is limited. To fill this knowledge gap, this study examines the nature of BFs for SSCM practices towards OE in supply chains, particularly within the context of the footwear industry of Bangladesh. In the first phase, the BFs were identified and determined through a literature review and empirical investigation. In the second phase, the Hesitant Fuzzy DEMATEL method was used to establish the cause-effect relationships among the factors. The influence of group validation by experts and a literature survey, along with managerial implications, was discussed and explained in the third phase of the study. The results suggest that the factor, 'organisation culture' is the most influencing behavioural factor, followed by 'commitment from higher authority'. Both theoretical and practical contributions of the study are drawn from its findings, helping footwear industry managers to more effectively adopt SSCM practices in the supply chain operations of their organisations to achieve OE.
    • Benchmarking of cleaner production in sand mould casting companies

      Guilherme da Silva, H; Espíndola Ferreira, J.C; Vikas, K; Garza-Reyes, J.A.; Universidade Federal de Santa Catarina, Florianópolis, Brazil; University of the West of England; University of Derby (Emerald, 2020-04-29)
      The purpose of this research was to develop new sustainability indicators consistent with the sand mould casting industry, through Benchmarking of Cleaner Production (CP), in order to identify the levels of practice and performance of companies of the casting sector. In addition, a lean manufacturing checklist was specified in order to verify the presence of lean manufacturing techniques employed to eliminate waste towards CP. No previous work was found in the literature that attempts to assess practices and performance of companies performing sand mould casting (a significantly polluting manufacturing process) in the context of cleaner production and lean manufacturing. For the application of this benchmarking, nine companies from the sand mould casting sector were studied, where the profile of each company was analysed through 8 variables and 47 indicators. Data were obtained through face-to-face visits and questionnaire application in the companies, and the data were analysed both quantitatively and qualitatively. The results obtained were the diagnosis of companies' practices and performance resulting from their position in the benchmarking charts, as well as the identification of the areas in which companies should implement improvements aiming at achieving CP. This research was developed specifically for sand mould casting companies, and each process has its own characteristics. 14 companies that perform sand mould casting were invited to participate in this survey, but unfortunately five companies declined to participate. It is important to diagnose casting companies regarding cleaner production practices, performance and deployment potential. Thus, important negative issues in the company can be identified and, with this information, they can develop actions focused on cases that need more attention. In addition, this work contributes to evaluate the relationship and efficiency of improvement actions developed by companies in the context of both lean manufacturing and cleaner production, aiming to reduce or eliminate the environmental impact. The improvement of practices and performance of a company regarding cleaner production is considered to be beneficial to supply chain management in the context of sustainability, as the other participating companies are likely to seek ways to reduce environmental impact, and the diagnostics provided by this work may also be used by those companies.
    • Best supply chain management practices and high- performance firms: the case of Gulf manufacturing firms.

      AL-Shboul, Moh’d Anwer; Garza-Reyes, Jose Arturo; Kumar, Vikas; University of Derby; German-Jordanian University; University of West of England (Emerald, 2018-10)
      Purpose – The study aims to investigate the best supply chain management practices that are implemented in medium and large-sized Gulf manufacturing firms. Design/methodology/approach – This study has explored seven supply chain management practices, i.e. supplier collaboration, flexibility with partners, usage of Internet, customer focus, lean production, Internal integration, and quality management. It assumes that the best performing firms must be the ones implementing the best practices. T-test and multiple linear regression analyses were used to establish the best practices, implemented by medium and large-sized Gulf manufacturing firms. Findings – The results showed that quality management, customer focus, and supplier collaboration are considered as best supply chain management practices in Gulf manufacturing firms. Usage of internet may have been the best practice previously, but not anymore. Lean production cannot yet be qualified as, but may develop into the best supply chain management practice. Practical Implications – The study provides a useful contribution to the field of best supply chain management practices as it provides better decision-making insights and a benchmarking base to top managers, policy makers, and academics. It is likely to result in increased overall performance of their firms. Originality/value – The study provides an understanding of the distinctive characteristics of the best supply chain management practices, implemented by Gulf manufacturing firms. It has broader implications for all manufacturing firms, particularly in developing economies where the growth of manufacturing and effective management of their supply chains is a key element for the economic development.

      Rocha-Lona, L.; Garza-Reyes, J.A.; Kumar, V.; University of Derby; University of the West of England (CRC Press, 2013-06-25)
      Quality has quickly become one of the most important decision-making factors for consumers. And although organizations invest considerable resources into building the right quality management systems (QMSs), in many instances, the adoption of such quality improvement tools are just not enough. Building Quality Management Systems: Selecting the Right Methods and Tools explains exactly what directors, practitioners, consultants, and researchers must do to make better choices in the design, implementation, and improvement of their QMSs. Based on the authors’ decades of industrial experience working on business improvement projects for multinationals looking to design or improve their QMSs, the book discusses building QMSs based on two important organizational elements: needs and resources. It begins with an overview of QMSs and systems thinking and the impact of QMSs on financial performance. Illustrating the process management approach, it reviews the most well-known business and quality improvement models, methods, and tools that support a major QMS. The authors introduce their own time-tested methodology for designing, implementing, and enhancing your own QMS. Using their proven method, you will learn how to: - Implement a strategic quality plan based on your specific needs, capabilities, cost–benefits, policies, and business strategies - Select the right models, methods, and tools to be adopted as part of your QMS - Understand the critical success factors and implementation challenges - Evaluate the level of maturity of your QMS and your implementation efforts Highlighting the importance of quality as a way of life, this book supplies the understanding you’ll need to make the right choices in the development and deployment of your QMS. With a clear focus on business performance and process management, it provides the basis for creating the quality management culture required to become a world-class organization.

      Trivedi, Shrawan Kumar; Dey, Shubhamoy; Kumar, Anil; Indian Institute of Management Sirmaur, Sirmaur, India; Indian Institute of Management Indore, Indore, India; University of Derby; Department of IT and Systems, Indian Institute of Management Sirmaur, Sirmaur, India; Department of Information Systems, Indian Institute of Management Indore, Indore, India; Department of Decision Science, BML Munjal University, Gurgaon, India (Emerald Insight, 2018-08-06)
      Sentiment analysis and opinion mining are emerging areas of research for analysing Web data and capturing users’ sentiments. This research aims to present sentiment analysis of an Indian movie review corpus using natural language processing and various machine learning classifiers. In this paper, a comparative study between three machine learning classifiers (Bayesian, naïve Bayesian and support vector machine [SVM]) was performed. All the classifiers were trained on the words/features of the corpus extracted, using five different feature selection algorithms (Chi-square, info-gain, gain ratio, one-R and relief-F [RF] attributes), and a comparative study was performed between them. The classifiers and feature selection approaches were evaluated using different metrics (F-value, false-positive [FP] rate and training time).The results of this study show that, for the maximum number of features, the RF feature selection approach was found to be the best, with better F-values, a low FP rate and less time needed to train the classifiers, whereas for the least number of features, one-R was better than RF. When the evaluation was performed for machine learning classifiers, SVM was found to be superior, although the Bayesian classifier was comparable with SVM. This is a novel research where Indian review data were collected and then a classification model for sentiment polarity (positive/negative) was constructed.
    • Causal modelling and analysis evaluation of online reputation management using Fuzzy Delphi and DEMATEL

      Kumar, Anil; Dash, Manoj Kumar; BML Munjal University; Indian Institute of Information Technology and Management, Gwalior; School of Management, BML Munjal University, Gurgaon, India; Behavioural Economics Experiments and Analytics Laboratory, Indian Institute of Information Technology and Management, Gwalior, India (IGI Global, 2017-01)
      Online reputation management (ORM) is a significant and proactive tool that can reinforce the credibility of the service provider. Literature existing today on this topic has rarely reported on the causal modeling analysis from an ORM perspective. Therefore, the objective of this paper is to build a factor structure of ORM and to build the inter-relationship map amongst the criteria of each factor. To allow for vague human judgment, a fuzzy concept is employed in a form of Fuzzy Delphi. The DEMATEL technique has been used to develop a Network Relationship Map (NRM) among the criteria of each factor. Data has been gathered through a structured questionnaire conducted with a survey of experts. The study divided the criteria of each factor into cause-effect criteria. Findings of the study show that criteria such as distributed reputation system, trust, online competitive branding, website management, customer relationship, search engine optimization, corporate social responsibility, users' reach, competition/page views, purchase discounted products and cash back or money back fall under the cause group of ORM's factors. The results of this study can not only help service providers to enhance their reputation but can also guide them towards targeting their customers in an online platform.
    • The challenges of GSCM implementation in the UK manufacturing SMEs.

      Kumar, Vikas; Sabri, Shahruzzaman; Garza-Reyes, Jose Arturo; Nadeem, Simon Peter; Kumari, Archana; Akkaranggoon, Supalak; University of the West of England; University of Warwick; Khon Kaen University; University of Derby (IEEE, 2019-01-31)
      The importance of green supply chain management has long attracted the interest of both researchers and practitioners in the industry. As environmental concerns are becoming one of the major issues discussed in the 21st century, countries with manufacturing as its principal economy contributor are always on the lookout for innovations and new approaches to balance both environmental considerations and profit making. The UK, being one of the top manufacturing countries in the world already considered green initiatives among their manufacturers. According to reports from the industry, large and international manufacturing companies from the UK have successfully implemented some green initiatives with significant improvements across the supply chain. However, the adoption of green initiatives is mainly focused on large companies rather the real backbone of the UK manufacturing industry, which is the small and medium-sized enterprises (SMEs). This paper therefore sets out to determine the implementation level of green supply chain among the SMEs. The paper adopts a mixed methods based approach and findings are based on 57 survey responses and 5 semi-structured interviews from UK manufacturing SMEs. The findings show that the level of GSCM implementation among the UK manufacturing SMEs is low compared to large organisations. Cost of implementing GSCM practices emerged as a key challenge faced by the UK manufacturing SMEs which was followed by the lack of knowledge within the organisation. This study thus adds to the limited literature on the manufacturing SMEs and provides evidence from the UK manufacturing sector on the adoption of GSCM practices.
    • The circular economy impact on small to medium enterprises

      Thorley, J., Garza-Reyes, J.A., Anosike, A.; University of Derby (WIT Press, 2019-01-30)
      In recent years, the literature surrounding the circular economy has grown. While the notion of reducing, recycling and reusing have become adopted practices in many organisations under the umbrella of sustainability, having a circular economy is arguably the next generation step, in terms of sustainability. A systematic literature review on the circular economy identified a gap in the research, regarding the impact at the micro level to be placed on small to medium enterprises. The research concludes that a paradigm shift in circular thinking at the micro level is required, and that further research is needed to identify new skills, resources, approaches, and business models to enable subject matter experts (SMEs) to adopt a circular practice.
    • Circular economy in the manufacturing sector: benefits, opportunities and barriers

      Kumar, V.; Sezersan, I.; Garza-Reyes, J.; Gonzalez, E.; AL-Shboul, M.; University of Derby (Emerald., 2019-04-18)
      In recent years, Circular Economy (CE) has come to prominence as an alternative to the classic approach of “make-use-dispose”. How companies can exploit the opportunities of CE to position themselves better are not well articulated in literature. This paper therefore aims to identify the barriers and opportunities of CE in the manufacturing sector through a socio-political, economic, legal and environmental perspective. The study adopts a positivist approach, which is deductive in nature. A survey questionnaire was designed and distributed to manufacturing companies operating in the UK and EU. The study used FAME database and social networking platform LinkedIn to identify manufacturing companies. More than 200+ companies were approached for this study and data collection lasted over two months. The study provides a comprehensive review of the CE literature and identifies a number of barriers and opportunities to CE implementation from socio-political, economic, legal and environmental perspective. The findings highlight key barriers, opportunities and benefits of CE for the manufacturing industries operating in the UK and EU. The findings are limited to 63 responses from the survey questionnaire distributed to manufacturing companies in the UK and EU. The present study aims to equip manufacturers with necessary understanding of the key opportunities and barriers to address the challenges encountered during the implementation of CE. This study adds to the limited empirical literature on CE barriers and opportunities to manufacturing organisations operating in the UK and EU. The paper also identifies barriers and opportunities of CE from socio-political, economic, legal and environmental lens.
    • A circularity measurement toolkit for manufacturing SMEs.

      Garza-Reyes, Jose Arturo; Valls, Ailin Salomé; Nadeem, Simon Peter; Anosike, Anthony; Kumar, Vikas; University of Derby; University of Warwick; University of the West of England (Taylor and Francis, 2018-12-24)
      The development and adoption of the concept of circular economy in the last two decades have been remarkable. However, despite its widespread adoption, little progress has been made regarding its measurement, especially in manufacturing SMEs. This paper, therefore, proposes a Circularity Measurement Toolkit (CMT) which enables the assessment of the degree of circularity in manufacturing SMEs. A conceptual CMT framework, which provided the basis for the proposed tool and that defined the different types of circular practices and a classification or levels of circularity was developed from an extensive literature reviewed. To ensure the structure’s accuracy of the proposed CMT in terms of requirements to be measured, the monitoring process and actions involved, the tool was verified through a Delphi-study. Furthermore, its practicality was validated through a case study approach in a manufacturing SME. This paper contributes by filling a gap in the CE measurement field through the proposal of the CMT. Besides providing an evaluation of the degree of circularity in the practices of manufacturing SMEs, companies can also employ the proposed CMT to identify corrective actions or future efforts for the adoption of CE practices.
    • Coalescing the lean and circular economy

      Nadeem, S.P.; University of Derby (IEOM Society, 2019-03)
      Growing population along with technological advancement to pace the production speed like never before has raised alarming concerns and attracted attention globally. Circular Economy, a fairly new concept has emerged to address such issues by proposing closed loop system in contrast to linear system. While the concept of Circular Economy presents a great potential, there yet remain the challenge for its adaptation in the existing manufacturing sector, especially at SMEs level. Many new techniques, methods and models are being developed, many of which require a complete change in the existing system, which not only have capital requirements but also upskilling labour. For SMEs it is challenging to have such transition due to higher capital and skills requirements. This research explores the possibility to combine the existing concept of Lean with Circular Economy for speedy and easy adaptation of Circular Economy principles within manufacturing sector, especially at SMEs level. A novel conceptually developed framework is proposed to merge the vitality of Lean and Circular Economy.

      Kumar, Anil; Kabra, Gaurav; Mussada, Eswara Krishna; Dash, Manoj Kumar; Rana, Prashant Singh; Xavier Institute of Management, Bhubaneswar, India; BML Munjal University; Indian Institute of Information Technology & Management, Gwalior (Madhya Pradesh), India; Thapar University Patiala, Punjab, India (Springer, 2017-05-30)
      A novel paradigm in the service sector i.e. services through the web is a progressive mechanism for rendering offerings over diverse environments. Internet provides huge opportunities for companies to provide personalized online services to their customers. But prompt novel web services introduction may unfavorably affect the quality and user gratification. Subsequently, prediction of the consumer intention is of supreme importance in selecting the web services for an application. The aim of study is to predict online consumer repurchase intention and to achieve this objective a hybrid approach which a combination of machine learning techniques and Artificial Bee Colony (ABC) algorithm has been used. The study is divided into three phases. Initially, shopping mall and consumer characteristic’s for repurchase intention has been identified through extensive literature review. Secondly, ABC has been used to determine the feature selection of consumers’ characteristics and shopping malls’ attributes (with > 0.1 threshold value) for the prediction model. Finally, validation using K-fold cross has been employed to measure the best classification model robustness. The classification models viz., Decision Trees (C5.0), AdaBoost, Random Forest (RF), Support Vector Machine (SVM) and Neural Network (NN), are utilized for prediction of consumer purchase intention. Performance evaluation of identified models on training-testing partitions (70-30%) of the data set, shows that AdaBoost method outperforms other classification models with sensitivity and accuracy of 0.95 and 97.58% respectively, on testing data set. This study is a revolutionary attempt that considers both, shopping mall and consumer characteristics in examine the consumer purchase intention.
