Yayın Assembly line balancing by using axiomatic design principles: An application from cooler manufacturing industry(Universidad Politecnica de Valencia, 2020) Zaim, Selim; Demirel, Ömer Fahrettin; Zaim, Selim; Demirel, Ömer Fahrettin; Yılmaz, Ömer Faruk; Demirel, Ömer Fahrettin; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme BölümüThe philosophy of production without waste is the fundamental belief behind lean manufacturing that should be adopted by enterprises. One of the waste elimination methods is assembly line balancing for lean manufacturing, i.e. Yamazumi. The assembly line balancing is to assign tasks to the workstations by minimizing the number of workstations to the required values. There should be no workstation with the excessively high or low workload, and all workstations must ideally work with balanced workloads. Accordingly, in this study, the axiomatic design method is applied for assembly line balancing in order to achieve maximum output with the installed capacity. In order to achieve this aim, all improvement opportunities are defined and utilized as an output of the study. Computational results indicate that the proposed method is effective to reduce operators’ idle time by 12%, imbalance workload between workstations by 38%, and the total number of workers by 12%. As a result of these improvements, the production volume is increased by 23%.Yayın Examining the role of employee social intrapreneurial behavioural and job satisfaction as mediators of employee commitment(Richtmann Publishing, 2024) Malaj, Ardita; Alsaber, Ahmad R.; Alboloushi, Bedour; Alkandari, Anwaar; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study investigates the series of mediating effects of employee social intrapreneurial behaviour and job satisfaction on innovative organizational culture and employee commitment. This research aims to explore the relationship between an innovative organizational culture, employee intrapreneurial behaviour, employee job satisfaction, and employee job commitment in the manufacturing sector of Kuwait, a developed economy. Literature reviews analyses core concepts and their associated domains to discover gaps in existing research by examining definitions, dimensions, and relevance. The examination of relevant research identified significant knowledge deficiencies. The framework examines employee social intrapreneurial behaviour by incorporating several aspects such as idea generation, idea promotion, and idea realization. The current study utilized quantitative research methods. The researcher utilized SPSS version 28 to analyses the numerical data collected through a questionnaire to meet the study questions. The questionnaire was distributed using both computerized and self-administered ways to increase the response rate. We have obtained an extensive list of contact names for all manufacturing companies in Kuwait. The study is based on three primary theories: Self Determination Theory, Social Exchange Theory, and Theory of Planned Behaviour. This study aims to develop a new formula to promote a culture of social innovation. The research findings suggest that Employee Social Intrapreneurial Behaviour (ESIB) has a notable influence on manufacturing enterprises in Kuwait. Employee social intrapreneurial behaviour and job satisfaction were shown to have a mediating impact on innovative organizational culture and employee commitment. The research's theoretical framework enhances managers' understanding of the significance of intrapreneurship and how organizations can facilitate its development at both individual and organizational levels.Yayın Link between digital technologies adoption and sustainability performance: Supply chain traceability/resilience or circular economy practices(Multidisciplinary Digital Publishing Institute (MDPI), 2024) Duman Altan, Aylin; Beyca, Ömer Faruk; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüTechnological progress and digitalization have ushered in significant transformations in business strategies. At present, research is scarcely focused on the influence of the adoption of digital technologies (DTs) on establishing comprehensive relationships within the context of a circular economy (CE), and the supply chain (SC) framework to contribute to the Resource-Based View (RBV) theory. This study utilizes survey data collected from 235 manufacturing practitioners employed by Turkish manufacturing enterprises to explore a model elucidating the relationship between DTs adoption and sustainability performance (SP) through supply chain traceability (SCT), supply chain resilience (SCR), and circular economy practices (CEPs), based on 10R strategies. Through this linkage, this research accentuates that the exclusive integration of CEPs with digital technology solutions is insufficient for industrial enterprises to attain their long-term sustainability goals. It underscores the necessity of ensuring SCT and/or SCR in this context.Yayın Unveiling the drivers of global logistics efficiency: Insights from cross-country analysis(MDPI, 2024) Bayraktar, Erkan; Eryarsoy, Enes; Kosanoglu, Fuat; Acar, Mehmet Fatih; Zaim, Selim; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study presents a novel approach to assess countries’ relative logistics performance differentials and identifies the underlying drivers using a data envelopment analysis (DEA) approach. The findings offer strategic insights and provide nations with valuable guidance in navigating the dynamic landscape of global logistics competitiveness. Recognizing the pivotal role of logistics in fostering economic activity and contributing to sustainability, we utilize the Logistics Performance Index (LPI) within the DEA model to gauge efficiencies at the country level and scrutinize influencing factors. Our findings indicate that international shipment practices in the last decade, as well as tracking and tracing recently, no longer contribute to the competitiveness of the countries, despite their potential for improvement. The overall change in logistics efficiency during the last decade remained relatively marginal, primarily driven by the frontier-shift effect. However, notable disparities among the country performance groups, particularly in adopting technological advancements, are manifested in the frontier-shift effect. Countries with lower logistics performance should prioritize addressing structural challenges related to customs, infrastructure, quality of logistics services, and timeliness. Medium-performance countries, while benefiting from a focus on customs, tracking and tracing, and timeliness in the early 2010s, are advised to align their efforts with high-performance countries by emphasizing managerial aspects in recent times.Yayın Using machine learning tools for forecasting natural gas consumption in the province of Istanbul(Elsevier, 2019) Beyca, Ömer Faruk; Ervural, Beyzanur Çayır; Tatoğlu, Ekrem; Özuyar, Pınar Gökçin; Zaim, Selim; Tatoğlu, Ekrem; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüCommensurate with unprecedented increases in energy demand, awell-constructed forecastingmodel is vital to managing energy policies effectively by providing energy diversity and energy requirements that adapt to the dynamic structure of the country. In this study, we employ three alternative popular machine learning tools for rigorous projection of natural gas consumption in the province of Istanbul, Turkey's largest natural gas-consuming mega-city. These tools include multiple linear regression (MLR), an artificial neural network approach (ANN) and support vector regression (SVR). The results indicate that the SVR is much superior to ANN technique, providing more reliable and accurate results in terms of lower prediction errors for time series forecasting of natural gas consumption. This study could well serve a useful benchmarking study for many emerging countries due to the data structure, consumption frequency, and consumption behavior of consumers in various time-periods.Yayın Corporate governance and firm performance in emerging markets: Evidence from Turkey(Elsevier, 2019) Tatoğlu, Ekrem; Zaim, Selim; Tatoğlu, Ekrem; Zaim, Selim; Çiftçi, İlhan; Tatoğlu, Ekrem; Wood, Geoffrey; Demirbağ, Mehmet; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme BölümüThis is a study of the relationship between context, internal corporate governance and firm performance, looking at the case of Turkey, an exemplar of family capitalism. We found more concentrated ownership, often in the hands of families, led to firms performing better; concentrated ownership means that controlling families bear more of the risks of poor performance. Less predictably, given that the institutional environment is so well attuned to family ownership, we found that mechanisms that accord room for a greater range of voices and interests within and beyond families – larger boards and foreign ownership stakes – seem to also make for positive performance effects. We also noted that increase in cross ownership did not influence market performance, but was negatively associated with accounting performance. Conversely, we found that a higher proportion of family members on boards had no discernable effect on performance. Our findings provide further insights on the relationship between the type of institutions encountered in many emerging markets, internal corporate governance configurations and firm performance.Yayın Business analytics and firm performance: The mediating role of business process performance(Elsevier, 2019) Aydıner, Arafat Salih; Tatoğlu, Ekrem; Bayraktar, Erkan; Zaim, Selim; Delen, Dursun; Tatoğlu, Ekrem; Zaim, Selim; Delen, Dursun; Yönetim Bilimleri Fakültesi, İşletme BölümüDue to the rapidly increasing popularity of business analytics (BA), investigation of the antecedents/determinants of the adoption of BA and the subsequent impact of the same to the firm performance has become an important research topic. Drawing on the fundamentals of the resource-based view (RBV), this study proposes a model that examines the effects of the BA adoption on business process performance (BPER) and the mediating role that BPER plays in the relationship between the adoption of BA and firm performance (FP). Based on the data collected from 204 medium- to high-level business executives in various industries, the results of this empirical study indicate that the adoption of BA positively influences BPER. There is also positive relationship between BPER and FP. Finally, the results show that BPER fully mediates the relationship between BA adoption and FP.Yayın The effect of organizational culture, supplier trust and information sharing on supply chain viability(Springer, 2024) Acar, Mehmet Fatih; Torgalöz, Alev Özer; Eryarsoy, Enes; Zaim, Selim; Ruel, Salomée; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study investigates the impact of intangible resources such as adhocracy culture (ADC), information sharing with suppliers (IS), and supplier trust (ST) on supply chain viability (SCV) under high inflation environment. To do this, a conceptual model is developed to analyze the associations between these suggested variables. Using on a cross-sectional survey, data are collected from 216 supply chain (SC) and production practitioners based in Türkiye who are medium- to senior-level managers. To analyze our theoretical model, we processed our data and model using lavaan package in R. The results show a significant relationship between ADC and SCV. Additionally, both of IS and ST capabilities are found to have a strong mediating effect on the ADC and SCV relationship. The results of this study will provide insight for managers and researchers to prevent the negative effects of SC disruptions due to the high inflation or other type of stress tests. Extant research has investigated the SCV with different crises like COVID-19 pandemic however, the study is the first research that examines SCV under high inflation stress test. Moreover, ADC, IS and ST have not widely appeared in SCV literature. In this regard, this research also contributes to the ongoing efforts of investigating the antecedents of SCV.Yayın An analytic approach to assessing organizational citizenship behavior(Elsevier, 2017) Tatoğlu, Ekrem; Zaim, Selim; Delen, Dursun; Tatoğlu, Ekrem; Zaim, Selim; Delen, Dursun; Arda, Özlem Ayaz; Delen, Dursun; Tatoğlu, Ekrem; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study examines the organizational citizenship behavior (OCB) of employees by designing and developing an analytic network process (ANP) methodology. The viability of the proposed methodology is demonstrated via the sales representatives of Beko, a brand name controlled by Koç Group. We first develop a conceptual framework based on qualitative research methods – in-depth interviews and focus group sessions. We employ the principles of ANP methodology to examine and discover the inter-relationships among the OCBs. This process results in a descriptive model that encapsulates the findings from both qualitative and analytics methods. Necessity, altruism, departmental, compliance, and independence are the underlying dimensions of OCBs found to be the most influential/important. The key novelty of this study resides in designing and developing a prescriptive analytics (i.e. ANP) methodology to evaluate the OCBs, which is rare in the area of organizational behavior (a managerial field of study that have been dominated by traditional statistical methods), and thus serves as a useful contribution/augmentation to the business/managerial research methods, and also extends the reach/coverage of analytics-based decision support systems research and practice into a new direction.Yayın Toward a holistic understanding of sustainability in corporations: Resource-based view of sustainable supply chain management(Emerald Publishing, 2021) Tatoğlu, Ekrem; Zaim, Selim; Tatoğlu, Ekrem; Zaim, Selim; Ayaz Arda, Özlem; Montabon, Frank; Tatoğlu, Ekrem; Gölgeci, İsmail; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme BölümüPurpose While the three interconnected aspects of the triple bottom line -environmental, social and economic sustainability- are well-established, these aspects have insufficiently been addressed together in the supply chain management literature. Thus, the purpose of this paper is to examine whether environmental and social performance mediates the relationship between environmental management practices and operational performance and whether operational performance mediates the relationship between environmental and social performance and financial performance. Design/methodology/approach Drawing on a data set of 208 firms operating in a wide range of manufacturing industries, the authors test the hypotheses using structural equation modeling. The research context for the study is Turkey, an important emerging market and one of the nexuses of European and Asian supply chains. Findings The findings indicate that all three aspects of sustainability have mutually supportive relationships as demonstrated by positive mediating mechanisms between environmental management practices and operational performance and between environmental and social performance and financial performance. The mediation results correspond with the resource-based view. They indicate that building up capabilities and resources in the form of environmental management practices supports three areas of the triple bottom line and boosts firms' financial performance. Originality/value Research on sustainability is well-established, yet supply chain management research has, thus, far paid insufficient attention to all three aspects. This paper, thus, sets itself apart by explicitly considering all three aspects of sustainability and contributes to understanding how they relate to one another.
