Uncertainty factors in supply chains

Purpose The purpose of this paper is to investigate the complex interrelationships among the key constructs, supply chain orientation (SCO), supply chain integration (SCI) and supply chain performance (SCP) in Indian manufacturing industries. These relationships have been studied using the relational view (RV) and the knowledge-based view (KBV) theoretical perspectives. Design/methodology/approach The conceptual model was derived from the existing body of knowledge in the supply chain domain. The study is based on a sample size of 122 data collected via face-to-face meetings with the Indian manufacturers using well-established scales. The covariance-based structural equation modeling was used to test the proposed hypotheses. Findings In Indian manufacturing and supply chains, SCO has a positive relationship with SCI and SCP. Moreover, the direct impact of SCO on SCP diminishes when SCI is used as a mediating variable. This study also observes positive impact of: i) SCO on SCP, ii) SCI on SCP and iii) discovery of mediating role of SCI on SCP under the theoretical lenses of RV and KBV. Research limitations/implications Cross-sectional survey of manufacturing firms of one country (using one response per firm) calls for validation covering other parts of the world and demands a longitudinal survey. This research will trigger more scholarly, practice and policy debate among researchers studying Indian and emerging economies context. Practical implications The notion of a holistic view of the SC with a focus on improving the customer value can enhance strategic partnerships among the SC partners (i.e. SCI) and overall SCP. Firms should make efforts to include SCI in SC designs to successfully transform SCO into SCP. Originality/value The originality of the research lies in studying the complex interrelationships among key concepts of SC in a unique Indian manufacturing context. The Indian supply chains operate in a set of unique characteristics, which have been detailed out in this paper. This paper not only establishes the mediating role of SCI for overall SCP in emerging economies but also enhances the scholarly knowledge in the SC domain. Most studies report SCO as a single-order construct, measured by scales comprising of only few items. The second-order SCO measures in this study bring credibility to the findings. Additionally, it contributes to both academicians and practitioners alike in the context of an integrated SC in emerging economies.

Purpose Existing supply chain (SC) performance models are not able to cope with the potential of intensive SC digitalisation and establish a relationship between decisions and decision criteria. The purpose of this paper is to develop an integrated knowledge-based system (KBS) that creates a link between decisions and decision criteria (attributes) and evaluates the overall SC performance. Design/methodology/approach The proposed KBS is grounded on the fuzzy analytic hierarchy process (fuzzy AHP), which establishes a relationship between short-term and long-term decisions and SC performance criteria (short-term and long-term) for accurate and integrated Overall SC performance evaluation. Findings The proposed KBS evaluates the overall SC performance, establishes a relationship between decisions (long-term and short-term) and decision criteria of SC functions and provides decision makers with a view of the impact of their short-term or long-term decisions on overall SC performance. The proposed system was implemented in a case company where the authors were able to develop a SC performance monitoring dashboard for the company’s top managers and operational managers. Practical implications The proposed KBS assists organisations and decision makers in evaluating their overall SC performance and helps in identifying underperforming SC functions and their associated criteria. It may also be considered as a tool for benchmarking SC performance against competitors. It can efficiently point to improvement directions and help decision makers improve overall SC performance. Originality/value The proposed KBS provides a holistic and integrated approach, establishes a relationship between decisions and decision criteria and evaluates overall SC performance, which is one of the main limitations in existing supply chain performance measurement systems.

Interest in smart factories and smart supply chains has been increasing, and researchers have emphasized the importance and the effects of advanced technologies such as 3D printers, the Internet of Things, and cloud services. This paper considers an innovation in dynamic supply-chain design and operations: connected smart factories that share interchangeable processes through a cloud-based system for personalized production. In the system, customers are able to upload a product design file, an optimal supply chain design and operations plan are then determined based on the available resources in the network of smart factories. The concept of smart supply chains is discussed and six types of flexibilities are identified, namely: design flexibility, product flexibility, process flexibility, supply chain flexibility, collaboration flexibility, and strategic flexibility. Focusing on supply chain flexibility, a general planning framework and various optimization models for dynamic supply chain design and operations plan are proposed. Further, numerical experiments are conducted to analyze fixed, production, and transportation costs for various scenarios. The results demonstrate the extent of the dynamic supply chain design and operations problem, and the large variation in transportation cost.

Impact of supply chain digitalization on supply chain resilience and performance: A multi-mediation model

This study aims at investigating the roles of supply chain integration and innovation on supply chain performance through a mediation mechanism of supply chain. This study develops a theoretical framework based on resource-based view and dynamic capability theory. Based on a quantitative study of 214 Saudi hospitals, an empirical analysis was made using a structural equation modelling with AMOS. Results revealed that supply chain integration and innovation positively affect supply chain resilience and performance. In addition, supply chain resilience has a positive and significant relationship with supply chain performance. Most significantly, the relationships of supply chain integration and of innovation to supply chain performance were found to be partially mediated by supply chain resilience. These results showed that integration and innovation have direct effects to improve supply chain performance and indirect ones when hospitals make efforts in developing their resilience. This study is important for top managers of Saudi hospitals to integrate their supply chains and innovate them to improve their resilience and performance.

Measuring the influence of digital twins on the sustainability of manufacturing supply chain: A mediating role of supply chain resilience and performance

The key objective of this research study is to delve into the factors affecting supply chain resilience to enhance supply chain performance through the mediation of supply chain resilience. A quantitative method of research was applied to perform this particular research. Data collection was performed using the questionnaire technique. As it was impossible to collect data from every member of the targeted population, a sample of data was calculated using G*power software and a sample size of 129 respondents. It was concluded that supply chain artificial intelligence, adaptive capability, and collaboration positively and significantly influence supply chain resilience and performance. At the same time, supply chain resilience also positively impacts supply chain performance. Thus, adopting resilience and other dynamic capacities can enhance organizational and supply chain performance. This research study provides insight to the manufacturing firms' practitioners and managers for improving their resilience level in the supply chain. This specific research study plays a significant role in literature by highlighting the concept of supply chain resilience and the supply chain performance of organizations.

PurposeDespite the economic growth in Ghana, the manufacturing industry faces numerous challenges in their supply chains. The study aims to investigate the mediated-moderated role of supply chain technological innovation (SCTI) in the relationship between supply chain resilience (SCR) and supply chain performance (SCP) of manufacturing firms. By exploring this relationship, the study seeks to provide insights that can help manufacturing firms overcome the challenges they face and improve their overall supply chain performance.Design/methodology/approachThe quantitative research approach and explanatory research design were utilised. A sample of 345 manufacturing firms was drawn from a population of 2495 manufacturing firms in the Accra metropolis. Analysis of this study was performed using the Partial Least Squares Structural Equation Modelling (PLS-SEM).FindingsIt was revealed that SCTI positively mediates the nexus between SCR and SCP. However, we document that SCTI negatively moderates the nexus. It is instructive to advocate that a mere presence of a more enhanced SCTI is not enough to improve upon SCP of manufacturing firms, but should be a channel through which SCR can improve SCP.Practical implicationsThis study highlights the need for managers of firms to prioritise investment in technological innovation as a means of enhancing SCR and ultimately improving supply chain performance. By understanding the SCTI mediated-moderated relationship between SCR and SCP, supply chain managers, logistics managers, operation managers, as well as procurement managers can develop more effective strategies to optimise their operations. This study provides valuable insights for managers and policymakers in developing and implementing supply chain resilience strategies that take into account the important role of SCTI.Originality/valueThe originality of the study lies in exploring the mediated-moderated effect of technological innovation on the nexus between resilience and performance of supply chains in developing economies, where firms often face unique challenges such as infrastructure limitations, political instability and economic uncertainty. By investigating the interplay of SCTI between SCR and SCP, researchers can develop new insights and strategies to help navigate these challenges and achieve success.

This study investigates how tech-driven integration (TDI), supply chain flexibility (SCF), and organizational ambidexterity (ORA) influence supply chain integration (SCI) and supply chain performance (SCP) in manufacturing firms. Supply chain uncertainty and agility are examined as moderating factors in the relationship between TDI, SCF, ORA, SCI, and supply chain performance. Based on insights from two experts and a comprehensive literature review, 35 measurement items were identified for the close-ended questionnaire design. Grounded in the resource-based view, the study employs the partial least squares structural equation modeling (PLS-SEM) approach to analyze 409 valid responses from the manufacturing industry. Our findings reveal that TDI and ORA positively impact SCI, while SCF has no significant influence on SCI. SCI directly influences SCP. Supply chain uncertainty moderates the two impacts: TDI and SCI; ORA and SCI. Besides, supply chain agility moderates the relationship between SCI and SCP. Our findings contribute to the literature by introducing a novel perspective on the relational dynamics of supply chain management by TDI and emphasizing the importance of organizational ambidexterity. We provide practical recommendations for managers to improve firm performance by strengthening the connections between TDI, SCF, ORA, uncertainty, agility, SCI, and SCP.

PurposeThis study aims to examine the impact of supply chain digitalization (SCD) on supply chain performance (SCP) with the integration of supply chain agility (SCA) and supply chain resilience (SCR) in manufacturing firms. Additionally, it investigates the moderating role of environmental dynamism (ED) in these relationships in the context of manufacturing firms.Design/methodology/approachA quantitative research design was employed, utilizing a structured questionnaire to collect data. The sample consisted of 374 valid responses from various managerial levels within manufacturing firms in Jordan. A purposive sampling technique was used to ensure that participants had relevant expertise in supply chain management. The data were analyzed using structural equation modeling (SEM) through Smart PLS software to test the proposed hypotheses.FindingsThe study found that SCD positively impacts SCP by enhancing both SCA and SCR. Digital technologies were shown to improve supply chain visibility, speed of decision-making and resource efficiency, which are essential for maintaining performance under uncertain conditions. Furthermore, ED significantly moderates the relationship between digitalization and SCP, indicating that the benefits of digitalization on SCA and SCR are more pronounced in highly dynamic environments.Originality/valueThis study contributes to the literature by offering an investigation on the role of SCD in influencing SCA, SCR and ultimately SCP in manufacturing firms. It also sheds light on the moderating effect of ED, providing a deeper understanding of the conditions under which digital transformation in supply chains is most beneficial. The study was based on three theoretical foundations: the resource-based view (RBV), the dynamic capabilities theory (DCT) and the contingency theory (CT).

Arabica Coffee is one of Bali's primary products in trade activities, both foreign and domestic. The rise of the downstream coffee industry has resulted in an increasing demand for Arabica coffee. Balinese Arabica coffee processing businesses are required to be able to compete by strengthening their supply chains. Changes in the very dynamic business situation require coffee processing businesses to be able to adapt and take adjustment steps. For this reason, evaluations related to supply chain performance must be carried out consistently. This study aims to evaluate the performance of the Kintamani Bali Arabica coffee supply chain. The research approach utilised a quantitative survey method. The research informants used were 55 people, consisting of farmers, agricultural extension workers, coffee processing businesses, coffee shops, and academics. The data was analysed using the SCOR (Supply Chain Operation References) approach and the Analytical Hierarchy Process (AHP) method. The results of this study obtained as many as 49 validated key performance indicators. The results of the measurement of the performance of the Kintamani Bali Arabica Coffee processing business supply chain showed a result of 84.97%, with a good category. It is hoped that the coffee processing business will be able to improve the performance of the supply chain in the plan process, through improving the information system by continuously recording, and deploying workforces that have expertise in business information documentation activities.

In local and globalized markets, warehouses are crucial supply chain nodes. This study aimed to investigate the effect of warehousing on supply chain performance: A case of Inyange Industries Ltd. The goals were to evaluate how inventory management, warehouse capacity building, and material handling affects supply chain performance in Inyange Industries Ltd. This research experimented with three different theories: Just-in-time, Lean, and Triple-A supply chain. The population of this study were 105 staff members of Inyange Industries Ltd. Therefore, census was conducted because the population size is affordable and the researcher can be able to contact all the respondents. Quantitative data were analyzed using inferential research methodology in this study. Questionnaires were used to gather primary data, which was then analyzed. Data analysis was carried out using the Statistical Package for the Social Sciences (SPSS), and descriptive and inferential statistics were used to show the study's results. According to the research, supply chain performance is positively and significantly affected by both automated and manual material handling. Mechanical material handling, on the other hand, improves supply chain performance, but not much. Inyange Industries' supply chain performance is influenced by the material handling systems to the tune of 19.3%, as shown by the modified R2 value of 0.193. According to the research, supply chain performance is positively and significantly affected by inventory counts, warehouse management systems, and inventory organization. A 0.967 adjusted R^2 value suggests that 96.7% of the variation in Inyange Industries' supply chain performance is explained by the inventory management techniques. According to the research, supply chain effectiveness is positively and significantly impacted by warehouse demand planning, design, and management. Warehouse capacity planning techniques at Inyange Industries account for 95.4% of the variation in supply chain performance, as shown by the modified R2 value of 0.954. The research concluded that material handling, inventory management, and warehouse capacity planning are all important warehouse management measures that significantly impact supply chain performance for the better. The methods used by Inyange Industries Ltd. for managing their warehouses have resulted in an improvement in supply chain performance of 87.2%. The regression coefficients, supported by their t-test values and Beta coefficients, highlight both the significance and strength of relationships between independent and dependent variables. Material Handling demonstrated the greatest impact (β1=0.532, t=8.556, p=0.000), followed by Inventory Management (β2=0.379, t=6.147, p=0.000), and Warehouse Capacity Planning (β3=0.172, t=3.268, p=0.002), emphasizing their respective contributions to Supply Chain Performance of Inyange Industries Ltd.'s supply chain. This proved that material handling in warehouse management has a major influence on supply chain performance. Because the p-value was lower than 5%, we may say that the association is statistically significant. The research concluded that both automated and human material handling should get additional funding. To maximize efficiency in stock-taking as well. Previous studies have looked at a variety of organizational factors that affect performance of supply chains. To further understand how warehouse management strategies affect overall performance, more research is needed.

Nowadays, concerns about environmental issues are increasing. Therefore, companies and producers are under pressure from government rules and regulations on one hand, and on the other hand, maintaining customer satisfaction concerning cares about the environment. Green supply chain management (GSCM) is a procedure to increase efficiency and decrease environmental effects for companies that collaborate with customers and suppliers. According to GSCM, there is some research about applying green aspects of purchasing, design, manufacture, distribution, packaging, marketing, and reverse logistics of supply chains to improve their company’s performance regarding environmental issues. Moreover, recently, DEA as a nonparametric model is used to evaluate the efficiency and performance of supply chains as decision-making units (DMUs). However, previous studies on efficiency improvement in GSCM did not investigate the effect of some economic and environmental factors together such as service level, emissions (CO2), and size of the supply chains (arcs) on the efficiency of the whole supply system. These factors are essential as they can affect the manager’s ability to distinguish the true performance of a green supply chain. Thus, evaluating the efficiency of GSCM by DEA models and imposing the green principles to find out the efficient ones for increasing management performance is vital. Fulfilling the mentioned research gap, this paper developed a benchmark approach to verifying efficient DMUs and potential efficient DMUs which may improve costs and efforts to become efficient. In the case study, the benchmarks and potentially efficient DMUs are found by DEA standard models and slight adjustment is conducted for potentially efficient DMUs to change their status to efficient DMUs. Moreover, the effect of some green principles on the efficiency value of DMUs is verified using Tobit regression before and after the mentioned modification. A set of realistic results provided for the priority of potential DMUs modification confirmed the applicability of the proposed procedure.

Optimal supply chain design depends on the business context the chain caters for. In this dissertation, we are concerned with attaining and maintaining this alignment between a firm's supply chain portfolio and its business context. Following an introduction in Chapter 1, in Chapter 2 of this dissertation, we analyze the influence of a firm's product types on optimal supply chain design: Academics and practitioners agree that functional products are best delivered via physically efficient supply chains, while innovative products are best delivered via market responsive chains. However, to date, only a few firms have systematically adjusted their supply chain strategies according to this argument. Instead of carrying only one product type, firms deliver a number of both functional and innovative products in parallel complicating the alignment of supply chain portfolios with product portfolios. We address this issue and analyze in detail a firm's optimal supply chain portfolio as a function of its product portfolio. We target the tactical level of decision-making and develop a generic mathematical model to analyze how product portfolios affect the optimal setup of supply chain portfolios. We identify generic problem properties and perform extensive sensitivity analysis to illustrate our findings with numerical examples. Our results indicate that effective supply chain and product portfolio alignment holds the potential for significant cost savings. Because of the large number of factors influencing the optimal set-up, however, profound quantitative analysis is required to exploit the full potential of aligning the supply chain with the product portfolio and to guide implementation. In Chapter 3, we extend our modeling framework and take into account the fact that a firm's products and global business parameters, such as labor rates and transportation costs, evolve over time. Hence, firms need to adapt their supply chain portfolios frequently to stay aligned in the long term. Adapting a well-established supply chain portfolio, however, may involve high costs and expose a firm to unforeseeable risks. We address this issue, differentiating business dynamics into product portfolio dynamics and global business dynamics, and classifying supply chain adaptation into high, medium and low. Building on these classifications, we extend our mathematical model to analyze how much supply chain adaptation a firm actually requires to respond to the business dynamics it faces. Our results indicate that supply chain adaptation may indeed be crucial for a firm to retain its competitiveness. The need for adaptation, however, varies widely across firms: For example, a firm faced with product portfolio commoditization may be required to adapt its entire manufacturing footprint, while a firm with a high product turnover rate may not need to adapt its supply chain portfolio at all. Furthermore, the need for supply chain adaptation is not only determined by the business context in which a firm operates, but can also be manipulated by the firm's product portfolio decisions. Finally, a firm should carefully align its supply chain portfolio with the employed supply chain adaptation strategy to exhaust attainable benefits. In Chapter 4, we widen our scope and develop a step-by-step process to guide sustained alignment between a firm's business context and its supply chain portfolio in practice. Drawing on academic literature, insights from our quantitative models, and extensive interviews with executives from leading firms, we propose and detail four process steps. In the first step we suggest challenging the performance of a firm's current supply chain setup and identifying pressure points to evaluate how acute supply chain realignment is. As a second step we propose and detail a business context analysis to identify what a supply chain lacks and potential areas for realignment. To complement the previous analysis, in a third step, we frame and discuss generic options for long-term supply chain strategy. As a fourth step, we lay out opportunities and pitfalls during the project implementation. We conclude with recommendations on how to stay aligned in the long term. We end the dissertation with a conclusion in Chapter 5.
