Sustainable supply chain management and partner engagement to manage climate change information

Climate change poses significant new risks and challenges for businesses and their supply chains. Additionally, in many sectors, Scope 3 indirect greenhouse gas emissions resulting from the sourcing and distribution of goods and services are larger than firms' own carbon footprints. Here we study how firms engage their key stakeholders in their supply chains in obtaining, processing, and transferring relevant climate change‐related information designed to overcome information asymmetry and drive sustainable development. Grounded in organisational information‐processing theory (OIPT), we draw on data from the Carbon Disclosure Project's Climate Change Supply Chain initiative for a qualitative content analysis of a large sample of global firms. Consistent with OIPT, we find that although firms primarily engage their supply chain partners in a variety of ways to reduce information uncertainty around indirect emissions data, effectively interpreting and managing broader sustainability information equivocality becomes a growing priority. Our findings further suggest that firms engage suppliers, customers, and other supply chain partners through basic, transactional, and collaborative types of engagement. We contribute to literatures on interorganisational information processing and sustainable supply chain management by providing a more detailed understanding of how firms engage supply chain partners in the context of climate change.     

Understanding the dynamics of global supply chain sustainability initiatives: The role of institutional distance from the buyer's perspective

Research points to sustainable supply chain management as a core strategic goal for most global firms. However, managers continue to struggle with implementing successful sustainability initiatives both internally and throughout their globally dispersed supply chains. Using grounded theory, our findings uncover a potential explanation for how firms manage sustainability initiatives in the context of global supply chain management, from a buyer's perspective. Institutional theory of the firm is applied to help explain the challenges of developing and implementing global supply chain sustainability-related initiatives within buyer-supplier relationships. Analysis of the data from qualitative interviews show that institutional distance is an influential factor that produces mixed effects on the global buyer-supplier relationships in our sample in the context of buyer and supplier strategic orientation toward sustainability. The findings can help guide managers when approaching sustainability-related initiatives in the context of global supply chains. Theoretical and managerial implications are discussed as well as areas for future research.     

An analysis of job dissatisfaction and turnover to reduce global supply chain risk: Evidence from China

Suppliers’ labor problems in developing countries have emerged as a key risk in global supply chains. In China's coastal industrial zones, where most Fortune 500 companies have established their manufacturing bases, local suppliers are facing serious labor turnover problems. High labor turnover rates have caused poor quality, low productivity, and unfilled orders in supply chains. Applying a combination of quantitative techniques to determine the reasons why workers leave China's export factories, this research tries to identify the root causes of job dissatisfaction leading to turnover and provides managerial implications that may assist managers in dealing with labor-related supply chain risks.     

Supply chain planning of vaccine and pharmaceutical clusters under uncertainty: The case of COVID-19

As an abrupt epidemic occurs, healthcare systems are shocked by the surge in the number of susceptible patients' demands, and decision-makers mostly rely on their frame of reference for urgent decision-making. Many reports have declared the COVID-19 impediments to trading and global economic growth. This study aims to provide a mathematical model to support pharmaceutical supply chain planning during the COVID-19 epidemic. Additionally, it aims to offer new insights into hospital supply chain problems by unifying cold and non-cold chains and considering a wide range of pharmaceuticals and vaccines. This approach is unprecedented and includes an analysis of various pharmaceutical features such as temperature, shelf life, priority, and clustering. To propose a model for planning the pharmaceutical supply chains, a mixed-integer linear programming (MILP) model is used for a four-echelon supply chain design. This model aims to minimize the costs involved in the pharmaceutical supply chain by maintaining an acceptable service level. Also, this paper considers uncertainty as an intrinsic part of the problem and addresses it through the wait-and-see method. Furthermore, an unexplored unsupervised learning method in the realm of supply chain planning has been used to cluster the pharmaceuticals and the vaccines and its merits and drawbacks are proposed. A case of Tehran hospitals with real data has been used to show the model's capabilities, as well. Based on the obtained results, the proposed approach is able to reach the optimum service level in the COVID conditions while maintaining a reduced cost. The experiment illustrates that the hospitals' adjacency and emergency orders alleviated the service level significantly. The proposed MILP model has proven to be efficient in providing a practical intuition for decision-makers. The clustering technique reduced the size of the problem and the time required to solve the model considerably.     

The role of control power allocation in service supply chains: Model analysis and empirical examination

In complex and competitive business environment, there have been many examples of supply chain members fighting for power. Therefore, researchers have begun focusing on the impact of control power allocation on the supply chain. This paper examines the allocation of power in different service supply chain relationships, analyzing the impact of service level on optimal control power allocation and comparing the differences between the optimal power distribution in service supply chains and that of manufacturing supply chains. We adopt a mathematical model building method to discuss this issue, verifying the theoretical perspectives through empirical studies of China's largest state-owned logistics company, the China Railway Company, and the private ownership enterprise, Tianjin SND Logistics Company. We also develop a conceptual model of the influence of control power on the performance of service supply chains, based on the modeling and case analysis. The conceptual model shows several results: the control power allocation determines the dominant structure of the supply chain; the service provider's wholesale pricing strategy and the service integrator's sales price strategy present different outcomes under various dominant structures of the supply chain, which will greatly affect the performance of the corresponding supply chain; and the relationship between the supply chain dominant structure and the price can be adjusted by the service level.     

Achieving supply chain ‘Leagility’ through a project management orientation

Many forces have combined to make today's supply chains more complex than ever before. These forces include the significant trend to out-sourcing; the growth of offshore manufacturing and procurement; the rising demand for customer-specific solutions and the globalisation of markets. The paper highlights the challenges that organisations must address in order to gain and retain competitiveness in today's markets – in particular, the need to achieve ever lower costs while simultaneously enhancing responsiveness. In other words, the need is to develop hybrid supply chains that are both ‘lean’ and ‘agile’. Using a single case study of a global telecommunications company as an example, the authors demonstrate how supply chain complexity can effectively be mastered by adopting a project management orientation and in the process enabling outcomes that are ‘leagile’, that is, both lean and agile.     

Improving agility and resilience of automotive spares supply chain: The additive manufacturing enabled truck model

The global supply chain disruption by the COVID-19 pandemic is difficult, if not impossible, to estimate as over 94% of the top 1000 fortune companies were badly affected. The need for building resilient supply chains to mitigate the effect of such disruptions is rising rapidly than ever before across the global business spectrum. Building resilience in the automotive spare parts (ASPs) supply chain is critically important as any disruption to automotive spares supply chain will affect the operations of the logistics sector, the backbone of global supply chains. This research work contributes to improving the resilience of the automotive spare parts supply chain by proposing a Viable Supply Chain (VSC) framework design that incorporates Additive Manufacturing (AM) enabled trucks in the automotive spares supply chain network. Based on the proposed model, conceptual case models are developed and tested with proposed AM enabled truck manufacturing closer to end customer. A heuristic approach called shortest time heuristic is also proposed to solve the routing and scheduling of an AM enabled truck to deliver customers’ orders of the spare parts through an online platform. Importantly, the study demonstrate how additive manufacturing can help the ASPs industry to switch from the existing practice of make-to-stock to a more efficient inventory management and cost saving make-to-order model while also achieving resilience and sustainability in by providing a source of spares support for discontinued models of vehicles.     

An empirical investigation into supply chain vulnerability

A growing number of academicians and practitioners have put supply chain risks on their agendas, particularly triggered by a recent series of catastrophic events that have disrupted economies and supply chains around the globe. Given the increasing awareness of this important topic, the purpose of this research was to study supply chain risks in more detail and to investigate the relationship between supply chain vulnerability and supply chain risk. Responses from 760 executives from firms operating in Germany reveal that supply chain characteristics such as a firm's dependence on certain customers and suppliers, the degree of single sourcing, or reliance on global supply sources are relevant for a firm's exposure to supply chain risk. Overall, this research represents the first large-scale investigation of this important relationship and provides a finer understanding of the antecedents of supply chain vulnerability.     

Impact of epidemic outbreaks (COVID-19) on global supply chains: A case of trade between Turkey and China

COVID-19 has negative impacts on supply chain operations between countries. The novelty of the study is to evaluate the sectoral effects of COVID-19 on global supply chains in the example of Turkey and China, considering detailed parameters, thanks to the developed System Dynamics (SD) model. During COVID-19 spread, most of the countries decided long period of lockdowns which impacted the production and supply chains. This had also caused decrease in capacity utilizations and industrial productions in many countries which resulted with imbalance of maritime trade between countries that increased the freight costs. In this study, cause and effect relations of trade parameters, supply chain parameters, demographic data and logistics data on disruptions of global supply chains have been depicted for specifically Turkey and China since China is the biggest importer of Turkey. Due to this disruption, mainly exports from Turkey to China has been impacted in food, chemical and mining sectors. This study is helpful to plan in which sectors; the actions should be taken by the government bodies or managers. Based on findings of this study, new policies such as onshore activities should consider to overcome the logistics and supply chain disruptions in global supply chains. This study has been presented beneficial implications for the government, policymakers and academia.     

Traders as sustainability governance actors in global food supply chains: A research agenda

Corporate actors are rapidly gaining ground as nontraditional forms of authority that shape sustainability governance efforts in global food supply chains. This paper highlights the critical, but underresearched role of traders—companies whose core business lies in the movement and exchange of agricultural commodities between producers and manufacturers—in linking corporate sustainability ambitions to on-the-ground impacts. Drawing on a systematic analysis of the major transnational corporations trading cocoa, coffee, and palm oil, we present advantages and potential pitfalls of relying on traders as implementers of sustainability governance and outline a future research agenda that focuses on producer-level impacts, changes in supply chain organization and power dynamics, and traders' interactions with state and other nonstate actors. At the intersection of supply chain management, political economy, geography, and global governance, research on traders as key sustainability governance actors also provides novel opportunities for interdisciplinary work and stakeholder engagement.

Demand chain management theory: constraints and development from global aerospace supply webs

This paper develops an empirical and theoretical approach to where strategic capabilities should lie within global aerospace supply chains. Theory from transaction cost economics (TCE) and the resource-based view (RBV) of the firm are applied to the aerospace sector and used to underpin a theory of demand chain management (DCM). A two-stage research process was used to generate and validate data from aerospace supply chain case studies. Demand chain driver and resource-based response categories were identified from these data and are presented. Concluding comments concern current limits of a demand chain theory and implications for practitioners.     

Concentrated supply chain membership and financial performance: Chain- and firm-level perspectives

This study reports evidence that concentrated 3-firm supply chains achieve superior financial performance, and that supply chains’ financial performance varies systematically with measures of chain concentration and chain duration. Results from firm-level analyses suggest that the profitability benefits of supply chain relationships are captured predominantly by downstream chain members, whereas cash cycle benefits are realized throughout the supply chain. Firm-level tests also reveal that chain members’ financial performance varies systematically with measures of downstream bargaining power, downstream relationship duration, and degree of supply consolidation. The study's chain- and firm-level analyses employ data extracted from sample firms’ publicly available financial reports, including their major customer disclosures under Statement of Financial Accounting Standards Nos. 131 (1997) and 14 (1976).     

The raw material basis of global value chains: allocating environmental responsibility based on value generation

A new approach to allocate environmental responsibility, the ‘value added-based responsibility’ allocation, is presented in this article. This metric allocates total environmental pressures occurring along an international supply chain to the participating sectors and countries according to the share of value added they generate within that specific supply chain. We show that – due to their position in global value chains – certain sectors (e.g. services) and countries (e.g. Germany) receive significantly greater responsibility compared to other allocation approaches. This adds a new perspective to the discussions concerning a fair distribution of mitigation costs among nations, companies and consumers.     

Postponement strategy for international transfer of products in a global supply chain: A system dynamics examination

This paper contributes to research on “postponement” strategy in the context of a global production–distribution system of an automobile manufacturer. It proposes a model that integrates multiple considerations germane to global supply chains. Postponement is important in this context because it is necessary to consider international transfers and tariffs, and it is important to appropriately account for the impact of postponement on total costs. Consideration of several key variables such as shipping point, customs tariff, and cost differences between countries is essential to derive full benefits from postponement strategy in global supply chains. International transfer of goods among countries in global automobile industry is complex and dynamic because of the multitude of factors that must be considered. The paper develops insights regarding postponement strategy in global supply chains via a system dynamics simulation model. The model draws on the experiences of a Korean automobile manufacturer with operations in developing and developed countries.     

Modeling loss-propagation in the global supply network: The dynamic agent-based model acclimate

World markets are highly interlinked and local economies extensively rely on global supply and value chains. Consequently, local production disruptions, for instance caused by extreme weather events, are likely to induce indirect losses along supply chains with potentially global repercussions. These complex loss dynamics represent a challenge for comprehensive disaster risk assessments. Here, we introduce the numerical agent-based model acclimate designed to analyze the cascading of economic losses in the global supply network. Using national sectors as agents, we apply the model to study the global propagation of losses induced by stylized disasters. We find that indirect losses can become comparable in size to direct ones, but can be efficiently mitigated by warehousing and idle capacities. Consequently, a comprehensive risk assessment cannot focus solely on first-tier suppliers, but has to take the whole supply chain into account. To render the supply network climate-proof, national adaptation policies have to be complemented by international adaptation efforts. In that regard, our model can be employed to assess reasonable leverage points and to identify dynamic bottlenecks inaccessible to static analyses.

Quality in competitive fresh produce supply chains with application to farmers' markets

Fresh produce supply chains have special characteristics, notably, that the quality of the product (fruit or vegetable) deteriorates continuously over time, even under ideal conditions. In this paper, we begin with explicit formulae for fresh produce quality deterioration based on chemistry and temperature and provide a path-based framework. We then focus on farmers' markets, the popularity of which has been growing due to consumers' greater awareness of and interest in product quality and emphasis on health. Farmers' markets, as examples of direct to consumer channels and shorter supply chains, are studied in the framework of game theory in both uncapacitated and capacitated versions. A case study of apples in Massachusetts, under various scenarios, including production disruptions, provides quantitative evidence of the applicability of our supply chain network approach.
