Author(s):  
Dimitrios Vlachos

As the practices of offshoring and outsourcing force the supply chain networks to keep on expanding geographically in the globalised environment, the logistics processes are becoming more exposed to risk and disruptions. Thus, modern supply chains seem to be more vulnerable than ever. It is clear that efficient logistics risk and security management emerges as an issue of pivotal importance in such competitive, demanding and stochastic environment and is thus vital for the viability and profitability of a company. In this context, this chapter focuses on a set of stochastic quantitative models that study the impact of one or more supply chain disruptions on optimal determination of single period inventory control policies. The purpose of this research is to provide a critical review of state-of-the-art methodologies to be used as a starting point for further research efforts.

Be it agriculture, manufacturing or production of energy, all are a part of supply and demand mechanics controlling freights and container ships, bringing the world’s industry together leading to globalization of economy. The world’s food, products were transported by the shipping industry with supply chain as its core. 94% of the Fortune 500 companies are seeing covid 19 supply chain disruptions as per 2020 Forbes report. Supply chains of today are very intricate and interconnected; disruption at one part can spread in an unpredicted manner. This paper helps the reader analyze various supply chain models and the impact of disruptions caused by the pandemic. At first, it discusses supply chain management and its risks due to pandemics. It then, discusses a case study of Unilever restructuring its supply chain system. The paper also suggests a methodology for supply chain management during pandemic. The outcomes and insights of this paper can be used by decision makers for risk management in supply chains and leads a step for future research.

Purpose Reshoring is one of the supply chain risk management techniques suggested in literature. However, literature suggests that the decision-making involved in reshoring is complex and not fully understood. In the context of the COVID-19 pandemic, reshoring may represent a way to reduce reliance on global sources and improve resilience of their supply chains. This paper aims to explore if the pandemic is driving reshoring decisions and if the pandemic will actually lead to companies reshoring parts of their supply chain. Design/methodology/approach This paper critically engages with senior(-most) supply chain managers from three manufacturing companies as they proceed through reshoring decision-making. This enables to develop experiential knowledge about reshoring decision-making processes and their context, as well as insights into the relevance of existing knowledge about reshoring. While not a full multiple case study, the opportunity to engage directly with senior(-most) supply chain managers as they consider reshoring, enables near real-time learning. Not only is reshoring a very timely topic literature has also called for more event-based empirical research. Further to that, it is hoped that this can complement this special issue and support, in a timely manner, the many researchers that are actively studying the impact of the pandemic on supply chains. Findings Reshoring was being actively considered by all three companies during the research process in Q3 and Q4 of 2020. During this period the pandemic has not yet led to substantial implementation of reshoring, at least by the companies studied in this paper. In response to tariffs on Chinese imports, companies had been diversifying their supply base away from China, but doing so by developing alternative, global sources. Additionally, companies are using alternative risk management techniques, such as supplier collaboration, in the short to medium term. Reshoring decision-making is indeed found to be complex and requires a longer-term time horizon for decision-making and implementation. Logistical challenges and growth in demand do drive a willingness of consumers to pay a premium for locally sourced products. However, when supply normalizes these considerations might lose relevance well before reshoring decision-making and implementation can be completed. Originality/value This paper studies reshoring in a real-world setting, learning directly from insights from industry as they emerge. This paper develops four extensions to existing knowledge, develop these in frameworks and hope that this will support ongoing consideration in industry and support the many researchers that are active in this domain today. This paper also suggests several directions for further research.

This chapter examines the relevance of business continuity to supply chain management. Business continuity has focused on the business processes of individual organizations. A business process in a supply chain can involve multiple discrete organizations. This chapter draws on the approaches used by individual organizations to implement continuity and apply them to a supply chain. Typically, supply chains are dependent on IT and workplace for staff. Both can be impacted in a disaster. If one member of a supply chain is affected, this will affect other organizations in the supply chain, magnifying the impact of the initial disaster. The chapter also examines the issues of service supply chains as well as physical goods. A practical outline plan for the development, auditing, and testing of a continuity plan for a supply chain and its management within an overall supply chain governance is proposed as a starting point for supply chain managers.

Purpose The purpose of this paper is to develop a taxonomy of how companies implement Supply Chain Risk Management (SCRM) in terms of two fundamental approaches: the first emerging from internal actions and operations within companies, and the other involving inter-organizational actions undertaken with external supply chain partners. This taxonomy aims to predict firms’ performance with regard to the frequency of supply chain disruption. Design/methodology/approach A cluster analysis of survey data from 908 firms representing 69 countries together with an analysis of variance. Findings The authors’ analysis demonstrates a clear structure of four different patterns of how companies manage supply chain risks: passive, internal, collaborative, and integral. The authors found that firms pursuing an inter-organizational orientation (collaborative and integral) face the lowest levels of supply chain disruption. On the contrary, strategies which simply concentrate on having greater control of internal operations are not vigorous enough to stop the cascade effect of a disruption at the supply chain level. Furthermore, the excellent performance of integral SCRM strategies also suggests that collaboration between buyers and suppliers ensures the efficacy of internal business continuity plans and security procedures. Practical implications Managers should play an active role in making sure that supply chain management and risk management disciplines evolve together. Obviously, when an exogenous event results in a supply chain disruption, a firm will try to put its operations under control through internal capabilities. But SCRM strategies designed proactively in advance with relevant partners are even more beneficial. Originality/value First, previous studies have limited the analysis of SCRM mainly to its reactive internal initiatives within a firm. This paper takes the SCRM literature beyond the internal focus by considering both internal and inter-organizational efforts and, more importantly, developing a single configurational model to analyze modes of interaction. Second, there is little empirical evidence showing the current situation of SCRM. Research in SCRM has been more qualitative than empirical, especially in global coverage. The research tackles this gap and, based on a broader scope of the samples the empirical findings show a higher level of generalizability.

In the packaging industry, disruptions occurring in the supply chain can impact all the segments and have huge consequences on the operations conducted by the distributors. We are witnesses of an unprecedented crisis caused by the COVID-19 pandemic. It has influenced all layers of the society and forced us to make changes and adjustments to our every-day routine, regulations, economy. Disruptions can undermine the stability of the supply chain, causing business losses. Therefore, identifying the impact of different disruptions on the supply chain is crucial. Here, a timely and quick reaction is of great importance. The current pandemic has caused many disruptions in the industry and has impacted all parts of the supply chains in ways that have not been yet recorded, therefore making it even harder for the companies to respond to new challenges. The changes have not skipped the packaging industry, forcing the manufacturers to rethink their strategies and the consumers to change their views of a safe and reliable product. With the economic expansion, the demand for flexible packaging and has been growing. There are many advantages to flexible packaging. Besides the fact that it creates less environmental impact, it also requires fewer resources compared to traditional packaging production. Disruptions in the supply chains of the flexible packaging industry are one of the major economic concerns during the COVID-19 pandemic, and therefore the topic of this paper. Since the companies in the industry are in desperate need for a new approach regarding risk management and building business resilience, some strategies for overcoming the challenges of the crisis on the flexible packaging market have been presented here.

Along any supply chain, a multitude of more or less critical incidents may prevent a company from obtaining the expected level of logistical performance. Knowing how to anticipate and manage supply chain risks is therefore an important approach to maintain a competitive advantage. The target of this article is to evaluate the impact of the risks in relation to the functioning of a supply chain on its logistical performance. For such needs, a survey was administered with 158 Moroccan manufacturers. The data collected allows to successively measure the impacts of the risks linked to the management of the upstream supply chain, of operational risks and risks linked to the management of the downstream supply chain on the logistical performance.

This study explores the impact that COVID-19 and its preventive measures would have on the plantation sector, covering four important crops—tea, coffee, rubber and cardamom. The study traces the channels through which the pandemic and the lockdown measures would impact the sector. These channels are the disruptions in seasonal operations, in factor and resource supplies; transport, storage and processing; marketing and sales; and demand conditions. These disruptions get manifested in price, quantity and revenue. These are estimated for the four crops separately. The total unrealised revenue due to the lockdown is estimated to be ₹38.4364 billion for the lockdown period from 24 March to 31 May 2020. This does not include the losses that are to be incurred due to the demand decline, supply chain disruptions and price fall that is to be manifested in future. This massive economic disaster is bound to have a severe impact on the plantation economy, especially the small growers and the labourers. Urgent measures need to be taken up to arrest the losses and revive the sector. Yet there is very little in the ‘Atmanirbhar Bharat’ package that would help tide over this economic crisis. Immediate measures aimed at demand rejuvenation, arrest of price fall, restarting of plantation operations and restoring of supply chains is called for. The vantage point of the commodity boards must be exploited to reach out to the stakeholders. JEL classification: M38, Q11, Q13, R11
