Purpose: This paper examined supply chain disruptions in the manufacturing industry in South Africa and how additive manufacturing technology was used to help deal with disruptions encountered. Design/methodology/approach: The study adopted a qualitative research approach in order to meet the objectives of the study. A total of ten (10) managers of conventional manufacturing firms and ten (10) managers of 3D printing firms in Free State, South Africa participated in the study through the use of a purposive sampling technique. Interview guides were used in the collection of data. Data transcriptions and thematic analysis were used to analyze data gathered from the interviews. Findings: The results of the study showed that 3D printing contributed positively in dealing with manufacturing disruptions that were encountered by manufacturing firms in Free State, South Africa through the production of components and spare parts that were broken down in manufacturing machinery/plants. From the study, the researchers recommend that 3D printing technology should be adopted by manufacturing firms because of its practicality in providing manufacturing support and production continuity even in supply chain disruptive experiences caused by pandemics such as Covid-19. Originality/value: The study proves that due to the versatility of the 3D printing technology it could be used to minimize the effect of supply chain disruption during cries such as the Covid-19 pandemic. One of the unique contributions of the current study is the realization that additive manufacturing was not of much relevance to the generic supply chain challenges encountered in supply chain activities, but rather very relevant in helping to prevent disruptions of the manufacturing process by improvising spare parts at the peak of the Covid-19 pandemic.

This paper explains the evolving role of the local supply chain across different disruption scenarios. A systematic literature review of 91 papers from 33 journals supports definition of the local supply chain and explication of benefits before, during and after COVID-19 disruption. Resilience emerges as the prevalent benefit at each stage, but to varying scales. In the pre-COVID-19 era, where the local supply chain serves as a back-up approach to the more dominant global supply chain, localisation's capacity to absorb change promotes resilience to mitigate low-magnitude disruption. At initial outbreak of COVID-19 disruption the local supply chain was necessitated as an emergency response to the untenability of global operations, demonstrating transformational resilience to survive. As disruption continued, the local supply chain upscaled and adapted to recover. In the post-COVID-19 era, resilience is expected to remain a strategic priority, promoting continued investment in local operations to thrive with embedded resilience. As a result, the COVID-19 pandemic welcomed a point of transition for the local supply chain as capacities and benefits are revaluated and localisation recognised as critical in developing resilient supply networks for the future. This study consolidates this evolution to offer a propositional framework showcasing the local supply chain across different disruption scenarios. This offers long overdue definition and explanation of the local supply chain and its relationship with resilience, addressing an existing lack of academic attention and encouraging alignment of local-versus-global decisions with changing strategic priorities.

The COVID-19 pandemic has continued to result in severe disruptions to food supply chains. In this research, we present a simulation study on the impact of the COVID-19 pandemic on food supply chains and their sustainability using the lobster industry in Nova Scotia, Canada, as an example. The main contributions of this paper are twofold. First, it analyzes how the pandemic has negatively disrupted lobster supply chains and their sustainability. Second, it demonstrates how a simulation-based methodology based on the software AnyLogistix can be applied to examine the effects of a pandemic on food supply chains. We show the impacts of the COVID-19 pandemic from four perspectives: production-inventory dynamics, customer performance, financial performance, and lead-time performance. Our findings include the following. First, the pandemic has created a backlog problem for the live lobster industry. Second, it has significantly increased the lead time of the lobster supply chain. Overall, this research can help the government and trade organizations to devise appropriate policies to reduce the negative impacts of the pandemic on food supply chains and their sustainability.
