Firms have learned how to strengthen the resilience of their global supply chains (SC) confront disruptions triggered by severe disasters. However, a new instigator SC disruption, quite unlike any seen in recent times, has now emerged – COVID-19/SARS-CoV-2 virus. We model ripple effect an epidemic outbreak SCs considering velocity pandemic propagation, duration production, distribution and market demand decline. analyse risk mitigation measures potential recovery paths.

Supply chain (SC) disruptions are considered events that temporarily change the structural design and operational policies of SCs with significant resilience implications. The SC dynamics complexity drive such beyond local event node boundaries to affect large parts SC. propagation a disruption through its associated impact is called ripple effect. Previous approaches effect modelling have mainly focused on estimating likelihood disruption; our study looks at consequences. We develop new...

Empirical studies for achieving manufacturing flexibility goals have centered around the uses and advantages of advanced technology. Few examined alternative ways attaining objectives. Strategic sourcing finds mention in literature as a potential route to flexibility. However, little empirical evidence exists validate this view. Literature also describes multidimensional concept but fails adequately examine synergies among different dimensions. This research investigates influence strategic...

Abstract This paper analyzes the interrelationships between international sourcing decisions, strategies, and supplier performance. We first discuss effect of global competition on need for firms to seek suppliers, present a number taxonomies that describe evolution supply base development. The deployment different commodity strategies (e.g., information sharing, single vs. multiple sourcing, contracts, partnering) in conjunction with is also reviewed. In second half paper, we examine set...

Abstract The role of employee safety in supply chain performance has inexplicably been overlooked by operations management literature. With a few notable exceptions, there is no guidance the literature for managers trying to understand that at their own or suppliers could play quality outcomes.

Abstract Manufacturing flexibilities improve a firm’s ability to react customer demands without incurring excessive time and cost penalties. While development of manufacturing is desirable indeed critical for some firms, exploiting the flexibility capabilities achieve tangible firm‐level performance outcomes through effective execution becoming increasingly important. This paper presents conceptual model that introduces two new constructs: competence as distinct from flexibility. Based on...
