Petri nets-based method for operational risk analysis in supply chains based on timeliness and recovery time

Abstract

Recently, supply chain risk management has been attracting growing attention. Therefore, various methods, tools, and practices have been developed in this area. However, they usually are focused on the direct consequences of disruptions occurring in supply chains. Thus, the purpose of this article is to present an operational risk analysis method for supply chains, in which consequences of an adverse event occurrence are assessed based on two measures: (1) the direct consequences (disruption) of supply processes to customers, and (2) recovery time for a supply system. Based on research findings, we introduced a Petri nets model for mapping material flows along a supply chain. We implement the proposed analysis method in a selected company from the automotive industry. The performed final discussion confirmed the relevance of distinguishing the direct and indirect consequences of the risk assessment. It was also suggested that the results’ interpretation could be two-fold, which may be necessary for appropriate risk management tool selection.

Following ESREL 2021 and this special session, this special section including five papers 1–5 was collated with the objective of highlighting and disseminating current state-of-the-art methods and their practical applications in reliability, risk, and resilience engineering for structures and infrastructures.…”

“…In Wu and Zhang, 4 the issue of infrastructure resilience is considered from the point of view of asset management, and, more specifically, the paper proposes a joint modeling framework to integrate condition monitoring information for both operation and maintenance of systems. Finally, in Skorupski et al, 5 the authors address the problem of managing critical production infrastructures and supply chains. They propose a new approach to the operational risk analysis for highly-coordinated resilient supply chains subjected to adverse events, based on a Petri-nets assessment model.…”
