Maintaining viability by rapid supply chain adaptation using a process capability index

ABSTRACT

Unpredictable disruptions of the supply chain, as they have been caused by the Covid-19 pandemic, require a rapid adaptation of the supply chain, i.e., the reconfiguration of processes and structures to re-establish resilience and maintain viability. Promising reconfigurations need to be identified and assessed regarding anticipatable supply chain performance and costs. Nevertheless, a comprehensive comparison of all potential reconfigurations is difficult as several objectives need to be aligned. To support a rapid preselection of the most promising ones, this paper presents the novel approach of a Supply Chain Resilience Analysis (SCRA), which allows to quantitatively evaluate the effectiveness and efficiency of supply chain reconfigurations under disruption to ensure long-term recovery. Key concept of the SCRA is the combination of all relevant metrics into a single Supply Chain Resilience Index (SCRI) that builds upon an adapted process capability index (PCI). The PCI is usually applied in quality management of production processes to assess if a process adheres to specified limits of quality characteristics. In combination with a digital twin of the supply chain, the SCRA methodology can be applied for an automatic pre-selection of supply chain reconfigurations. For verification and validation of the developed methodology and its index, the presented methodology has been applied in a use case of an automotive supply chain. © 2022 Elsevier Ltd
