In SCM theory, robustness and vulnerability are perceived as opposite though not
mature concepts (Wagner and Bode 2006). Disruption can have direct effect on the
organizations’ ability to distribute products into a market and provide critical services
to customers (Bhamra et al. 2011). Vulnerability refers to the capacity of the
system to preserve its structure (Gallopin 2006) or as the extent to which a system is
susceptible to the effects of change (Bhamra et al. 2011). Resilience represents sum
total of vulnerability of a system as well as its adaptive capacity (Dalziell and
McManus 2004). Robustness is mainly considered as the ability of the system to
continue to function in the event of a disturbance (Dong 2006).
