Why are supply chain disruptions important? Even a relatively small supply
chain disruption caused by a
localized risk event localized risk event may haveconsequences across the consequences across the global economic system global economic system .
Supply chains appear todisperse risk disperse risk between multiple
part es, ut t ey can a soaggregate risk aggregate risk . Global supply chains,
offshoring and outsourcingleads to lesser control overdisruption causes.disruption causes.
As a result, companies are leftonly with control overdisruption consequences.disruption consequences.

Supply chain disruptions in sparse networks The vulnerability of the transportation network vulnerability of the transportation network as part
of the supply chain is of particular interest in countriesin countries
or regions with sparse transportation networksor regions with sparse transportation networks .

Research questions
Does the location reflect on typical supply chain disruptions? What is the critical transportation mode/network/route?
Does the location reflect on supply chain structure? Does a sparse transportation network induce a certain sc structure?
oes e oca on re ec on e compan es prepare ness orcertain disruptions? Situation awareness?
Does the location reflect on mitigation and contingency actions? What level of risk (supply chain disruptions/costs) exists at which
locations?

Robustness, flexibility, resilience Different supply chain
characteristics will result indifferent ways a suply chaindisruption is handled.
A resilient supply chain is,
back to a stable state, althoughnot necessarily to where it wasbefore the disruption.
In business setting the ability
to survive (resilience) is moreimportant than regainingstability (robustness)

Supply Chains vis-a-vis DisruptionFactors that can aggravate or lessen supply chains disruptions:
Supply Chain Design supply chain density supply chain complexity
node criticality
Supply Chain Mitigation Capability adaptive capacity (recovery capability) 1
information sharing/ visibility (warning capability)1

ConclusionIn regions or countries with sparse transportation sparse transportation
networks networks or few transportation mode choices few transportation mode choices thestructure structure or design design of the supply chain, along with theorganization organization and preparedness preparedness become importantfactors in determinin if a com an has an favorable favorable or a
