Summative framework of disaster dimensions and independent variables

Dimension	Factors	Design implications
Speed of onset	Speed dictates rate of demand increase Faster speeds may warrant a more responsive HRSC design, whereas slower speeds may allow more efficient HRSCs to be designed	Rapid onset events require swift deployment to meet demand surges Pre-positioning inventory allows for rapid deployment Slower onset events allow for cost-effective HRSCs to be designed to meet more stable demand patterns
Time horizon	HRSCs may be finite or a permanent fixture of a system	Finite supply chains have different operational requirement than establishing permanent fixtures Permanent supply chains may require greater investment into a system through local training and new infrastructure
Spatial concentration	Determines the degree of space upon which a disaster unfolds	Large geographic boundaries require dispersed HRSCs Event such as cyber-attacks requires immediate deployment with unique design that transcends geography
Affected population needs	End-user requirements can be homogenous or heterogeneous in nature	Design considerations, by nature, increase in complexity when product mix is increased Degree of heterogeneity is often informed by socio-political factors that increase the complexity of HRSC operations
Perceived probability of occurrence	Influences decision making due to subjective biases Has capacity to make system prepared/ill prepared for event depending on known nature of threat	High perceived probability of occurrence allows for preparedness and mitigation strategies to be developed Low perceived probability may result in slow deployment of flexibility and contingency strategies due to reluctance of preparatory investment
Perceived magnitude of consequence	Influences the manner in which pre-event system environmental factors (such as redundancies) are developed Influenced by perceived probability	Severe perceived magnitude of consequence may influence inventory prepositioning strategies for rapid deployment
