Recent natural disasters (e.g. hurricanes, earthquakes) andmanmade crises (e.g. war, political disturbance) havehighlighted the vulnerability of communities to unstableconditions. Reaching displaced people in crisisconditions depends on the effectiveness of the supplychain and its management systems. Hurricane Katrina’simpact on New Orleans (September 2005) highlightedweaknesses of supply chain systems rather than physicaldistribution shortcomings; the Kashmir earthquake(October 2005) highlighted problems of remoteness andphysical capability to deliver aid. A number of modelshave been proposed (e.g. [1],[2] to which most responsesystems or mechanisms broadly conform, but within theseapproaches wide variations can be identified. The authorsof this paper have developed a model to accommodate thedecision making process as well as the wide range ofcircumstances which, in practice, can impact on theworkings of emergency supply chains. This paperrepresents an attempt to test the model against theconditions which prevailed in Thailand following theDecember 2004 Tsunami. This provides insights to thesusceptibility of such supply chains to a wide range ofpressures which can translate to sub-optimal solutions interms of cargo routing, modes and methods employed,wastage rates, reliability of schedules, cost and otherparameters.
