Complexity and Self-Sustainment in Disaster Response Supply Chains
研究了灾害响应供应链中的自维持性，即中间环节消耗的物资需由供应链自身提供的情况，通过数学模型分析了自维持性、灾害发生速度、影响分散度与救援成本之间的关系。
Governmental organizations play a major role in disaster relief operations. Supply chains set up to respond to disasters differ dramatically in many dimensions that affect the cost of relief efforts. One factor that has been described recently is self-sustainment, which occurs when supplies consumed by intermediate stages of a supply chain must be provided via the chain itself because they are not locally available. This article applies the concept of self-sustainment to response supply chains. A mathematical model of a self-sustaining response supply chain is developed. Analysis of this model yields insights about the relationships and interactions among self-sustainment, speed of disaster onset, dispersion of impact, and the cost of the relief efforts.
