Logistics for Large-Scale Disaster Response: Achievements and Challenges

Applying Network Flow Optimization Techniques to Improve Relief Goods Transport Strategies under Emergency Situation

“…We see no change for our optimal solution after we increase the value of 2 K to over 210, as shown in Table 4 have been delivered to RED (i.e. region 11), resulting in a decrease in k w and jk v at region 11 to 211.34 m 3 . Figure 4 illustrates the routes to be travelled for delivering drinking water from RES to RED in the final optimal solution (i.e.…”

“…We know that reducing the maximum demand gap by a certain amount means increasing the delivery by the same amount from some RES to other RED with the minimum transportation cost. Therefore, we can see from 3 . Now, regarding the "turning" coefficient value as between 2 120 K = and 2 130 K = , this implies that the minimum transportation cost for a unit amount of water supply from some RES to other RED occurs between region 9 and region 11 with a total distance 63 69 129 + = .…”

“…As we can see from the column of max-gap which represents the amount of remaining maximum demand gap in Table 7, when all the road segments are available ( ) 0.00 ij P = , the remaining demand gap of drinking water in region 11 becomes 211.34 m 3 , that is after receiving aid of 71.15 m 3 from RES. However, increasing the probability of broken road segments, the remaining demand gap also increases.…”

A Markov decision process model of allocating emergency medical resource among multi-priority injuries

“…At the meantime, the objectives and decision criteria not only reflect the attitudes and principles of decision makers towards decision problems, but also act as measurements to assess various schemes or schedules (Jiang et al, 2012).…”

“…Larson et al (2006) analysed five major emergencies from 1995 to 2004, and showed that large-scale disasters have a much more significant impact on society. Jiang et al (2012) analysed and summarised the current literature on emergency management, and they elaborated the key distinct characteristics of large-scale disasters from seven viewpoints: mass scale, severe consequences, multi-agency involvement, time pressure, demand surge and resource shortage, great uncertainty and infrastructure damage. So the largescale disasters may cause large number of casualties and property damage, and warn people the importance of disaster warning, emergency rescue and disaster reconstruction.…”
