An Effective Disaster Management System Essay

Good Essays

This exploration, is aimed to develop an effective disaster management system that can be used efficiently to provide emergency medical care to disaster effected areas. During an emergency, it’s very important to be quick at providing the medical care needed in the fastest way possible. There are usually different disaster zones and medical care providers must find the quickest path to reach all locations. Path analysis is required to examine all the routes possible, and find the most suitable one.

From the view of an emergency response system, it is most important to find the shortest path from rescue sites to disaster areas through a road network. In order to take prompt actions, it’s important to construct an appropriate transportation network. This is where graph theory comes in.

Graphs are defined by a set of vertices and a set of edges, where each edge connects two of its vertices. For the example below, each of the dots is a vertex, while each of the lines is an edge.

Often, the vertices and edges are labelled with letters, for example {v1, v2, v3,…,vn} for n number of vertices and {e1, e2, e3,…,em} for m number of edges. The example graph shown above after labelling would look something like this:

It should be known that because the graph is an undirected graph (i.e. there is no restriction to the direction of the edges), it is represented by an unordered pair rather than an ordered pair. That means the two edges (e1, e2) and (e2, e1) are the same. However,
